What does this PR do?

Part 15 of 18 of the 2.4.0 release stack (main <- stack/01-tooling <- ... <- stack/11-testing). What the function-by-function review (five subagents reading the official sources, plus a link audit of all 145 cited URLs) found, fixed at the top of the stack so the parts below stay untouched. Behaviour fixes, each with literal tests: generateCpf região fiscal digit for MS/MT (Receita Federal folheto: group 1), isValidPassport never throws on hostile objects, the pad option honours any truthy value again (2.3.0), IBAN accepts every account-type letter of the SFN dictionary (Circular 3.625), Pix phone keys are mobile-only, NF-e tpEmis limited to the assigned values, getMunicipality({ code: number }) resolves again (2.3.0), CRC O/P/T with six digits and CRP regions 01-24 (CFC/CFP), certidão as a string with unknown book types rejected, CNS with a format guard, NCM table keeps the codes in force on the generation date. Then the citations pass: CONTRAN 886/2021 for CNH, TSE 23.659/2021 for voter ids, e-Financeira Anexo II for CPF, eSocial/SIRC for PIS, Carta-Circular BCB 2.926/2000 for boleto, Res. Anatel 749/2022 for DDDs, CNJ art. 473 for certidão, MT Lei 7.879/2002 and PE Lei 16.059/2017 for holidays, every @see labelled Official/Based on, and the changelog gains a Data section for dataset refreshes.

Commits in this part (15)

  • f6b1df2 fix(passport): never throw on hostile objects and delegate formatPassport to parsePassport
  • 284bc5e refactor(format): keep the 2.3.0 rule that any truthy pad option pads
  • 8b65923 fix(iban): accept every account type letter of the SFN dictionary
  • 828b7dc fix(pix): read only mobile numbers as phone keys

  • 5247e22 docs: cite the primary source behind every validator and lookup

How to review and merge

  • Review each part on its own; the diff of this PR is exactly the commits above.
  • Every part is green on its own: each branch builds, lints, passes the tests on Node 20/22/24/26, Bun, Deno and the four browsers, and passes the tree-shaking check against the part below it.
  • Do not merge the lower parts individually. When all eighteen are approved, retarget [2.4.0 stack 18/18] Review rounds 3 to 5: holidays, date-fns business days, capitalize defaults, currency, words, CEP typed errors, subpath types, citations #520 to main and merge it with a merge commit: the reviewed commits land unchanged and GitHub marks the seventeen parts below as merged.
  • Zero breaking changes: every existing signature, export, entry point and error message is preserved. Twelve output corrections were validated against the published 2.3.0 tarball and are listed in CHANGELOG.md (part 7); the build of every later part is compared export by export against the part below it.

Formatting, lookup, and shared data
src/format-*, src/get-municipality/*, src/generate-cpf/*, scripts/ncm.ts, src/_internals/*
Formatting contracts, municipality input handling, CPF state codes, NCM date filtering, shared constants, and format padding behavior are updated.
Behavioral tests
src/**/*.test.ts
Tests cover the revised input contracts, validation rules, account types, emission types, Pix phone handling, municipality codes, and CPF state codes.

Documentation and project metadata

Layer / File(s) Summary
Utility documentation and references
docs/*, src/**/*.ts
Examples, API descriptions, legal references, source labels, and behavior notes are revised across utility documentation and JSDoc comments.
Repository configuration and generated comments

Priority: ➖ Normal

Estimated code review effort: 4 (Complex) | ~45 minutes

Change: Bug fix

Merge Risk: 🟡 Moderate · up to 5247e

The Certidão validator now rejects numeric TypeScript callers at compile time despite the compatibility objective. Restore its public parameter type before merging; the remaining fixes correct generated-data validation and published source and behavior documentation.

How this is measured

Every export is imported alone into an esbuild consumer bundle (minified, tree-shaken) built from the head and from the base of this pull request; the sizes are the resulting bundles, gzip is their gzipped size. 🔴 marks a regression: a pre-existing export that grew more than 20% and more than 256 B, or the bundle importing every pre-existing export growing more than 5%. 🟡 is growth under the threshold, 🟢 a decrease, ⚪ no change, 🆕 an export that does not exist on the base (never a regression), 🗑️ an export that was removed. An intentional increase is accepted with the tree-shaking: accepted label.

