HDFC Bank has scheduled maintenance activities on May 9 and 10, 2025, during the early morning hours. Important digital services, including UPI and net banking, including mobile banking, will be temporarily disabled. This downtime is part of an extensive system upgrade as a result of HDFC Bank’s merger with HDFC Ltd.

This article is based on the information stated by credible reports published by Goodreturns, The Economic Times, The Times of India, The Free Press Journal, MSN, and HDFC Bank's official website.

Think of it like this:

Kavita, a freelance graphic designer based in Mumbai, had ₹12,500 outstanding from a client. The client attempted to pay her using HDFC UPI on the morning of May 9, but it did not work. She then attempted to transfer it via NetBanking—same result.

Since her rent payment was due that night and she only had ₹800 in her e-wallet, Kavita had to scramble, borrowing eventually from a friend to avoid paying a late charge.

It's not simply a matter of late payments—it's about getting caught off guard.

Here's a step-by-step breakdown of the scheduled HDFC Bank maintenance and how you can be one step ahead.

Why Is HDFC Bank Going Offline for 2 Days?

Think of it as a full-body service for your car—frustrating at the time, but worth it for smoother rides ahead.

HDFC Bank has announced a scheduled maintenance on May 9 and 10, 2025, early in the morning. This is part of a big core banking upgrade post-merger with HDFC Ltd.

The Objective?

Faster online services
Improved system performance
Fewer downtimes in the future

Yes, it's inconvenient. But the bank assures you that it's all worth it to improve your online banking experience in the long term.

Full Downtime Schedule: Critical Hours to Avoid

The downtime will be done in two stages, impacting customers primarily during the early morning. The bank has requested users to avoid making time-sensitive transactions during these periods to avoid inconvenience.

The following are the details you should be aware of:

Date	Time (IST)	Duration	Notes
May 9, 2025	12:30 AM – 4:00 AM	1.5 hours	E-commerce transactions using HDFC Bank debit/credit cards are unavailable
May 9, 2025	01:00 AM – 04:00 AM	3 hours	Credit card transactions & statement access are unavailable
May 10, 2025	02:30 AM – 05:30 AM	3 hours	NetBanking, mobile banking (UPI, IMPS, NEFT, RTGS), merchant payments, and instant account opening services disrupted
	04:30 AM – 06:30 AM	2 hours	Loan services temporarily halted
	05:00 AM – 07:00 AM	2 hours	Credit card services are temporarily unavailable
	05:00 AM – 07:00 AM	2 hours	Demat services temporarily unavailable

For customers who depend on HDFC Bank's digital platforms for financial transactions, planning is essential to avoid delays in payments and transfers.

Services Unavailable During the Maintenance Time

During maintenance time, from May 9 to May 10, 2025, some of HDFC Bank's important digital services will be unavailable temporarily.

Customers are requested to note the unavailable services:

UPI Transactions	Sending and receiving money through UPI is disabled during the maintenance time.
HDFC NetBanking	Both Corporate and Personal clients' NetBanking will be out of operation.
HDFC Mobile Banking Application	The application is likely to be down momentarily.
IMPS & NEFT Transfer	Immediate Payment Service (IMPS) and National Electronic Funds Transfer (NEFT) will be out of operation.
HDFC-Linked Credit/Debit Card Payments Requiring OTP	OTP-based payments using HDFC Bank cards will be impacted.

Please take note that any transaction that requires real-time server authentication (that is, OTP-based payments or instant funds transfer) will be expected to fail during the maintenance timeframe.

HDFC Bank recommends that customers try to complete any outstanding transactions before the scheduled maintenance downtime.

Will Card Payments Work? A Detailed Breakdown

HDFC Bank maintenance will occur on May 9 and 10, 2025. Not every card transaction will be affected, but there will be specific payments that will be affected, which include some payments requiring an OTP-based verification. HDFC credit or debit card holders doing online or pre-scheduled payments should be on the lookout for potential issues.

Here is a simple summary of what you can expect:

Type of Card Use	Expected Availability	Remarks
Swipe/Tap at Point-of-Sale (POS)	Likely to Work	May go through if the transaction does not require OTP
Online Payments with Saved Card Details	May or May Not Work	Transactions could fail if OTP validation is delayed or fails
New Transactions Requiring OTP	Unavailable	Expected to be blocked during the maintenance window
EMI Payments / Auto-Debits	At Risk of Failure	Recommended to reschedule to avoid missed dues

Note: If you plan to make secure transactions using OTP, it's a good idea to have an alternative payment method or a card ready if required.

What You Must Do Before May 9

To prevent payment interruptions during HDFC Bank's planned maintenance on May 9 and 10, 2025, customers are requested to take proactive measures.

A little planning in advance can ensure that critical transactions are processed smoothly despite the temporary service disruptions.

Here are some suggestions:

If you are expecting to have rent, EMIs, or utility bills due during the maintenance, please transfer important funds ahead of time.
If you need access to recent payments, download last week's transaction receipts.
If you still wish to access your funds and are changing your UPI account to a new bank, please update your Google Pay, PhonePe, or other UPI app account settings.
Utilise debit and credit cards of other banks, or use mobile wallets such as Paytm, Amazon Pay, or PhonePe Wallet during the downtime.
Schedule important payments for May 8 or after 11:00 AM on May 10, when services are expected to resume.

Taking easy actions today could prevent delays and offer uninterrupted financial access throughout the maintenance.

Conclusion

The maintenance at HDFC Bank on May 9 and 10 will cause a temporary halt in working with long-term objectives to upgrade its digital infrastructure and user experience post-merger. For the population and businesses needing less bumpy banking, even a couple of hours' downtime has real-world implications. As is often the case with Kavita, even just a slight delay in receiving payments can escalate into financial trouble.

Customers are hereby advised to pre-plan their transactions to the utmost extent possible while opting for any other alternate modes of payment, along with communicating this information. Despite causing inconvenient moments, being able to strategise will aid in maintaining continuous operation amid the critical upgrade.
