'My whole identity got erased': Berlin residents speak out as duplicate image crisis hits housing and ID systems

At least several hundred Berlin residents have been left unable to renew tenancy contracts, access city services, or verify their identity online after duplicate image files embedded in municipal and private databases triggered automated rejection flags across multiple platforms this spring. The problem — which data advocates have traced to a flawed 2024 migration of the city's Bürgeramt registration system — has fallen hardest on residents in Neukölln and Wedding, where community advice centres report a sharp rise in walk-in queries since April.

The timing could not be worse. Berlin's Senatsverwaltung für Inneres has been pushing residents to complete digital identity verification through its BerlinPass portal ahead of a July 31 deadline tied to updated federal residency documentation rules. For anyone whose photo record was duplicated in the system migration, that portal simply returns an error. With Bürgeramt appointment slots booked out six to eight weeks in advance across most of the city, the practical fix — showing up in person — is easier said than done.

Communities bearing the brunt

The duplicate image problem has surfaced with particular force in parts of the city where residents already navigate multiple bureaucratic systems. Neukölln's Rollbergstraße is home to Kotti & Co, the long-running housing rights group, and caseworkers there say they have encountered the issue repeatedly in recent months when helping residents contest rent increases or file housing subsidy applications — processes that now require digital identity verification. Wedding's Beratungszentrum Migration, on Müllerstraße, reported similar patterns from its caseload.

Turkish-German families and recently naturalised residents appear disproportionately affected, according to community workers at both centres, because their records were among the first batch processed in the 2024 system migration. Several residents described the experience of being told their own face was flagged as a duplicate — effectively that the system did not believe they were who they said they were. One woman, a long-term resident of Hermannplatz who declined to give her name, described waiting three months for a corrected file while her landlord withheld renewal paperwork. Another resident, a freelance graphic designer based near Tempelhof, said the frozen verification status had blocked him from two separate clients who required a verified BerlinPass login for contract signing.

The SPD-led Senat has acknowledged the migration error in internal correspondence — documents reviewed by The Daily Berlin — but has not yet made a public statement quantifying the scale of the problem. A spokesperson for the Senatsverwaltung für Inneres did not respond to questions submitted on July 3. Independent estimates from the Digitale Gesellschaft e.V., a Berlin-based digital rights organisation, suggest the flawed migration could have affected between 3,000 and 5,000 records, though the group notes its figure is based on reports aggregated from advice centres and is not an official count.

What residents can do now

BVG commuters and others dependent on digitally verified travel concession cards — including the 29-euro Sozialticket — should check their BerlinPass status before the July 31 deadline, since a duplicate image flag can silently void a verified account without generating a notification email. The Verbraucherzentrale Berlin, based on Hardenbergplatz, has published a step-by-step guide on its website for filing a formal Auskunftsersuchen — a data access request — that forces the relevant Bürgeramt to produce the specific file entry causing the conflict. That request, submitted in writing, triggers a 30-day statutory response window under the DSGVO, Germany's application of the EU's General Data Protection Regulation.

For residents whose tenancy renewals are being held up, Mieterverein Berlin, which operates advice offices across the city including on Spichernstraße in Wilmersdorf, has confirmed it is taking on cases where a landlord has cited failed digital verification as grounds to delay a contract. The organisation advises affected tenants to document every step and to request written confirmation from their Bürgeramt that a correction request is pending — that document can be presented to landlords as evidence the delay is not the tenant's fault.

The Senat has said it expects to complete a phased re-migration of affected records by the end of August. For the residents already three months into waiting, that timeline offers cold comfort.
