@br-validators/core

The Brazilian document validation library for TypeScript.
Validate, format, and generate CPF, CNPJ (including the new alphanumeric format), NF-e, BR Code PIX, boleto, IE (all 27 states), EAN barcodes, CNIS/NIT, ANP fuel prices, and 20+ more — zero dependencies, fully typed, never throws.

npm install @br-validators/core

Try it now → doc-raiz-playground.vercel.app
CLI → npm install -g @br-validators/cli

⚠️ The unscoped br-validators on npm is a different package. Use @br-validators/core.

Why this library

Every Brazilian SaaS eventually reinvents CPF validation — usually wrong.
@br-validators/core implements each algorithm from its official primary source (Receita Federal, Bacen, CONTRAN, TSE, SEFAZ, FEBRABAN, Anatel) so you don't have to.

• ✅ CNPJ alfanumérico — new RFB format (effective July 2026), ready now
• ✅ 21+ document types — CPF, CNPJ, CEP, NF-e chave, processo judicial CNJ, BR Code PIX, boleto (cobrança + arrecadação), CNH, RENAVAM, placa, PIS/PASEP, CNIS/NIT, EAN-8/EAN-13, PIX key, cartão de crédito, IE (27 UFs), IE produtor rural, título de eleitor, telefone, + platform APIs above
• ✅ Zero runtime dependencies — pure TypeScript logic, no HTTP calls
• ✅ Never throws — every function returns { ok: true, value } | { ok: false, message, code }
• ✅ Tree-shakeable — subpath imports per document type
• ✅ Reference data — IBGE (municipalities + NF-e cMunFG), Bacen banks, DDD lookup, national holidays, CNAE, CFOP, CST, LC 116, NCM, IBPT tax burden, Simples Nacional, CBO, natureza jurídica, NBS, CEST, eSocial categorias, CNPJ motivos, moedas, PTAX cotações, países Bacen, NF-e cUF, IRPF / INSS tables, SELIC meta, ISS municipal (top 500 PIB), Incoterms, portos, aeroportos, ANP fuel prices (LPC) — embedded offline with daily freshness (DATA-FRESHNESS.md; ANP weekly)
• ✅ ESM only, Node ≥ 18, works in browser, Bun, Deno

Quick start

import { validateCpf, formatCpf } from '@br-validators/core';

validateCpf('123.456.789-09');
// { ok: true, value: '12345678909' }

formatCpf('12345678909');
// { ok: true, formatted: '123.456.789-09' }

validateCpf('111.111.111-11');
// { ok: false, message: 'CPF with all identical digits is invalid', code: 'KNOWN_INVALID_PATTERN' }

CNPJ — numeric and alphanumeric (new RFB format)

import { validateCnpj, formatCnpj } from '@br-validators/core/cnpj';

// Numeric (current format)
validateCnpj('11.222.333/0001-81');
// { ok: true, value: '11222333000181', format: 'numeric' }

// Alphanumeric (new format — effective July 2026)
validateCnpj('12ABC34501DE35');
// { ok: true, value: '12ABC34501DE35', format: 'alphanumeric' }

formatCnpj('12ABC34501DE35');
// { ok: true, formatted: '12.ABC.345/01DE-35' }

Auto-detect document type

import { detect } from '@br-validators/core';

detect('123.456.789-09');
// { type: 'cpf', ok: true, value: '12345678909' }

detect('ABC1D23');
// { type: 'placa', ok: true, format: 'mercosul' }

detect('110042490114', { uf: 'SP' });
// { type: 'inscricao-estadual', ok: true }

Generate valid documents for tests

import { generate } from '@br-validators/core';

generate('cpf', { seed: 42 });           // reproducible, always valid
generate('cnpj', { format: 'alphanumeric', masked: true });
generate('placa', { format: 'mercosul' });
generate('renavam');
generate('cnh');
generate('inscricao-estadual', { uf: 'SP', seed: 42 });
generate('titulo-eleitor', { uf: 'SC', seed: 42 });
generate('cartao-credito', { brand: 'visa', seed: 42 });
generate('pix', { seed: 42 });           // EVP UUID — Bacen DICT
generate('nfe-chave', { seed: 42 });     // MOC §2.2.6 modulo-11 DV
generate('brcode', { seed: 42 });        // static PIX EMV + CRC16
generate('boleto', { masked: true });    // FEBRABAN cobrança Situação 1
generate('boleto-arrecadacao');          // FEBRABAN Layout v7
generate('inscricao-estadual-produtor-rural', { masked: true }); // SP SINTEGRA Bloco II

generate() is for test fixtures and seed data only — never use in production.
Alphanumeric CPF: generate('cpf', { format: 'alphanumeric' }) throws CPF_ALPHA_SPEC_PENDING until RFB publishes the official algorithm (OFFICIAL-SOURCES.md).

