Korea Customs Service introduces one-time authentication numbers for overseas direct purchases
2026-07-31 ·TF Media ·Views 21
On 15 August 2026 the Korea Customs Service began issuing a one-time authentication number for each transaction, in order to stop the misuse of Personal Customs Clearance Codes (PCCC).
When an e-commerce operator asks the customs information system to validate a buyer's PCCC, the system issues an authentication number to the importer in real time. If the two numbers do not match exactly at the clearance stage, the import declaration is not accepted. The scheme is being rolled out first to users who have brought their PCCC details up to date.
What it means for the market
A new gate now sits in front of the import declaration itself. Order data from selling platforms arrives carrying both the one-time code and the authentication number, and any mismatch blocks the declaration outright — so catching errors after the fact is no longer fast enough to protect lead times.
HubNet already screens PCCC errors in its own system, collects corrections from customers via KakaoTalk notifications and re-validates them; the one-time authentication number is being folded into that same flow.
