How To Change BVN Phone Number in Nigeria

To change your BVN phone number, you must visit a branch of your bank in person with a valid ID, your BVN, and proof of the new number. You cannot change your BVN phone number online, by app, or over the phone. Since 1 May 2026, the Central Bank of Nigeria (CBN) allows you to change the phone number on your BVN only once in your lifetime, so the number you switch to should be one you intend to keep permanently. check your BVN on Access Bank

Important: The CBN BVN Phone Number Update Now Once-in-a-Lifetime Rule

This is the single most important thing to know before you start.

In a circular issued to banks on 13 March 2026 and effective from 1 May 2026, the CBN restricted BVN phone number updates to once in a lifetime. The rule applies across every bank, fintech, microfinance bank and mobile money operator in Nigeria, and affects all BVN holders. NIBSS recorded BVN enrolment at 68.59 million as of March 2026.

What this means for you in practice:

• If you have never changed your BVN phone number, you have one change available. Use it carefully.
• Once you use it, the number is locked. Any further change requires exceptional regulatory approval, involving extensive documentation and verification.
• Choose a number you control personally and intend to keep for years. Do not use a work line, a borrowed phone, or a number tied to a network you plan to leave.
• Before you change anything, confirm the new SIM is registered in your own name and is active.

Why the CBN did this. The linked phone number is used for one-time passwords (OTPs), transaction alerts and account recovery, which makes it the main target in SIM-swap fraud. A fraudster swaps your SIM, requests a BVN phone number change, then resets your banking credentials and drains the account. NIBSS recorded 62,901 fraud cases linked to social engineering schemes in 2023, many involving compromised phone numbers. Capping changes closes that route.

Other BVN changes that took effect alongside it. The CBN also directed banks to operate a temporary watchlist, where a BVN linked to suspicious activity can be flagged for up to 24 hours while the bank contacts you to verify a transaction. BVN enrolment is also restricted to individuals aged 18 and above.

Can You Change Your BVN Phone Number Online?

No. There is no official online portal, mobile app, or USSD code that lets you change your BVN phone number online. Any website or app claiming to do it is not legitimate, and you should not enter your BVN or bank details there.

The change must be done in person at a bank branch. This is deliberate, for four reasons:

1. Identity verification: 

The bank must confirm the person requesting the change is the actual BVN holder, which requires physical ID checks and often biometric confirmation.

2. Fraud prevention:

An online change route would be exactly the weakness SIM-swap fraudsters exploit. In-person verification removes it.

3. Regulatory compliance.

Nigerian banks must meet CBN requirements on customer identification and fraud prevention, and in-person verification is how they evidence it.

4. Data protection:

 Your BVN links to every bank account you hold. Requiring physical presence limits unauthorised access to that record.

Many people ask how to change a BVN phone number without going to the bank. There is currently no legitimate way to do this. If your bank offers to start the request through its app or customer service line, you will still be required to complete it at a branch.

Can You Change Your BVN Number Itself?

No, and this is a different question worth separating clearly. People often ask can BVN be changed, or how to change my BVN number, when what they actually need is a phone number update.

Your BVN number is permanent. The 11-digit BVN issued when you enrolled cannot be changed, replaced, renewed or reissued. It is your identifier across every bank in Nigeria for life.

You cannot have two BVNs. Enrolling more than once is not permitted, and duplicate BVNs are flagged and merged or deactivated. If you believe you have two, report it to your bank rather than using both.

What you can change is the information attached to your BVN, such as your phone number, name, or date of birth, subject to the rules and limits below.

So, to answer directly: can I change my BVN number? No. Can I change my BVN phone number? Yes, once in a lifetime.

BVN Update Process: What You Can and Cannot Update

The BVN update process and BVN modification cover several different requests, and they follow different rules. This table sets out what is possible.

Is there a BVN self-service portal or app?

 No. There is no NIBSS or CBN BVN portal, app, or website that lets you modify your BVN details yourself. NIBSS operates the NIBSS BVN validation portal infrastructure for banks, not a public modification service. Any app or website offering BVN self-service modification is not legitimate, and entering your BVN there puts your bank accounts at risk.

