How to Call Greece from the US

To call Greece from the US, dial 011 + 30 + the full 10-digit Greek number. Athens example: 011-30-210-XXXXXXX. Thessaloniki: 011-30-231-XXXXXXX. Greek mobile: 011-30-69X-XXXXXXX (every mobile starts with 69).

The 011 is the US international exit code. The 30 is Greece’s country code. Unlike Germany or France, there is no leading 0 to drop — Greece abolished its trunk prefix in 2002, so you dial all 10 digits as written. On a smartphone you can substitute + for 011, dialing +30 210 XXXXXXX.

How to dial Greece from the US

Follow these four steps every time:

1. Dial 011 — the US exit code for all international calls. On a mobile keypad, long-press 0 to enter + as a shortcut; + works identically to 011 on smartphones.
2. Dial 30 — Greece’s ITU-assigned country code under the E.164 numbering plan.
3. Dial the full 10-digit Greek number. This is the key difference from most of Europe: Greece scrapped its trunk prefix in 2002, so there is no leading 0 to remove. Athens numbers begin 21, Thessaloniki 231, and mobiles 69 — you dial every digit.
4. Dial nothing extra. The Greek number is already complete at 10 digits.

The complete pattern: 011 30 <full 10-digit number>.

If you see a Greek number already formatted with +30 (common on business cards and websites), replace the + with 011 from a US landline, or dial it as-is from a smartphone.

Greek area codes by city

Greek geographic numbers always begin with the digit 2. Area codes range from two to four digits, and the subscriber portion fills the remainder of the 10-digit total. Because there is no trunk prefix, the area code shown locally is the same one you dial from abroad.

City	Area code	Dial from US (after 011 30)
Athens	21	21 + 8 digits
Thessaloniki	231	231 + 7 digits
Patras	261	261 + 7 digits
Heraklion	281	281 + 7 digits
Larissa	241	241 + 7 digits
Volos	242	242 + 7 digits
Ioannina	265	265 + 7 digits

Athens is the only city with a two-digit area code (21) followed by an eight-digit subscriber number; most other cities use a three-digit code followed by seven digits. Either way the total is always 10 digits.

Greek mobile numbers do not use city area codes. Every mobile begins with 69 in the format 69X XXX XXXX. With number portability now standard, the third digit no longer reliably identifies the carrier — but any number starting 69 is a mobile.

How Greek numbering works

Greece operates a flat 10-digit national numbering plan. Every number — landline, mobile, or service — is exactly 10 digits whether you call it from across the street in Athens or from across the Atlantic.

The defining feature is the absence of a trunk prefix. Most European countries (Germany, France, the UK) require you to drop a domestic leading 0 when dialing internationally. Greece removed that 0 in 2002, folding it permanently into the published number. So Greek numbers look the same domestically and internationally — you simply prepend 011 30 (or +30) and dial.

Geographic numbers start with 2; mobile numbers start with 69. There is no zero to add or subtract, which makes Greece one of the most forgiving European countries to dial.

Time zones: EET and EEST

Greece observes a single time zone nationwide, switching twice a year:

• EET (Eastern European Time) — UTC+2, in effect from the last Sunday of October through the last Sunday of March (Greece’s winter time).
• EEST (Eastern European Summer Time) — UTC+3, in effect from the last Sunday of March through the last Sunday of October.

US time zone	Offset during EET (Oct–Mar)	Offset during EEST (Mar–Oct)
Eastern (ET)	Greece +7 h	Greece +6 h
Central (CT)	Greece +8 h	Greece +7 h
Mountain (MT)	Greece +9 h	Greece +8 h
Pacific (PT)	Greece +10 h	Greece +9 h

Important for business callers: the US and EU do not switch clocks on the same Sunday. For roughly two weeks each spring and fall, Greece’s offset from US time is temporarily an hour different than usual — worth confirming when you schedule recurring calls.

The reliable overlap window for standard business hours is 8 AM–11 AM ET, which reaches Greek offices between roughly 2 PM and 6 PM local time before most close for the day.

US to Greece calling costs

Costs vary significantly by calling method:

• US carrier per-minute (no plan): AT&T and Verizon charge approximately $2–$3 per minute to Greece without an international add-on. Fine for an occasional call.
• Carrier international add-on packages: roughly $5–$15 per month reduces rates to approximately $0.05–$0.25 per minute. Worthwhile above about 30 minutes a month.
• VoIP providers (including DialPhone): flat per-minute rates to Greece that typically undercut carrier add-ons, with no monthly minimum. For US–Greece business calling at any volume, a VoIP plan on DialPhone business phone usually pays for itself quickly.
• Free app-to-app (WhatsApp, Viber): works only if the Greek side also uses the app over Wi-Fi or data. Viber is especially popular in Greece, but app calling is not viable for reaching most landlines or businesses.

