This database contains a complete list of registration numbers aka bank codes for banks in Denmark.
The data is created using publicly available information from various sources using webcrawling etc.
And although the database is very accurate, don't expect it to be perfect.
A bank code is a code assigned by a central bank, a bank supervisory body or a Bankers Association in a country to all its licensed member banks or financial institutions. The rules vary to a great extent between the countries.
In Denmark a 4-digit bank code is used (called Registreringsnummer, or Reg. nr.).
