How CURP Codes are Constructed

To understand how CURP codes are constructed, one should first understand Hispano-American naming conventions. Full names in Spanish-speaking countries (together with Mexican full names) encompass three parts:

First surname: the father’s first surname; and

Second surname: the mom’s first surname.

The CURP code consists of 18 characters which might be assigned as follows:

The primary surname’s initial and first inside vowel;

The second surname’s preliminary (or the letter “X” if, like some overseas nationals, the person has no second surname);

The first given name’s preliminary;

Date of beginning (2 digits for yr, 2 digits for month, and 2 digits for day);

A one-letter gender indicator (H for male (hombre in Spanish) or M for feminine (mujer in Spanish));

A -letter code for the state where the person was born; for persons born abroad, the code NE (nacido en el extranjero) is used;

The primary surname’s second inside consonant;

The second surname’s second inside consonant;

The primary given name’s second inside consonant; and

Two characters ranging from 1-9 for folks born before 2000 or from A-Z for people born since 2000; these characters are generated by the National Population Registry to stop an identical entries.

For married girls, only maiden names are used.

For instance, the CURP code for a hypothetical particular person named Gloria Hernández García, a female, born on 27 April 1956 within the state of Veracruz, might be HEGG560427MVZRRL05.


A number of exceptions to the above rules exist, including:

“Ñ” – If any step in the above procedure leads to the letter “Ñ” appearing anyplace in the CURP, the “Ñ” is changed by an “X”.

Quite common given names

When a person has given names and the primary given name is Maria, as is usually the case for women in Mexico, or José, within the case of males, the first name will likely be overlooked and the fourth character can be taken from the second given name’s initial. This is because the names María and José are very common and would generate many duplicates if used to generate the code. For example, if the particular person had been named María Fernanda Escamilla Arroyo, her CURP’s first 4 characters can be ESAF because María does not rely for the CURP’s fourth character when a second given name is present.

Catalog of Inappropriate Words

To stop words from forming that will be deemed palabras altisonantes (foul-sounding words, comparable to profanity or pejoratives) in the first 4 characters of the string, a Catalog of Inappropriate Words (Catálogo de Palabras Inconvenientes) lists many such doable mixtures and provides replacements that often entail altering the second letter, a vowel, into an “X”.


Outside Mexico City, the Clave de Registro e Identidad Personal (Personal Registration and Identification Code) is used, in addition to CURP.
