Questions
What is the country code for Greece?
Greece's country calling code is +30. In E.164 — the format almost every API, SMS gateway and CRM expects — it is written with no spaces, brackets or dashes, like +306912345678.
How many digits is a Greece phone number?
10 digits after the +30 country code. Written nationally it may show no trunk prefix.
Does the leading 0 get included when dialling Greece from abroad?
Greece numbers do not use a national trunk prefix, so the national and international digits are the same after the +30 country code.
Is a correctly formatted number the same as a real one?
No, and conflating the two is the usual mistake. Formatting only says a number could exist. It does not say whether the range was ever allocated, whether it is mobile, fixed line or VoIP, or whether it is worth trusting on a signup — those need a lookup against numbering-plan data.
