How this service works
Dutch address search and geocoding from the official BAG register via PDOK: free-text query (street, number, postcode, town) returns up to 5 matching addresses with postcode, house number, municipality, province and WGS84 coordinates. Use it to validate or geocode a Dutch address for delivery, property or location tasks.
Output
Returns up to 5 matching Dutch addresses from the BAG register, each including the full formatted address, postcode, house number, municipality (gemeente), province (provincie), and WGS84 latitude/longitude coordinates suitable for mapping or geospatial use.
Example use cases
Validate delivery address in Netherlands
“I need to verify that 'Kalverstraat 5, Amsterdam' is a real Dutch address before I ship an order — can you look it up and confirm the postcode and municipality?”
Geocode property location for map
“What are the GPS coordinates for Binnenhof 1 in Den Haag, Netherlands? I need the latitude and longitude to plot it on a map.”
Resolve partial address to full details
“A customer wrote '1234 AB Utrecht' on their form but didn't include a street name — can you search that postcode and see what addresses come up with their full details?”
Technical details
Endpoint
GEThttps://opendata402.com/v1/address/nl?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to validate, geocode, or look up details for Dutch (Netherlands) addresses specifically. It draws from the official BAG register via PDOK, making it authoritative for NL addresses. Prefer this over generic global geocoders when Netherlands accuracy and official data sourcing matter, or when you need the official municipality and province classification alongside coordinates.
Side effects
- Query too short (under 3 characters) or too long (over 120 characters) returns validation error
- No matching addresses found returns empty result set
- Ambiguous query may return irrelevant results — more specific input (postcode + house number) improves accuracy
- Non-Dutch addresses will return no results as the dataset is Netherlands-only
- Misspellings may cause no matches or wrong matches
