Greek VAT number lookup (ΑΦΜ)

Enter a Greek VAT number and see the business name, tax office, address, whether it is active and its activities, from AADE's public registry service. The number is checked for validity first.

The business details will appear here: name, tax office, address, status and activities.

Data come from AADE's public business registry service.

In short

A Greek business's basic details (name, tax office, address, status and activity codes) are held in the AADE registry and can be looked up by its VAT number (ΑΦΜ). A Greek VAT number has 9 digits and the last one is a check digit, so a mistyped digit is caught at once. The eFluper lookup validates the number first, then fetches the details from AADE's registry service.

01How a Greek VAT number is validated

A Greek VAT number has 9 digits. The first 8 are multiplied by 256, 128, 64, 32, 16, 8, 4 and 2 respectively and the products are added up. The remainder of that sum divided by 11 (taking 10 as 0) must equal the 9th digit.

This catches most typing mistakes, but it does not say whether the number belongs to an existing or active business. That is why the tool then queries the AADE registry.

02Where the details come from

The details come from AADE's public service for looking up basic registry data, the same service invoicing software uses to fill in customer details. The VAT number you enter is used only for the lookup.

If the AADE service is unavailable, the VAT number validity check still works.

How do I find a Greek company's details from its VAT number?

Enter the VAT number in the lookup and press "Look up". The name, tax office, address, status and activities come from the AADE registry.

How do I check whether a Greek VAT number is valid?

The 9th digit of a Greek VAT number is a check digit derived from the first 8. The tool runs the check as you type and tells you at once whether the number is valid.

How many digits does a Greek VAT number have?

Nine. In intra-EU transactions it is written with the EL prefix, e.g. EL123456789. The tool accepts both forms.

Can I see whether the business is active?

Yes. The result card shows whether the business is active or inactive, according to the AADE registry.

Why were no details found for a valid VAT number?

A number can be valid without belonging to a business, for example when it belongs to an individual with no business activity. The AADE service may also be temporarily unavailable.

Does eFluper fill in details from the VAT number?

Yes. When you sign up for eFluper, your business details are filled in automatically from your VAT number.
