In this post, you will learn how to master the *737# platform, from basic transfers to advanced security features.

Are you ready? Let us jump right in and look at why this simple code is often better than a high-tech app.
What is the GTBank USSD Code and How Does it Work?
The GTBank USSD code is a dedicated gateway that uses Unstructured Supplementary Service Data to connect your mobile phone directly to the bank’s server. Unlike mobile apps that require internet protocols, USSD uses the same signal your phone uses to make calls or send text messages. This means you can bank from the most remote village in Nigeria as long as you have a basic network signal.
Think of it as a conversation between your phone and the bank. You send a request like *737#, and the bank sends back a menu of options. It is fast, secure, and works on feature phones often called torchlight phones just as well as it works on the latest iPhone.
Who is eligible to use GTB 737 services?
To use this service, you must have an active GTBank account and a mobile number registered with the bank. This mobile number acts as your unique identity. If you have a NUBAN (Nigeria Unified Bank Account Number) and your BVN linked, you are already halfway there.
Note: You cannot use a phone number that is not linked to your account for transactions. This is a vital security layer to prevent unauthorized access to your funds.
Where can you use the code?
You can use the GTBank USSD code anywhere in Nigeria where there is a GSM network signal. It is currently supported by all major telecommunications providers including MTN, Airtel, Glo, and 9mobile. Whether you are in a bustling city like Lagos or a rural area with poor 3G coverage, 737 remains reliable.
According to reports from Nigerian telco users, USSD uptime remains significantly higher than mobile data uptime in rural regions. This reliability is why over 10 million Nigerians rely on USSD for daily transactions.
Why does USSD work without internet or data?
USSD works on a signaling channel rather than a data channel. While an app needs a stable internet connection to “handshake” with a server, USSD sends small packets of data through the voice network. It is essentially a real-time session that stays open while you navigate the menus.
Pro Tip: Because it does not use data, you will never get a connection timed out error due to a slow internet plan. However, sessions usually expire after 20 to 40 seconds of inactivity to keep your account safe.
How to Register and Create Your GTBank 737 PIN
Registering for the GTBank USSD code is a straightforward process that you can complete in less than two minutes. You do not need to visit a physical bank branch to activate this service. All you need is your registered SIM card and your GTBank debit card details for the initial setup.
A 737 PIN is a four-digit secret number that authorizes your transactions. It is different from your ATM PIN, though many people choose to make them the same for easy memory. Here is how you get it done.
How to get started with 737# for the first time?
If you are a first-time user, simply dial *737# on your registered phone number. The system will recognize that you are not yet registered and prompt you to provide the last six digits of your MasterCard or Visa debit card. If you do not have a card, you can still open a GTInstant account by following the prompts for new users.
Example: A new user dials the code, enters their card digits, and is immediately allowed to check their balance. This works because the bank uses your hardware card as proof of ownership before granting mobile access.
How to create a 4-digit transaction PIN via USSD?
Creating your PIN is the most critical step for sending money. Dial *737*5# and follow the on-screen instructions. You will be asked to enter a 4-digit PIN of your choice and then confirm it by entering it a second time. Once successful, this PIN will be required for every transfer or bill payment you make.
- Dial *737*5#.
- Enter the last 6 digits of your Debit Card.
- Type your preferred 4-digit PIN.
- Confirm the PIN and save.
What to do if you need to reset your 737 PIN?
If you forget your PIN, don’t worry. You can reset it by dialing the same *737*5# string. You will need your debit card again to prove your identity. This ensure that even if someone steals your SIM card, they cannot reset your PIN without having your physical ATM card.
Note: According to GTBank security guidelines, for the first 48 hours after a PIN change, your third-party transfer limit may be restricted to ₦125,000 per day as a safety precaution against fraud.
How to Transfer Money Using the GTBank USSD Code
Transferring money is the most popular use of the GTBank USSD code. The system is designed to be extremely fast, with most transactions completing in under 10 seconds. You have two main options: sending money to other GTBank users or sending to other banks in Nigeria.
It is important to double-check the account number before you hit send. While the system will show you the name of the recipient for confirmation, being accurate from the start saves time.
How to send money to another GTBank account?
To send money to a fellow GTBank customer, you use the internal transfer string. Dial *737*1*Amount*AccountNumber#. For example, if you want to send ₦5,000 to account 0123456789, you would dial *737*1*5000*0123456789#. You will then be prompted to enter your 4-digit PIN to authorize the move.
Example: Sending ₦2,000 to a friend. You dial the string, see the name Bolanle Akpan on your screen, confirm it is correct, enter your PIN, and the money moves instantly. This works because intrabank transfers are handled entirely within the GTB ledger.
How to transfer funds to other Nigerian banks?
Sending money to banks like Zenith, UBA, or Access Bank requires a slightly different code. Dial *737*2*Amount*AccountNumber#. After dialing, you will see a list of banks; select the correct one, confirm the recipient’s name, and enter your secret PIN.
