02The basics

What is the country code for Mauritania?

Area code 222 is the international country code for Mauritania, officially the Islamic Republic of Mauritania — a vast country stretching from the Atlantic coast into the Sahara, bordering Western Sahara, Algeria, Mali, and Senegal.

Mauritania's numbering plan is refreshingly simple: an 8-digit national number with no domestic trunk prefix to add or drop. Whatever the number looks like written locally, that's exactly what follows +222 when dialing from abroad — nothing to strip, nothing to add.

If you only remember one thing: there's no 0 to drop. Mauritania has no domestic trunk prefix at all, so a number written locally as `45 XX XX XX` becomes `+222 45 XX XX XX` internationally — identical, just with +222 in front.

All four mean the same thing — they connect your call to Mauritania.

03Dialing format

How to call Mauritania from anywhere

Calling Mauritania from abroad is a three-part sequence: your exit code, then 222, then the 8-digit national number exactly as written. From the US: 011 222 XX XX XX XX. From the UK/EU: 00 222 XX XX XX XX. From any mobile: +222 XX XX XX XX, letting your phone substitute the correct exit code automatically.

04Number format

Mauritania phone number format explained

A Mauritanian number is built from two parts: +222 (country code) and an 8-digit national number. Geographic landline prefixes exist (45 for Nouakchott, 25 for parts of the interior including Kiffa and Rosso), while mobile numbers are distinguished by operator-block prefixes — roughly the 2X range for Chinguitel, 3X for Mattel, and 4X for Mauritel, alongside additional allocated ranges for each. The country moved from 7-digit to 8-digit numbers in 2011, so any 7-digit listing predates that change and needs updating.

Landline

Geographic prefix (45 Nouakchott, 25 interior) + subscriber number, 8 digits total. Example: 45 XX XX XX → +222 45 XX XX XX.

Mobile

Operator-block prefix (2X Chinguitel, 3X Mattel, 4X Mauritel, plus additional allocated ranges) + subscriber number, 8 digits total. Example: 2X XX XX XX → +222 2X XX XX XX.

Mauritania mobile network prefixes

The prefix after +222 tells you which network issued the SIM — though number portability means it no longer guarantees the operator.

Mauritel

+222 3X, and additional ranges including 61–63, 66, 71–73

backed by Tunisie Telecom.

owned by Sudatel (Sudan); the newest of the three national operators.

07Time zone

Mauritania time zone

Mauritania keeps Greenwich Mean Time (GMT, UTC+0) year-round, with no daylight saving at any point in the year. It shares this fixed offset with much of coastal West Africa, including Senegal and The Gambia.

Because Mauritania never shifts but the US and UK do, the practical gap changes only on the calling side — in UK winter, Mauritania and the UK share the exact same clock; the gap only opens up once British Summer Time begins.

Best call windows

Mauritania's business day (roughly 9:00 AM–5:00 PM GMT) overlaps almost entirely with a UK working day in winter, with zero time-zone conversion needed. From the US East Coast, an early morning-to-midday call (roughly 5:00 AM–12:00 PM ET in winter) lands inside Mauritania's business hours.

Common mistakes when calling Mauritania

Almost every failed international call is a formatting issue, not a network issue.

Looking for a trunk 0 to drop

Mauritania has no domestic trunk prefix, so the 8-digit national number is dialed the same way at home and from abroad — just add +222 in front.

Miscounting the digits

The national significant number is exactly 8 digits. Older listings from before the 2011 renumbering (when Mauritania moved from 7 to 8 digits) will be one digit short.

Assuming a prefix guarantees the carrier

Mattel and Chinguitel both hold multiple, sometimes overlapping-looking prefix ranges, and number portability means a given prefix is a hint, not a guarantee, of the current network.

Assuming daylight saving applies

Mauritania stays on GMT (UTC+0) all year — the gap to the US or UK shifts only when their own clocks change, not Mauritania's.

Confusing +222 with a neighboring West African code

Mauritania borders Western Sahara, Algeria, Mali, and Senegal — each with its own distinct country code. Double-check the full three digits before dialing from memory.

10Save money

Tips to reduce the cost of calling Mauritania

Dial with + from a mobile

Using +222 lets your phone substitute the correct exit code automatically, avoiding the 00 vs 011 mix-up between regions.

Save contacts in full international format

Store Mauritanian numbers as +222 XX XX XX XX (no leading 0) so the same contact dials correctly from anywhere you travel.

Route calls over VoIP or a virtual number

Legacy carrier international rates into Mauritania can be steep; a virtual +222 number or VoIP routing typically costs materially less for regular calling.

Batch calls into Mauritania's business day

A roughly 9:00 AM–5:00 PM GMT window overlaps comfortably with both a European working day and the US East Coast morning — plan one shared slot rather than repeat-dialing.

11For business

Why businesses get a Mauritania virtual number

Mauritania sits at a genuine crossroads — Arab and West African, Sahara and Atlantic coast — with an economy built on fishing, iron ore, and a growing energy sector, alongside significant international development and humanitarian activity. A +222 virtual number gives a business or organization a real local presence in Nouakchott without opening a physical office, useful for trade, NGO field coordination, and diaspora connections alike.

Higher answer rates

A familiar +222 caller ID gets picked up more readily than an unfamiliar international number.

Support NGO and development work

Mauritania hosts significant humanitarian and development activity — a local virtual line helps coordinate field staff and partners without a permanent office.

Cheaper inbound for local callers

Callers in Mauritania reach your line at local rates instead of paying international charges.

Centralized routing

Calls to your +222 number route to any team, anywhere in the world.

Faster market entry

Stand up a Mauritanian presence in days rather than opening a local entity.

Real PSTN presence

A genuine, dialable Mauritanian number on the public telephone network, not a call-forwarding relay.
