The numbers and facts you need before you dial.
What is the country code for Liberia?
The country code for Liberia is +231. It's the international dialing prefix assigned to Liberia by the ITU, placed at the front of any Liberian number when written in full international format.
Liberia has a genuinely unusual claim to global timekeeping history: it was the last country in the world to adopt a conventional, standardized UTC time offset, only switching to Greenwich Mean Time on 7 January 1972 after generations of keeping its own idiosyncratic local mean time based on Monrovia's exact longitude.
Liberian numbers use a domestic trunk 0 that's dropped when dialing from abroad. Landlines are identified by a 2-digit prefix (21 or 22 for Monrovia), while mobile numbers run through one of three operators: Orange Liberia, Lonestar Cell MTN, or Cellcom.
If you only remember one thing: Liberia was the last country on Earth to standardize its time zone. It kept its own unique local offset until 1972 — a fact that surprises most people who assume every country adopted GMT-based zones long ago.
All four mean the same thing — they connect your call to Liberia.
How to call Liberia from anywhere
Calling Liberia from abroad is a three-part sequence: your exit code, then 231, then the area or mobile prefix and subscriber number, with the domestic trunk 0 dropped. From the US: 011 231 21 XX XXXX. From the UK/EU: 00 231 77 XX XXXX.
Full example: +231 21 XX XXXX — a Monrovia landline, country code plus area prefix plus subscriber number.
Liberia phone number format explained
A Liberian number is built from +231, a domestic-only trunk 0 (dropped internationally), and an 8-digit national number consisting of a 2-digit area or mobile prefix plus a 6-digit subscriber number. Landline prefixes (21, 22) are used in Monrovia, while mobile numbers use prefixes like 77 (Orange), 88 and 555 (Lonestar Cell MTN), and additional ranges for Cellcom.
Landline
Area prefix (21/22 Monrovia) + 6-digit subscriber number.
Mobile
Operator prefix (77 Orange, 88/555 Lonestar Cell MTN, additional ranges for Cellcom) + subscriber number, all under +231.

Liberia mobile network prefixes
The prefix after +231 tells you which network issued the SIM — though number portability means it no longer guarantees the operator.
Orange Liberia
One of Liberia's two major mobile network operators.
Lonestar Cell MTN
One of Liberia's two major mobile network operators, part of the pan-African MTN Group.
Cellcom
A smaller mobile operator alongside Orange and Lonestar Cell MTN.
Liberia time zone
Liberia keeps Greenwich Mean Time (GMT, UTC+0) year-round, with no daylight saving. This is a relatively modern arrangement: Liberia only adopted GMT on 7 January 1972, having kept its own local mean time (based on Monrovia's exact geographic meridian) for generations before that — making it the last country in the world to standardize its time zone.
Because Liberia never shifts but the US and UK do, the practical gap to your location changes only when your own clock moves — Liberia's side of the calculation stays constant year-round.
Since Liberia keeps a fixed UTC+0 offset with no daylight saving, UK callers get an exact clock match during UK winter, while US callers should aim for their morning to catch the Liberian afternoon.

Common mistakes when calling Liberia
Almost every failed international call is a formatting issue, not a network issue.
Assuming Liberia has always used GMT
It hasn't — Liberia kept its own idiosyncratic offset (Monrovia Mean Time, roughly UTC-0:44:30) until 7 January 1972, making it the last country in the world to standardize to a conventional UTC offset.
Keeping the trunk 0 when dialing internationally
The leading 0 is domestic-only — a Monrovia landline is +231 21 XX XXXX, never +231 021.
Assuming Liberia observes daylight saving
It doesn't — Liberia stays on GMT (UTC+0) all year, so the gap to the US or UK shifts only when their own clocks change, not Liberia's.
Assuming a single mobile operator
Liberia's mobile market is served by three private operators (Orange, Lonestar Cell MTN, Cellcom) rather than a state monopoly.
Confusing Liberia with Libya
The names look similar in shorthand, but they are entirely different countries on different continents with different codes — Liberia is +231, Libya is +218.
Tips to reduce the cost of calling Liberia
Drop the leading 0 internationally
A Monrovia number written locally as 021 XX XXXX becomes +231 21 XX XXXX from abroad.
Time calls to the GMT business day
Liberia shares its clock with the UK during UK winter, and much of coastal West Africa year-round — a straightforward reference point for scheduling.
Route calls over VoIP or a virtual number
Legacy carrier international rates into Liberia can be steep; cloud-routed calling typically costs materially less.
Confirm which currency a quote uses
Liberia commonly uses both the Liberian dollar and the US dollar in everyday transactions — clarify which currency any pricing or invoice refers to.
Why businesses get a Liberia virtual number
Liberia's economy centers heavily on iron ore and rubber exports, alongside a shipping-registry sector (Liberia has one of the world's largest ship registries by tonnage) and significant international development activity following past periods of civil conflict. A +231 virtual number gives a business a local presence for trade, shipping, or development-sector coordination without opening a physical office in Monrovia.
Higher answer rates
A familiar +231 caller ID gets picked up more readily than an unfamiliar international number.
Support shipping-registry and trade sectors
Liberia's large ship registry and export economy drive significant international business communication.
