Nigeria phone number validator
How the phone number format works
- Format
- Nigeria phone number in national or international (+234) format
- Example
- +2348021234567
Things to watch for
- Accepts national or international (E.164, e.g. +234...) format
- Validated with Google's libphonenumber; confirms the number is possible/valid for this country, not that it is currently assigned or reachable
^[+]?[0-9 ()\-]{6,}$A Nigerian mobile number is 11 digits in national form, starting with a two-digit prefix — 070, 080, 081, or 090 — followed by eight more digits (0803 123 4567). That leading 0 is a trunk prefix, dropped the instant +234 is added, so a number written domestically as 08031234567 becomes +2348031234567 internationally: 10 digits after the country code, not 11.
How this validator works
Type the number in national form (08031234567) or full international form (+2348031234567); this tool checks the 11-digit national length and the mobile prefix against Nigeria’s real numbering plan using Google’s libphonenumber, entirely client-side. The most common failure here is a kept leading 0 after +234 — typing +2340803123 4567 instead of +2348031234567 — which changes the digit count and fails validation immediately.
What a pass doesn’t tell you
A pass confirms the number matches a real Nigerian mobile shape — it doesn’t confirm the SIM is active or currently reachable. Nigeria’s large, fast-moving prepaid mobile market means a well-formed number can be recycled to a new owner soon after it goes quiet.
Scope: catch a missing digit, a wrong prefix, or a leftover 0 after +234 before a Nigerian number reaches a form or SMS platform — not proof it’s reachable today.

phone number FAQ
Why does a Nigerian mobile number lose a digit when written as +234?
The leading 0 in 0803 123 4567 is a national trunk prefix, not part of the subscriber number — it's dropped the moment +234 is added, so the correct international form is +2348031234567: ten digits after the country code, not eleven.
How many different mobile prefixes does Nigeria use?
Several ranges are in active use — 070, 080, 081, and 090 among them — reflecting how Nigeria's mobile numbering has expanded in blocks as demand grew, rather than a single fixed prefix the way some smaller countries use.
Does a valid check confirm a Nigerian number is currently active?
No. It only confirms the digits match a real Nigerian mobile pattern recognized under the NCC's numbering plan — not that the SIM is currently active or reachable, which needs a carrier-side lookup this tool doesn't perform.
