How to verify the validity of a Spanish residence permit online?
Many business or personal processes require the presentation of an identity document: recruitment, rentals, KYC processes, etc.
Nowadays, documents are usually scanned or photographed before being sent by email: therefore, it becomes complex to ensure that these documents are authentic and have not been altered with image editing software such as Photoshop.
Our product addresses this issue and allows you to:
- extract the information from the MRZ strip of identity documents directly online, analyze them, and verify the security keys that guarantee their authenticity
- validate the format of the document number
And all this in just a few seconds!
How does the Spanish residence permit validity verification work?
After confirming your purchase, you will receive an email with the credentials to log into our identity web application (please check your spam folder a few minutes after purchase if you have not received the activation email).
Platform access
You log in to the web application using the credentials received by email after your purchase or registration.
Verification method selection
From your dashboard, select the option “Verify an identity document”.
Document upload
You upload the scan(s) (front/back) of the identity document, either as an image (.jpg, .png) or a PDF.
No additional manipulation (cropping, rotation, etc.) is required: the system automatically detects the orientation and the MRZ area.
Automatic analysis
The service reads the MRZ (Machine Readable Zone) and verifies the security keys.
It checks essential information (card number, date of birth, expiration date, etc.) as well as the document’s integrity via check digits.
Instant results
The analysis results are displayed immediately in the interface as a status (success/failure) and a detailed report (PDF, JSON, or XML).
The report specifies the recognized fields and the validity of each element (check digits, date consistency, etc.).
Report download and archiving
You can download or view the PDF report directly.
Data remains available in the history for later consultation, but you can delete it at any time (privacy guaranteed).
Optional Integration (API)</strong >
If you have a CRM or ERP, you can use the API to automate verification: the document is then sent to the service, and the report (or simply the status) is returned to your internal software.

What is the Spanish residence permit MRZ?
An automatic reading zone, or optical reading zone, is an area on an official document reserved for reading, identifying, and validating this document.
Documents such as passports, national identity cards, residence permits, and driving licenses may or must include, depending on the country and document version, an optical reading zone.
It is located at the bottom of identity documents: it contains all the information present on the document with security keys allowing to verify their authenticity and that they have not been modified.
The information found varies depending on the document type.
How is it composed?
Cards issued since 2021 have three lines of text, each containing alphanumeric characters.
