Paste the tracking number into the lookup on this page. We read Serpost's own tracking data and show every scan, the current status and the delivery details. Anyone can do one lookup a day without signing up.

Is there a Serpost tracking API?

Yes. GET https://api.lastscanned.com/v1/track/:number?carrier=serpost returns Serpost tracking as JSON, in the same shape as every other carrier lastscanned covers. Sign up for a free key with 5 lookups a day, or Pro for $4.99 a month with 1,000 numbers.

What does a Serpost tracking number look like?

Tracking number: auto-detected. For example RE123456785PE. lastscanned recognizes these formats on its own, so ?carrier=serpost is optional for them.

Can an AI agent track Serpost packages?

Yes. Add lastscanned as an MCP server (https://mcp.lastscanned.com) in Claude, ChatGPT, Cursor or VS Code and ask it where a Serpost parcel is.