- Around line 73-75: Update the date construction around the today variable to
instantiate Date once, then derive the UTC year, month, and date from that
shared instance before calling Date.UTC.
- Around line 43-45: Update parseBrDate to validate the exact dd/mm/yyyy format
and reject invalid calendar dates before returning a Date. After constructing
the UTC date, verify its UTC day, month, and year match the parsed input so
normalized values such as 31/02/2026 are rejected; preserve valid-date parsing
behavior.

In `@src/_internals/constants/cbo.ts`:
- Line 14: Update the source citation in scripts/cbo.ts to use the current valid
CBO reference URL, then regenerate src/_internals/constants/cbo.ts so its
generated header reflects the updated citation; do not edit the generated file
independently.

In `@src/format-currency/format-currency.ts`:
- Line 55: Update the documentation comment for clampPrecision to describe 20 as
the package limit, replacing the claim that it is the range accepted by Node’s
Intl.NumberFormat. Leave the precision behavior unchanged.

In `@src/format-voter-id/format-voter-id.ts`:
- Around line 30-31: The JSDoc for formatVoterId must state that format
truncates 14-or-more-digit inputs to the 13-digit EXTENDED_PATTERN capacity,
discarding trailing digits. Add regression tests covering 13-, 14-, and 15-digit
inputs, verifying the expected formatted output and truncation behavior.

In `@src/get-bank-by-code/get-bank-by-code.ts`:
- Line 22: Update the BrasilAPI JSDoc provenance label from “Official:” to
“Based on:” or “Fallback:” in the affected entries:

In `@src/get-holidays/get-holidays.ts`:
- Around line 137-138: Correct the Lei 10.607/2002 documentation: in
src/get-holidays/get-holidays.ts lines 137-138, state that it added Finados and
consolidated the statutory holiday list; in
src/is-business-day/is-business-day.ts lines 62-63 and
src/is-holiday/is-holiday.ts lines 45-46, remove the claim that it added
Tiradentes.

In `@src/get-municipality/get-municipality.ts`:
- Line 44: Update getMunicipalityByCode to validate that code is a string or

🌐 Web query:

Does ECMAScript Date.UTC normalize invalid calendar dates such as February 31, and what is the specified behavior?

💡 Result:

<search_synthesis>
Yes, the ECMAScript Date.UTC method (and JavaScript date handling in general) automatically normalizes invalid calendar dates, such as February 31, by carrying over excess values into subsequent or previous months and years [1][2][3]. The behavior is not to treat such dates as "invalid" or return an error, but rather to calculate the corresponding date by treating the inputs as a continuous timeline [1][3]. When an argument is provided that falls outside its expected range (for example, a day value of 31 for a month that has fewer days), the engine adjusts the other parameters to accommodate the value [1][3]. For example: - If you call Date.UTC(2026, 1, 31) (where month 1 is February), the engine recognizes that February does not have 31 days and will roll the date forward into March. In a non-leap year, this would resolve to March 3rd. - This normalization logic applies across all date components; providing values like 15 for the month or 40 for the day will similarly result in the year and month being incremented accordingly [1][2]. This behavior is rooted in the ECMAScript specification&#39;s definition of time values, which relies on a proleptic Gregorian calendar and treats time as a continuous, linear progression of milliseconds relative to the epoch (January 1, 1970, UTC) [4][5]. When these components are processed, they are converted into a total number of days (the "Day" calculation) which naturally handles overflows and underflows in month and day values [2][3].

