How many digits does a Korean bank account have?

Written by Editorial Team | Last Updated: August 2026

Bank account numbers in South Korea typically range between 10 and 14 digits in total length, though the exact digit count varies depending on the specific financial institution, account type, and branch structure. Unlike standardized international account formats, each domestic bank maintains its own proprietary numbering scheme. When executing international wire transfers, users must ensure the entire account string and the corresponding three-digit bank code are entered with absolute accuracy to prevent transaction failures.
