About

Generates random Pix keys for testing, with the correct UUID format. For testing only, with no link to a real account.

How to generate random Pix keys for testing

The UtilNexo Pix key generator creates fictional Pix keys in valid formats (CPF, email, phone, or random key) to test systems and forms. The generated keys are not registered with any financial institution.

Pix accepts four key types: CPF/CNPJ, email, mobile number, and random key (UUID). The tool generates each of these formats correctly, including the random key in UUID format.

It is important to stress: the generated keys are fictional and belong to no account. They serve to fill test fields, validate format, and simulate payment flows without using real data.

All processing happens locally in the browser. You can choose the key type and generate as many as you need, with or without mask.

Examples

  • Generate random key → 123e4567-e89b-12d3-a456-426614174000 (UUID format).
  • Generate email-type key → "test.generated@example.com".

Limitations

  • The keys are fictional and cannot send or receive Pix; they are not linked to any bank account.
  • The tool validates the format, but does not check whether the key is available or already in use at the Central Bank.

How to use the Pix key generator
