If you’re moving to Greece, two numbers will quickly become the most important digits in your life: your AFM (tax identification number) and your AMKA (social security number). Without them, you can’t open a bank account, sign a rental agreement, access healthcare, or even set up a phone contract.
What Is an AFM (ΑΦΜ)?
AFM stands for Arithmos Forologikou Mitroou — Greece’s Tax Identification Number. Think of it as the equivalent of a US Social Security Number for tax purposes or a UK National Insurance Number.
You need an AFM for: opening a bank account, signing a lease or buying property, starting employment or freelance work, paying taxes, signing utility contracts, and buying a car.
What Is an AMKA (ΑΜΚΑ)?
AMKA is your Social Security Registration Number. You need it for: accessing the Greek public healthcare system (ESY), employment, prescriptions at pharmacies, and enrolling children in public schools.
Get Your AFM First
Visit the appropriate DOY (tax office). If you already live in Greece, go to the local DOY for your area. If you are a non-resident, go to the DOY Katoikon Exoterikou (Tax Office for Foreign Residents) at Metsovou 4, 1st Floor, 106 82 Athens (near Omonoia), tel: 210 8204631. Hours: Mon-Fri 7:30-14:30.
Online option: You can now start the process through myAADE, though identity verification still needs a video call or in-person visit. Most non-EU applicants should appoint a tax representative (accountant/lawyer). Bring your valid passport, visa/residence permit (non-EU), proof of address, and the M1 application form. You’ll typically receive your AFM the same day, often within an hour.
Then Get Your AMKA
Visit a KEP (Citizens’ Service Center) with your passport, residence permit, proof of address, and AFM number. Your AMKA is usually issued the same day, within 30 minutes.
For Non-EU Citizens
Getting an AMKA as a non-EU citizen can be more complicated. Some KEP offices may require additional documentation. Ask about the PAAYPA (Provisional AMKA for Third-Country Nationals) if you encounter difficulties.
Common Challenges
“They told me to come back tomorrow” — System outages happen. Try Tuesday or Wednesday (Mondays and Fridays are busiest).
“I need a translated document” — Some offices require certified Greek translations via the Ministry of Foreign Affairs translation service.
“I don’t have proof of address yet” — A hotel booking or signed declaration from your host (with their ID) can sometimes work.
After You Have Both Numbers
Once you have your AFM and AMKA, you can: open a bank account, sign a rental lease, register for healthcare, start working, and set up utilities.
Frequently Asked Questions
Can I get an AFM before arriving? In some cases, yes — through a tax representative (lawyer or accountant).
Is AFM the same as VAT number? Your AFM becomes your VAT number if you register for business. Add prefix “EL” for EU VAT purposes.
Do I need to renew my AMKA? No, it’s permanent. Update info at EFKA if your status changes.
