Under country code +222, Mauritania numbers follow an open plan built from a 2-digit area or mobile prefix and a 6-digit subscriber line — 8 digits in all. A domestic "0" typically precedes the prefix, but that digit is dropped when dialing Mauritania internationally.
Carriers & language
3 major networks cover Mauritania (Mauritel, Mattel, Chinguitel), against 27% internet penetration. VoIP is permitted and regulated by Autorité de Régulation (ARE). Because Arabic, French is the primary language and Mauritanian Ouguiya 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
Mauritania calls from the US need 011 first, then +222 — the exit code isn't optional.
Keeping the national trunk "0"
Mauritania numbers often show a domestic leading 0 — drop it once you've dialed the +222 country code from outside the country.
Ignoring the time difference
Mauritania runs on UTC+0. Check local hours before dialing so calls don't land outside business time.

FAQ
Calling Mauritania — frequently asked questions
Mauritania's local currency is Mauritanian Ouguiya, which is worth factoring into any pricing or invoicing shown to customers there. Twiching's own per-minute rates to and from Mauritania are quoted in USD regardless of the local currency.
Yes — since Mauritania runs on UTC+0, calls can be routed to the right team based on local business hours there. That's especially useful for support or sales teams covering multiple countries across different time zones from one platform.
Yes, where locally supported — a single Twiching Mauritania number can handle both voice calls and SMS. That avoids the overhead of provisioning and managing two separate numbers for one customer-facing line.
A recognisable +222 number tends to get answered more often than an unfamiliar international one — that's the main reason to present local caller ID in Mauritania. Unknown foreign numbers are frequently screened or ignored, which can quietly suppress answer rates on outbound sales and support calls.
Mauritel is among the largest networks in Mauritania, and Twiching interconnects directly with it for Tier-1 delivery. Direct interconnects like this are what keep call quality and answer rates consistent instead of relying on lower-tier transit.
Twiching rates to Mauritania start at $0.31/min, and calls back from Mauritania to the US start at $0.23/min. Both directions are billed per second rather than rounded up to the nearest minute, on Tier-1 routes throughout.
