Introduction
In Denmark, Tax Identification Numbers (TINs) are essential for individuals and businesses to comply with tax regulations. These unique identifiers facilitate accurate tax reporting, social security administration, and other governmental interactions. The information provided here is verified from official Danish tax authority websites and trusted government sources.
Tax Identification Number Types
Denmark utilizes two primary types of Tax Identification Numbers:
- Personal Identification Number (CPR-nummer): Assigned to individuals.
- Central Business Register Number (CVR-nummer): Assigned to businesses and legal entities.
The CPR number is used for personal identification, while the CVR number serves as the unique identifier for businesses and organizations.
TIN Format and Structure

For example, a CPR number could be 010203-1234, indicating a birthdate of February 1, 2003, with a male identifier.

TIN Verification and Lookup
Personal Identification Number (CPR-nummer)
While the CPR number’s format can be verified using the EU TIN on Europa portal, personal data verification is restricted to authorized entities to protect individual privacy.
Central Business Register Number (CVR-nummer)
Businesses and individuals can verify CVR numbers through the Central Business Register (CVR) website by searching using the CVR number or company name.
TIN and VAT Number Connection
In Denmark, the CVR number also serves as the VAT (Value Added Tax) number for businesses. When a company registers for VAT, the CVR number is used as the VAT identifier, sometimes prefixed with “DK” (e.g., DK12345678) for international transactions.
Importance of Accurate TIN Validation
Ensuring the accuracy of TINs is crucial for compliance with Danish tax laws. Incorrect TINs can lead to issues in tax filings, business transactions, and may result in legal penalties. Utilizing official verification tools helps maintain accurate records and supports smooth operations both domestically and internationally.
