Look up your official CURP

The CURP is an 18-character identifier. For official procedures, retrieve the registered key and certificate through the official portal.

Find your registered key

Open the official CURP lookup service. Use the options provided by the portal to find your record and obtain the available certificate.

Why a calculation is not enough

A formula can construct part of the structure, but it does not confirm registration or the characters assigned by the authority. Use the official certificate when you need proof of your CURP.

If there is an error

Check your documents and request a correction through official channels. CalcularRFC cannot access or change RENAPO records.
