Mauritania numbering plan & how to dial
Mauritania uses an open numbering plan under country code +222. After the country code, a 2-digit area or mobile prefix is followed by a 6-digit subscriber number, giving a 8-digit national number. Domestic numbers are often written with a leading trunk "0" that is omitted when dialing Mauritania from abroad.
Mauritania has 27% internet penetration and is served by 3 major mobile networks (Mauritel, Mattel, Chinguitel). VoIP is permitted and regulated by Autorité de Régulation (ARE). The local currency is Mauritanian Ouguiya and the primary language is Arabic, French, 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 +222 country code to reach Mauritania.
Keeping the national trunk "0"
If a Mauritania number is written with a leading 0 for domestic use, omit that 0 after the +222 country code when calling from abroad.
Ignoring the time difference
Mauritania runs on UTC+0. Check local hours before dialing so calls don't land outside business time.
