Need a Quick Way to Link Your Bank Accounts to UPI?
Enjoy an instant, 100% digital way to bring your bank accounts onto UPI. Linking works off the
mobile number registered with your bank: once that number is verified on your device, your eligible
accounts are fetched automatically, so there is no account number or IFSC to type in and nothing to
upload.
Stashfin supports a multi-bank profile, so you can keep several accounts linked at once, mark one as
primary, and choose the funding source on any individual payment. Each linked account carries its
own UPI PIN, which means the accounts stay independent of one another.
Linking Operations & Requirements
| Operation / Feature | Requirement | How It Works |
|---|---|---|
| Link a Bank Account | Mobile number registered with that bank, active on the device | Open UPI settings -> Add bank account -> Pick your bank -> Eligible accounts are fetched automatically -> Confirm |
| Automated Account Fetch | SIM-based mobile number verification | Accounts are pulled from the bank against your registered number — no account number or IFSC entry |
| Set UPI PIN on the Account | Debit card or verification details for that account | Verify card credentials -> Enter the bank OTP -> Create and confirm the UPI PIN |
| Set Primary Account | At least two linked accounts | Select the account -> Mark as primary. New payments default to it. |
| Multi-Bank Profile | Same mobile number registered with each bank | Link several accounts and switch the funding source per payment |
| De-link an Account | The account is currently linked | Select the account -> Remove -> Confirm. The account's UPI PIN is retired with it. |
Features and Benefits of Bank Account Linking via Stashfin
Linking is the step everything else on UPI depends on, so it should take seconds and never ask you
for a document.
Instant Linking via Mobile Number:
Your identity is established by the mobile number registered with your bank, verified against the
SIM in your device. No form, no branch visit.
Automated Account Fetch:
Eligible accounts are pulled from the bank automatically, so there is no account number or IFSC to
type and no transcription error to fix.
Multi-Bank Profile Setup:
Keep several accounts from different banks linked at the same time and pick which one funds a given
payment.
Independent PIN Per Account:
Every linked account has its own UPI PIN, so one account's credentials never unlock another.
Primary Account Control:
Mark the account you use most as primary and new payments default to it, without losing the ability
to switch.
Zero Linking Charges:
Adding, switching or removing a linked account carries no fee.
A newly linked account may carry a reduced transaction limit for a short period, set by your bank —
check the limit that applies before making a large first transfer from it.
