When Your Date of Birth is Vital

When people cross borders and claim asylum without reliable identity documents, authorities still have to make fast, important decisions, such as who is this person, what route have they taken, do they pose any risks, and are they an adult or a child?

In theory, these questions are answered through documents and trusted records. In practice, many arrivals have no passport or birth certificate with them, some papers are damaged or not accepted as reliable, and links to records in another country may be slow or impossible. As a result, states lean on other methods: interviews, consistency checks, and biometrics such as fingerprints and photographs to link a person to earlier asylum applications.

Europe’s long-running example is Eurodac, an EU-wide fingerprint database used to identify whether someone has previously applied for asylum or been registered after an irregular border crossing. Even when a person has no documents, fingerprints can connect them to an earlier record and help authorities piece together travel history and prior claims ¹. In these cases, biometrics mainly answer the question ‘have we seen this person before?’. They do not automatically reveal a verified name or date of birth, especially if the person has never been registered in a system that authorities can access.
