Getting a Tax Registration Number (AFM) in Greece

Researched from official sources ยท June 3, 2026

An ฮ‘ฮฆฮœ (AFM โ€” Tax Registration Number) is the root identifier of Greek public-services onboarding.

A bank account, a social-security number, and most residence formalities all assume you already hold one. It is issued free by the AADE (Independent Authority for Public Revenue) through the myAADE portal, at a local tax office, or at a Citizen Service Centre. Final identity verification by video call or in person is always required.

Estimated time

The attribution step itself completes in about one day in office; most applicants in Greece receive their number within two to three business days. Applying from abroad, allow one to three weeks once document legalisation and any tax-representative coordination are included.

Additional Items

  • Service existence rests on the Tax Procedure Code (Law 4174/2013, Government Gazette 170/A), Articles 10-11 on tax registration; procedural detail is set by POL Circular 1006/2013.
  • Minors and persons lacking legal capacity apply through a legal representative.
  • Holding an AFM is a prerequisite for downstream steps including opening a bank account, obtaining a social-security number, and most residence formalities.

Step-by-Step

  1. 1

    Prepare your identity and supporting documents

    1. Gather your passport or ID, and proof of address if you are an EU/EEA national resident in Greece
    2. Non-EU residents add a residence permit in force or evidence of legal residence
    3. Where applicable, add apostilled and translated foreign documents and the tax-representative appointment document

    ๐Ÿ’ก Tip: Authentication must precede translation. A missing Apostille or consular visa is a frequent cause of rejected non-resident applications, so legalise foreign documents before you start.

  2. 2

    Submit the application

    ฮ”ฮŸฮฅ

    1. For natural persons the process runs electronically through AADE
    2. A resident in Greece may instead attend in person at the competent local *ฮ”ฮŸฮฅ* (DOY โ€” local tax office) or a *ฮšฮ•ฮ * (KEP โ€” Citizen Service Centre) point of single contact
    3. Residents abroad submit exclusively electronically through the 'TIN & Authentication Key' application of the myAADE digital portal

    โš ๏ธ Watch out: Without a postal address in Greece you must name a tax representative at the time of application; non-resident applications are not processed without one.

  3. 3

    Verify your identity

    1. Book a slot for the verification step that matches your channel
    2. For the video-call route you are verified against your passport by a myAADElive employee
    3. For the in-person route you attend an appointment at the local tax office

    ๐Ÿ’ก Tip: Do not assume the AFM can be fully issued online with no verification step โ€” "final identity verification is always required either through a video call (myAADElive) or an in-person appointment at the local tax office (known as DOY)". The online form alone does not complete attribution.

  4. 4

    Receive the kleidarithmos (authentication key)

    ฮบฮปฮตฮนฮดฮฌฯฮนฮธฮผฮฟฯ‚

    1. For remote receipt, your details are cross-checked with your mobile-phone or payment-service provider; once your mobile number is confirmed, TaxisNet sends the first part of the *ฮบฮปฮตฮนฮดฮฌฯฮนฮธฮผฮฟฯ‚* (kleidarithmos) by e-mail and the second part by SMS
    2. Alternatively you receive the key during the myAADElive video call
    3. Or in person at the tax office by booking through the 'My Appointments' application

    ๐Ÿ’ก Tip: The kleidarithmos is the activation key that lets you log in to TaxisNet / myAADE, so keep both e-mail and SMS parts together until you have completed activation.

  5. 5

    Receive your AFM and authentication key

    1. Once your identity is verified, the AFM and authentication key are issued electronically
    2. Note the number โ€” a bank account, a social-security number, and most residence formalities will ask for it
    3. Activate your TaxisNet / myAADE login with the kleidarithmos so you can access online tax services

FAQ

General

Is there a fee for the AFM?

No. The AFM is attributed free of charge โ€” this is cross-checked across two official-portal sources. The only possible charge is the fee of a privately engaged tax representative, used mainly by non-residents, which is set by that representative and not by the State.

Where is the AFM issued?

By the AADE (Independent Authority for Public Revenue) โ€” through the myAADE digital portal with a myAADElive video-call verification, at a competent local ฮ”ฮŸฮฅ (DOY โ€” local tax office), or at a ฮšฮ•ฮ  (KEP โ€” Citizen Service Centre) point of single contact. Residents abroad apply only through the myAADE electronic application.

Do I need a residence permit to get an AFM?

EU/EEA nationals do not โ€” a passport or ID card plus proof of address suffices. Non-EU nationals residing in Greece must submit a residence permit in force or evidence of legal residence. The residence permit is an input to the AFM application; the AFM itself does not confer or evidence legal residence.

Do I need a tax representative?

Only if you have no postal address in Greece โ€” that is, if you are applying as a non-resident. You appoint a ฯ†ฮฟฯฮฟฮปฮฟฮณฮนฮบฯŒฯ‚ ฮตฮบฯ€ฯฯŒฯƒฯ‰ฯ€ฮฟฯ‚ (tax representative), typically a Greece-resident lawyer or accountant, at the time of application, by a written declaration with authenticated signature or a solemn declaration available via myAADElive; a notarial document is also accepted.

How long does it take?

The attribution step itself completes in about one day in office, and most applicants in Greece receive the AFM within two to three business days. Applying from abroad, the full process can run one to three weeks once document legalisation and representative coordination are included.

What is the kleidarithmos and how do I get it?

The kleidarithmos is the authentication key that activates your TaxisNet / myAADE login. It is issued together with the AFM โ€” remotely with the first part sent by e-mail and the second by SMS after your mobile number is confirmed, via the myAADElive video call, or in person at the tax office.

    Attribution of a Tax Registration Number (AFM) and registration in the tax register is mandatory for every person, natural or legal, domestic or foreign, who is liable to pay or withhold tax or to submit any declaration under tax legislation. Submission channels are the local tax offices, Points of Single Contact (KEP-EKE), and the myAADE platform for natural persons electronically. The attribution is provided without cost with a processing time of one day. Service existence is grounded in Law 4174/2013 (Tax Procedure Code), with non-EU foreign nationals residing in Greece required to submit a residence permit for work in accordance with applicable law.

    gov.gr (Hellenic unified digital portal) โ€” AADE natural-person AFM and authentication-key page 2026-06-03

    For a natural person the AFM application is made through AADE's digital channels (the myAADE portal) or in person at a local tax office (DOY). Alongside the AFM the applicant receives an authentication key (kleidarithmos) that allows login to TaxisNet. Final identity verification is always required, either through a video call (myAADElive) or an in-person appointment at the local tax office. EU/EEA citizens apply with a valid passport or ID card, a completed M1 form, and proof of address; obtaining the AFM is a free process apart from any representative's fees.

    AADE (Independent Authority for Public Revenue) โ€” non-resident issuance page 2026-06-03

    Tax residents abroad submit a request exclusively electronically through the 'TIN & Authentication Key' application of the myAADE portal. Once the taxpayer confirms their mobile-phone number, TaxisNet automatically sends the authentication key's first part by e-mail and the second part by SMS; alternatively the key is received via a myAADElive video call. Non-residents without a Greek postal address must appoint a tax representative. Foreign public documents must be authenticated and officially translated into Greek, with authentication preceding translation and bearing either the Apostille notation for Hague Convention countries or a consular visa for other cases.
