How to Link Your NIN and BVN to Your Nigerian Bank Account: A Step-by-Step Guide

In a major move to strengthen the Nigerian financial system, the Central Bank of Nigeria (CBN) has mandated that all bank accounts—from Tier 1 wallets to Tier 3 corporate accounts—must be linked to both a Bank Verification Number (BVN) and a National Identification Number (NIN). Accounts that fail to comply face a "Post No Debit" (PND) status, meaning you will be unable to withdraw funds or perform outgoing transactions. This guide provides the quickest ways to complete your linkage without the stress of long bank queues.

Why You Must Link Your NIN and BVN Immediately

The goal of this policy is to enhance the Know Your Customer (KYC) procedures across all financial institutions in Nigeria. By linking these two unique identifiers, the government aims to curb electronic fraud, money laundering, and identity theft. For the everyday user in Lagos, Abuja, or Owerri, this linkage ensures your account remains active and provides an extra layer of biometric security for your hard-earned money.

Option 1: Using USSD Codes (The Fastest Way)

Most Nigerian banks have simplified the process through USSD codes, allowing you to link your details directly from your registered mobile phone. Here are the most common codes:

• GTBank: Dial *737*20*BVN# and follow the prompts.
• Zenith Bank: Dial *966*NIN# and follow the instructions.
• Access Bank: Dial *901*11# and input your NIN and BVN when prompted.
• First Bank: Dial *894*NIN# (replace "NIN" with your 11-digit number).
• UBA: Interact with "Leo," UBA’s virtual assistant, on WhatsApp or Facebook, or dial *919*NIN#.

Option 2: Using Bank Self-Service Portals

If you prefer an online approach, almost every Nigerian bank has a dedicated NIN/BVN Linkage portal on their official website.

1. Visit your bank's website (e.g., www.gtbank.com or www.accessbankplc.com).
2. Look for the "NIN Update" or "BVN Linkage" button on the homepage.
3. Enter your account details and follow the verification steps, which usually include a One-Time Password (OTP) sent to your registered phone number.
4. Input your 11-digit NIN and 10-digit BVN, and upload a clear photo of your NIN slip if required.

Option 3: Visiting the Bank Branch

For those who encounter errors with digital platforms, visiting a physical branch remains the most reliable option. You will need to:

• Carry your original NIN slip or National ID card.
• Fill out a simple "Update Form" at the customer service desk.
• Ensure that the name and date of birth on your NIN exactly match the records on your BVN to avoid a data mismatch, which is a leading cause of linkage failure.

Pro-Tip: Managing Changes

As of May 2026, the CBN has introduced a new safeguard where the phone number linked to your BVN can only be changed once in a lifetime. This makes it critical to use a permanent, active phone number for all your biometric registrations to avoid future complications.
