In Andorra, the Tax Identification Number (TIN), known locally as the “Número de Registre Tributari” (NRT), is a unique identifier assigned to individuals, businesses, and legal entities for tax purposes. Possessing the correct NRT is essential for ensuring compliance with Andorra’s tax regulations. All information presented here is verified from official sources, including the Andorran tax authority. 

## **Tax Identification Number Types** 

Andorra utilizes the Número de Registre Tributari (NRT) as its sole TIN for all taxpayers, encompassing: 

- **Individuals**: Both residents and non-residents.
- **Businesses**: Companies operating within Andorra.

This format ensures each NRT is unique and can be systematically validated.
