El Salvador phone number format

How do you format a El Salvador phone number?

Write a El Salvador phone number with the country code +503. A mobile looks like 7012 3456 inside El Salvador and +503 7012 3456 from abroad. Mobiles have 8 digits after the country code, and the E.164 form is +50370123456. A format check confirms the digits fit the numbering plan, not that the number is in service.

How to write a El Salvador number in E.164

  1. Remove spaces, dashes, dots and brackets so only digits are left.
  2. El Salvador has no trunk prefix, so keep every digit of the national number.
  3. Put +503 in front. The result has 8 digits after the country code for a mobile.

So 7012 3456 becomes +50370123456. E.164 is the format SMS gateways, dialers and most CRMs store; see the E.164 format explained for why.

Mobile or landline?

El Salvador 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.

Can you tell if a El Salvador number is a mobile?
Usually, yes. El Salvador 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 El Salvador number is in service?
No. A valid format means the digits fit a range El Salvador'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.
