The structure of the CURP reflects Hispano-American naming customs, comprising the initials of given names, father’s surname, mother’s surname, birth date, gender marker, and state of birth. Introduced in 1996, the CURP became a key identifier for Mexicans at home and abroad. Today, it underpins various activities, from tax submissions to passport applications, and remains vital in identification documents. The CURP card\'s modernization allows individuals to print valid copies online, although new CURPs require in-person acquisition.
