Updated : October 29, 2026Why getting the Nigeria phone number format right matters more in 2026 than ever.
A Lagos landline saved in your contacts before 2024 is probably wrong today. That year, every Nigerian landline got two extra digits.
Add a missing exit code or an extra 0, and calls to Nigeria fail just as easily.
This guide gives you a clear Nigeria phone number example for each number type, the new area codes, and how to dial from the US and the UK.
What Is the Nigeria Phone Number Format?
Every Nigerian phone number uses three building blocks, and each one changes how you dial.
1. Explanation of Nigeria Phone Number Format
The Nigeria phone number format is +234 + area code or mobile prefix + subscriber number.
- Mobile: +234 803 123 4567
- Lagos landline: +234 201 234 5678
Inside the country, replace +234 with 0 (0803 123 4567).
Drop the leading 0 after the country code. Dial +234 803 123 4567, not +234 0803 123 4567.
2. Importance of the +234 Country Code
The Nigeria phone number code is 234. It routes your call to the right country, so you need it when calling from outside Nigeria or saving a Nigerian number on WhatsApp.
3. Overview of Nigeria’s Dialing Code System
Four codes cover almost every call you make to Nigeria. Here is what each one does and when to use it.
| Part | Code | When to use it |

Landline and mobile numbers in Nigeria look different, so here is how to spot each.
1. Nigeria Landline Number Example
A landline telephone number has a city area code and a subscriber number. Since 2024, the area code always starts with 20.
- Lagos: 0201 234 5678 → +234 201 234 5678
- Abuja: 0209 234 5678 → +234 209 234 5678
2. Nigeria Mobile Number Example
A Nigerian mobile number has 11 digits locally (0803 123 4567, or 0XXX xxx xxxx) and 10 in the international format (+234 803 123 4567). The first four digits show the mobile carrier that issued it, such as MTN, Glo, Airtel, or 9mobile.
- Every SIM in Nigeria must be linked to the owner's National Identification Number (NIN). Unlinked lines can be barred from making calls.
What Changed in Nigeria’s 2023 Area Code Reform?
Nigeria added a new prefix to every landline in 2023, making older listed numbers outdated.
In September 2023, the Nigerian Communications Commission (NCC) added “02” in front of every landline number. Both formats worked until December 31, 2023, and the new format became the standard on January 1, 2024. Mobile numbers did not change.
Update pre-2024 landline numbers in your contact lists. Add 20 after +234, or 02 at the start for local dialing.
How Do I Dial a Nigerian Phone Number from Abroad?
Calling Nigeria from abroad means swapping the leading 0 for your exit code and +234.
Your exit code is 011 from the US and Canada, 00 from the UK and most of Europe, or + on mobile phones.
1. Calling a Nigerian Landline Number
Dial your exit code + 234 + area code + subscriber number.
- From the US: 011 234 201 234 5678 (Lagos)
- From the UK: 00 234 209 234 5678 (Abuja)
2. Calling a Nigerian Mobile Number
Dial your exit code + 234 + the 10-digit mobile number. No area code is needed.
- From the US: 011 234 803 123 4567
- From the UK: 00 234 803 123 4567
3. How Nigeria’s Area Codes Are Structured
Each area code is 20 plus the city’s old dialing code without its 0. Major cities get 3-digit codes (201 Lagos, 209 Abuja) with a 7-digit subscriber number. Other cities get 4-digit codes (2064 Kano) with a 6-digit subscriber number. Either way, the number is 10 digits after +234.
Nigeria Area Codes by City and Mobile Prefixes by Network
Use these tables to find city area codes and mobile prefixes before you dial Nigeria.
1. Landline Number Examples by Major Nigerian Cities
Each major city has its own city area code. Use these examples to dial landline numbers in Nigeria from abroad.
| City | City area code | Example from abroad |
|---|---|---|
2. Mobile Number Examples by Region
Mobile numbers in Nigeria are not tied to a region. The prefix only shows the network that issued the number.
| Network | Mobile prefixes | Example from abroad |
|---|---|---|
- Nigeria introduced mobile number portability in 2013, so a prefix may not match the current network.
Best Time to Call Nigerian Phone Numbers
Nigeria runs on West Africa Time, so plan calls around local office hours and holidays.
Call between 9 AM and 4 PM West Africa Time (WAT), Monday to Friday. Nigeria stays on UTC+1 all year with no daylight saving.
- Best window: 10 AM to 12 PM WAT.
- Fridays: Avoid 1 to 2 PM, especially in the north, when many people attend Friday prayers.
- Holidays: Skip Easter, Workers’ Day (May 1), Democracy Day (June 12), Independence Day (October 1), Christmas, and the Eid holidays.
