Understanding Guinea phone numbers
Guinea phone numbers are 9 digits after the +224 country code. The first digit tells you whether it's mobile or landline, and the first three digits usually identify the carrier.
Mobile numbers
All mobile numbers start with 6. The next two digits identify the carrier. The format is +224 6XX XXX XXX.
| Prefix | Carrier |
|---|---|
| 620-629, 660-669 | Orange Guinea |
| 650-659, 670-679 | MTN Guinea |
| 628, 655, 664 | Cellcom Guinea |
Some prefix ranges overlap between carriers due to number portability and historical allocations. When in doubt, just dial the full number.
Landline numbers
Landline numbers start with 3. Most are in Conakry (prefix 30). The format is +224 3XX XXX XXX. Landline penetration is low -- the vast majority of Guineans use mobile phones.
No trunk prefix
Guinea does not use a trunk prefix. The 9-digit number is the same for local and international calls. Just add +224 when calling from abroad.
Mobile carriers in Guinea
Orange Guinea
Orange is the largest mobile carrier in Guinea with the best network coverage. Numbers typically start with 620-629 or 660-669. Orange has invested more in rural infrastructure than the other carriers, so if you're calling someone outside Conakry, they're most likely on Orange. Orange Money is the dominant mobile money platform in the country.
MTN Guinea
MTN is the second-largest carrier. Numbers start with 650-659 or 670-679. MTN has strong coverage in Conakry and the main regional cities (Kankan, Labé, Nzérékoré) but thinner reach in remote areas. MTN Money competes with Orange Money for mobile payments.
Cellcom Guinea
Cellcom is the smallest of the three. Its numbers use various prefixes including 628, 655, and 664. Coverage is mostly limited to urban areas. Cellcom tends to compete on pricing to attract budget-conscious subscribers.
Don't confuse +224 with nearby codes
Guinea shares its name with two other countries, which causes constant confusion with country codes.
| Code | Country | Why it's confusing |
|---|---|---|
| +245 | Guinea-Bissau | Similar name, neighboring country. Completely different code. |
| +240 | Equatorial Guinea | Similar name, but in Central Africa, not West Africa. |
| +675 | Papua New Guinea | Same "Guinea" in the name but on the other side of the world. |
The +245 Guinea-Bissau confusion is the one that actually causes problems. Both countries are in West Africa, both are francophone (though Guinea-Bissau speaks Portuguese), and people routinely mix them up. If you're told "call Guinea," confirm which Guinea they mean.
Time zone considerations
Guinea uses Greenwich Mean Time (GMT/UTC+0) year-round. No daylight saving time.
| Your time zone | When it's 9 AM in Conakry | When it's 6 PM in Conakry |
|---|---|---|
| US Eastern (EST/EDT) | 4:00 AM / 5:00 AM | 1:00 PM / 2:00 PM |
| US Pacific (PST/PDT) | 1:00 AM / 2:00 AM | 10:00 AM / 11:00 AM |
| UK (GMT/BST) | 9:00 AM / 10:00 AM | 6:00 PM / 7:00 PM |
| Central Europe (CET/CEST) | 10:00 AM / 11:00 AM | 7:00 PM / 8:00 PM |
| Australia East (AEST/AEDT) | 7:00 PM / 8:00 PM | 4:00 AM / 5:00 AM next |
For callers in France, Guinea is 1 hour behind in winter (France is CET/UTC+1) and 2 hours behind in summer (France is CEST/UTC+2). Morning calls from Paris reach Conakry before the workday starts there.
Communication in Guinea
Business hours and availability
Businesses in Conakry generally operate from 8:00 AM to 5:00 PM, Monday through Friday. Government offices are harder to reach by phone and often close earlier. Friday afternoons are quieter (Guinea is about 85% Muslim). Saturday mornings are busy for markets and some shops. For personal calls, evenings after 7 PM and weekends are the best times to reach people at home.
Network quality
Call quality in Conakry is reasonable on Orange and MTN, though the network can get congested during peak hours. Outside the capital, coverage drops significantly. The main regional cities (Kankan, Labé, Nzérékoré, Kindia) have coverage, but the roads between them often don't. If a call doesn't connect, try again in a few minutes -- network congestion is more likely than a wrong number.
Language
French is the official language and what you'll hear in business and government settings. Pular (Fula), Malinké (Mandinka), and Susu are the three main local languages, each dominant in different regions. English is rarely spoken. If you're calling a Guinean number for business purposes, prepare to communicate in French.
The Guinea diaspora
Where Guineans settled
France has the largest Guinean diaspora, particularly in the Paris region. The connection goes back to the colonial period, though Guinea was the first French African colony to vote for independence in 1958. Significant communities also live in Senegal, Côte d'Ivoire, and Sierra Leone (neighboring countries with easier migration). In the United States, there's a notable Guinean community in New York City, especially in Harlem and the Bronx.
Why they call home
Remittances are a major income source for families in Guinea, and phone calls coordinate when and how money gets sent. Calls also increase during Muslim holidays (Tabaski/Eid al-Adha, Ramadan) and around the start of the school year in October. Since internet access in Guinea is limited and unreliable outside Conakry, voice calls are still the primary way diaspora members stay connected with family.

Common mistakes to avoid
Calling the wrong Guinea
There are three countries with "Guinea" in the name. +224 is Guinea (Conakry). +245 is Guinea-Bissau. +240 is Equatorial Guinea. If someone says "call my family in Guinea," ask which one. Guinea-Conakry is the most common reference, but don't assume.
Using the wrong digit count
Guinea numbers are 9 digits after +224. If you have a number with fewer digits, it may be outdated. Guinea has changed its numbering format in the past, so older contacts may have 7 or 8 digit numbers that are no longer valid.
Expecting English
Guinea is francophone. Unlike neighboring The Gambia or Sierra Leone, English is not widely spoken. Business calls, automated messages, and voicemail greetings will be in French. If you don't speak French, you may need a translator for anything beyond basic greetings.
Calling rural areas and expecting connection
Guinea's interior has limited cell coverage. If someone is in a village outside the regional capitals, they may only get signal by walking to a higher point or traveling to the nearest town. Failed calls don't always mean a wrong number.
