Gibraltar phone number format

How do you format a Gibraltar phone number?

Write a Gibraltar phone number with the country code +350. A mobile looks like 57123456 inside Gibraltar and +350 57123456 from abroad. Mobiles have 8 digits after the country code, and the E.164 form is +35057123456. A format check confirms the digits fit the numbering plan, not that the number is in service.

How to write a Gibraltar number in E.164

  1. Remove spaces, dashes, dots and brackets so only digits are left.
  2. Gibraltar has no trunk prefix, so keep every digit of the national number.
  3. Put +350 in front. The result has 8 digits after the country code for a mobile.

So 57123456 becomes +35057123456. E.164 is the format SMS gateways, dialers and most CRMs store; see the E.164 format explained for why.

Mobile or landline?

Gibraltar allocates separate number ranges to mobiles and landlines, so a numbering-plan check reads the line type straight from the digits, for free. That type describes the range the number came from. It doesn’t prove the number is connected today.

Mobile, landline and special number ranges in Gibraltar

A Gibraltar mobile number starts with 51, 5250, 5251, 54, 56–58, 6010, 6011, 606 after +350. Every valid number of each type below starts with one of the digit groups shown. A number that starts the right way can still be unassigned: the groups say what a range is for, not that a number is connected.

Can you tell if a Gibraltar number is a mobile?
Usually, yes. Gibraltar numbers come from ranges allocated separately to mobiles and landlines, so a numbering-plan check reads the line type from the digits. It tells you what the range is for, not whether the number is in service.
Does a valid format mean a Gibraltar number is in service?
No. A valid format means the digits fit a range Gibraltar's numbering plan allocates. It cannot tell whether the number is connected today or who carries it, because numbers are reassigned and ported. A live carrier lookup reports the current carrier and line type, but even that does not prove someone answers.
