The CURP code is made up of 18 characters or elements, represented by letters and numbers, generated from the data of your document proving your identity (birth certificate, naturalization letter or immigration document). These are:

  • Initial and first internal vowel of the first surname
  • Middle initial
  • First name initial
  • Date of birth (day, month and year) expressed in 6 digits
  • Sex (male or female)
  • Federal entity of birth
  • First internal consonants of the first surname, the second and the first name
  • Homoclave (element to avoid duplicate records)
  • Verifying digit from 0 to 9 for people born until 1999 and a letter from A to Z for those born after 2000.

What is the CURP for?

This code is used to officially identify each person and is considered a key document to access government procedures and services. That is, you must present it to process the voting credential of the National Electoral Institute (INE), register with the Tax Administration Service (SAT), enroll in any school grade, process the passport, access health services, register to vaccination against Covid-19 and even to enter a job and apply for some credit.

How can I get the CURP?

Since the government assigns the Unique Population Registry Code to every individual born or residing in the national territory, practically all Mexicans have it since childhood.

In case you do not have your CURP and you must complete the procedure for the first time, you will have to go to a Civil Registry office. You can check here the location of the CURP module closest to your home.

To obtain it, if you are Mexican or Mexican , you must present the following documentation:

  • Birth certificate.
  • Proof of non-registration of the Unique Population Registration Code.
  • Certificate of Mexican nationality in the event that there is no birth certificate.
  • Naturalization letter.
  • Any of the following valid official identification documents with a photograph: voting credential, identity card, passport, professional card, study certificate, IMSS credential or credential of the Institute of Social Security and Services of State Workers, ISSSTE.

If you are a foreigner residing in Mexico , you must present the following current documentation:

  • Migratory Document, issued by the National Institute of Migration, INM.
  • Diplomatic Visa D1.
  • Official O1 AND O4 Visas.
  • S1 AND S2 Service Visas.

In both cases, all documents must be submitted in original and copy.
