How do I track a First Line package?

Paste the tracking number into the lookup on this page. We read First Line'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 First Line tracking API?

Yes. GET https://api.lastscanned.com/v1/track/1ST06005039050?carrier=firstline returns First Line 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 First Line tracking number look like?

1ST + 11 digits: /^1ST\d{11}$/. For example 1ST06005039050. lastscanned recognizes these formats on its own, so ?carrier=firstline is optional for them.

Does this work for First Line and FirstLine and 1ST and firstline56 numbers?

Yes. They are tracked through First Line and come back as carrier "firstline".

Can an AI agent track First Line packages?

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