02The basics

What is the country code for Republic of the Congo?

The code is +242, and the first thing to get straight is which Congo it reaches: this is the Republic of the Congo, capital Brazzaville — not its larger neighbour, the Democratic Republic of the Congo, which answers to +243 from Kinshasa just across the water. National numbers run to nine digits, so a full international number is +242 plus those nine.

Code +242 was assigned to Republic of the Congo by the ITU under the E.164 plan. The “+” means “dial your local international exit code”; on a mobile, press and hold 0 to type it.

+24200242011 24200 242

All four mean the same thing — they connect your call to Republic of the Congo.

03Dialing format

How to call Republic of the Congo from anywhere

Once you've confirmed it's +242 and not +243, the dial is straightforward: your exit code, then 242, then the nine national digits exactly as written — including a mobile's leading 0, which stays put.

04Number format

Republic of the Congo phone number format explained

Nine digits across the board, and the opening tells you the type. Landlines lead with 22 — a legacy of a fixed-line network that mobile has long since overtaken here. Mobiles open with a two-digit prefix (01, 04, 05, 06) whose leading 0 is genuinely part of the number, so it survives into the international form rather than being stripped.

Landline

22 + city code + subscriber (e.g., Brazzaville 22 28 ...). International: +242 22 28 xxx xx.

Mobile

Nine digits opening with 04, 05, or 06 (e.g., +242 06 612 34 56). That leading 0 stays — it's counted inside the nine.

07Time zone

Republic of the Congo time zone

Brazzaville and the rest of the country keep West Africa Time (WAT), UTC+1, steady all year — no daylight saving to track. Sitting just one hour off Paris, it stays naturally close to the French business clock, which matters given how much trade and diaspora ties run along that corridor.

US East Coast callers reach Congo's afternoon in their late morning. From Paris and Western Europe the day overlaps almost entirely — Congo trails by just an hour or matches you outright, so nearly any working hour connects.

Common mistakes when calling Republic of the Congo

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

Dialing +243 when you mean +242

this is the single most common error. +242 is the Republic of the Congo (Brazzaville); +243 is the Democratic Republic of the Congo (Kinshasa), a separate country directly across the river. One wrong digit and your call lands on the opposite bank.

Stripping the leading 0 off a mobile prefix

keep it: +242 06 ..., never +242 6 ...

Counting only eight digits

Congolese national numbers are nine.

Swapping the Brazzaville (22 28) and Pointe-Noire (22 29) landline prefixes

that one digit changes the city.

Pinning Airtel to 05 alone

it runs on 04 as well.

10Save money

Tips to reduce the cost of calling Republic of the Congo
