All information provided in this guide is verified from official sources, ensuring accuracy and reliability.​

Tax Identification Number Types

Liechtenstein utilizes the PEID Nummer as the sole TIN for both individuals and entities. There is no separate TIN for businesses or legal entities; the PEID Nummer serves all purposes.​

  • Format: The PEID Nummer consists of 4 to 12 digits, all numeric.​
  • Structure: The number is a continuous string without any separators or country code.​

    • -1: Checksum digit.​

This format is used for VAT registration and related transactions. ​

Importance of Accurate TIN Validation
