290 services online, more than any other German state, and still only about half the 575 in the national catalogue. Top of Bitkom's administration category in 2024, third by 2026.

Hamburg piloted Germany's first online residence re-registration in September 2022, built with the federal interior ministry for reuse by every state under the 'One for All' principle. By early 2025 Hamburg offered 290 online services, more than any other state, aided by its city-state structure, but roughly half the 575-service national OZG catalogue and years past deadline.
📊 Impact
290 administrative services online in early 2025, the most of any German state (Bavaria: 276), against a national picture of only 196 of 575 OZG services available countrywide. The electronic residence registration launched 20 September 2022 for unmarried residents without minor children moving within Hamburg, about 57% of all moves in the city, covering a potential ~250,000 registrations per year; it became the first OZG service rolled out in all 16 states.
🎓 Lesson
Being first is not the same as being finished. Hamburg genuinely shipped the service other states later reused, and it topped Bitkom's administration category in 2024 — but by the 2026 edition it had slipped to third behind Hessen and Bayern, and its own advantage is structural: a city-state has one administration to coordinate, which a Flächenland cannot copy.
