Tools terms of use
The tools at carrapeta.dev/ferramentas are free and meant for testing software, studying and checking documents. By using them you agree to these terms, written here in plain language.
Generated numbers (CPF, CNPJ, PIS)
They are random and only have correct check digits: they exist to test systems. They were not taken from anyone, but they may match the document of a real person or company. Using them to identify yourself, sign up, buy, open an account or in any situation where someone could be deceived is forbidden: it is a crime under Brazilian law (false statement and false identity, articles 299 and 307 of the Penal Code, among others).
Pix and boleto
The Pix generator only builds the copy-and-paste text with the key you typed: nothing is registered with any bank, and the payer sees the key owner's real name in their banking app. The boleto and invoice key readers only check the digit math: they do not guarantee the boleto is legitimate or that the invoice exists. When in doubt, confirm with the issuer.
What you type
Almost everything runs in your browser and is not sent to anyone, me included. The exceptions are the postal code lookup and exchange rates, which go through the site's server without storing what was searched. Details on the Privacy page.
No warranty
The tools are provided as is, with no guarantee that they are always available or error-free. Exchange rates are for information only, not financial advice. Before a tax, financial or legal decision, check the official source (Federal Revenue, SEFAZ, Central Bank, your bank).
Automated use
The site limits the number of requests per network address to stay up for everyone. Mass automated use may be blocked.
