What is ASBA?
ASBA (Application Supported by Blocked Amount) is a process in which the application amount is blocked in the investor's bank account rather than transferred immediately to the issuer. If shares are allotted, the applicable amount is debited; if no allotment is made or the allotment is lower than the bid amount, the relevant amount is unblocked in accordance with the process.
Applying step by step
Use an eligible bank, broker or application channel permitted for the issue.
Enter the correct PAN, demat details, bid quantity, price and investor category.
Where applying through UPI, enter a valid UPI ID belonging to the applicant and approve the mandate in the UPI app within the prescribed time.
Check that the mandate amount and application details match your intended bid.
Keep the application number and acknowledgement for reference.
Track application, mandate, allotment and refund/unblocking status through official channels.
Keep your credentials safe
Do not share your UPI PIN, OTP, password or remote-access credentials with anyone. A legitimate IPO application does not require you to disclose these secrets to a support executive.
