Nigerian Phone Number Formatter

This tool cleans up and converts Nigerian phone numbers between the local format (0803 123 4567), the international format (+234 803 123 4567), and the E.164 format (+2348031234567) that apps and APIs expect. Paste a number in any of those shapes and it normalises all three — and tells you the likely network operator.

Why the format matters

• Saving contacts — store numbers in +234 form so they work when you travel or message from abroad.
• SMS & payment APIs — services like bulk SMS and gateways require the E.164 form (+234…) with no leading zero.
• Spreadsheets & CRMs — a consistent format keeps your contact list clean and de-duplicated.

Local, international, and E.164

A Nigerian mobile number has 10 significant digits. Locally it's written with a leading 0 (0803…). Internationally the 0 is replaced with the country code +234. E.164 is the same as the international form but with no spaces — the canonical machine format. This tool strips spaces, dashes, and brackets and rebuilds each version correctly.

Network detection

The operator is inferred from the number's prefix (for example 0803 and 0703 are MTN; 0805 is Glo; 0802 is Airtel; 0809 is 9mobile). Note that numbers can be ported between networks, so the original prefix isn't a guarantee of the current carrier.
