摘要

Systems and methods for conversion of an entity identifier to a primary account number. A method performed at a server including: receiving as an input an entity identifier formed of: a first set number of digits identifying an issuer institution; a variable number of additional digits identifying the entity at the issuer institution; and a check digit; converting the entity identifier to a primary account number including: ascertaining the issuer institution from the first set of digits; determining a required number of padding digits to increase the number of digits of the entity identifier to a number of digits in a required standard form of a primary account number; and padding the entity identifier with the required number of padding digits in predefined positions in relation to the entity identifier to result in a standard form of primary account number; and carrying out further processing using the padded entity identifier as a primary account number.
