4Sides tracking FAQ

How do I track a 4Sides package?
Paste the tracking number into the lookup on this page. We read 4Sides'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 4Sides tracking API?
Yes. GET https://api.lastscanned.com/v1/track/FS027259187RU?carrier=4sides returns 4Sides 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 $4.99 a month with 1,000 numbers.
What does a 4Sides tracking number look like?
F + S or E + 9 digits + RU: /^F[SE]\d{9}RU$/. For example FS027259187RU. lastscanned recognizes these formats on its own, so ?carrier=4sides is optional for them.
Does this work for 4Sides and 4sides.ru and Четыре стороны numbers?
Yes. They are tracked through 4Sides and come back as carrier "4sides".
Can an AI agent track 4Sides packages?
Yes. Add lastscanned as an MCP server (https://mcp.lastscanned.com) in Claude, ChatGPT, Cursor or VS Code and ask it where a 4Sides parcel is.
