Obtaining a certified CURP (Unique Population Registry Code) is an important step for many official procedures in Mexico.
Although many people already have a regular CURP, not everyone understands the differences with a certified CURP or how to obtain one for free.
In this article, we'll explore these differences, the process for obtaining one, and address some common questions.
Differences Between Regular CURP and Certified CURP
The regular CURP and the certified CURP have similar functions, but there are key differences you should know:
- Regular CURP: This is the standard version issued since the system was implemented. Although it is useful for most procedures, it does not always have the official seal or validity that some institutions require.
- Certified CURP: This version includes a digital seal that guarantees that the data has been validated against the Civil Registry. This makes it a more reliable version for procedures such as passports, visas, or access to government programs.
Recommendation: If you plan to carry out important procedures, check if you need a certified CURP to avoid any setbacks.
