How to verify the authenticity of a Spanish residence permit online?
Many business or personal processes require presentation of identity proof: recruitment, rentals, KYC processes, etc.
Nowadays, documents are generally scanned or photographed before being sent by email; it becomes difficult to ensure these documents are authentic and have not been altered using image editing software like Photoshop. Our product addresses this issue by allowing you to:
- extract information from the MRZ band of identity documents directly online, analyze it, and verify security keys to ensure authenticity
- validate the format of the document number
And all this in just a few seconds!
What elements are validated during the Spanish residence permit validity check?
The Spanish residence permit document number
The document number corresponds to an official pattern from the ministry: we verify it matches this pattern to validate it.
The personal number of the ID card holder (NIE)
The personal number (NIE) consists of 8 characters followed by a security key and corresponds to an official pattern from the ministry: we verify that the whole is valid.
MRZ information
We check and validate all MRZ information as well as security keys.
How does the Spanish residence permit validity check work?
After your purchase is validated, you will receive an email with credentials to log into our identity web application (please check your spam folder a few minutes after purchase if you do not receive the activation email).

What is the Spanish residence permit MRZ band?
An automatic reading zone, or optical reading zone, is an area on an official document reserved for reading, identification, and validation of the document.
Documents such as passports, national identity cards, residence permits, and driving licenses may or must include, depending on the country and document versions, an optical reading zone.
It is located in the lower part of identity documents: it contains all the information present on the document with security keys allowing verification of their authenticity and that they have not been altered.
The information found varies depending on the type of document.
How is it structured?
Cards issued from 2021 have three lines of text, each containing alphanumeric characters.
