The CURP Identity Number, also known as La CURP, is a unique 18-character identification code used to manage your relationship with all government services in Mexico. This alphanumeric string serves as a fundamental identifier for citizens and residents alike.

Who it's for

This identification system is designed for all residents of Mexico. Whether you are a citizen or a resident, having this unique identifier is a requirement for interacting with the national administrative systems.

What you get
