When shopping overseas, you'll often see the message "Please enter your personal customs clearance number." This is because, instead of using your resident registration number as before, the process of verifying the consignee using the personal customs clearance number issued by the Korea Customs Service's Uni-Pass has become commonplace.

This app provides a single page with key information about the personal customs clearance number, frequently asked questions, and direct links to the official Uni-Pass website, making it easy for even first-time overseas shoppers to follow.

Issuance/inquiry can be done through Uni-Pass using mobile phone authentication, joint/financial certificates, or simple authentication. Typos when entering the number may delay customs clearance, so we recommend copying and pasting.
