Introduction
In Latvia, the Tax Identification Number (TIN) is a unique identifier assigned to individuals and entities for tax purposes. For individuals, this is known as the Personal Identity Number (Personas kods), while for entities, it is referred to as the Enterprise Registration Number (Uzņēmuma reģistrācijas numurs). Possessing the correct TIN is crucial for ensuring compliance with Latvian tax regulations for both individuals and businesses. All information presented in this guide is verified from official sources, including the State Revenue Service (Valsts ieņēmumu dienests) and other trusted government publications.
