AMA, MITE or MAG? Which Greek registration number your property needs, where it must appear, and the fine if it is missing

Three owners, three different paths. The first rents an apartment through Airbnb and holds an 11 digit number from the Greek tax authority. The second runs a licensed hotel and holds a number of letters and digits from the Ministry of Tourism. The third runs rooms to let, filed a notification, and holds a 7 digit number that is neither of the other two. All three are required by law to display it, and all three usually fail to display it in the most obvious place: their own website.

If you own property in Greece and manage it from abroad, this is one of the easiest compliance gaps to fall into, because the number normally gets entered once on a platform and then forgotten.

This guide explains who needs which, how to tell them apart in two seconds by counting digits, and why the gap in the fines runs from 1,000 euro to tens of thousands.

A note: I am not an accountant. This guide is based on published legislation and official tax authority guidance, with sources at the end. Before making decisions with tax consequences, talk to your accountant in Greece.

The quick answer in one table

Most guides describe two numbers. There are three.

The critical point: you hold one of the three, never two. One status excludes the other.

The fastest test: count the digits. 11 means AMA. 7 means MAG. If it contains letters, it is an EOT licence number.

Who needs an AMA

The AMA, the Property Registry Number, covers short term rental: renting a property for less than 60 days per lease, providing nothing beyond bed linen, without a tourism operating licence. In other words, the classic Airbnb case.

Registration happens in the Short Term Stay Property Registry of the tax authority, online through the myAADE portal.

How many AMA numbers do you need? This is where most owners count wrong, because they count rooms. The rule is not how many spaces you have, it is how many you list separately. Decision POL.1187/2017 puts it plainly: if the manager lets more than one space in the same property as distinct listings on the platform, a separate registry number must be obtained for each of them.

So:

• You offer the property as a single space, one listing? One AMA, however many rooms it has.
• You list four suites separately, each with its own page? Four AMA numbers, registered under the "Partial Rental" option.

I see both ends of this among my own clients: one property listing four suites separately correctly holds four numbers, while another that is let as a whole correctly holds one.

Watch the format: the official tax authority guide specifies that the AMA has exactly 11 digits. If yours shows fewer, the leading zeros have usually been dropped. With one important exception, explained just below: if your number has exactly 7 digits, it is probably not a truncated AMA. It is a MAG.

Who needs a MITE number

The MITE, the Registry of Tourism Enterprises, covers those operating as a licensed tourism business: hotels, licensed rooms to let, tourist furnished residences. It presupposes a Special Operating Signal, meaning a licence, technical specifications and classification.

And here is the point that confuses most people: holders of an operating licence do not receive an AMA. The property is entered in the registry under its own number instead. This is not an oversight, it is an explicit exemption written into article 111.

And the third number: the MAG

Every guide forgets this one, and it is exactly the number a great many small Greek properties actually hold.

The MAG, the Unique Notification Number, is issued to anyone operating under a notification instead of a Special Operating Signal. Non principal tourist accommodation, meaning rented furnished rooms and apartments, tourist furnished residences and villas, no longer obtains an operating licence. They file a notification of operation and receive a MAG.

Three things worth keeping:

1. The MAG has 7 digits, as the tax authority guide specifies. The AMA has 11. That is the easiest way to work out which of the two you are holding.
2. A MAG holder does not receive an AMA. The property is entered in the registry under the MAG, exactly as happens with an operating licence number.
3. The MAG is displayed in place of the licence number, on the platforms and on every other means of promotion, your website included.

In practice: if you obtained a "licence" for rooms to let in recent years and the number you were given has 7 digits, you hold neither an AMA nor an EOT licence number. You hold a MAG, and that is what you must display.

Where exactly the number must appear

This is the most misunderstood part, and at the same time the easiest to fix.

