Brazilian bank code (COMPE): the 3 digits that identify a bank

The Brazilian bank code is a 3-digit number (the COMPE code) that identifies a financial institution inside the national payment system — 341 Itaú, 001 Banco do Brasil, 237 Bradesco, 104 Caixa, 033 Santander, 260 Nubank. Maintained under the Banco Central / FEBRABAN framework, it's the code printed on boletos, checks and TED/DOC transfers. This tool checks the 3-digit format.

There's a subtle distinction worth knowing: the COMPE code is the classic 3-digit number for paper clearing (checks/boletos), while the ISPB is an 8-digit code that uniquely identifies the institution in the SPB (used by PIX and TED). Most people mean the 3-digit COMPE when they say "bank code".

Well-known codes

• 001 Banco do Brasil · 104 Caixa Econômica Federal · 237 Bradesco.
• 341 Itaú Unibanco · 033 Santander · 399 HSBC (historical).
• 260 Nubank · 077 Inter · 336 C6 · 290 PagBank.
• Leading zeros matter: 001 ≠ 1 — always treat it as a 3-character string.

Where it matters

• Boletos & TED/DOC: the 3-digit code prefixes the account routing.
• Account forms: bank + agência + conta is the canonical Brazilian account triple.
• Reconciliation: matching payments to institutions by COMPE code.
• Mock data / testing: validating the 3-digit field before a bank lookup.

Common pitfalls

• COMPE ≠ ISPB: PIX and the DICT key off the 8-digit ISPB, not the 3-digit COMPE.
• Store as a string: an integer drops the leading zero and corrupts 001, 033, 077.
• Format ≠ exists: any three digits pass the regex; not all 000–999 are assigned banks.
• Fintechs reuse a partner's code: some apps operate under another institution's COMPE.

FAQ

Is the bank code the same as the ISPB? No — the 3-digit COMPE is for clearing (boletos/TED); the 8-digit ISPB uniquely identifies the institution and is used by PIX.

Why does Banco do Brasil show as 001? COMPE codes are three digits with leading zeros; 001 is its assigned code.

Does the code have a check digit? No — it's a 3-digit lookup value, validated by format and the official bank list.
