Greece phone number format

  • Country code +30
  • No trunk prefix

Reviewed by Sujan ThapaliyaLast updated

What does a Greece phone number look like?

10 digits, always. Landlines are written +30 2XX XXX XXXX and mobiles +30 69X XXX XXXX. In full international (E.164) format a Greece mobile is written +306912345678: the country code +30, and no spaces or punctuation.
The anatomy of a Greece phone number under ITU-T E.164: country calling code 30, then the national destination code, then the subscriber number, to a maximum of fifteen digits after the plus. Nationally a Greece number is written +30 2XX XXX XXXX; in E.164 the prefix and the spacing both come off.
National formatting is for people. E.164 is for databases, APIs, and caller ID — store Greece numbers in the right-hand form.

Validation

How to validate a Greece number

Validating a phone number is three separate checks, and conflating them is the usual source of bugs:

  1. Format: does it match the shape for Greece? 10 digits, always, after the country code .
  2. Allocation: is the prefix actually in use? A number can be the right length and still belong to an unallocated range.
  3. Reachability: is there a live subscriber? Only a carrier lookup (HLR or equivalent) answers that, and it is the only check that catches disconnected numbers.

For form validation, check format only and be permissive: accept spaces, dashes, brackets, and a leading 0 then normalise. Rejecting a real customer because they typed their own number the way they normally write it is a far more expensive error than storing one badly formatted row.

Store in E.164 (+306912345678) and format for display at render time. Storing the display format is how a database ends up with the same person recorded four different ways.

How do I tell a Greece mobile from a landline?
By the prefix. Mobiles follow the pattern +30 69X XXX XXXX, while landlines follow +30 2XX XXX XXXX.
Should I store phone numbers with the plus sign?
Yes. Store every number in E.164: leading +, country code, national number, no spaces or punctuation, up to 15 digits. It is the only format that is unambiguous internationally, and it is what makes deduplication work. Format for display, store canonical.
