Paste the tracking number into the lookup on this page. We read Yanwen'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.

Yes. GET https://api.lastscanned.com/v1/track/:number?carrier=yanwen returns Yanwen 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.

Postal (S10): 2 letters + 9 digits + YP; Yanwen: YW + 3 letters + 12 digits. For example YWUSA123456789012. lastscanned recognizes these formats on its own, so ?carrier=yanwen is optional for them.

Can an AI agent track Yanwen packages?
Yes. Add lastscanned as an MCP server (https://mcp.lastscanned.com) in Claude, ChatGPT, Cursor or VS Code and ask it where a Yanwen parcel is.

Other carriers

Tracking pages are for people. This is for your code.

Every carrier shows a parcel differently. lastscanned reads them all and answers in one shape, so your app, your spreadsheet or your agent handles any carrier the same way.