For the AMA, article 111 par. 2 case b of law 4446/2016 says the registration number must "compulsorily accompany the listing of the property, in a visible place, on the digital platforms, as well as on every means of promotion". Decision POL.1187/2017 of the tax authority repeats the same wording.

The phrase "every means of promotion" leaves no room. Your website is a means of promotion. So are your social profiles.

For the MITE the law is even more categorical, because it names the media one by one. Article 165 par. 3 of law 4070/2012 lists "radio or television stations, the daily or periodical press, websites or blogs on the internet", and requires the number to be displayed "in such a way that it becomes clearly and legibly perceptible".

So for a licensed property, the obligation to show the number on the website is not an interpretation. It is written into the law with the word "websites".

The fines, and why they are not comparable

The gap here is dramatic and worth understanding clearly.

AMA: for failing to meet the conditions of par. 2 (not registering, or not displaying the number) the fine is 50% of the gross revenue of the tax year, with a minimum of 5,000 euro. You are given 15 calendar days to comply from the moment the breach is established, and if the same breach repeats within the same year, the fine doubles.

Do the arithmetic: a property turning over 30,000 euro faces a 15,000 euro fine.

MITE: a flat fine of 1,000 euro in favour of the EOT, by decision of the Head of the relevant Regional Tourism Office. A single amount per breach, independent of turnover.

The asymmetry follows from the logic of the two laws: one is a tax law aimed at undeclared activity, the other governs advertising conduct.

And enforcement is not theoretical. According to 2026 press reports, more than 2,100 listings without a valid AMA were deactivated during 2025.

What changed in May 2026

On 20 May 2026, Regulation (EU) 2024/1028 on data collection and sharing relating to short term rental services came into application across Europe. Three things change in practice:

1. Platforms must display the registration number on the listing.
2. They must make reasonable efforts to carry out random checks on its validity, on a regular basis.
3. Competent authorities gain the power to order the removal of listings without a valid number.

One important clarification: hotels and similar tourist accommodation are explicitly excluded from the scope of the regulation. It targets short term rental, not licensed hospitality. If you hold a MITE number, your obligations remain those of Greek law.

In practice, the era when the number was "something the tax office asks for" is over. It is now a data point platforms verify, and one whose absence can take you out of the market.

The 4 mistakes I see in practice

I recently went through the registration numbers on seven accommodation websites. Here is what went wrong, because you will probably find it on yours too:

1. A MAG mistaken for a broken AMA. The most insidious of the four, because it leads to a wrong "fix". You see a 7 digit number, you know an AMA needs 11, and you conclude it was cut off. It was not. It is a MAG and it is complete. Pad it with leading zeros to "make it 11" and you have just published a number that does not exist.

2. An AMA with one zero too many. On one site the number had been published with an extra leading zero, making it 12 digits. Invalid, however correct the real one underneath may be.

3. The wrong label. A site displaying "EOT / MITE" while the number underneath was an AMA. A guest will not notice. An inspector will.

4. Missing from the website entirely while sitting correctly on Booking. This is the most common case, and the easiest to fix: one line in the footer.

How to put it on the site properly

Nothing elaborate is needed. The law asks for a "visible place" and for "clarity and legibility", not a design solution.

• In the footer of every page, not only on the contact page. That way it is visible wherever the visitor lands.
• With the correct label: "AMA: 00001234567", "MAG: 1234567" or "MITE: ...", never mixed up.
• In every language of the site. If you have a Greek version, the number belongs there too.
• All of the numbers, if you list several spaces separately and hold more than one AMA.

On the sites I build, the number goes into the footer from day one, in every language, so the question never comes up.

And one thought beyond compliance

The registration number is not only a legal obligation. It is also a trust signal.

A guest who sees an official number on a website understands they are dealing with a declared business, not a listing that can vanish. In the Greek Hospitality Digital Census 2026, across the 3,152 websites measured, 88% did not even carry their address in machine readable form. The basic identity details are missing everywhere, and they are among the cheapest things to fix.
