Check the structure of TIN codes

Launch the interactive TIN on Europa Online Check Module to confirm whether the structure of the Taxpayer Identification Number that you enter is valid. Although you can use the module for checking the code structures you cannot receive positive confirmation as to whether it actually exists or has been allocated to a taxpayer in the country concerned. The Website and the Module work in 22 different languages and provide general information on TINs and taxpayer identification in EU countries.