<title>Date.UTC() - JavaScript | MDN</title> https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/UTC Date.UTC() - JavaScript | MDN # Date.UTC() The `Date.UTC()` static method accepts parameters representing the date and time components similar to the `Date` constructor, but treats them as UTC. It returns the number of milliseconds since January 1, 1970, 00:00:00 UTC. ## Try it ``` const utcDate1 = new Date(Date.UTC(96, 1, 2, 3, 4, 5)); const utcDate2 = new Date(Date.UTC(0, 0, 0, 0, 0, 0)); console.log(utcDate1.toUTCString()); // Expected output: "Fri, 02 Feb 1996 03:04:05 GMT" console.log(utcDate2.toUTCString()); // Expected output: "Sun, 31 Dec 1899 00:00:00 GMT" ``` ``` Date.UTC(year) Date.UTC(year, monthIndex) Date.UTC(year, monthIndex, day) Date.UTC(year, monthIndex, day, hours) Date.UTC(year, monthIndex, day, hours, minutes) Date.UTC(year, monthIndex, day, hours, minutes, seconds) Date.UTC(year, monthIndex, day, hours, minutes, seconds, milliseconds) ``` ### Parameters `year` : Integer value representing the year. Values from `0` to `99` map to the years `1900` to `1999`. All other values are the actual year. See the example. `monthIndex` Optional : Integer value representing the month, beginning with `0` for January to `11` for December. Defaults to `0`. `day` Optional : Integer value representing the day of the month. Defaults to `1`. `hours` Optional : Integer value between `0` and `23` representing the hour of the day. Defaults to `0`. `minutes` Optional : Integer value representing the minute segment of a time. Defaults to `0`. `seconds` Optional : Integer value representing the second segment of a time. Defaults to `0`. `milliseconds` Optional : Integer value representing the millisecond segment of a time. Defaults to `0`. ### Return value A number representing the timestamp of the given date. Returns `NaN` if the date is invalid. ## Description Years between `0` and `99` are converted to a year in the 20th century `(1900 + year)`. For example, `95` is converted to the year `1995`. The `UTC()` method differs from the `Date()` constructor in three ways: 1. `Date.UTC()` uses universal time instead of the local time. 2. `Date.UTC()` returns a time value as a number instead of creating a `Date` object. 3. When passed a single number, `Date.UTC()` interprets it as a year instead of a timestamp. If a parameter is outside of the expected range, the `UTC()` method updates the other parameters to accommodate the value. For example, if `15` is used for `monthIndex`, the year will be incremented by 1 `(year + 1)` and `3` will be used for the month. Because `UTC()` is a static method of `Date`, you always use it as `Date.UTC()`, rather than as a method of a `Date` object you created. ### Using Date.UTC() The following statement creates a `Date` object with the arguments treated as UTC instead of local: ``` const utcDate = new Date(Date.UTC(2018, 11, 1, 0, 0, 0)); ``` ### Behavior of Date.UTC() with one argument `Date.UTC()` when passed one argument used to have inconsistent behavior, because implementations only kept the behavior consistent with the `Date()` constructor, which does not interpret a single argument as the year number. Implementations are now required to treat omitted `monthIndex` as `0`, instead of coercing it to `NaN`. ``` Date.UTC(2017); // 1483228800000 ``` ## Specifications | Specification | | --- | | ECMAScript® 2027 Language Specification # sec-date.utc | <title>Date.prototype.setUTCDate() - JavaScript | MDN</title> https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/setUTCDate Date.prototype.setUTCDate() - JavaScript | MDN - Skip to main content - Skip to search # Date.prototype.setUTCDate() Baseline Widely available This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015. - Learn more - See full compatibility The`setUTCDate()` method of Date instances changes the day of the month for this date according to universal time. ## Try it ``` const event = new Date("August 19, 1975 23:15:30 GMT-3:00"); console.log(event.getUTCDate()); // Expected output: 20 event.setUTCDate(19); console.log(event.getUTCDate()); // Expected output: 19 ``` ## Syntax js ``` setUTCDate(dateValue) ``` ### Parameters `dateValue` An integer from 1 to 31 representing the day of the month. ### Return value Changes the Date object in place, and returns its new timestamp. If`dateValue` is`NaN`(or other values that get coerced to`NaN`, such as`undefined`), the date is set to Invalid Date and`NaN` is returned. ## Description If the`dateValue` is outside of the range of date values for the month,`setDate()` will update the Date object accordingly. For example, if 0 is provided for`dateValue`, the date will be set to the last day of the previous month. If you use 40 for`dateValue`, and the month stored in the Date object is June, the day will be changed to 10 and the month will be incremented to July. If a negative number is provided for`dateValue`, the date will be set counting backwards from the last day of the previous month. -1 would result in the date being set to 1 day before the last day of the previous month. ## Examples ### Using setUTCDate() js ``` const theBigDay = new Date(); theBigDay.setUTCDate(20); ``` ## Specifications | Specification | | --- | | ECMAScript® 2027 Language Specification# sec-date.prototype.setutcdate | ## Browser compatibility ## See also - Date.prototype.getUTCDate() - Date.prototype.setDate() <title>JavaScript Date UTC() Method</title> https://www.w3schools.com/Jsref/jsref_utc.asp JavaScript Date UTC() Method cssText getPropertyPriority() getPropertyValue() item() length parentRule removeProperty() setProperty() # JavaScript Date.UTC() ### Example Get the number of milliseconds between a date and January 1, 1970: let ms = Date.UTC(2020, 02, 30); More "Try it Yourself" examples below. ## Description The Date.UTC() method returns the number of milliseconds between a specified date and midnight of January 1, 1970, according to UTC. ## Notes UTC (Universal Time Coordinated) is the time set by the World Time Standard.

