How to write a Costa Rica number in E.164
- Remove spaces, dashes, dots and brackets so only digits are left.
- Costa Rica has no trunk prefix, so keep every digit of the national number.
- Put +506 in front. The result has 8 digits after the country code for a mobile.
So 8312 3456 becomes +50683123456. E.164 is the format SMS gateways, dialers and most CRMs store; see the E.164 format explained for why.
Mobile or landline?
Costa Rica 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.
