Swiss Address Validation & Geocoding (geo.admin.ch)
Pricing
from $2.00 / 1,000 address results
Validate, normalise and geocode Swiss addresses with the official swisstopo data: postal code, municipality and BFS number, canton, building identifiers (EGID / EGAID), WGS84 and LV95 coordinates, building facts from the federal register, and reverse geocoding from coordinates.
One entry per lookup: a string ("Avenue de Milan 3, 1007 Lausanne", "8914", "Lausanne", "46.5165, 6.6242") or an object {"id": "...", "address": "..."} / {"postalCode": "1003"} / {"municipality": "Biel"} / {"lat": 46.5165, "lon": 6.6242}. Up to 1,000 per run.
auto detects per query (4 digits = postal code, two decimals = coordinates, otherwise address, falling back to municipality). Force a mode when your input is uniform.
1 returns the best match only. Higher values return alternatives (each candidate is one billable result), useful for ambiguous inputs such as a street without house number or a postal code shared by several localities.
Adds data from the Federal Register of Buildings and Dwellings (RegBL / GWR): construction year, floors, dwellings, category, class, heating and energy source codes, parcel, LV95 coordinates. One extra API call per address.