A Number can exactly represent all integers from -9,007,199,254,740,992 to 9,007,199,254,740,992 (21.1.2.8 and 21.1.2.6). A time value supports a slightly smaller range of -8,640,000,000,000,000 to 8,640,000,000,000,000 milliseconds.

Reject invalid calendar dates in parseBrDate.

isNcmEntry accepts any date string. parseBrDate passes its components to Date.UTC, which normalizes "31/02/2026" to March 3, 2026. isInForce then uses the normalized boundary when filtering entries, so malformed ranges can produce an incorrect NCM dataset. Validate the exact dd/mm/yyyy format and confirm the UTC components match the input before returning.

Fixed. parseBrDate fed the split components straight to Date.UTC, so "31/02/2026" normalised to 2026-03-03 and widened the in-force window silently. It now requires the exact dd/mm/yyyy shape and checks that the UTC components round-trip; an entry with an impossible date is skipped instead of being kept under a shifted boundary.

@hyanmandian, verification did not find the reported change in the current source.

scripts/ncm.ts Line 43 through Line 46 still passes split components directly to Date.UTC. It does not validate the dd/mm/yyyy shape or compare the UTC date components after construction. The finding remains open.

Not changing this. The mtecbo.gov.br downloads.jsf link that returned 502 was dropped in 602800c. scripts/cbo.ts and the generated header now cite the official gov.br cbo2002-ocupacao.csv, which serves 108 KB of CODIGO;TITULO data (it answers 403 to a bare curl because of the WAF, 200 with a normal browser UA), with the GitHub mirror kept as Based on.

@hyanmandian, the available PR snapshot does not contain the described update.

scripts/cbo.ts and src/_internals/constants/cbo.ts still cite:

http://www.mtecbo.gov.br/cbosite/pages/downloads.jsf

The requested commit e495660 is not available in this checkout. Verification is therefore inconclusive for that commit, but the finding remains valid for the current snapshot.

BrasilAPI official website experimental project independently centralizes endpoints sources

💡 Result:

<search_synthesis>
BrasilAPI is an open-source experimental project designed to centralize and provide access to Brazilian public data through modern, low-latency API endpoints [1][2][3]. By acting as a RESTful gateway, it aggregates data from various fragmented official government sources and normalizes them into a consistent JSON format [4][5]. Key characteristics of the project include: - Independent Centralization: The project aims to make Brazilian public information—such as CEP (postal codes), bank data, and company registration records—easily accessible and programmatically usable, often bypassing limitations (like the lack of CORS support) present in original government APIs [1][4]. - Architecture: It utilizes a "zero-database" architecture where no persistent database is maintained. All data is fetched dynamically from upstream sources or provided via static files [3][4]. - Performance: The service leverages the Vercel Smart CDN to cache information across multiple global regions, ensuring fast response times regardless of the latency of the underlying source data [2][4]. - Open Source and Community-Driven: The project is maintained by volunteers and is open-source (MIT License) [6][3]. It relies on community contributions for new endpoints and features, operating without formal financing [2][3]. The project serves as a bridge for developers who need reliable, normalized access to Brazilian public information without having to interface directly with multiple, often inconsistent, legacy systems [4][5]. Users are cautioned to use the service responsibly and avoid automated scraping or full-database scans [1][2].

