CEP 90000-000 – Porto Alegre, Rio Grande do Sul

CEP 90000-000 for Porto Alegre, Rio Grande do Sul is part of the Brazil postal code system, which uses a numeric code of 8 digits (e.g. 01310-100). Addresses here are organised as State → Municipality → District / Locality.

Administratively it is recorded in Rio Grande do Sul within Brazil. Postal codes are assigned by delivery route rather than by administrative boundary, so a single code can cover more than one locality and a locality can fall under several codes.

No building-level records are held for this code in the imported dataset, so only the code and its location details are shown. The absence of records does not mean the cep is unused.

Couriers, e-commerce checkout forms and address autocomplete tools all rely on the cep to route mail and to check that a stated address matches the code. Because a cep identifies a delivery area rather than a single building, two addresses that share the same code can still be some distance apart.

Always write Brazil CEP in full when completing a form, including any leading zero. Enter a valid Brazilian CEP, e.g. 01310-100. Data source: a third-party open dataset. This is a reference snapshot, not a live government feed, so confirm the code with the sender, carrier or postal authority before relying on it.
