ID – Check Spanish passport validity online

How to verify the validity of a Spanish passport online ?

Many business or personal processes require presenting proof of identity: recruitment, rentals, KYC processes, etc.

Nowadays, documents are usually scanned or photographed before being sent by email; therefore, it becomes complex to ensure these documents are authentic and have not been modified with image editing software like Photoshop. Our product addresses this issue and allows you to:

• extract information from the MRZ (Machine Readable Zone) of identity documents directly online, analyze them, and verify the security keys to ensure their authenticity
• validate the format of the document number

All of this in just a few seconds!

How does the Spanish passport validity verification 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).

• Access to the platform

  • You log into the web application using the credentials sent by email after your purchase or registration.

• Selection of verification mode

  • From your dashboard, you choose the option “Verify an identity document.”

• Document upload

  • You upload one or more scans (front/back) of the identity document, as images (.jpg, .png) or PDFs.

  • No further manipulation (cropping, rotation, etc.) is required: the system automatically detects the orientation and the MRZ zone.

• 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 result

  • The analysis results appear immediately in the interface as a status (pass/fail) and a detailed report (PDF, JSON, or XML).

  • The report specifies the recognized fields and the validity of each element (control keys, date consistency, etc.).

• Download and archiving of reports

  • You can download or view the PDF report directly.

  • Data remains available in the history for later consultation, but you have the option to delete it at any time (confidentiality guarantee).

• Optional integration (API)

  • If you have a CRM or ERP, you can use the API to automate the verification: the document is sent to the service, and the report (or simply the status) is returned to your internal software.

  • You can find all details on these links:
    • Identity API
    • Resources API

• Account and credits management

  • Your analyses are only charged when the MRZ detection is successful (i.e., when information has been properly extracted).

  • You can check your credit balance at any time and, if needed, subscribe to a plan suited to your needs.

• Support and assistance

  • In case of difficulty or questions, you can contact support via email or through the integrated help interface.

  • Additional resources (guides, FAQs, API documentation) are also available online.

You can find all the details on the product page Identity web suite.

Which elements are validated during Spanish passport validity verification?

Spanish passport document number

The document number follows an official pattern from the ministry (3 letters followed by 6 digits): we verify it to validate the number.

MRZ information

Use cases

• Recruitment and onboarding
  When you need to validate a candidate’s identity before signing a work contract, online verification of an identity document guarantees document compliance and limits fraud risks. You save time on administrative tasks and provide a smoother experience for your future employees.

• Real estate rental
  When signing a lease, you can require verification of identity documents to validate the tenant’s reliability. This step ensures that the provided document is authentic and that information (name, birth date, etc.) has not been modified or forged.

• KYC Process (Know Your Customer)
  In the banking, financial sector, or for service providers subject to anti-money laundering and fraud prevention obligations, identity validation is essential. MRZ reading and security key verification allow compliance with current regulations while simplifying checks.

• Registration for an online service
  Whether for access to a gambling platform, online trading, or any other service requiring proof of majority or strong authentication, automatic identity document control quickly verifies that the user meets the legal requirements.

• B2B relationships or partnerships
  In certain partnerships or commercial contracts, an identity document may be required to confirm the identity of a partner or legal representative. Automated identity document verification helps secure transactions and builds trust between parties.

What is the Spanish passport MRZ?

An automatic reading zone, or optical reading zone, is an area on an official document reserved for reading, identification, and validation of that document.

Documents such as passports, national identity cards, residence permits, and driver’s licenses may or must include, depending on the country and document version, an optical reading zone.

It is located in the lower part of identity documents: it contains all information present on the document with security keys to verify their authenticity and that they have not been altered.

The information varies depending on the document type.