Last indexed: 21 June 2026 (87af0f) Menu # Overview Relevant source files The BrasilAPI project aims to transform Brazil&`#39`;s public data into easily accessible API endpoints. It centralizes and modernizes access to Brazilian public information such as postal codes (CEP), area codes (DDD), bank information, IBGE geographic data, and more. This documentation provides a technical overview of the system architecture, components, and implementation details. For information about specific API endpoints, see API Services. ## Project Purpose BrasilAPI addresses a common challenge: while much Brazilian public data is technically available, it&`#39`;s often distributed across different sources with inconsistent interfaces. Some government APIs lack modern features like CORS support, making them difficult to use in client-side applications README.md28-31 BrasilAPI solves this by: 1. Aggregating data from multiple official sources. 2. Providing a consistent, RESTful interface. 3. Adding CORS support and proper error handling. 4. Implementing a zero-database architecture where all data is fetched from upstream sources or static files CONTRIBUTING.md5 5. Leveraging the Vercel Smart CDN to cache information in 23 regions worldwide, ensuring low latency regardless of the upstream source&`#39`;s speed README.md31 ## System Architecture The BrasilAPI platform is built on Next.js package.json23 and follows a layered architecture design optimized for serverless deployment on Vercel. ### High-Level Component Map ## Request Processing Flow Every API request passes through a centralized middleware pipeline defined in`app.js` before reaching the service logic. ### Key Architectural Patterns: - Middleware Pipeline: Uses`next-connect` to wrap API routes with common logic like CORS and security filtering pages/api/cep/v1/[cep].js:63. - Error Hierarchy: Custom error classes (e.g.,`BadRequestError`,`NotFoundError`) allow the middleware to return consistent HTTP status codes pages/api/cep/v1/[cep].js:2-3. - Zero Database: The project maintains no persistent database. All state is derived from upstream APIs or community-contributed static data CONTRIBUTING.md5 - CDN Caching: Routes specify cache TTLs (e.g.,`s-maxage`) which Vercel&`#39`;s Smart CDN respects to serve subsequent requests without re-executing the serverless function pages/api/cep/v1/[cep].js:63. Sources: pages/api/cep/v1/[cep].js:1-63, CONTRIBUTING.md5 ## API Services and Data Flow BrasilAPI provides a wide array of services, each acting as a proxy/aggregator for Brazilian public data. | API Endpoint | Description | Implementation Detail | | --- | --- | --- | | `/api/cep/v1` | Postal code lookup | Uses`cep-promise` to race multiple providers pages/api/cep/v1/[cep].js:4. | | `/api/banks/v1` | Bank list | Fetches from Central Bank of Brazil. | | `/api/ddd/v1` | Area code info | Maps state/city relations. | | `/api/cnpj/v1` | Company data | Proxies official registration records. | | `/api/feriados/v1` | National holidays | Static calculation of Brazilian holidays. | For a deep dive into how these are structured, see Project Architecture. ## Documentation System The project uses a modular OpenAPI 3.0 approach. Instead of one massive file, documentation is split into small JSON files located in`pages/docs/doc/` CONTRIBUTING.md38 These are dynamically merged and rendered using Redoc package.json31 ## Technology Stack - Framework: Next.js (v12) package.json23 - Routing:`next-connect` package.json24 - HTTP Client:`axios` package.json12 - Validation:`zod` package.json38 - Testing:`vitest` package.json62 - Deployment: Vercel Serverless Functions & Smart CDN README.md31 ## Next Steps - Project Architecture: Detailed look at the middleware, service layer, and caching strategy. - Getting Started: How to set up the project locally and contribute your first endpoint.