Calls to Greek mobile numbers (the 69 range) are often priced higher per minute than landlines on US carrier plans. VoIP providers including DialPhone typically apply a single flat rate regardless of landline versus mobile destination.

Calling Greek mobile vs landline from the US

From a US perspective the dialing procedure is identical: 011 30 <full 10-digit number>. The difference is in the number itself:

• Landlines start with 2 and carry a geographic area code (2–4 digits) plus a local number, totaling 10 digits.
• Mobiles start with 69, have no area code, and are also 10 digits.

You can tell the two apart at a glance: any Greek number beginning 2 is a landline or geographic line, and any number beginning 69 is a mobile. There is no digit to drop in either case — a welcome simplification compared with the leading-0 rules of Germany and France.

SMS to Greece and business use cases

US-to-Greece SMS works from most US mobile plans — the same international add-on that covers calls usually covers texts. Use +30 followed by the full Greek mobile number. Business-grade SMS (A2P, bulk, or CRM-triggered) requires a provider that supports international SMS routing to Greek networks.

US–Greece B2B context where this matters most:

• Shipping and maritime: Greece controls one of the world’s largest merchant fleets, and US logistics, insurance, and finance firms coordinate constantly with Piraeus-based shipping offices. Time-zone management and recognizable caller ID are critical.
• Tourism and hospitality: US travel operators and hotel groups working with Greek destinations benefit from a presence in the local +30 namespace so callbacks land in a familiar format.
• Technology and services: US companies selling into the growing Greek tech and outsourcing sector find that a verified caller ID measurably improves answer rates.

DialPhone routes US-to-Greece calls with STIR/SHAKEN attestation, so your outbound caller ID passes carrier verification rather than appearing as an unverified international number — a meaningful factor for answer rates.

FAQ

Calling Greece FAQ

What is the country code for Greece? +

Greece's country code is +30. From a US landline or mobile, you reach it by dialing the US international exit code 011 first, making the full prefix 011 30. From a smartphone that supports E.164 dialing you can substitute + for 011, so +30 works identically.

Do I need to drop a leading 0 when calling Greece from the US? +

No — and this is where Greece differs from most of Europe. Greece abolished its trunk prefix (the leading 0) in 2002. Greek numbers are a flat 10 digits with no leading 0 to remove.

You dial all 10 digits exactly as written after 011 30. For example, an Athens number 210 1234 567 is dialed from the US as 011 30 210 1234 567. There is nothing to drop, which makes Greek dialing simpler than Germany or France.

How do I call a Greek mobile number from the US? +

Greek mobile numbers always start with 69 and are 10 digits long in the format 69X XXX XXXX. Dial 011 + 30 + the full mobile number.

Example: a number written 697 123 4567 is dialed from the US as 011 30 697 123 4567. Number portability means the third digit no longer identifies a specific carrier, but every Greek mobile begins with 69.

What is the best time to call Greece from the US? +

Greece is 7 hours ahead of US Eastern Time during standard time (EET, UTC+2 vs UTC-5) and 6 hours ahead when both regions are on summer time (EEST). The reliable business-hours overlap is 8 AM–11 AM ET, which lands in the 2 PM–6 PM range in Greece — still within office hours.

The US and EU change clocks on different Sundays each spring and fall, so for a couple of weeks the offset can shift by an hour. Confirm the local time before scheduling recurring calls.

How much does it cost to call Greece from the US? +

Standard US carrier rates without an international plan run roughly $2–$3 per minute to Greece. Carrier international add-on packages (about $5–$15 per month) reduce this to roughly $0.05–$0.25 per minute.

VoIP providers including DialPhone charge flat per-minute rates to Greek destinations that are typically lower than carrier add-on plans, with no monthly minimum for low-volume callers.

Can I call Greek toll-free (00800) numbers from the US? +

Greek freephone numbers use the 00 800 format and are free only when dialed from within Greece. From the US they usually will not connect, or they route through standard international channels at a normal per-minute rate — never toll-free.

Ask your Greek contact for their geographic +30 number (such as an Athens 21x or Thessaloniki 231x line) as a reliable alternative.

What is the difference between EET and EEST for calling Greece? +

EET (Eastern European Time) is UTC+2 and applies from late October to late March — Greece's standard time, 7 hours ahead of US Eastern. EEST (Eastern European Summer Time) is UTC+3 and applies from late March to late October, making Greece 6 hours ahead of US Eastern during that period.

Greece switches on the last Sunday of March and the last Sunday of October. Because the US and EU change on different dates, the offset can briefly differ by an hour during transition weeks.

How do I save a Greek number in my phone contacts? +

Save Greek numbers in full E.164 international format: +30 followed by the complete 10-digit number. For example, an Athens number 210 1234 567 should be saved as +30 210 1234 567.

Because Greece has no trunk prefix, you store the number exactly as written — nothing to add or remove. This format works from any country, prevents dialing errors when roaming, and is the standard expected by CRMs and VoIP platforms including DialPhone.
