Always drop the leading 0
Nigerian numbers are written domestically with a leading 0 (e.g., 0803 XXX XXXX). When dialing from the US, replace this 0 with +234. Dialing +234 0803… will fail.
Quick Answer
From the US, dial 011 + 234 + the Nigerian number (drop the leading 0). On a mobile phone, dial +234 followed by the 10-digit number. Sayfone offers calls to Nigeria for $0.34/min from your browser — no app download needed.

DIALING GUIDE
Follow these steps to reach any Nigerian mobile or landline number from a US phone or Sayfone in your browser.
From a US landline, dial 011. From a US mobile phone, you can press and hold 0 to get the + symbol, which replaces 011.
011 or +
Dial 234, which is Nigeria's country code assigned by the ITU. This routes your call to the Nigerian telephone network.
011 234 or +234
Nigerian numbers start with a 0 for domestic calls (the national trunk prefix). When calling internationally, drop this 0 and dial the remaining 10 digits. For mobile numbers, this means the mobile prefix (e.g., 803, 806, 810) plus the 7-digit subscriber number. For landlines, use the updated area code (e.g., 201 for Lagos, 209 for Abuja) plus the subscriber number.
011 234 803 123 4567 (mobile) or +234 201 123 4567 (Lagos landline)
Once you have entered the full sequence, press the call button. The complete number for a Nigerian mobile should be 011 + 234 + 10 digits (or +234 + 10 digits from a smartphone).

DIALING RULES
Nigerian number formats differ between mobile and landline, and a recent numbering change affects landlines. These rules help you avoid common mistakes.
Nigerian numbers are written domestically with a leading 0 (e.g., 0803 XXX XXXX). When dialing from the US, replace this 0 with +234. Dialing +234 0803… will fail.
All Nigerian mobile numbers follow the format +234 XXX XXX XXXX — a 3-digit mobile prefix (e.g., 803, 806, 810, 903) plus a 7-digit subscriber number, totaling 10 digits after the country code.
The NCC updated fixed-line numbers to a new 10-digit format by adding a '02' prefix. For example, old Lagos numbers starting with 01 became 0201 domestically. Internationally, dial +234 201 XXX XXXX for Lagos or +234 209 XXX XXXX for Abuja. If you have an older landline number, prepend '2' before the existing area code digit(s).
The US international exit code is 011 for landline dialing. On smartphones, you can use the + symbol instead, which is recognized globally. Both methods route to the same international network.
TIMING TIPS

TROUBLESHOOTING
If your call to Nigeria isn't connecting, check these common problems before trying again.
The most common mistake is dialing +234 0803… instead of +234 803…. The 0 is Nigeria's domestic trunk prefix and must be dropped for international calls.
Nigerian mobile numbers should be exactly 10 digits after +234 (e.g., +234 803 123 4567). If you're getting an error, count the digits and verify nothing is missing or extra.
Since January 2024, Nigerian landlines use a new 10-digit format with a '02' prefix. If you have an old 8-digit landline number (e.g., old Lagos 1 XXX XXXX), it may need to be updated to the new format (201 XXX XXXX).
Occasional call connection difficulties may occur due to network congestion, especially during peak hours in Nigeria. Try calling again after a few minutes.
Toll-free (0800), short codes, and emergency numbers (112) are generally not reachable from outside Nigeria. Only standard mobile and landline numbers can be dialed internationally.
