Banking and mobile identity verification are closely connected in Korea. A working local phone number, residence documentation, and consistent name spelling can determine whether an account or app works smoothly.
Requirements vary by bank, branch, nationality, residence status, and transaction purpose. Common documents include a passport, residence card, Korean phone number, local address, and proof of work, study, or the reason for the account.
Choose one exact English-name format and use it consistently where possible. Spaces, hyphens, order, and truncated names can cause verification failures between immigration, the phone carrier, and the bank.
Ask which services are available immediately: debit card, online banking, mobile app, overseas transfer, automatic payment, cash withdrawal limits, and English support. Some accounts begin with transaction limits until additional proof is provided.
Never share a one-time password, security card number, full PIN, or remote-control access because a caller claims to be a bank or government agency. End the call and contact the institution through its official number.
Keep a backup payment method during the setup period. A foreign card may not work everywhere, and a new Korean account may not yet support every online purchase.
The Financial Supervisory Service publishes a foreign-resident financial guide, while individual banks publish their own current document lists. Check both before making a special trip to a branch.
