How to Get TAXISnet Codes for AADE and gov.gr Logins
Almost every Greek online service asks for TAXISnet codes. How to register, how to get the key number (kleidarithmos) and what to do when the login fails.
TAXISnet codes are the username and password issued by AADE, the Greek tax authority, and they log you in to myAADE, gov.gr and most Greek e-services. You need an AFM tax number first. You register online, then confirm your identity with a one-time key number (kleidarithmos) that AADE gives you at a tax office or through a video call. The codes are free.
Without them, simple tasks become office visits: registering a lease, booking a vaccine, getting a certificate or filing a tax return. Most newcomers get the codes in their first weeks in Greece.
What do you need before you start?
- An AFM tax number registered at a tax office (DOY).
- A valid passport or ID card.
- An email address and a mobile number you will keep, ideally a Greek one.
- For non-residents abroad: AADE’s online process for issuing an AFM and key together, described below.
How do you register for TAXISnet codes?
The process has two parts: you apply online for a username and password, then AADE confirms who you are with the key number. As of November 2026 it runs through myAADE, the authority’s portal.
- On myAADE, open AFM and key number, then Key number, and choose initial registration for a natural person acting for yourself.
- Enter your AFM, personal details, email and mobile number.
- Get the key number in one of the ways in the table below.
- Back on myAADE, enter the key number with your AFM and choose your username and password.
- Confirm the email and phone number when AADE sends codes.
| Way to get the key number | Who it suits |
|---|---|
| In person at a tax office (DOY), with ID | People in Athens who can visit an office; ask whether an appointment is needed |
| Video call through myAADElive, by digital appointment | Anyone who prefers not to queue, including some non-residents |
| Online form for non-residents, with an authenticated identity document | People abroad who need an AFM and key together |
AADE describes the non-resident route on its page about issuing an AFM and key number. Menu names in myAADE change from time to time, so look for the words “key number” or “kleidarithmos” if a label differs.
What can you do once you are logged in?
The same codes work across hundreds of public services. Common uses for new residents:
- File the yearly income tax return (E1) and see your tax assessment.
- Register or check a rental lease on the AADE platform, which every landlord must declare; our guide to renting an apartment in Athens explains why that registration matters to tenants.
- Change your address, marital status or tax residence.
- Issue certificates on gov.gr, such as proof of address or a solemn declaration (ypefthyni dilosi) with a digital signature.
- Check your AMKA social security number and EFKA insurance record, and book vaccines or tests where the platform offers it.
- Use the gov.gr Wallet app for digital documents.
Some AADE applications use separate special access codes instead of your main login. AADE explains these on its page on special access codes.
How do you fix common login problems?
| Problem | What usually helps |
|---|---|
| Forgot username or password | Use the reminder and reset options on the myAADE login page; codes go to the email and mobile on file |
| Email or mobile on file is old | Update contact details in myAADE while logged in, or ask the tax office if you can no longer log in |
| Account locked after several attempts | Wait and try again later, then reset the password |
| gov.gr service asks for a one-time code you never receive | Check that your mobile number is registered and verified in myAADE and in the national contact registry |
| Name shown in Greek letters | Normal; your record is kept in Greek. Spelling errors are fixed by the tax office |
If nothing works, AADE’s helpline my1521 (phone 1521 from Greece) can guide you, or visit the tax office with your passport.
When in your move should you get the codes?
Right after the AFM. The codes are needed for the next steps of a typical first month: the landlord declares your lease on AADE, you confirm it with your login, and the AMKA, utility contracts and many employer forms then refer back to the same record. People who wait until tax season usually end up queuing at a tax office in spring, when the tax return season opens and offices are busiest.
If you change address, marry or move abroad later, update the record through the same login. A wrong address on AADE can delay tax refunds and official letters.
Can an accountant or someone else use my codes?
Do not share your codes. Accountants have their own authorized access and file on your behalf through an authorization you give in myAADE. Anyone holding your codes can sign declarations in your name on gov.gr.
Bottom line
Register the codes with a Greek mobile number you plan to keep, since most gov.gr services send one-time codes by SMS and a dead foreign SIM is the most common reason newcomers get locked out. Write down the username separately from the password; AADE usernames are hard to recover.

Can I get TAXISnet codes without an AFM?
No. The AFM comes first. Non-residents can request both together through AADE’s online process.

No. They are separate logins. TAXISnet is the standard login for Greek public services; keep your bank codes for your bank.
