Getting Your Greek Tax Number When You Need It
You move to Greece, or you start a business, or you need to sign a lease and suddenly everyone asks for your AFM. The Amika Forologikou Mitrou. It sits at the center of everything financial in this country. Banks, utilities, employers, the tax office itself—all of it runs through that eight-digit number. I spent three weeks figuring out how to get one when I first arrived, and by the time I had it sorted, I knew enough to help other people who were stuck in the same confusing spot. There are two main paths. One is for people already living in Greece with a residence permit. The other is for foreigners who need the number before they arrive, often for remote work setups or property purchases. They follow different procedures and end up taking different amounts of your time. This is the standard path. You book an appointment with the independent authority for public revenue, which operates under the acronym AADE. The Greek name is the Independent Authority for Public Revenue, but nobody uses that in conversation. Everyone just says "tax office" or refers to the building by its neighborhood.
You need to go to your local fiscal service office. If you live in Athens, that means either the central building on Filellinon or one of the district offices. Thessaloniki has its own separate hub. Outside the big cities, you go to the nearest decomentralization office that handles fiscal matters. The appointment system is online now, which is a change from a few years ago when you stood in line at 7 AM with a piece of paper and hoped for the best. Bring these documents. Your passport, your visa or residence permit if you have one, proof of address in Greece, and a completed application form. The form is available at the office itself, but downloading it beforehand saves time. The staff will check everything, enter your details into the system, and issue the AFM on the spot. Usually within twenty minutes. Sometimes longer if the system is slow or the queue is heavy. I learned the hard way that the proof of address requirement is where most people get stuck. A utility bill in your name works. A rental contract works too, but only if it is registered. Unregistered contracts, which are common in Greece, sometimes get rejected at the window. I had a friend who showed up with a signed lease and was sent home because the landlord had never filed it with the tax office. She came back two days later after her landlord sorted it, and then waited another hour for her number.
The Remote Route for Non-Residents
If you do not live in Greece and need an AFM for a specific transaction, there is still a way. You submit an online request through the AADE portal. You create an account using your foreign passport details and answer a series of questions about why you need the number. Property purchase, opening a bank account, freelance work for a Greek company. The reason matters less than picking something accurate. Once the application lands in their system, it typically takes between ten and twenty working days to process. You will receive the AFM by email or you can download it from the portal. This route exists precisely for people in your situation, but it is not widely advertised. The portal interface is in Greek, which adds a layer of friction if you are not comfortable reading administrative language. The workaround I used when I was stuck on a technical detail was to ask my accountant in Greece to submit the form on my behalf. Accountants have their own professional login that bypasses some of the personal account restrictions. It cost me about fifty euros for the hour of their time, but it saved me three days of confusion and a couple of wrong submissions.

Common Problems People Hit
The first issue is the name mismatch. If your passport has a slightly different spelling than what appears on your residency paperwork, the system can reject the application. I once saw someone's name entered as "Papadopoulos" on one document and "Pappadopoulos" on another. Two P's instead of one. The clerk at the counter could not resolve it on the spot. The person had to go back to the migration office to get the documents aligned, then return to the tax office. That took another week. Another problem is the address. The tax office wants a Greek address, not a foreign one. If you are still searching for housing when you apply, you might use a hotel or a friend's place. That is allowed for the application, but you should update it once you move into a permanent address. The system does not automatically sync address changes. The third issue is timing. If you apply in the summer, between July and August, expect delays. The offices run on reduced hours and the processing backlog grows. I applied in late July and got my number on a Tuesday in August, but a colleague who applied the same week did not hear back until September. The difference was whether the clerk who processed the file happened to be present that week.
What to Do With Your AFM Once You Have It
Write it down somewhere safe. Not on a sticky note on your monitor, but in a password manager or a physical notebook you keep with your important documents. You will need it for tax filings, social security contributions, healthcare registration, and basically any official interaction with the Greek state. Losing the number is a real problem because replacing it involves the same paperwork you went through to get it in the first place. You also need to understand that the AFM is not the same as a VAT number. The tax identification number is personal or corporate depending on who holds it. If you start a business, the company gets its own AFM. You keep yours. They are separate. I watched a freelancer confuse the two and try to use his personal number for invoicing, which created a mess with his accountant that took months to untangle. There is also a distinction between the AFM and the DAITA code, which is a regional tax code tied to your municipality. Some forms ask for both. Most people fill in the AFM and leave the DAITA blank without realizing it might matter for certain municipal fees or local tax calculations. If you are dealing with property taxes or vehicle registration, having both numbers ready prevents extra trips to the office.
Edge Case: Expats Who Already Have an AFM From a Previous Stay
If you lived in Greece years ago and received an AFM then, it does not expire. The number follows you for life. I met someone who had moved back after a decade abroad and assumed he needed a new one. He did not. His old number was still active in the system. He saved himself a whole appointment by asking the clerk to look him up by passport number instead of submitting a fresh application. The verification took thirty seconds. This also applies if you previously worked in Greece through a foreign employer who withheld Greek social security contributions. The AFM was issued at that time and remains valid regardless of how long it has been since you used it.
When the Process Breaks Completely
There are scenarios where you cannot get an AFM through the normal channels. If you are undocumented, there is no path. The system requires a valid residence permit or a foreign passport with a documented reason for needing the number. If you are in the country illegally, you are stuck until your status changes. Another failure mode is when your passport details are flagged in the system for some reason. I do not know exactly what triggers this. It might be a previous application with incorrect data, a name match with someone else in the system, or an administrative error from years ago. The solution is to file a formal request for correction, which goes through a different department and can take several months. This is rare but serious when it happens. For most people, though, the process is straightforward. Book the appointment, bring the documents, show up on time, and walk out with your number. The whole thing should take less than an hour once you are in the building. The difficulty is almost always in the preparation phase, not the execution.
