DAWA shuts down 1 October 2026.
What now?

DAWA — dawa.aws.dk — has been the backbone of Danish address integrations since 2013. It shuts down permanently on 1 October 2026 at 10:00 Danish time. 20 days left.

Why is DAWA shutting down?

DAWA was only ever a stopgap — stood up to distribute address data before Datafordeleren existed — so its functionality is being consolidated back into Datafordeleren. Official source: the Klimadatastyrelsen notice: "DAWA lukker i sin helhed den 1. oktober 2026."

For developers this means: every integration that hits dawa.aws.dk stops working on 1 October 2026. Datafordeleren has a completely different API form (GraphQL, OAuth2, enterprise agreement) — you can't just flip the base URL.

Two dates before that already bite: Matriklen, GeoDanmark and DAGI stopped being refreshed on DAWA on 30 June 2026, and Danske Stednavne has not been updated since September 2025 — those endpoints still answer, but the data is frozen.

Worth knowing why the date moved: KDS states plainly that the shutdown slipped to after the summer holidays because Adressevælgeren itself was delayed. The replacement set the timetable — not the other way round. That is the honest reason not to plan around a third date.

What already died — before the shutdown

DAWA has been shedding data for two years. If any of this is still in your code, it is already returning nothing or returning stale values:

Data	Gone since	Note
BBR	3.4.2024	Last data update was 16.12.2023 — stale for months before removal.
Zones	11.9.2024	Zone data had not been updated since March 2022.
Bulk-recipient postcodes	28.2.2025	Retired by Trafikstyrelsen 1.1.2025. Searches using one now find nothing — use the authoritative postcode.
WMS	14.1.2025	Only vejpunktlinjer are still served, temporarily.

If you use /replikering, read this

DAWA's replication is an event stream: you poll /replikering/haendelser with a sequence number and get every change since. Datafordeleren's answer to it is entity-based file download — full files, refreshed daily. If your mirror needs change events, or needs to be fresher than once a day, that is not a migration, it is a redesign. Our /replikering keeps the sequence-number event model.

Timeline to the shutdown

Date	What happens
September 2025	Danske Stednavne stops being updated on DAWA. The endpoint still answers — the data is frozen.
30 June 2026	Matriklen, GeoDanmark and DAGI are no longer kept current on DAWA, due to changes on Datafordeleren.
Now	DAWA still answers on every endpoint. This is the window to migrate calmly — parallel-test against us with zero risk.
1 October 2026	kl. 10:00 — DAWA closes in its entirety. Every service in the DAWA docs, plus the existing address WFS services, stops responding.
1 October 2026 — onwards	Datafordeleren (GraphQL/OAuth2) and KDS's Adressevælger are the official routes. Or us — unchanged REST.

What to do today — 3 minutes

1. Get a free key: danadresse.dk/dashboard/signup (2,000 calls/month, no credit card).
2. Change the base URL in your code: dawa.aws.dk → api.danadresse.dk.
3. Add a header: X-Api-Key: dawa_live_….

That's it. No other code changes — we mirror DAWA's JSON shape 1:1.

# Before (DAWA)
curl 'https://dawa.aws.dk/autocomplete?q=Rådhuspladsen'

# After (Danadresse) — same response
curl 'https://api.danadresse.dk/autocomplete?q=Rådhuspladsen' \
     -H 'X-Api-Key: dawa_live_…'

FAQ — DAWA shutdown

Do I lose my address IDs?

No. We use the same UUIDs as DAR (the Climate Data Agency's authoritative register). DAWA's id === our id. No database migration on your side.

What about the /replikering endpoint?

Our replication stream is native and live — event-based sync with senesteSekvensnummer, just like DAWA.

Can I test BEFORE I flip production?

Yes. We have both dawa_test_* keys (sandbox mode) and a migration CLI: npx @danadresse/migrate-cli scan ./src which scans your codebase for DAWA references.

Is Danadresse cheaper than DAWA?

DAWA is free because it's state-funded. We're free up to 2,000 calls/month with a free key. After that 89 DKK/mo for 300k calls — cheaper than the alternatives.

What if the Climate Data Agency changes its mind?

It already moved once — the shutdown was postponed from 1 July to 1 October 2026. Don't count on another reprieve: migrating now costs one line of code. Official source: the Klimadatastyrelsen notice ("DAWA lukker i sin helhed den 1. oktober 2026"). And even if it's pushed again — our API keeps running.

Is it legal?

Address data is public (CC BY 4.0 from the Climate Data Agency). We have the same licensing basis DAWA had.
