What is a street name?
A street name is the official name of a road, path or square in Denmark. Street names are set by the municipality and centrally registered in the Datafordeler. Each street has a UUID, a municipality code and a street code (4-digit municipality-local code).
Street names across municipalities
The same street name can appear in several municipalities — for example, around 50 different roads in Denmark are called "Storegade", and "Bjergvej" exists in 117 places. The roads are separate streets with separate street codes, UUIDs and GPS coordinates — they are only identical in name.
To identify one specific stretch you must use either:
- The combination street name + municipality code + street code
vejnavn+kommunekode+vejkode - The street's UUID (
vejnavn_id) - Or indirectly via
vejnavn+postnr
Street code
The street code is a 4-digit code (with leading zeros, e.g. 0023) that is unique within a municipality. It is used by the Building and Housing Register (BBR), the Central Person Register (CPR-Vej) and other public systems.
Status
A street name has a status indicating whether the street is active or discontinued. When a municipality removes a street name (typically due to restructuring) the history is preserved in the registry, but new addresses can no longer be created on the street.
