Coverage for Germany

Everything a German address workflow needs

Validation

Deliverable to the house number

Every one of 22.7M records carries a house number — so you validate and correct to the exact Hausnummer, standardize Straße / PLZ / Ort, and flag what changed. Not city-centroid guesses.

Geocoding

Rooftop & entrance coordinates

Each address returns both an access-point and a point coordinate — for routing, catchment analysis and last-mile, not just a postcode pin.

Enrichment · included

Free official codes & demographics

Municipality code (AGS/ARS), Kreis, Bundesland and federal electoral district (Wahlkreis) — plus Zensus 2022 demographics (population, average age, household size, net rent per m², owner-occupier and vacancy rates). Enrichment the enterprise vendors gate behind contracts.

Reference · the German address format

How German addresses are structured

Straße + Hausnr.Friedrichstraße 176 — street name and house number on one line, number after the street.
PLZ + Ort10117 Berlin — a 5-digit Postleitzahl followed by the city/town.
BundeslandOne of 16 states (e.g. Berlin, Bayern, Nordrhein-Westfalen) — derived, not usually written on the envelope.
AGS / ARSThe official municipality key: 8-digit AGS = Land(2)+Regierungsbezirk(1)+Kreis(2)+Gemeinde(3); 12-digit ARS adds the Verband. Returned free.
Straight answers

German address validation, answered

How complete is the German coverage? +
22.7 million house-number-level records across all 16 Bundesländer. Every record carries a house number, so validation and correction resolve to the exact address, not the town or postcode centroid.
What enrichment is included for free? +
Official administrative codes and demographics, at no extra cost. Every street-accurate German validation can return the municipality code (AGS/ARS), Kreis, Bundesland and federal electoral district (Wahlkreis), plus Zensus 2022 demographics (population, average age, household size, net cold rent per m², owner-occupier and vacancy rates). It's built from official German government open data.
Do I get coordinates? +
Yes — both rooftop and access-point. Each validated German address returns latitude/longitude you can use for routing, mapping and catchment analysis, and store for internal use.
Can I store the validated German addresses? +
Yes, for your own internal business use. Unlike the big mapping APIs (30-day-delete or no-repository terms), Acuris lets you keep and reuse validated German results — you just can't resell or redistribute them as a dataset. See the storage-rights comparison →
