The card-exact version still gets rejected. Now what?
Then the mismatch is upstream, not on the website. Most Korean sites verify you through your mobile carrier's subscriber record, set the day you activated your SIM. Fix it in this order: ① your carrier, at a branded store with your physical ARC (not by phone, not in the app) → ② your bank's KYC record → then retry the site. Full walkthrough in the guide.
The form asks for my passport number, not my ARC.
Then the reference changes: enter your name as in the passport's machine-readable zone (the two lines at the bottom of the ID page). Surname first, one space before given names, ALL CAPS. HONG<<GILSOON<<<< means you type HONG GILSOON.
I don't have a Korean phone number at all.
Phone verification is the default, not the only path. Your routes: a private i-PIN, a Korean-issued card, or in-person service at a branch. The guide covers each, and the SIM guide explains getting a real 010 number.
This tool is the 10-second version.
The full guide covers carrier fixes, i-PIN, bank records and the 2026 facial-verification rollout.
