How do I dial mobiles vs landlines in Mauritania

Mauritania’s country calling code is +222. Mauritanian phone numbers follow a closed 8-digit plan (commonly written as XXXX XXXX), and there’s no national trunk prefix—so you don’t add or remove a leading “0” when switching between domestic and international dialing. Inside Mauritania, you typically dial the full 8 digits as written. From abroad, dial your international exit code (or +), then 222, then the same 8-digit number (for example: +222 45XX XXXX). The international access code when calling out of Mauritania is commonly 00.

The main “mobiles vs landlines” difference in Mauritania is the prefix block, not a classic city area-code system. Many landlines are allocated in fixed-line ranges that include locality-linked prefixes (for example, Nouakchott commonly begins with 45…, and some towns appear as 4513…, 4574…, etc.). Mobile numbers are also 8 digits, but are usually identified by operator prefix blocks such as 2X (Chinguitel), 3X (Mattel), and 4X (Mauritel). In practice, the safest way to store Mauritanian contacts is always in E.164 format: +222 followed by the full 8 digits—this avoids formatting errors across phones, apps, and countries.

What are the emergency numbers in Mauritania

What are the city and area codes in Mauritania

Dialing tip: Mauritania’s “area codes” are best treated as leading prefixes inside an 8-digit number (closed plan). So internationally you dial +222 + full 8 digits, and domestically you dial the same 8 digits—there’s no trunk 0 to drop.

Which mobile prefixes do mobile operators use in Mauritania

Dialing tip: If you’re using prefixes to infer the operator (for routing, pricing, or analytics), note that Mauritania is commonly listed as not having mobile number portability available—so prefixes are generally more stable than in MNP countries

Mobile Operator	Dialing Prefixes
Chinguitel	20, 21, 22, 23, 24, 26, 27, 28, 29 (format: +222 2X XX XXXX)
Mattel	30, 31, 32, 33, 34, 36, 37, 38, 39 (format: +222 3X XX XXXX)
Mauritel	40, 41, 42, 43, 44, 46, 47, 48, 49 (format: +222 4X XX XXXX)
