Busca Postal is an online service for finding Brazilian postal codes (CEPs) and matching postal addresses. Its search tool lets users enter a street or other address, then refine results by city and state, with listings organized across all Brazilian states. The service is designed to make it easier to identify the correct CEP for mailing and deliveries, and describes its information as regularly updated, drawing on reference data from Brazil’s postal service, Correios (ECT).

The website also explains how the eight-digit CEP system works, including how its digits correspond to postal regions and how the final three digits identify a street or specific section. Visitors can learn why some smaller municipalities use a single code and browse popular city searches, including São Paulo, Rio de Janeiro, Belo Horizonte, Cuiabá, and Porto Alegre. Busca Postal presents its service in Brazilian Portuguese and also offers a Portugal Portuguese language option. Its site includes information about the organization, privacy, terms of use, and contact details, alongside tools and guidance for looking up postal codes throughout Brazil.
