TDC NET is a Privately Owned company, a subsidiary of TDC Group, headquartered in Denmark. Founded in 1990, it employs approximately 1,610 individuals. The company provides fibre access as part of its operations within the telecommunications sector.
On June 25, 2026, TDC lost an appeal against a decision by the Danish Competition and Consumer Authority, which had rejected its wholesale access commitments. The telecom complaints board in Denmark ruled that the authority's decision not to market test TDC's wholesale access commitment was a procedural matter, rather than a regulatory one subject to appeal.
