Tracking · head-to-head
Aftership vs Correios
AfterShip's Tracking API aggregates delivery status from couriers worldwide behind a single as-api-key header, letting merchants create trackings, poll shipment checkpoints, and register webhooks instead of integrating each carrier separately. A free plan covers low-volume testing, with metered paid tiers billed as tracked-shipment volume grows.
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.
