UCO Bank is a major public-sector bank with a nationwide network of branches, ATMs and digital banking channels. While customers can now complete many everyday transactions through UCO mBanking Plus, Internet Banking, UPI and WhatsApp Banking, branch visits remain necessary for several banking requirements.
Customers may need to visit a UCO Bank branch for cash transactions, KYC updates, account documentation, cheque-related services, locker work, loan discussions, nomination changes and other activities requiring physical verification or direct assistance from bank officials. Knowing the bank’s working days and the exact business hours of the selected branch can therefore prevent an unnecessary trip.
UCO Bank does not prescribe one identical opening and closing time for every branch across India. Its banking-hour policy allows timings to differ between states, districts and even branches in residential, commercial, mandi or other special locations. The bank’s Citizen’s Charter also requires branches to display their business hours. Customers should therefore treat the timing displayed by their specific branch as the final schedule.

Here is a complete guide to UCO Bank branch timings, Saturday working days, holidays, lunch arrangements, customer-care numbers, debit-card blocking, grievance contacts, NRI support, WhatsApp Banking and other official support channels.

UCO Bank uses locally notified and displayed branch business hours rather than one nationwide fixed timing. Customers handling time-sensitive work should confirm the selected branch through UCO Bank’s official Branch/ATM Locator or directly with the branch.
What Are the UCO Bank Branch Timings?
UCO Bank’s official policy does not set one identical business-hour schedule for every branch in India. Banking hours are implemented according to state-level arrangements and local notification, and different districts within the same state may have different timings.
Branches located in residential and commercial areas of the same district may also follow different schedules. Mandi branches and other special-area branches can have timings designed around local public convenience. This is why a general timing quoted online should not automatically be treated as the official schedule of every UCO Bank branch.
UCO Bank’s Citizen’s Charter requires branches to display business hours and to attend customers who are already present in the banking hall at the close of business hours. Customers planning important work should check the branch’s displayed schedule or use the official Branch/ATM Locator before travelling.
UCO Bank Working Days
UCO Bank branches normally operate from Monday to Friday, except when a date falls on an applicable bank or public holiday. Saturday operations depend on which Saturday of the month it is.
UCO Bank Saturday Working Schedule
- 1st Saturday – Working day
- 2nd Saturday – Bank holiday
- 3rd Saturday – Working day
- 4th Saturday – Bank holiday
- 5th Saturday – Working day, if the month has one
The nationwide banking arrangement makes the second and fourth Saturdays public holidays for scheduled and non-scheduled banks. Saturdays other than the second and fourth are normally full working days unless they coincide with another separately notified regional or public holiday.
UCO Bank Lunch Timings
UCO Bank does not publish one nationwide lunch shutdown applicable to every branch. Its service-at-the-counter guidance requires staff availability throughout prescribed business hours and states that no counter should remain unattended during banking hours.
The bank’s policy also says work should be allocated so that teller counters are not closed during banking hours and uninterrupted service is provided to customers. Therefore, customers should not assume that a UCO Bank branch officially closes all counters at one fixed lunch time.
For transactions requiring lengthy documentation or consultation with a particular officer, visiting earlier during the displayed branch hours may still be more convenient.
UCO Bank Holidays
Apart from Sundays and the second and fourth Saturdays, UCO Bank branches remain closed on applicable bank and public holidays. Regional holiday calendars differ between states because many holidays depend on local festivals and government notifications.
A holiday observed by branches in one state may therefore not apply to UCO Bank branches elsewhere. Customers should check the applicable regional bank-holiday calendar before planning important branch work.
Do All UCO Bank Branches Have the Same Timings?
No. UCO Bank explicitly allows banking hours to vary according to location. Different districts can have different timings, branches in residential and commercial locations within the same district can follow different schedules, and special-area branches can operate under locally notified timings.
For this reason, the most reliable source is the timing displayed by the particular branch. UCO Bank also provides an official Branch/ATM Locator where customers can identify the selected branch and obtain its contact details.
UCO Bank Customer Care Numbers
UCO Bank currently lists 1800 8910 as its principal toll-free customer-care number. The number is used for UCO SAMPARK and is available on a 24×7 basis for customer assistance and grievance registration.
Customers should note that older UCO Bank documents may still show 1800 103 0123. The bank’s current 2026 website displays 1800 8910, so the newer number should be preferred.

UCO Bank ATM and Debit Card Blocking
If a UCO Bank Debit Card is lost, stolen or suspected of being compromised, customers should block it immediately instead of waiting for the branch to open.

Debit Card hotlisting is also available through SMS from the registered mobile number. Customers can send HOT to 9230192301 to hotlist cards linked to that mobile number. The bank also supports card-specific or account-linked hotlisting formats using the last four digits of the card or the 14-digit account number.
UCO Bank Unauthorised Transaction and Cyber Fraud Reporting
Customers who notice suspicious or unauthorised digital banking activity should contact UCO Bank immediately through its current customer-care number:

The bank advises customers who have mistakenly disclosed account, ATM or OTP information to call customer care promptly so affected digital channels can be blocked. Customers can also use UCO Secure or the Digi-Safe facility in UCO mBanking Plus to disable supported digital banking channels.
For cyber financial fraud, customers should additionally contact the National Cyber Crime Helpline at 1930 and report the incident through the official national cybercrime reporting system.

Services Available When UCO Bank Branches Are Closed
Physical branch closure does not stop most routine UCO Bank services. Depending on the service and account, customers can continue using:
- UCO mBanking Plus
- Internet Banking
- UPI
- WhatsApp Banking
- ATMs and supported self-service facilities
- Balance enquiries and mini statements
- Fund transfers and bill payments
- Debit Card controls and hotlisting
- UCO Secure / Digi-Safe digital-channel controls
- 24×7 UCO SAMPARK customer support
Services involving original documents, physical signatures, locker access, certain KYC procedures or direct physical verification may still require a branch visit.
Best Time to Visit a UCO Bank Branch
For routine banking work, customers should visit during the business hours displayed by their particular UCO Bank branch. Because the bank allows location-specific operating schedules, the exact branch timing should be checked instead of relying on a single nationwide opening and closing time.
For account opening, KYC updates, loan documentation, nomination changes, locker-related work or transactions requiring consultation with an officer, reaching well before the displayed closing time is advisable.
Customers should also check whether their proposed visit falls on a Saturday, near a regional festival, on a national or bank holiday, or during a long holiday weekend. UCO Bank’s official Branch/ATM Locator and the branch’s displayed business hours remain the most reliable sources for an important visit.
