Greece numbering plan & how to dial
Greece uses an open numbering plan under country code +30. After the country code, a 2-digit area or mobile prefix is followed by a 8-digit subscriber number, giving a 10-digit national number. Domestic numbers are often written with a leading trunk "0" that is omitted when dialing Greece from abroad.
Greece has 82% internet penetration and is served by 3 major mobile networks (Cosmote, Vodafone Greece, Wind Hellas). VoIP is permitted and regulated by EETT (Hellenic Telecommunications and Post Commission). The local currency is EUR and the primary language is Greek, which shape IVR prompts, SMS content, and business-hours handling.
Most European numbering plans follow ITU-T E.164 with a national trunk prefix that is dropped for international dialing, and cross-border VoIP is widely supported across the region.
Skipping the exit code
Greece calls from the US need 011 first, then +30 — the exit code isn't optional.
Keeping the national trunk "0"
Greece numbers often show a domestic leading 0 — drop it once you've dialed the +30 country code from outside the country.
Ignoring the time difference
Greece runs on UTC+2. Check local hours before dialing so calls don't land outside business time.

FAQ
Calling Greece — frequently asked questions
Greece's area or mobile prefix is 2 digits, dialed right after the +30 country code and before the 8-digit subscriber number. Missing or mistyping that prefix is one of the most common reasons a call to Greece fails to connect.
Greece uses an open plan: a separate 2-digit area or mobile prefix followed by a 8-digit subscriber number. The prefix is what routes the call to the right region or network once it lands in the country.
Calls from Greece to the US start at $0.009/min on Twiching, billed per second rather than rounded up to the minute. That rate applies regardless of which of the major local carriers the call originates on.
Greece's local currency is EUR, which is worth factoring into any pricing or invoicing shown to customers there. Twiching's own per-minute rates to and from Greece are quoted in USD regardless of the local currency.
Over Tier-1 direct interconnects with major local networks like Cosmote, rather than lower-quality wholesale transit routes. That direct-carrier approach is what keeps delivery rates and call clarity high.
The US exit code is 011 for any international call, including to Greece. It comes right before the +30 country code, and Twiching adds both automatically when you dial from the app, so you only need to enter the local number.
