Can I check customs clearance status with just a B/L number?
Calling your carrier or forwarder every time you want a status update takes time. Korea Customs' UNIPASS system officially provides cargo clearance progress (import) and export fulfillment history (export) through an API — all you need is a B/L number or declaration number to check status in real time.
This tool proxies that same UNIPASS API: for imports, it auto-detects a B/L number (MBL/HBL); for exports, it auto-detects a declaration number or B/L number. If multiple cargo control numbers come back, you can pick the exact shipment from the candidate list.
Frequently Asked Questions
Q. Do imports and exports use different lookup methods?
A. Yes. For imports, we first look up cargo control number candidates by B/L number. For exports, a numbers-only input is treated as an export declaration number, while anything with letters (including carrier prefixes) is treated as a B/L number.
Q. Where do I find the cargo control number?
A. Looking up a shipment by B/L number returns a list of associated cargo control number candidates — pick the one you want to check the detailed progress history for.
Q. Is the result updated in real time?
A. This tool queries Korea Customs' UNIPASS data directly, so you see the same clearance progress history as it currently exists in the UNIPASS system.
