Bank account linking in demat opening: the penny drop explained

During demat account opening, customers add a bank account. Many brokers verify it instantly using a small test credit known as a penny drop. When it works, customers barely notice. When it fails, the application stops. Here is what you need to know.

What a penny drop is

The broker sends a very small amount (often ₹1) to the bank account entered. The bank's response confirms that the account exists and returns the account holder's name. The broker then matches this name with the applicant's name.

Why it matters

Money from selling shares will be paid into this bank account. Verifying it protects the customer from typos and protects the system from people linking someone else's account.

Common reasons it fails

• Wrong account number or IFSC: one wrong digit is enough.
• Name mismatch: the bank's name for the account does not match the applicant's name closely enough.
• Inactive or dormant account: the bank rejects the credit.
• Account type restrictions: some accounts, like certain loan or restricted accounts, may not accept credits.
• Bank server delays: occasionally, the bank does not respond in time.

How to fix each problem

Wrong details

Copy the account number and IFSC from the bank app or cheque book. Avoid typing from memory.

Name mismatch

If the bank account name differs from PAN, the customer may need to update their bank KYC name. Some brokers allow a manual check by uploading a bank statement or cancelled cheque.

Dormant account

The customer should reactivate the account with their bank, usually by doing a transaction or completing KYC.

Server delays

Wait and try again later, or use the broker's alternative verification option.

Alternative verification

If the penny drop fails, many brokers let customers upload a bank statement, a cancelled cheque or a passbook front page. This may take longer because it is checked manually.

Which bank account is best?

The customer's primary savings account, in their own name, where they are the first holder, is usually best. It is also convenient for receiving sale proceeds and dividends.

Can the bank account be changed later?

Yes. Most brokers allow customers to add or change linked bank accounts through a verification process. So if the customer opens a new account later, they can update it.

Privacy reminder

Bank details are sensitive. Customers must enter them directly on the broker's page. As a referral partner, never ask customers to send you their bank details, cheque photos or statements.

A helpful pre-check

Before sharing your link, mention: "Keep your bank app open so you can copy your account number and IFSC exactly. The name on the bank account should match your PAN."

Why this improves your results

Many half-finished applications stop at the bank step. A simple preparation message reduces those drop-offs. Combined with the documents checklist and an Aadhaar mobile check, you remove most of the obstacles customers face.

Summary

The penny drop is a quick, automatic check of the customer's bank account. It fails mainly because of typos, name mismatches or inactive accounts. With a little preparation, customers pass it easily and complete their application in one go.

Key points to remember

• The penny drop is a small test credit that confirms the bank account.
• Most failures come from typos, name mismatches or dormant accounts.
• Copy details from the bank app instead of typing from memory.
• Manual verification with a statement or cheque is usually available as a backup.
• The linked bank account can typically be changed later through the broker.
• Customers should enter bank details themselves; never collect them.
