Step 1 — Find the green QR sign
Every locker bank has a green sign that says “QR 찍고 보관하세요 · Scan QR code and Store Items”, with the locker group's code (for example TL216B). Scan that QR code with your phone camera.
Step 2 — Choose a size and pay
The page opens in English, Japanese or Chinese. Pick a locker size, then the payment method. There are three options:
- Quick bank transfer — Korean bank accounts only.
- Card payment — Korean cards only. Foreign cards will not work here.
- Overseas payment (해외결제) — choose this. It accepts Visa, Mastercard, Amex, JCB, Diners, Discover and UnionPay, plus Alipay, Alipay+, WeChat Pay, PayPal, GrabPay, Klarna and more.
Step 3 — Enter your email and get your PIN
Enter an email address (or a phone number). A Korean phone number is not required. After payment you receive a one-time PIN.
Step 4 — Open the locker with the PIN
Type the PIN on the keypad of your locker door, put your bag in and close it. Keep your PIN and the payment page — to collect your bag, follow the “How to retrieve” panel on the lockers.
