Validate and Generate Pix Keys Online

Validate and generate Pix keys instantly with our free online tool. Pix is the instant payment system created by the Central Bank of Brazil (Banco Central), launched in November 2020, which allows transfers 24/7 in seconds. Each Pix account can register up to five keys that serve as simplified identifiers for receiving payments.

Our validator automatically detects the key type and validates its format. The five supported types are: CPF (11 digits with Modulo 11 check digit verification), CNPJ (14 digits with Modulo 11 check digit verification), Email (RFC 5322 format, max 77 characters as per Pix specification), Phone (+55 country code, valid DDD area code, 8-9 digit number), and EVP (Random Key — UUID version 4 format). The tool accepts formatted input: CPFs with dots and dash, CNPJs with dots, slash and dash, and phones with parentheses or spaces.

The detection algorithm follows a specific order to avoid ambiguity: it first checks for UUID v4 pattern (EVP), then phone prefix (+55), then 11-digit CPF, then 14-digit CNPJ, and finally email (contains @). For CPF and CNPJ, the tool validates the check digits using the official Modulo 11 algorithm from Receita Federal, rejecting numbers with all identical digits.

The EVP key generator uses crypto.getRandomValues() to create cryptographically secure UUID v4 keys following RFC 4122. You can generate from 1 to 50 keys at once, useful for developers testing Pix integrations, QA teams setting up test scenarios, or anyone who needs valid UUID v4 strings. All generated keys can be copied to clipboard with a single click.

Everything runs 100% in your browser — no data is sent to any server. Your Pix keys never leave your device, ensuring complete privacy and LGPD compliance. For related tools, try our CPF Validator or CNPJ Validator.

Frequently Asked Questions

What types of Pix keys exist?
There are five types: CPF (for individuals), CNPJ (for companies), Email, Phone (with +55 country code), and EVP (random key, also called UUID). Each person can register up to 5 keys per account.
What is an EVP key?
EVP (Endereço Virtual de Pagamento) is a random key in UUID v4 format generated by the bank. It is used when you don't want to share personal data (CPF, phone, email) as your Pix identifier.
Does the validation query the Central Bank?
No. This tool only verifies the format and structure of the key (valid CPF, valid email, correct UUID format, etc.). It does not access the DICT (Central Bank key directory) to check if the key is actually registered. To generate a Pix QR Code with your key, use our Pix QR Code Generator.
