What Is a Boleto, and What Happens If It Expires

Rent, school fees, insurance, a cartório charge, a shop that will not take your foreign card: sooner or later someone asks you to pay one.

Three species, and one of them is optional

Since February 3, 2025 the rule is Resolução BCB nº 443, which revoked the 2012 circular behind it. A boleto presents one of three things: a debt being collected, an offer you accept by paying, or a deposit into your own account.

The middle one is the trap. A boleto de proposta is not a bill: paying is optional, not paying causes no protest and no credit listing, and its due date is o termo final do prazo para sua aceitação — the deadline to accept, not to pay. A real bill is a boleto de cobrança.

What the barcode actually carries

Forty-four digits, in the interleaved 2 of 5 symbology: three for the bank's clearing code, one for the currency, one check digit, four for the due date, ten for the amount, twenty-five the bank defines itself.

Those four digits are not a date. They are a day count from a base fixed at October 7, 1997: factor 1000 meant July 3, 2000, plus one a day. It ran out — 9999 fell on February 21, 2025, and the next day it rolled back to 1000.

Then the rule that settles arguments. Banco do Brasil's specification says the factor "prevalece sobre a informação" printed in the due-date field: the code outranks the paper. And the convention puts the central register above both.

Why the due date usually does not stop the payment

Until 2018 an overdue boleto could only be paid at the issuing bank. That ended on November 10, 2018, the last phase of the Nova Plataforma de Cobrança. Announcing it two days earlier, FEBRABAN said overdue boletos could then be paid "em qualquer banco ou correspondente" — at any bank or agent. The convention behind the arrangement says the same.

The register makes that work: it must hold the data to update the amount owed before or after the due date, and the boleto must print the terms for settling late.

You may not be late at all. Law 7,089 of 1983 bars banks from charging default interest on a title falling due on a Saturday, Sunday or holiday, if it is settled no primeiro dia subsequente — the next day, and the law does not say business day. The convention reads that same law and goes further: its article 22 lets the slip be received on the first business day after the due date, with no interest and no fine, and at another institution. Brazil has more holidays than your calendar shows.

What the extra money is, and where it stops

Where the debt is consumer credit or financing, the Consumer Code caps the late fine: it may not exceed "dois por cento do valor da prestação", two per cent of the instalment. Interest is contractual, printed on the document.

Past that comes protest, which is not a bank action at all. Law 9,492/1997 defines it as the formal notarial act by which default is proved: the creditor presents the title, the notary sends an intimação, and the protest is registered within three working days of the protocol. Paying at the notary's office inside that window stops it; afterwards, cancellation must be requested there.

What actually kills a boleto

Not the law — a field. In the FEBRABAN file a beneficiary sends its bank, every boleto carries days-to-protest and days-to-write-off, both counted from the due date; past the second, the title goes back to the beneficiary. One bank's layout caps it at 99 days. Neither is part of what the boleto must print.

So a refused boleto is rarely expired by law: it was written off, or never registered — and an unregistered slip falls outside the convention, payable only at the issuer's own channels. Either way, ask for a segunda via, reissued with the amount updated.

Locals reach for PIX instead, which tourists can sometimes use. A boleto wants a CPF somewhere, for the cashier's reason, and argues for a Brazilian account. A refused card is often why you got one; a rental guarantee is only wrapped in one; and cash will not help at R$ 10,000 or above.

What we could not verify

• How long an expired boleto stays payable. No published rule fixes it: the window is a field the beneficiary fills in at registration, and it is not among the information the boleto must carry.
• Whether a convention updated for the 2024 resolution exists. The text FEBRABAN publishes is dated February 5, 2021 and still cites the circular revoked in 2025. The banks had 150 days to submit changes; no replacement was published as of September 24, 2026.
• The formal status of the 2000 barcode act. The Central Bank's page lists no norm revoking it, but states no status either.
