How to choose
- Already have the CURP? Use lookup to confirm the CURP with RENAPO and retrieve the registered identity.
- Don't have the CURP? Use search with the person's names, birth date, sex, and state of birth. It returns the CURP RENAPO has registered for them.
- Also have an RFC? The same API key validates it against SAT with the RFC endpoints on rfccheck.com.
