Introduction
In Greece, the Tax Identification Number (TIN), known locally as “Αριθμός Φορολογικού Μητρώου” (ΑΦΜ), is a unique identifier assigned to individuals, businesses, and legal entities for tax purposes. Possessing the correct TIN is crucial for ensuring compliance with Greek tax regulations. All information provided in this guide is verified from official sources, including the Independent Authority for Public Revenue (Ανεξάρτητη Αρχή Δημοσίων Εσόδων – AADE).

TIN Format and Structure
The Greek TIN (ΑΦΜ) consists of nine digits. The structure is as follows:
- First Eight Digits: Sequential numbers that uniquely identify the taxpayer.
- Ninth Digit: A checksum digit used for validation purposes.
The format strictly adheres to the guidelines set by the AADE.

TIN and VAT Number Connection
In Greece, the TIN (ΑΦΜ) also serves as the VAT (Value Added Tax) number. For businesses, the VAT number is prefixed with the country code “EL” followed by the nine-digit TIN. For example:
- VAT Number Format: EL123456789
This dual use simplifies tax processes and aligns with the European Union’s VAT identification system.
Importance of Accurate TIN Validation
Accurate TIN validation is vital for:
- Ensuring Compliance: Proper TIN usage is mandatory for tax reporting and legal transactions.
- Avoiding Penalties: Incorrect TINs can lead to fines, legal issues, and delays in processing tax documents.
- Facilitating Transactions: Valid TINs are essential for business operations, including invoicing and cross-border trade within the EU.
Why Accurate TIN Validation Matters
Ensuring the accuracy of your TIN is critical for both businesses and individuals in Greece. An incorrect or unverified TIN (AFM) can lead to serious complications such as:
- Delays in tax processing
- Rejection of tax exemption claims
- Fines and penalties for non-compliance
- Rejection of e-invoicing submissions
- Onboarding unqualified suppliers or customers
- Data quality issues across finance and compliance systems
