Is the CEP a valid Brazilian postal code?

It uses the NNNNN-NNN eight-digit format with a hyphen, and its first digit matches the postal region of the chosen state — 0 and 1 for São Paulo, 2 for Rio de Janeiro, 8 for Paraná, 9 for Rio Grande do Sul, and so on. It is format-valid but not a guaranteed live delivery code.

How is a Brazilian address structured?

It runs as logradouro type and name with número (and sometimes Apto), then the bairro, then cidade dash UF, then the CEP. The generator follows this multi-line convention.

Do the cidade and CEP region agree?

Yes. Each cidade carries the leading CEP digit for its region, so São Paulo yields a 0xxxx-xxx code, Rio de Janeiro a 2xxxx-xxx code, and Porto Alegre a 9xxxx-xxx code. The remaining digits are random.

Can these be used to actually ship something?

No. They are fabricated for testing only. The combination of street and CEP is randomized and not a real deliverable address. Use them solely in development and QA.

Does anything leave my browser?

No. The whole address is built locally with no network calls, so your generated test data stays on your device.

Fake Address Generator (Brazil)

A fake Brazilian address generator produces correctly formatted addresses for Brazil, following the local convention of logradouro with número, bairro, cidade and UF, and an eight-digit CEP whose first digit identifies the postal region. It is meant for developers and testers exercising Brazilian e-commerce, shipping, and PIX payment flows.

How it works

The generator keeps the region, cidade, and state consistent:

A cidade is chosen, each paired with its two-letter UF state code and the leading CEP digit Correios uses for its region.
A logradouro (Rua, Avenida, Travessa, and so on) and name are picked, with a número and an occasional Apto complement.
A bairro is selected, and the cidade - UF line is formed.
A CEP is built in NNNNN-NNN format: the first digit comes from the region (0/1 São Paulo, 2 Rio de Janeiro, 3 Minas Gerais, 8 Paraná, 9 Rio Grande do Sul), with the remaining digits random.

Tips and notes

The leading CEP digit is region-correct, satisfying the most common regional and length checks; the full code is not tied to a specific street.
An Apto complement appears on many addresses, mirroring real Brazilian apartment addressing.
