The CURP (Clave Única de Registro de Población) is Mexico's unique population registry key — an 18-character alphanumeric code that serves as your national identity number. Every person living in Mexico, including foreign residents, needs a CURP for banking, healthcare, taxes, and daily transactions.
Key fact: Your CURP is usually generated automatically when INM processes your temporary or permanent residency card. However, many foreigners don't know their CURP or need help accessing it.
What Is the CURP Used For?
In Mexico, the CURP functions similarly to a Social Security Number in the U.S. or a National Insurance Number in the UK. You'll need it for:
- Opening a bank account — all Mexican banks require a CURP
- Registering with SAT — to get your RFC (tax ID)
- Enrolling in IMSS — Mexico's public health insurance
- Signing contracts — rental agreements, employment contracts, utilities
- Government services — any interaction with Mexican government agencies
- Children's school enrollment — required for both public and private schools
Who Can Get a CURP?
Any foreigner with a valid Mexican residency status can obtain a CURP:
- Temporary residents (Residente Temporal)
- Permanent residents (Residente Permanente)
- Naturalized Mexican citizens
Tourists on FMM visas cannot get a CURP. You must first obtain legal residency in Mexico.
How Foreigners Get a CURP
Option 1: Automatic Generation (Most Common)
When INM processes your temporary or permanent residency card, they register your data with RENAPO (Registro Nacional de Población), which generates your CURP automatically. Your CURP appears on your residency card itself.
Option 2: Online Lookup
If your CURP was already generated, you can look it up and print your official certificate at the RENAPO website. You'll need your full name, date of birth, nationality, and gender.
Option 3: In-Person Registration
If your CURP wasn't generated during your residency process (rare but possible), visit a RENAPO office or Registro Civil with:
- Valid residency card (original and copy)
- Passport (original and copy)
- Birth certificate — apostilled and translated to Spanish by a certified translator
- Proof of address in Mexico (utility bill, bank statement)
Where to Get Your CURP in Riviera Maya
In the Riviera Maya region, you can process your CURP at:
- Cancún: Registro Civil office in the Palacio Municipal
- Playa del Carmen: Registro Civil on Av. Juárez
- Tulum: Registro Civil in the centro
Important: Government offices in Quintana Roo typically operate Monday–Friday, 9:00 AM–3:00 PM. Arrive early as wait times can be long, especially at the beginning and end of each month.
CURP Format Explained
The 18-character CURP encodes your personal data:
- Characters 1–4: First letters of your surname(s) and first name
- Characters 5–10: Date of birth (YYMMDD)
- Character 11: Gender (H = male, M = female)
- Characters 12–13: State of birth (NE = born abroad)
- Characters 14–16: Internal consonants from your name
- Character 17: Disambiguation digit
- Character 18: Check digit
For foreigners born outside Mexico, characters 12–13 are always "NE" (Nacido en el Extranjero).
Common Problems & Solutions
CURP Not Found Online
If the RENAPO website doesn't find your CURP, it may be that INM hasn't transmitted your data yet. Wait 2–4 weeks after receiving your residency card, then try again. If it still doesn't appear, visit a Registro Civil office in person.
Name Discrepancies
Ensure your name is spelled exactly the same on your residency card and your CURP. Accents, middle names, and special characters (ñ, ü) can cause mismatches. Any corrections must be made at RENAPO.
Duplicate CURPs
If you changed residency status (e.g., from temporary to permanent) and received a new residency card, you may accidentally get a second CURP. Contact RENAPO to merge and cancel the duplicate.
Frequently Asked Questions
Can foreigners get a CURP in Mexico?

How long does it take to get a CURP?
If your CURP was generated during your residency process, you can look it up and print it instantly online. If you need to register for the first time at a RENAPO office, it typically takes 1–3 business days.