Pro Tip: Always wait for the Success message on your screen. If the session ends abruptly without a confirmation, check your balance using *737*6*1# before trying again to avoid double-debiting your account.
What are the transfer limits and charges for 2026?
Banking isn’t free, but GTBank 737 charges are regulated by the Central Bank of Nigeria to ensure they remain affordable. In 2026, the cost of using USSD is split into the network session charge and the bank transfer fee. Most telcos now deduct the ₦6.98 session fee directly from your airtime, while the bank deducts the transfer fee from your account.
| Transaction Amount | Transfer Fee (Other Banks) | Daily Limit |
|---|---|---|
| Below ₦5,000 | ₦10 + VAT | ₦200,000 (PIN only) |
| ₦5,001 – ₦50,000 | ₦25 + VAT | ₦500,000 (With Token) |
| Above ₦50,000 | ₦50 + VAT | ₦1,000,000 (Max Limit) |
Note: To transfer more than ₦500,000 in a single day via USSD, you must use a hardware token for authentication. According to a report by the CBN, these charges are fixed to promote financial inclusion among low-income earners.
Does the ₦6.98 fee bother you, or do you find the convenience worth the small price? Let us look at how you can use the code for more than just sending money.
How to Buy Airtime and Data Packages
Buying airtime or data with the GTBank USSD code is the fastest way to stay connected when you are low on credit. You do not need to look for a physical recharge card vendor or log into an app. The system allows you to top up your own phone or send credit to someone else in seconds. This convenience is a lifesaver during late-night emergencies or when you are in transit.
One thing to keep in mind is the 2026 update regarding charges. While the airtime purchase itself is free of bank commissions, your network provider will deduct a ₦6.98 session fee from your airtime balance. According to a 2025 report from Punch Newspapers, this fee is now deducted directly from your mobile credit rather than your bank account, so ensure you have at least ₦7 in airtime to start the session.
How to top-up your own phone number instantly?
To recharge the phone number linked to your account, simply dial *737*Amount#. For example, if you want ₦1,000 airtime, just dial *737*1000#. The airtime is credited to your line immediately without requiring a PIN for small amounts, making it the most frictionless way to top up.
Example: You are on a call and get the low balance warning. You quickly dial *737*500#, and within 5 seconds, your balance is updated. This works because the bank already trusts the device that is registered to your profile.
How to buy airtime for family and friends?
Sending airtime to a third party requires a slightly longer string: *737*Amount*PhoneNumber#. If you want to send ₦2,000 to a friend, you would dial *737*2000*08012345678#. Unlike self-recharge, this transaction will require you to enter your 4-digit 737 PIN for security reasons.
Pro Tip: There is a daily cumulative limit of ₦10,000 for airtime purchases. If you try to exceed this, the transaction will fail. This limit is designed to protect your account balance in case your phone falls into the wrong hands.
How to purchase mobile data bundles via USSD?
You can also buy data plans directly from your bank balance by dialing *737*4#. This opens a menu where you can choose between self-data or third-party data and select from various bundles offered by MTN, Airtel, Glo, or 9mobile. It is a perfect solution when your data plan expires and you cannot access your banking app to renew it.
- Dial *737*4# on your mobile phone.
- Select 1 for Self or 2 for Third Party.
- Choose your network provider.
- Select the data plan that fits your budget and enter your PIN.
Advanced Features: Loans, Statements, and Cashout
The GTBank USSD code is not just for basic transfers; it is a full-service banking tool. In 2026, you can access credit facilities, generate formal documents, and even withdraw cash from an ATM without using a physical card. These advanced features provide a level of financial flexibility that was previously only available inside a banking hall.
These services often involve higher security checks. For instance, according to GTBank’s official service charter, generating a bank statement or applying for a loan will always require either your 737 PIN or a hardware token code to verify your identity. This ensures that sensitive financial data remains private.
How to apply for GTBank QuickCredit?
If you need an instant loan, you can dial *737*51*51# to access QuickCredit. This service offers up to ₦5 million with a monthly interest rate of approximately 2.5%. The system automatically evaluates your account turnover and history to determine the maximum amount you can borrow in real-time.
Example: A small business owner needs ₦100,000 for urgent stock. By dialing the code, they see an offer for ₦150,000 based on their monthly salary inflows. They accept ₦100,000, enter their PIN, and the funds are deposited into their account within minutes.
How to perform a cardless withdrawal at the ATM?
You can withdraw money without a debit card by dialing *737*3*Amount#. Follow the prompts to generate a withdrawal code. Once you have this code, go to any GTBank ATM, press the Enter key (or select Cardless Withdrawal), enter the code and your 737 PIN to receive your cash. There is usually a ₦50 fee for this convenience.
