Dansk Branchekode 2007 (DB07) is very similar to NACE rev. 2. The only difference is the subdivision of some classes, e.g. 64.20.10 indicates that NACE Rev. 2 class 64.20 has been subdivided whereas 38.31.00 indicates that class 38.31 has not been subdivided.
All enterprises have an activity code based on the main activity. You can look up your enterprise on www.cvr.dk.
If the activity code does not reflect the main activity, you should change it by contacting The Danish Commerce and Companies Agency (DCCA), SKAT (the tax department) eller Statistics Denmark
DB07 replaced DB03 January 1, 2008 (DB03 was the Danish nomenclature from January 1, 2003, to January 1, 2008).
