How to verify the validity of a German identity card online?

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

Nowadays, documents are generally scanned or photographed before being sent by email: therefore, it becomes complex to ensure that these documents are authentic and have not been altered using image editing software such as Photoshop.

Our product addresses this issue and allows:

  • extracting information from the MRZ band of identity documents directly online, analyzing them, and verifying the security keys that ensure their authenticity
  • validating the document number format (Dokumentennummer)

All this in just a few seconds!

What elements are checked during the validity verification of the German identity card?

The document number of the German identity card (die Dokumentennummer in deutschen Ausweisen)

The document number corresponds to an official pattern from the ministry: we verify that this is indeed the case to validate it.

  • Document upload
    • You upload the scan(s) (front/back) of the identity document, as image (.jpg, .png) or PDF files.
    • 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 integrity of the document via the check digits.
  • Instant result
    • The analysis results are displayed immediately in the interface as a status (pass/fail) and a detailed report (PDF, JSON or XML).

    • You can download or view the PDF report directly.
    • The data remains available in the history for later consultation, but you have the option to delete it at any time (privacy guarantee).
  • Optional integration (API)
    • If you have a CRM or ERP, you can use the API to automate verification: the document is sent to the service and the report (or simply the status) is returned to your internal software.

  • Real Estate Rental

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

What document formats are accepted?

You can send your documents as jpg / jpeg / png images or as PDFs.

Am I charged if information is not extracted correctly during the German identity card validity verification?

The answer is no! Only a correctly recognized document is billable!

If characters are not correctly detected (which may happen with a poor quality photo, for example), you have the option to correct them to ensure reliable analysis no matter what.

What is the MRZ band of the German identity card (Machine Readable Zone)?

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

Thus, documents such as passports, national identity cards, residence permits, and driver’s licenses may or must contain, depending on countries and document versions, 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 that verify their authenticity and that they have not been altered.

The information contained varies depending on the document type.

How is it structured?

Cards issued from 2021 have three lines of text, each containing alphanumeric characters.
