Eritrea numbering plan & how to dial
Eritrea uses an open numbering plan under country code +291. After the country code, a 1-digit area or mobile prefix is followed by a 7-digit subscriber number, giving a 8-digit national number. Domestic numbers are often written with a leading trunk "0" that is omitted when dialing Eritrea from abroad.
Eritrea has 22% internet penetration and is served by 1 major mobile networks (EriTel). VoIP is restricted and Ministry of Information (Eritrea Telecommunications Services Corporation – EriTel) licenses only approved operators. The local currency is ERN and the primary language is Tigrinya, which shape IVR prompts, SMS content, and business-hours handling.
Across African markets, mobile-first numbering dominates and Tier-1 interconnects are the key to consistent call delivery and CLI presentation.
Skipping the exit code
From the US you must dial 011 before the +291 country code to reach Eritrea.
Keeping the national trunk "0"
If a Eritrea number is written with a leading 0 for domestic use, omit that 0 after the +291 country code when calling from abroad.
Ignoring the time difference
Eritrea runs on UTC+3. Check local hours before dialing so calls don't land outside business time.
Using non-compliant routes
VoIP into Eritrea is restricted by Ministry of Information (Eritrea Telecommunications Services Corporation – EriTel); grey routes are blocked or dropped, so licensed termination is required for reliable delivery.