ETL / data cleanup

import { sanitize } from '@br-validators/core';

sanitize(' 123.456.789-09 ', 'cpf');
// { ok: true, value: '12345678909', fixes: ['trimmed', 'removed_non_digits'] }

sanitize('110.042.490.114', 'inscricao-estadual', { uf: 'SP' });
// { ok: true, value: '110042490114', fixes: [...] }

NF-e chave de acesso (44 digits)

import { validateNfeChave, parseNfeChave } from '@br-validators/core/nfe-chave';

const result = validateNfeChave('52060433009911002506550120000007800267301615');
// { ok: true, parsed: { cUF: '52', cnpj: '33009911002506', mod: '55', ... }, uf: 'GO' }

BR Code (PIX QR payload)

import {
  buildStaticPixBrCode,
  parseBrCode,
  validateBrCode,
} from '@br-validators/core/brcode';

// Permanent static QR (no amount — payer sets value at payment time)
const payload = buildStaticPixBrCode({
  pixKey: '[email protected]',
  merchantName: 'Fulano de Tal',
  merchantCity: 'BRASILIA',
});
validateBrCode(payload).ok; // true

// Fixed-value static QR
buildStaticPixBrCode({
  pixKey: '[email protected]',
  merchantName: 'Fulano de Tal',
  merchantCity: 'BRASILIA',
  amount: '10.50',
});

parseBrCode(payload);
// { ok: true, pixKey, pixKeyType, merchantName, merchantCity, amount, txid }

Playground: doc-raiz-playground.vercel.app/pix renders the QR image from buildStaticPixBrCode output. Official sources: Bacen Manual BR Code · Manual de Padrões PIX.

Boleto — cobrança + arrecadação

import { validateBoleto, validateArrecadacao } from '@br-validators/core/boleto';

validateBoleto('03399.02579 08991.834006 71742.301014 6 14500000099668');
// cobrança Situação 1/2 — FEBRABAN FB-0061/2021

validateArrecadacao('846300000003812345678906123456789015234567890129');
// arrecadação 48-digit — FEBRABAN Layout v7

Platform APIs — mask, compare, batch, diff

import { mask, compare, batch, diff } from '@br-validators/core';

mask('12345678909', 'cpf');
// { ok: true, formatted: '123.456.789-09' }

compare('123.456.789-09', '12345678909', 'cpf');
// { equal: true }

batch(['12345678909', 'invalid'], 'cpf');
// { valid: [...], invalid: [...], summary: { total: 2, valid: 1, invalid: 1 } }

diff('12345678909', '12345678901', 'cpf');
// { changed: true, fields: [{ field: 'dv', a: '09', b: '01' }] }

Fiscal code validators (NCM, CFOP, CST)

import { validateNcm } from '@br-validators/core/ncm';
import { validateCfop } from '@br-validators/core/cfop';
import { validateCst } from '@br-validators/core/cst';
import { lookupNcmPorCodigo } from '@br-validators/core/ncm';

validateNcm('01012100');   // { ok: true, value: '01012100', row: { ... } }
validateCfop('1102');      // dotted or plain CONFAZ codes
validateCst('00', { tax: 'icms' });

lookupNcmPorCodigo('01012100'); // LookupResult — ok / not-found / invalid-format

Per-type rules and official sources: docs/OFFICIAL-SOURCES.md · API contract: docs/LIBRARY-API.md

Backend / form integration: format* and mask() validate first — they never left-pad partial input ("0" will not become 000.000.000-00). Do not combine padStart with display formatting in onChange; pad to full width only at submit if your API requires it. Details: LIBRARY-API.md — display vs backend normalization.

Form handler (React / Next.js)

'use client';
import { validateCnpj, formatCnpj } from '@br-validators/core/cnpj';
import { useState } from 'react';

export function CnpjField() {
  const [input, setInput] = useState('');
  const result = input ? validateCnpj(input) : null;
  const formatted = result?.ok ? formatCnpj(result.value) : null;

  return (
    <div>
      <input value={input} onChange={e => setInput(e.target.value)} />
      {formatted?.ok && <p>✅ {formatted.formatted}</p>}
      {result && !result.ok && <p>❌ {result.message}</p>}
    </div>
  );
}

Reference data (offline lookup)

Embedded JSON from official .gov.br sources — no runtime HTTP. Each module exports *_DATA_VERSION with capture date, row counts, and source URLs. Aggregated via @br-validators/core/data-catalog.

Bundle size (gzipped)

Measured @br-validators/[email protected] with pnpm measure:bundle-sizes (esbuild ESM bundle per subpath). Reference-data subpaths include embedded JSON; some validators (e.g. cep, sanitize) also bundle shared core dependencies when imported alone.