Every BVN modification runs through a licensed bank, in person, with identity verification. If you are told otherwise by a message, social media post, or someone offering to do it for a fee, treat it as fraud.

What "modify your BVN" means when your bank asks. If a bank prompts you to modify or update your BVN, it usually means the details on your BVN record no longer match the details on your bank account, most often the phone number. Banks require these to match before granting mobile banking access. Resolving it means visiting a branch to align the two records.

What You Need to Change or Update Your BVN Phone Number

If you are wondering what do I need to change my BVN phone number, bring all of the following to the branch. Missing one item is the most common reason people are turned away and have to return.

• A valid government-issued ID. An international passport, driver's licence, National ID card (NIN slip or card), or voter's card.
• Your BVN. Bring your BVN acknowledgement slip if you still have it. If not, you can retrieve your BVN by dialling 5650# from the phone currently linked to it.
• The new SIM card, active and in your name. Some banks ask for proof of ownership, such as the SIM pack or a printout from your network showing the number is registered to you.
• Your account details for the bank where you are making the request.
• The old phone number if you still have access to it, since some banks send a confirmation OTP to the existing number as part of verification.

You will complete a BVN update or change request form at the branch, and you may be asked to redo biometric capture, meaning fingerprints and a photograph, to authenticate the change against your BVN record.

How to Change Your BVN Phone Number: Step by Step

Follow these steps in order to change the phone number on your BVN.

1. Confirm you have not already used your one change. If you have changed your BVN phone number before, ask your bank whether a further change is possible before making the trip.
2. Register and activate the new SIM in your own name. Complete NIN-SIM linkage with your network first, since a number not registered to you will fail verification.
3. Visit a branch of your bank in person. Go to the bank where you hold your primary account. Some banks require the branch where your BVN was originally enrolled, so call ahead to confirm.
4. Request the BVN update or change request form at the customer service or BVN desk.
5. Complete the form accurately, entering your BVN, your current registered number, and the new number exactly.
6. Submit your ID and supporting documents, including proof of ownership of the new number if requested.
7. Complete biometric verification if the bank requires it, usually fingerprints and a photograph.
8. Collect your acknowledgement or reference for the request before leaving, so you can follow up.
9. Confirm the update has gone through after a few working days by checking that OTPs and transaction alerts arrive on the new number.

How to Link a New Phone Number to Your BVN

Linking a new number to your BVN and changing your BVN phone number are the same process. There is no separate procedure: whether you search how to link my BVN to my new number or how to change it, the bank updates the single phone number field on your BVN record, replacing the old number with the new one.

This matters because your BVN holds one phone number, not several. You cannot link two numbers to one BVN, and you cannot add a second number while keeping the first. Linking a new number means replacing the existing one, which is why it counts against the CBN's once-in-a-lifetime limit.

To link your new number to your BVN:

1. Register and activate the new SIM in your own name, completing NIN-SIM linkage with your network.
2. Visit your bank branch in person with a valid ID and your BVN.
3. Request the BVN update form and enter the new number you want linked.
4. Complete identity and biometric verification.
5. Confirm after a few working days that OTPs and alerts now arrive on the new number.

One point often confused: linking your BVN to a bank account is a different task entirely, and that one can be done remotely. Most banks let you link an existing BVN to an account by USSD, such as GTBank's 73720*BVN#, or through internet banking. That process attaches your BVN to an account. It does not change the phone number stored on the BVN itself, which still requires a branch visit.

How Long Does It Take to Change or Update a BVN Phone Number?

How long it takes to change a BVN phone number depends on your bank. Most complete the update within a few working days of a correctly submitted request, and some process it within 24 to 48 hours. Timing depends on internal verification and how quickly the change reflects in the NIBSS BVN database.

If OTPs and alerts are still going to your old number after about five working days, return to the branch with your acknowledgement slip and ask them to confirm the update was submitted and reflected.

Can I Change My BVN Phone Number at Any Bank?

Not necessarily. Many people ask can I change my BVN phone number in any bank, and the safest answer is to go to the bank where you hold your primary account, ideally the bank where your BVN was originally enrolled.

