What does CURP mean and what is it for?

The CURP, which stands for “Clave Única de Registro de Población,” is essentially the national identification code in Mexico. This 18-character identifier helps government authorities, businesses and institutions uniquely identify individuals. It is required for an extensive list of activities, including:

Education: School enrollment from elementary school through university.
Health services: Registration and access to institutions such as IMSS and ISSSTE.
Legal documents: Issuance of passports, voter’s credentials and driver’s licenses.
Employment and tax obligations: Indispensable for labor contracts and tax formalities.
Banking services: Opening bank accounts, credit applications and handling financial transactions.
Government benefits: Enrollment in federal and state support programs.

If you need to generate your CURP for the first time or retrieve it, our CURP generator simplifies the process, allowing you to perform a free online CURP consultation in a matter of seconds.

When and why was the CURP created?

The CURP was officially introduced on October 23, 1996 during the administration of President Ernesto Zedillo. Its creation was part of a national effort to modernize public administration and establish a standardized identification system for all persons in Mexico.

Prior to CURP, managing citizen data across government institutions was a challenge, resulting in inefficiencies, duplication and delays in public services. With the implementation of CURP, Mexico was able to streamline the process of identifying individuals, improving efficiency in public administration and ensuring better access to essential services.

Today, the CURP is a key part of the Mexican government’s digital services, allowing citizens and residents to perform a CURP query and access their data online easily.

How is the CURP structured?

The CURP is composed of 18 alphanumeric characters, and each one contains specific information about the person. Below, we explain how it is generated:

  • First letter and first internal vowel of the paternal surname.
  • First letter of mother’s last name.
  • First letter of the first name.
  • Date of birth in YYMMDD format (e.g., 890615 for June 15, 1989).
  • Gender: H for men, M for women.
  • State of birth code (e.g., JAL for Jalisco).
  • Internal consonants of the paternal and maternal surname and first name.
  • Differentiating digit to avoid duplicates.
  • Verification character, automatically assigned by the system.

For example, the CURP of someone named Juan Perez Rodriguez, born June 15, 1989 in Jalisco, could be: PERJ890615HJALXX.
