# Correos (Spain) Tracking API & MCP

URL: https://docs.lastscanned.com/carriers/correos

Query live **Correos** (`correos`, Spain's national post) package status and scan history in a single synchronous `GET` request or MCP tool call. `lastscanned` auto-detects UPU S10 numbers ending `ES`; Correos' own `PQ` parcel codes are tried when nothing else claims them.

## Overview & Quick Facts

## Notes

- Scan wording is Spanish, as Correos prints it. Times are Spanish local time, shown as `localTime` only because Spain spans two time zones.
- A number Correos has no record of comes back as `not_found`.
