For example, the CURP code for a hypothetical person named Gloria Hernández García, a female, born on 27 April 1956 in the state of Veracruz, could be HEGG560427MVZRRL04.
The back contains information referencing the document used as proof to originally assign the CURP code (if it was a birth certificate, folio number and issuing municipio are included), and a barcode.
The first CURP issued in 1996 was generated for the then President of Mexico, Ernesto Zedillo Ponce de León.
CURP number is now used in all Civil Registry individual records (birth and death certificates) and certified copies thereof.
Although primarily intended to substitute for a series of registration numbers (IMSS, RFC, IFE), CURP has failed to replace any of these, which continue to use their own code-generation protocols.
The creation of a Unique Identity Code (CUI) that could possibly replace the CURP has been proposed, to unify the system throughout Mexico.
