Tax identification numbers (TINs) - Organisation for Economic Co-operation and Development

Tax identification numbers

This section provides an overview of domestic rules in the jurisdictions listed below governing the issuance, structure, use and validity of Tax Identification Numbers ("TIN") or their functional equivalents. The jurisdiction-specific information the TINs is split into a section for individuals and a section for entities and can be accessed by clicking on the name of the jurisdiction below. Each jurisdiction has provided the OECD Secretariat with input on its current rules in relation to the issuance, structure, use and validity of its TINs. While the jurisdictions and the OECD endeavour to keep the information as accurate and up to date as possible, the information in this section is to be considered as preliminary guidance only. If further questions in relation to a TIN arise, it is recommended that the tax administration of the relevant jurisdiction be contacted directly.
