Introduction
In Uruguay, the Tax Identification Number (TIN) is a crucial element for individuals, businesses, and entities to comply with tax regulations. The TIN facilitates accurate tax reporting, financial transactions, and legal compliance. All information presented in this guide is verified from official sources, including the Dirección General Impositiva (DGI), Uruguay’s tax authority.
Tax ID Number Types
Uruguay utilizes the Registro Único Tributario (RUT) as its official TIN system.
- RUT (Registro Único Tributario): This is the primary TIN used in Uruguay for tax identification purposes.
The RUT is mandatory for all entities engaging in economic activities within Uruguay, including individuals, corporations, sole proprietorships, and foreign entities operating in the country.
TIN Format and Structure
The RUT in Uruguay follows a specific and officially defined format:
- Format: 12-digit numeric code
Structure:
- First 2 digits: Indicate the series (e.g., newer RUTs start with “22” as per the October 2024 DGI update)
- Next 8 digits: Unique taxpayer identifier
- Next 1 digit: Branch identifier (in some cases)
- Final digit: Check digit (used for validation)
This standardized format ensures a unique and verifiable identifier for each taxpayer.

This integration simplifies the compliance process for both tax registration and VAT obligations.
Importance of Accurate TIN Validation
TIN validation is critical for:
- Ensuring proper tax filing and reporting
- Avoiding delays in invoicing and financial operations
- Preventing penalties from the DGI
- Supporting accurate cross-border business transactions
Always use the official DGI portal for validation to ensure accuracy and compliance.