Note: Cardless withdrawal codes are only valid for a short period, typically 15 to 30 minutes. If you do not use the code within that window, the transaction expires and your money remains safe in your account.
How to generate a 6-month bank statement on your phone?
If you need to show proof of income or track your spending, you can request a mini-statement or a full 6-month statement by dialing *737*51*33#. The statement is usually sent to the email address linked to your GTBank account. It is an efficient way to get documentation for visa applications or business tenders without visiting the branch.
Security First: Protecting Your GTBank Account
While the GTBank USSD code is convenient, security must be your top priority. USSD banking is safe, but it is vulnerable to social engineering and physical phone theft. Understanding the built-in security protocols is the only way to ensure that your hard-earned money remains protected at all times.
The bank will never ask for your PIN or hardware token over the phone or via a text message. If you receive a call from someone claiming to be a bank staff asking for these details, it is a scam. Always remember that your 737 PIN is for your eyes only.
How to use the *737*911# emergency block code?
If your phone is stolen or you notice suspicious activity on your account, dial *737*911# from any phone (it does not have to be your registered number). Follow the prompts to enter the phone number linked to your account and your BVN. This will instantly freeze all transactions on your account across all channels, including USSD, ATM, and the mobile app.
Pro Tip: Memorize the *737*911# code today. In an emergency, every second counts, and being able to block your account immediately can save you from a total loss of funds.
How to identify official GTBank communications?
Official messages from GTBank will typically come from a verified sender ID like GTBank or GTBank737. They will never include links to “update your BVN” on external websites. According to cybersecurity data from the NCC, phishing attacks often use look-alike numbers to trick users into revealing their PINs. Always verify by calling the official help centre at +234 700 4826 66328.
Troubleshooting: Fixing Common 737 USSD Errors
Sometimes, the GTBank USSD code might not work as expected. These errors are usually caused by network congestion, SIM card issues, or system maintenance. Understanding what these error messages mean can save you from unnecessary panic when a transaction does not go through immediately.
Why is my GTBank USSD code showing “Connection Error”?
A Connection Error or Invalid MMI Code message usually means that your mobile network is struggling to communicate with the bank’s server. This is common during peak hours or in areas with poor signal. The best fix is to wait a few minutes and try again, or move to a spot with better reception.
What does “External Application Down” mean?
If you see External Application Down, it means the bank’s USSD gateway is temporarily undergoing maintenance or experiencing a technical glitch. This is not an issue with your phone or your account. In such cases, you should wait for an hour or use the GTWorld app if you have an internet connection available.
Why can’t I receive my 737 PIN or OTP?
If you are not receiving the prompts to enter your PIN or a required One-Time Password (OTP), check if your SIM card is properly inserted and that you are not in Do Not Disturb (DND) mode. Sometimes, telco filters block bank messages. You can try texting ALLOW to 2442 to ensure your number is open to receiving all service messages.
Frequently Asked Questions
How do I check my GTBank account balance?
To check your balance, dial *737*6*1# on your registered phone number. You will be prompted to enter your 4-digit PIN. Once verified, your account balance will be displayed on the screen and also sent to you via SMS. Note that a small fee of ₦10 applies for this enquiry.
Can I use the GTBank USSD code without a debit card?
Yes, you can perform basic tasks like opening an account (dial *737*0#) or checking your balance if you have already set up your PIN. However, for third-party transfers and PIN resets, the system will eventually require you to have a GTBank debit card to authenticate your identity for high-level security.
What is the maximum daily transfer limit for *737#?
The standard daily transfer limit for most users is ₦200,000 using only your transaction PIN. If you need to send up to ₦1,000,000, you must authenticate the transaction using a hardware token. Note that new users or those who recently changed their PIN have a temporary 48-hour limit of ₦125,000.
Does GTBank charge for checking account balance via USSD?
Yes, checking your balance via the GTBank USSD code costs ₦10 per request. This fee is deducted from your bank account balance. This is in addition to the ₦6.98 session fee that your network provider charges from your mobile airtime balance.
How do I link my BVN or NIN using *737#?
To link your Bank Verification Number (BVN), simply dial *737*20*BVN#. For National Identity Number (NIN) linking, you can dial *737*6*5# and follow the prompts. This is a mandatory requirement by the Central Bank of Nigeria to keep your account active and avoid restrictions.
Can I use 737 on a business account?
The *737# platform is primarily designed for Personal Account holders. While business owners can use 737 Merchant Checkout to receive payments, full USSD banking features like loans and high-volume transfers are typically managed through the GAPS platform or the GTBusiness app for corporate entities.
What is the code to deactivate my 737 profile?
If you no longer wish to use USSD banking for security reasons, you can deactivate your profile by dialing *737*911# from any phone and following the prompts to block your specific mobile number from accessing USSD services. To reactivate, you will need to visit a GTBank branch with a valid ID.
