Clave Única de Registro de Población (CURP): Who Qualifies and What You Get
Learn how to obtain your CURP, the essential 18-character identification code required for all government services in Mexico.
The Clave Única de Registro de Población (CURP) is a unique 18-character identification code used to identify individuals for all government services.
Who it's for
This identification is required for all Mexican citizens and residents. Whether you are a citizen or a resident living in the country, this code serves as your primary link to national administrative systems.
What you get
By obtaining this code, you receive a standardized 18-character identifier. This specific alphanumeric string is used across various sectors to ensure that your personal data is correctly recognized when you access any government services. It acts as a foundational piece of your official identity for administrative purposes.
What it costs you
There is no cost to obtain or use this identifier. The process is free for all applicants. If you already have a code assigned to you, you can simply use the online system to find it and print the document yourself at no charge.
The catch to know
The most important thing to verify is that your name and your date of birth match your birth certificate exactly. Because this code is used to link your information across many different systems, any small typo or variation from your official birth certificate will cause errors. If the data does not match your legal documents, you will likely face difficulties when trying to use the CURP for other official tasks.
