You receive a call from a number starting with +30 and you don’t know where it comes from. This prefix is assigned to Greece. Each member country of the International Telecommunication Union (ITU) has its own code, and +30 identifies all fixed and mobile numbers registered in Greek territory, including the islands of the Aegean and Ionian Seas.
Greek numbering: how +30 fits into the global plan
The ITU organizes telephone codes by geographical areas. Zone 3 covers Southern Europe and part of the Mediterranean basin. Within this zone, Greece is the only country with the +30 code.
Unlike other European countries, Greece has adopted a so-called “closed” system: the initial zero is an integral part of the local number. When dialing a Greek number from abroad, you keep this zero after the +30. For example, to reach a contact in Athens, you dial +30 followed by the full ten-digit number, zero included.
If you are looking to find out which country uses the +30 code, the answer is one word, but the way to dial the number deserves special attention to avoid call failures.
Calling Greece from France: the exact sequence to dial
From a French landline, the sequence starts with 00 (international exit prefix), followed by 30, then the Greek number. From a mobile, the + sign replaces the 00. You may have already noticed that some calls fail even though the number seems correct?
The most common mistake is omitting the zero from the Greek number. In France, it is customary to remove the first zero when calling most countries. Greece is an exception: this zero is structural, it is not a local access prefix.
Here is the summarized procedure:
- From a mobile: dial +30 followed by the full Greek number (ten digits starting with a zero for landlines, starting with 69 for mobiles)
- From a landline: dial 00 30 then the full number
- From Greece to France: dial 00 33 then the French number without the initial zero
The reverse direction follows the classic logic. To call a French number from Athens or Thessaloniki, the exit prefix remains 00 and the French code is 33, with the zero omitted this time.
Greek area codes and mobile numbers: distinguishing the origin
Within the country, the first two digits after the +30 code indicate the type of line and the region of origin. Fixed numbers start with 2, mobiles with 69.
For example, a number starting with 210 corresponds to the Athens area. A number starting with 2310 refers to Thessaloniki. The islands have their own regional prefixes: 2241 for Rhodes, 2281 for the Cyclades.
Greek mobile numbers are all structured the same way: 69x followed by seven digits. The main operators in the country assign distinct ranges within this range, but for the foreign caller, the distinction does not affect dialing.
Special and premium-rate numbers in Greece
Some Greek numbers starting with 80 are free lines, while those starting with 90 are premium-rate. From abroad, Greek free numbers generally do not work. They are reserved for calls made from within the national territory.
Another point to know: the Greek telecommunications regulator (EETT) has recently tightened the regulation of services billed via mobile billing. A new Code of Ethics requires explicit consent for any billing of digital content via special numbers, with a default spending cap set at 20 euros per month per service, excluding taxes. This measure protects consumers against involuntary subscriptions to premium services.
Telemarketing from Greece: what the legislation provides
Are you receiving a commercial call from a number starting with +30? The Greek legal framework regulates these practices. Article 11 of law 3471/2006 requires operators to maintain a register of subscribers refusing telemarketing.
The penalty is deterrent. Article 14 of this same law provides for a minimum compensation of 10,000 euros for moral damage in cases of illegal telemarketing harassment. This minimum amount is among the highest in Europe for this type of offense.
If you receive unsolicited calls from a +30 code, two reflexes are useful:
- Check if the number corresponds to a recognized operator or service before calling back
- Never provide banking or personal information over the phone, even if the caller claims to be an official organization
- Block the number directly from your smartphone if the call repeats
Cost of a call to Greece and digital alternatives
The rates for a call to a number starting with +30 vary depending on your operator and plan. From France, most mobile plans include calls to Greek landlines and mobiles in their “Europe” package, as Greece is part of the European Economic Area.
While roaming from Greece, your calls are charged as if you were in France thanks to European roaming regulations. You can call a French or Greek number without extra cost, within the limits of reasonable use defined by your operator.
For extended calls or regular business communications, VoIP applications remain a complementary option. They operate over the internet and bypass per-minute billing, provided you have a stable connection.
The +30 code does not hold any major technical surprises once the peculiarity of keeping the zero is well understood. Greece remains the only territory associated with this prefix, and the dialing rules have been stable since the closure of the Greek numbering plan. Just keep in mind that special and premium-rate numbers follow their own accessibility rules depending on your calling location.
