12.ABC.345/01DE-35 → ✓ CNPJ (alphanumeric)

التفاصيل والقيود

CPF and CNPJ end with two check digits calculated with mod 11. From July 2026 new CNPJs can contain letters in the first 12 positions; each character counts as its ASCII code minus 48, so numeric CNPJs keep validating as before (IN RFB 2.229/2024).

Sequences such as 111.111.111-11 pass the arithmetic but are invalid and are rejected.

FAQ

Does a valid CPF mean it belongs to someone?

No. The check digits only catch typing errors. Use the Receita Federal services to check registration status.

What is the alphanumeric CNPJ?

A new CNPJ format with letters and digits in the first 12 positions, issued from July 2026. Existing numeric CNPJs stay valid.

Can I use the generated numbers?

Only as test data in software development. They are random and must not be used to identify people or companies.
