Know Your Bank

Fraudsters often pretend to be HDFC Bank officials on calls or copy bank communication. Hence, HDFC Bank makes it easy for you to check whether a call, message, or link is genuinely from us.

Always verify before you respond. Look for these Trust Markers:

Calls: HDFC Bank Calls begin with 1600 & 140 number series
SMS: Only comes from HDFCBK / HDFCBN
Links: All short links use https://1.hdfc.bank.in/xxxxxx
Domains: Only www.hdfc.bank.in and official emails from name@hdfc.bank.in

If the call or SMS comes from any other number or sender ID, it is not HDFC Bank.
