The primary international SWIFT/BIC code for the Bank of Korea—the central central banking authority of South Korea—is BOKRKRSTXXX. The initial four letters (BOKR) represent the official bank identifier, followed by the two-letter country code (KR) designating South Korea, the two-character location code (ST) identifying its Seoul headquarters, and the optional three-character branch code (XXX) signaling the primary corporate office. Because the Bank of Korea functions as the central monetary authority rather than a commercial retail bank, this specialized code is utilized primarily for official interbank settlements, sovereign debt operations, and international central banking communications.
