Eleven digits every bank form wants, and not one Nigerian alive knows them by heart.
To check your BVN, dial *565*0# from the phone number linked to your BVN. It works on MTN, Glo, Airtel and 9mobile, costs ₦20, and the eleven digits pop up on your screen within seconds. Screenshot it immediately, because the message is a pop-up, not an SMS, and it vanishes the moment you tap away.*
That is the whole answer for most people. The rest of this post is for when it fails (wrong SIM, a number you lost in 2019, or you are in Manchester and never got a BVN at all), plus a rule from 1 May 2026 about that phone number that you want to know before you next change networks.
What Is a BVN, and Why Does Everyone Keep Asking for It?
Your Bank Verification Number is an 11-digit number tied to your fingerprints and your face, issued once and kept for life. The Central Bank of Nigeria runs the policy and NIBSS (the company that moves money between Nigerian banks) runs the system. Open five accounts in five banks and they all hang off the same BVN.
It does not expire, whatever the WhatsApp broadcast says; the CBN killed the "ten years" rumour in May 2023. And you are in big company: NIBSS data reported by Legit.ng put BVN enrolments at 70,347,047 as at 28 Sep 2026, which is a lot of people who also cannot remember theirs.
How to Check Your BVN With *565*0#
Okay, so, slowly, for the person squinting at this in a banking hall queue:
- Pick up the phone whose SIM carries the number you gave the bank when you registered your BVN.
- Dial *565*0#.
- Wait a few seconds. The BVN shows on screen and ₦20 comes off your airtime.
- Screenshot it, or write it somewhere you will find again (not the back of a receipt you will use to wrap groundnut).
No data, no app, no smartphone even; a torchlight Nokia does the job. If you want the full list of codes for your own bank (balance, transfers, airtime, the lot), we keep them on our bank USSD codes pages, one per bank.
What If *565*0# Doesn’t Work?
Nine times out of ten it is the SIM. The code only answers the phone number registered to your BVN, so a second line, a work phone or your sister's Glo will get you an error, not your digits. Swap SIMs and try again before you try anything else.
The tenth time, it is stranger: NIBSS says no BVN comes back if your phone number is linked to more than one BVN, and that one needs a bank branch. Short of that, there are three other routes:
- Your bank app. Many Nigerian banks show the BVN under Profile or Account Settings.
- Your bank's own USSD code. GTBank, for instance, also answers on *737*6*1#, as listed on our GTBank codes page. Most banks simply point you back to *565*0#.
- A branch. Take a valid ID, go to customer service and ask. It is the slowest route, but it is the only one that also fixes whatever was wrong in the first place.
Can You Check Your BVN Online or by SMS?
Not by SMS: nobody texts you your BVN, which is exactly why the pop-up disappears. Online, your bank's app or internet banking is the safe version. Skip the "free BVN checker" sites that rank for this exact search. You type in your name, date of birth and phone number, and hand a stranger three of the four things a fraudster needs. If the page is not your bank, abeg, close the tab.
Can You Change the Phone Number on Your BVN?
Yes, but only once. From 1 May 2026, the CBN allows a single change to the phone number linked to your BVN, once in your lifetime. The reason is SIM-swap fraud: the number on your BVN is where every OTP and recovery code goes, so whoever controls that number controls a lot.**
So before you visit the branch to update it, pick a number you will keep for decades, ideally the one already tied to your NIN. Not the promo line you bought because data was cheap that month.
How to Get a BVN If You Don’t Have One
In Nigeria, it is free. Walk into any bank branch with a valid ID, fill the enrolment form, give your fingerprints and a photo, and the bank tells you when your number is ready. You need to be 18 or over, which the same 2026 rules now spell out.
From abroad, there is finally a proper route: the Non-Resident BVN (NRBVN) platform, run by NIBSS for the CBN. It lets Nigerians in the diaspora enrol online with a passport, proof of foreign residence and a selfie liveness check instead of fingerprints. Per Nairametrics's walk-through, it costs US$50 and the number comes within 72 hours of approval.
Is It Safe to Share Your BVN?
Your BVN confirms who you are; it does not authorise a transfer. Money moves when someone also has your PIN or the OTP sent to that phone number, which is why a scammer who asks for your BVN always asks for "the code we just sent you" two minutes later.
So give it to a licensed bank or fintech inside their own app, never to a "secure BVN link" that arrived by SMS or WhatsApp, and never read an OTP to anyone who called you first. The 2026 rules also let banks hold a flagged BVN for up to 24 hours while they call the customer, which is annoying when it is you and lovely when it is not.
Why Mular Asks for Your BVN
Mular asks for your BVN for one thing: to give you your own Naira account number, so you can fund your Naira wallet by bank transfer. Everything else works without it. You can swap crypto to Naira and back, send Naira from your wallet, and receive money from another Mular user before you have entered a single digit. So if *565*0# is sulking today, you can still pay somebody from your USDT balance and come back to the BVN when the SIM turns up.
The Number Was Never the Secret
People guard the BVN like a PIN and treat the phone number as an afterthought, when it is really the other way round. The eleven digits are an ID card; the phone number is the doorbell every bank rings when something happens to your money, and as of this year you get to move that doorbell exactly once. So check your BVN, screenshot it, then make sure the number it answers to is one you plan to keep. Future you, in a banking hall with a dead SIM, will be grateful.
Verify Once, Then Spend From One App
On Mular your BVN does one job, opening your Naira account number, and after that you are paying bank accounts straight from your Naira, USD or crypto balance in about ten seconds. Check what your Dollars are worth on the USD to Naira page while you are at it.
Download Mular and get verified in one go.
As always, stay Jiggy.
Love, Mr Mular.
* The *565*0# code, the ₦20 charge and the "one phone number, more than one BVN" exception are from NIBSS's USSD validation page, read 20 Oct 2026: https://nibss-plc.com.ng/ussd-validation-services/
** The once-in-a-lifetime phone number change, the 24-hour watchlist and the 18-and-over enrolment rule took effect 1 May 2026, per NIBSS's explainer of the CBN's new BVN regulation: https://nibss-plc.com.ng/what-cbns-new-bvn-regulation-mean-for-the-nigerian-financial-ecosystem/
Rewritten because the old version predated the 2026 rules and had nothing to say to anyone reading from outside Nigeria.
