Tracking — entry 002 of 10
Correios
Correios exposes a REST API suite covering package tracking (Rastro), address lookup (Busca CEP), shipping cost (Preço), and delivery-time estimates (Prazo) for Brazil's national postal service. Access is gated behind a commercial shipping contract rather than public self-serve signup, with keys issued and validated through the CWS (Correios Web Services) portal under a Meu Correios login. A 2026 security tightening now restricts tracking queries to parcels tied to the querying contract, closing off third-party lookups of packages a caller didn't send.
