Eritrea phone number format

How do you format a Eritrea phone number?

Write a Eritrea phone number with the country code +291. A mobile looks like 07 123 456 inside Eritrea and +291 7 123 456 from abroad, dropping the leading 0. Mobiles have 7 digits after the country code, and the E.164 form is +2917123456. Format alone never shows a line is in service.

Example Eritrea phone numbers

These are the example numbers from Google’s libphonenumber data, the same numbering-plan data our validator uses, written three ways.

How to write a Eritrea number in E.164

1. Remove spaces, dashes, dots and brackets so only digits are left.
2. If the number starts with the trunk prefix 0, remove it. It is only used when dialling inside Eritrea.
3. Put +291 in front. The result has 7 digits after the country code for a mobile.

So 07 123 456 becomes +2917123456. E.164 is the format SMS gateways, dialers and most CRMs store; see the E.164 format explained for why.

Mobile or landline?

Eritrea 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 Eritrea

A Eritrea mobile number starts with 171–173, 7 after +291. 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 Eritrea number is a mobile?

Usually, yes. Eritrea 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 Eritrea number is in service?

No. A valid format means the digits fit a range Eritrea'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.
