AU Small Finance Bank is a scheduled commercial bank that provides savings and current accounts, deposits, cards, loans and a wide range of digital banking services. For customers who only need to know the available balance or check a few recent transactions, the bank provides simple phone-based options that do not require opening the mobile banking app or NetBanking.
The most direct option is AU Small Finance Bank’s official missed-call banking service. Customers can check their account balance by giving a missed call to 1800-120-2586 and can request the mini statement or last five transactions through 1800-121-2586. The call should be made from the Indian mobile number registered with the bank. AU also provides AU 0101 Mobile Banking and NetBanking, WhatsApp Banking, ATM and branch-based options for customers who want other ways to view account information.

AU Small Finance Bank Balance Check Through Missed Call
AU Small Finance Bank provides a dedicated toll-free missed-call number for account balance enquiry. The official balance check number is:
1800-120-2586
Give a missed call to this number from the mobile number registered with your AU Small Finance Bank account. The call disconnects automatically and the bank sends the balance information to the registered mobile number by SMS. Internet access or a smartphone is not required for this facility.
The bank states that the registered mobile number must be linked with the account for balance enquiry. If the mobile number has changed or is not registered correctly, the missed-call service may not return the expected account information.
Steps to Check AU Bank Balance by Missed Call
- Use the Indian mobile number registered with your AU Small Finance Bank account.
- Dial 1800-120-2586.
- Give a missed call and allow it to disconnect automatically.
- Wait for the SMS response from the bank.
- Read the message to view the account balance.
AU Small Finance Bank Mini Statement Missed Call Number
Customers who want to check recent transactions can use AU Small Finance Bank’s separate missed-call number for the mini statement. The official number is:
1800-121-2586
A missed call to this number from the registered mobile number can be used to receive details of the last five transactions. According to the bank, this facility works when one eligible account is linked to the registered mobile number for the mini-statement request.
AU Small Finance Bank SMS Balance Enquiry
AU Small Finance Bank’s missed-call service sends the requested account information by SMS after the customer calls from the registered mobile number. However, the bank’s current public missed-call banking page does not publish a separate BAL-type SMS keyword and destination number for checking the account balance.
Customers should therefore avoid using SMS commands copied from unofficial or old third-party pages unless the command is confirmed directly by AU Small Finance Bank. For a verified phone-based balance enquiry, use 1800-120-2586. For the last five transactions, use 1800-121-2586.
Check AU Small Finance Bank Balance Through WhatsApp Banking
AU Small Finance Bank also provides WhatsApp Banking on 8383838399. Save the number and send “Hi” from the mobile number registered with the bank to start the service.
The bank lists Account Balance, Account Statement and Last 5 Transactions among the account services available through WhatsApp. Customers can select the required option from the chat menu after completing the bank’s verification process.
Do not share an ATM PIN, CVV, UPI PIN, NetBanking password or other confidential banking credentials in a WhatsApp chat. AU states that customers are not required to provide confidential PINs or passwords for using its WhatsApp Banking service.
AU Small Finance Bank Customer Care Number
For help with balance enquiry, mobile registration or NetBanking, customers can use AU Small Finance Bank’s official support channels.
Customer Care Toll-Free Number: 1800-1200-1200
Customer Care Email: customercare@aubank.in
If the missed-call service does not work, customer care or the nearest branch can help verify the registered mobile number and account status.
Check AU Small Finance Bank Balance Through AU 0101 App
Customers can also view balance and transactions through the AU 0101 Mobile Banking App, along with statements, fund transfers, card management and cheque services.
After logging in, open the Accounts section on the home page to view the balance of linked savings or current accounts. Customers registering the app should use the SIM containing the mobile number registered with the bank because device binding and verification may use that number.
Check AU Small Finance Bank Balance Through NetBanking
AU 0101 NetBanking is another 24×7 option. After logging in through the official website, open the Accounts module to view the balance of linked savings or current accounts.
Always open NetBanking through the bank’s official website or saved trusted login page. Avoid entering Customer ID, password, OTP or card details on links received through unknown messages, emails or social-media posts.
Check AU Small Finance Bank Balance at an ATM
AU Small Finance Bank debit-card customers can check their account balance at an ATM. Insert the debit card, enter the ATM PIN and select the Balance Enquiry option. Where available, the Mini Statement option can also be used to review recent transactions.
Cover the keypad while entering the PIN and do not allow an unknown person to handle the card. Any ATM charges, if applicable, depend on the account type, ATM used and the bank’s current schedule of charges.
Check AU Small Finance Bank Balance Through Branch or Account Statement
Customers who prefer an offline option can visit an AU Small Finance Bank branch or obtain an account statement. A statement gives a detailed record of posted credits and debits when more information is needed than a simple balance enquiry.
