What Is a USSD Code?
USSD means Unstructured Supplementary Service Data. It is a communication method that allows you to interact directly with your mobile network by dialing a short code from your phone.
Unlike many mobile applications, USSD generally does not require an internet connection. This makes it useful when you have no data, poor internet connectivity, or simply want to perform a quick task without opening an app.
For example, you can dial a code such as *310#, press the call button, and follow the options displayed by your network.

How to Check Your BVN Using USSD Code in Nigeria
Aside from airtime and data, one of the most common USSD lookups in Nigeria is retrieving a Bank Verification Number (BVN). If you cannot remember your BVN or need it quickly for a banking transaction, you can retrieve it directly from your phone without visiting a bank branch.
| BVN Service | USSD Code |
|---|---|
| Retrieve/check BVN | *565*0# |
| Validate a BVN (NIBSS) | *565*1# |
How to Check Your BVN with *565*0#
Dial *565*0# from the phone number linked to your bank account, then follow the prompt shown on screen. Your 11-digit BVN will be displayed, so have something to write with ready, or take a screenshot immediately.
A small service charge (typically around ₦20) is usually deducted from your airtime balance for each retrieval. This code works across MTN, Airtel, Glo and 9mobile, and is provided by the Nigeria Inter-Bank Settlement System (NIBSS) in partnership with Nigerian banks.
Note: You must dial *565*0# from the same phone number linked to your BVN enrolment. If the number has changed, USSD retrieval will not work, and you would need to contact your bank or the NIBSS BVN helpdesk instead.
Low on airtime to complete a retrieval? You can quickly top up airtime on Gosub before dialing the code.
How to Stop Unwanted Subscriptions Deducting Your Airtime (*305#)
One of the most common complaints among Nigerian mobile users is waking up to find airtime or data deducted for a service they never knowingly subscribed to. These are usually Value-Added Services (VAS), things like ringback tunes, daily jokes, sports alerts, horoscope updates, or "win cash" promos, that get activated on a line without the subscriber's clear knowledge.
The USSD code *305# lets you view and deactivate the value-added services active on your line, and pairing it with the NCC's DND code can stop future unwanted subscriptions too.
See our full guide on how to stop unauthorized airtime deductions in Nigeria using *305# and DND for step-by-step instructions, how to request a refund, and how to escalate to the NCC if needed.