Because your BVN is shared across all Nigerian banks, an update made by one bank updates the central NIBSS record. However, individual banks set their own internal rules about which branches can process BVN modifications, and some will only handle it where the BVN was enrolled or where you hold an active account. Call your bank's customer service line before travelling to a branch.

How to Change Your BVN Phone Number at GTBank, First Bank, UBA and Other Banks

Whether you are searching how to change my BVN phone number online GTB, First Bank, or UBA, the process is broadly identical at every Nigerian bank, because the rules are set by the CBN and NIBSS rather than by individual banks. In every case the change is made in person at a branch, using a BVN update form, valid ID, and biometric verification where required. No major Nigerian bank offers a fully online BVN phone number change.

What differs between banks is only the practical detail: which branches process BVN modifications, whether they require the branch of original enrolment, and what proof of new-number ownership they ask for. GTBank, for example, directs customers to visit a branch to update a registered phone number.

The reliable step is to call your bank's official customer service line first and confirm the branch and documents before you travel. Use the number printed on your debit card or on the bank's official website, never a number from a social media post or WhatsApp message.

What If You No Longer Have Access to Your Old Number?

If you lost the SIM linked to your BVN, this is now a more serious problem than it used to be, because of the once-in-a-lifetime cap.

Your first step is to try to recover the same number from your network operator. Most Nigerian networks will reissue a SIM with your existing number if you visit their office with the ID used to register it. Recovering the original number avoids using up your single BVN change entirely.

Only if the number is genuinely unrecoverable should you use your one lifetime change. In that case, take your ID and a police report if the phone was stolen, and explain the situation at your bank branch. Because you will be verified without an OTP to your old number, expect stricter identity checks, including biometrics.

How to Change the Name or Date of Birth on Your BVN

Yes, you can. How to change your BVN name and how to change your BVN date of birth are a separate process from a phone number change, known as BVN modification, and both are handled in person at a bank branch.

For a BVN name change or correction, bring supporting evidence of the correct name, such as a birth certificate, sworn affidavit, marriage certificate for a change of surname, or newspaper publication where required. Banks will not amend a name without documentary proof.

For a BVN date of birth correction, banks apply strict limits, because date of birth is a core identity field used in verification. Bring your birth certificate or age declaration and a valid ID. Expect the request to be reviewed rather than processed on the spot, and be aware that repeated date of birth changes are not permitted.

In both cases you complete a BVN modification form at the branch and may need to redo biometric capture. Processing usually takes longer than a phone number change, since the request is reviewed against your submitted evidence.

How to Check Which Phone Number Is Linked to Your BVN

Before changing anything, confirm which number is currently on your BVN record. This answers how to know the number linked to my BVN.

Dial *565*0# from the phone number you believe is linked. If the BVN is returned, that number is the one on file. If nothing comes back, that is not the registered number.

You can also ask at your bank branch, or check within your bank's mobile app profile section where your registered contact details are displayed. Never use third-party websites or apps that ask for your BVN to check your details, as these are a common phishing route.

Protect Yourself From BVN Fraud

Your BVN is the backbone of your banking identity, and fraudsters know it.

• Never share your BVN with anyone who contacts you unsolicited. Legitimate banks do not call and ask for it.
• No one should charge you to change your BVN phone number. The process at your bank does not require paying an agent.
• Ignore "BVN update" links sent by SMS, WhatsApp, or social media. There is no legitimate online BVN modification portal.
• Report a lost SIM immediately to both your network and your bank, since a SIM swap is the first step in most account takeovers.
• Keep your registered number active. A number deactivated for long inactivity can be recycled to another user, which creates a serious security exposure on your bank accounts.

BVN Verification for Businesses

For banks, fintechs and other regulated businesses, the CBN's tightening of BVN rules raises the bar on customer verification. A phone number that no longer belongs to the customer, or a BVN record that does not match the person presenting it, is exactly the gap fraudsters exploit during onboarding.

Youverify provides BVN verification and identity verification built for Nigeria and the wider African market, letting compliance teams confirm in real time that a BVN is valid, that it belongs to the customer presenting it, and that the associated details match official records. This supports KYC and AML obligations while keeping onboarding fast.
