Full Definition
The matrícula consular de alta seguridad (high-security consular registration card) is an identification document issued by the Mexican government to Mexican nationals living outside Mexico. Other Latin American countries have similar consular IDs.
The card includes the holder's name, photo, current foreign address, date of birth, signature, and a unique identification number. Modern versions include security features comparable to U.S. state IDs.
In the U.S., matrícula consular is increasingly accepted as identification by banks, utilities, and apartment communities — especially those serving Latino communities. It's often paired with a passport for full verification.
