FAQ
What is CURP?
CURP (Clave Única de Registro de Población) is Mexico's universal, 18-character identification number assigned to every citizen and legal foreign resident by RENAPO, the National Population Registry.
Because the code itself carries core biographic data and is reused across nearly every public- and private-sector workflow, CURP is effectively Mexico's "passport" to daily life— think banking, taxes, social security, health services, and even school enrollment.
Why do I need to verify CURP?
Great question! CURP is essential for a variety of reasons:
- Staying compliant: Mexican AML/KYC rules (CNBV/FinCEN-MX) require financial institutions to confirm a customer's CURP against official records.
- Accurate identification: CURP validation prevents typos or forged numbers from polluting customer databases, improving data integrity downstream.
- Government oversight: Agencies rely on CURP checks to track benefits and enforce regulations; businesses that verify CURP align with the same governance standards.
- Fraud prevention: Real-time CURP matching stops identity theft, synthetic-ID creation, and benefit fraud before they impact your platform.
Beyond compliance, CURP unlocks everyday essentials: opening bank accounts, filing taxes (RFC linkage), obtaining IMSS health coverage, applying for credit, and even registering mobile phone lines.
Which data fields does the API return?
The CURP Check API returns the following outputs:
- First name of the individual
- Father's last name
- Mother's last name
- CURP code
- Gender of the individual
- Date of birth (format: YYYY-MM-DD)
- Country of birth
- State of birth within Mexico
- Status of the CURP code
- Year of registration
- State of registration
- Act number associated with the CURP registration
How is CURP verification different from ID checks in other countries?
- Embedded data: CURP digits encode personal attributes up front; many countries' IDs are merely random numbers.
- Universal coverage: CURP is compulsory for citizens and foreign residents—few jurisdictions issue one ID to both groups.
- Cross-system key: CURP ties into nearly every Mexican registry (SAT tax RFC, IMSS health, voting rolls), so one validation unlocks multiple datasets.
- Standardized format: Its fixed 18-character structure makes automated parsing simpler than, say, the variable-length SSNs in the U.S. or Aadhaar's biometric token model in India.
How long does it take to validate a CURP?
Signzy's validation is real-time.
