Under country code +291, Eritrea numbers follow an open plan built from a 1-digit area or mobile prefix and a 7-digit subscriber line — 8 digits in all. A domestic "0" typically precedes the prefix, but that digit is dropped when dialing Eritrea internationally.
Carriers & language
1 major networks cover Eritrea (EriTel), against 22% internet penetration. VoIP is restricted and Ministry of Information (Eritrea Telecommunications Services Corporation – EriTel) licenses only approved operators. Because Tigrinya is the primary language and ERN the local currency, both should inform IVR scripts, SMS content, and support hours.
Africa context
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
Eritrea calls from the US need 011 first, then +291 — the exit code isn't optional.
Keeping the national trunk "0"
If an 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
Before dialing Eritrea, check the local clock — it runs on UTC+3, and off-hours calls tend to go unanswered.
Using non-compliant routes
Because Ministry of Information (Eritrea Telecommunications Services Corporation – EriTel) tightly regulates VoIP in Eritrea, only licensed routes deliver reliably; grey routes risk being blocked outright.
Compliance, carriers & rates for Eritrea
Restricted — EriTel licensed only
Regulated by Ministry of Information (Eritrea Telecommunications Services Corporation – EriTel)
Ministry of Information (Eritrea Telecommunications Services Corporation – EriTel) restricts VoIP termination in Eritrea to licensed operators, so unlicensed grey routes are routinely blocked or degraded. Twiching terminates strictly on compliant, licensed paths built to clear that bar.
- EriTel, a state-owned monopoly, is the sole licensed telecom provider in Eritrea.
- Private and independent VoIP services are not permitted under current regulations.
- All international telecommunications traffic must route through state-controlled gateways.
Direct Tier-1 interconnect with EriTel — no wholesale transit in between.

How businesses use an Eritrea number
Asmara-recognisable numbers
Callers in Asmara and across Eritrea see a familiar +291 prefix rather than a number they don't recognise and won't pick up.
Africa outbound & support
Run sales and support lines into Eritrea over Tier-1 routes that interconnect with networks like EriTel.
Time-zone-aware routing
Calls into Eritrea route to whichever team is on shift for UTC+3, instead of ringing a desk that's already gone home.
No local carrier contract needed
Entering Eritrea over SIP trunking skips the local carrier contract entirely — the number is provisioned and billed the same way as every other Twiching market.
FAQ
Calling Eritrea — frequently asked questions
1 major networks serve Eritrea: EriTel. Twiching interconnects directly with these carriers over Tier-1 routes rather than relying on third-party transit.
The US exit code is 011 for any international call, including to Eritrea. It comes right before the +291 country code, and Twiching adds both automatically when you dial from the app, so you only need to enter the local number.
Tigrinya is the primary language in Eritrea — IVR prompts, SMS copy, and support scripts should be written in it for the best response rates. Getting the greeting and menu options right in the local language is often the difference between a caller staying on the line or hanging up.
Yes — Twiching interconnects directly with EriTel and other major Eritrea networks over Tier-1 routes for consistent call delivery. That direct interconnect is what keeps answer-seizure ratios high compared to routing through third-party wholesale transit.
Calling Eritrea means dialing 011, then +291, instead of the domestic US format — plus accounting for the UTC+3 time difference. Domestic US calls skip both the exit code and the international country code entirely.
The two most common slip-ups are forgetting the 011 exit code before +291, and keeping a domestic leading "0" that should be dropped. Both mistakes result in the call failing to connect rather than reaching the wrong number.