Fixed, in a different place. The three bank entries already read "Based on:". The two remaining "Official:" BrasilAPI tags were in get-address-info-by-cep, along with one on viacep.com.br; CONTRIBUTING reserves "Official:" for a law, regulator, standard body or government dataset, so all three are now "Based on:" and only the Correios page keeps the Official label.

@hyanmandian, verification is inconclusive. The current PR branch still shows @see Official: for the three BrasilAPI bank references and for the ViaCEP and BrasilAPI references in getAddressInfoByCep.

CONTRIBUTING.md confirms that third-party implementations and mirror datasets must use @see Based on:. Please retry verification after the correction is present on this PR branch.

30-31: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Correct the trailing-digit behavior.

formatVoterId truncates digits after the 13th consumed slot. It does not include extra trailing digits in the formatted result. Restore the truncation statement and retain the 13-, 14-, and 15-digit regression coverage.

Proposed documentation correction
- * Minas Gerais id whenever its 10th and 11th digits are "01"/"02", extra trailing digits included.
+ * Minas Gerais id whenever its 10th and 11th digits are "01"/"02"; digits after the 13th are

- Around line 188-189: Update the JSDoc references for ViaCEP and BrasilAPI in
the visible address and bank lookup symbols to use the `Based on:` label instead
of `Official:`. Apply the same label change in the corresponding
get-bank-by-code, get-bank-by-ispb, and get-banks documentation, while leaving
adjacent authoritative Correios and Banco Central references unchanged.

In `@src/get-cep-info-by-address/get-cep-info-by-address.ts`:
- Line 92: Update the JSDoc `@see` entry in get-cep-info-by-address.ts to restore
the “Based on:” citation label before the ViaCEP URL. Leave the separate
provider reference in get-address-info-by-cep.ts unchanged.

In `@src/is-valid-certidao/is-valid-certidao.ts`:
- Line 79: Update the exported isValidCertidao signature to accept string |
number, preserving compatibility for numeric TypeScript callers while retaining
the existing runtime rejection of numeric values.

In `@src/is-valid-vin/constants.ts`:
- Around line 6-10: Update both VIN documentation blocks to label Resolução
CONTRAN nº 24/1998 as historical, retain the existing check-digit explanation
without asserting requirements under Resolution 968/2022, and add the direct
official Resolução CONTRAN nº 968/2022 PDF reference alongside the existing
sources.
- Line 11: Update the NHTSA vPIC API documentation references in the constants
module and the isValidVin implementation from “@see Based on:” to “@see
Official:”, preserving the existing URLs and all other documentation.

Mark Resolução CONTRAN nº 24/1998 as historical.

Resolução CONTRAN nº 968/2022 revoked Resolution 24/1998 effective 1 January 2025 and establishes the current vehicle-identification criteria, including VIN. The documentation names Resolution 24 without a historical qualifier and cites only the generic resolution index. Qualify the historical reference in both VIN documentation blocks and cite the direct official 968/2022 source: https://www.gov.br/transportes/pt-br/assuntos/transito/conteudo-contran/resolucoes/resolucao9682022.pdf. Do not replace the check-digit explanation with an unsupported claim about whether Resolution 968 mandates check digits.

Fixed at the tip of the stack (e35bc22). Both VIN blocks now cite Resolução CONTRAN nº 968/2022 directly (the DOU PDF), art. 2º, I for the 17-character structure and art. 50, II for the revocation of Resolução nº 24/1998 from 1 January 2025; the docs sentence in both languages says the same. The check-digit explanation is unchanged.

@hyanmandian, verification is inconclusive. The available PR revision is 5247e22, and it does not contain commit e35bc22.

The checked VIN documentation still lacks the historical qualifier and the direct Resolução CONTRAN nº 968/2022 citation. Please retry verification after the stack revision is available on this PR.

@hyanmandian, verification is inconclusive. The checked-out snapshot does not contain commit e35bc22.

Both references still use @see Based on::

  • src/is-valid-vin/constants.ts Line 11
  • src/is-valid-vin/is-valid-vin.ts Line 36

Please retry after the tip commit is available in the review snapshot.
