Whether you’re a fintech startup, a loan aggregator, an HRMS platform, or an e-commerce company managing seller payments — you need a reliable, secure, and real-time solution for bank account verification.
That’s exactly what 7uniqueverify delivers.
This blog is your complete guide to Bank Account Verification APIs offered by 7uniqueverify — including how they work, when to use them, and why they matter for Indian businesses.
Why Bank Account Verification Is Critical Today
Imagine you’re sending a ₹50,000 payout to a vendor — and the bank details they gave are incorrect. The payment bounces, your team wastes hours figuring it out, and the vendor loses trust. In other scenarios, you could end up transferring money to the wrong person — resulting in major financial loss or fraud.
Bank account verification helps you avoid all that.
It enables your system to validate if the account exists, matches the right person, and is active — before releasing the payment. For businesses, this means:
- Fewer transaction failures
- Protection against fraud
- Faster onboarding
- Regulatory compliance (RBI, KYC/AML)
- Better customer satisfaction
Let’s now understand how 7uniqueverify helps achieve this through 4 powerful verification APIs.
Introducing 7uniqueverify – India’s Trusted Verification Platform
7uniqueverify is a product of Sevenunique Tech Solutions Pvt. Ltd. offering a full stack of identity verification APIs — including Aadhaar, PAN, Voter ID, copyright, Crime Check, and more.
The Bank Account Verification API is one of its flagship offerings. It provides multiple verification options:

- Mobile to UPI Fetch
All APIs are built for real-time validation, easy integration, and support for all major Indian banks.
Let’s now go into detail.
Types of Bank Account Verification APIs by 7uniqueverify
| Verification Method | Purpose | Ideal For |
| Penny Drop | Traditional method with ₹1 transfer | High-value payouts, lending, salary disbursement |
| Penny-Less | Silent background check | Bulk KYC, fintech onboarding, cost-efficient flows |
| UPI/VPA | UPI ID validation | UPI apps, wallets, digital payments |
| Mobile to UPI | Discover UPI IDs via mobile | Mobile-based onboarding, eKYC |
1. Penny Drop Verification – Bank-Confirmed & Trusted
How it works:
A small amount (usually ₹1) is sent to the provided bank account via NEFT/IMPS. The bank’s system confirms whether the account is active and provides the name of the account holder from the transaction metadata.
Why use it?
- Verifies account validity + ownership
- Offers proof of transaction
- Works across all major Indian banks
Best suited for:
- Loan disbursals (NBFCs, banks)
- Vendor payouts
- Salary disbursement in HRMS tools
Key Points:
- Very accurate
- Takes 2–5 seconds
- Cost: ₹2–₹3 per verification
Example Use Case:
A fintech lending platform wants to ensure that the borrower’s bank account matches the PAN and Aadhaar submitted during onboarding. Penny Drop offers the most reliable check.
2. Penny-Less Verification—Fast & Cost-Efficient
How it works:
This API verifies the account number and IFSC using secure backend systems like NSDL or Yes Bank. No money is transferred. It checks the existence of the account and returns the name of the account holder silently.
Why use it?
- Ideal for bulk verifications
- No fund transfer = zero disturbance
- Cheaper and faster than Penny Drop
Best suited for:
- Fintech apps verifying thousands of users
- eKYC onboarding
- Loan marketplaces
Key Points:
- Takes 1–2 seconds
- Cost: ₹0.50–₹1 per verification
- No transaction proof, but reliable for pre-verification
Example Use Case:
A credit card app offering pre-approved offers wants to verify 10,000 accounts daily. Penny-Less saves money and time with silent background checks.
3. UPI/VPA Verification – Validate UPI Handles
How it works:
The API validates a user’s UPI ID (Virtual Payment Address) such as raj@okaxis. It confirms whether the UPI ID is valid and fetches the name of the linked account holder.
Why use it?
- UPI is India’s most-used payment method
- No need to collect bank account details
- Helps prevent wrong UPI transactions
Best suited for:
- Wallets & UPI-based platforms
- UPI cashbacks, rewards, and instant refunds
- Apps offering scan & pay features
Key Points:
- 1–3 second response time
- ₹1–₹2 per verification
- Great for mobile-first users
Example Use Case:
A subscription-based OTT platform uses UPI for monthly auto-debit. Before activating auto-debit, the UPI handle is verified using this API.
- Mobile to UPI Fetch – Smart UPI Discovery
How it works:
This API checks a mobile number and fetches all UPI IDs linked to it. It helps discover available payment methods for a user using just their phone number.
Why use it?
- Onboards users who don’t know their UPI
- Can suggest default UPI handles for transactions
- Verifies mobile + UPI linkage
Best suited for:
- Wallets, neobanks, and salary apps
- Onboarding users in tier 2 & 3 cities
- Payment discovery during registration
Key Points:
- 2–4 seconds
- ₹1.50–₹2.50 per request
- Returns multiple VPAs (UPI handles)
Example Use Case:
An edtech app collecting fees via UPI verifies the parent’s mobile number and fetches all available UPI handles, so the parent doesn’t need to input them manually.
