By Meghna Sharma City Union Bank (CUB) is one of India’s long-established private-sector banks, with a strong branch network and a growing range of digital banking services. Although many routine transactions can now be completed through CUB Net Banking, Mobile Banking, WhatsApp Banking and self-service channels, customers still need to visit a branch for several important banking requirements.
A branch visit may be necessary for cash transactions, KYC updates, account documentation, cheque-related services, locker access, loan discussions, nomination changes and other activities requiring physical verification or assistance from bank officials. Knowing the bank’s working days and the correct official support channels can therefore save time and help customers avoid unnecessary visits.
City Union Bank’s current official website does not publish one universal opening and closing time for every branch in India. Its Customer Rights Policy recognises that working hours may change and requires such changes to be communicated in advance. Customers should therefore confirm the exact timing of their selected branch through CUB’s official branch locator or branch contact details rather than relying on one nationwide timing found elsewhere.
Here is a complete guide to City Union Bank branch timings, Saturday working days, holidays, customer-care numbers, card blocking, cyber-fraud reporting, grievance redressal, WhatsApp Banking and administrative-office contact details.

What Are the City Union Bank Branch Timings?
City Union Bank does not currently publish one identical customer-business schedule for every branch on its official website. The safest approach is to check the exact timing of the selected branch through the bank’s official Branch Locator.
CUB’s Customer Rights Policy states that changes in working hours should be communicated clearly and with advance notice. This supports a branch-specific approach rather than assuming that every CUB branch opens and closes at exactly the same time.
Customers planning cash transactions, account opening, KYC changes, locker work, loan documentation or other time-sensitive services should therefore confirm branch hours before travelling.
City Union Bank Working Days
City Union 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.
City Union Bank Saturday Working Schedule
The normal Saturday banking arrangement is:
- 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
A first, third or fifth Saturday can still be closed if another notified regional or public holiday falls on the same date.
City Union Bank Lunch Timings
City Union Bank does not publish one fixed nationwide lunch-break shutdown for every branch.
Customers should therefore not assume that all CUB branches completely close their counters during a particular lunch period. Staff and counter availability may be managed locally within the branch’s displayed working hours.
For transactions involving lengthy documentation or consultation with a particular officer, visiting during the earlier part of the branch’s working day can be more convenient.
City Union Bank Holidays
Apart from Sundays and the second and fourth Saturdays, City Union Bank branches remain closed on applicable bank and public holidays.
Regional holiday calendars differ between states because several holidays depend on local festivals and government notifications. Customers should check the holiday applicable to their location when planning important branch work.
Do All City Union Bank Branches Have the Same Timings?
Not necessarily.
City Union Bank’s official public material does not prescribe one universal branch timing for the entire network. Working-hour changes are treated as information that must be communicated to customers, which means the selected branch’s current schedule should take priority over generic timings found on third-party websites.
For exact opening and closing hours, customers should use CUB’s official Branch Locator or contact the branch directly.

City Union Bank Unauthorised Transaction and Cyber Fraud Reporting
Customers who notice a suspicious or unauthorised banking transaction should contact City Union Bank immediately.

Services Available When City Union Bank Branches Are Closed
Physical branch closure does not stop most routine CUB banking services.
Customers can continue using CUB Net Banking, Mobile Banking, WhatsApp Banking, ATMs, BNAs or cash-deposit machines, digital fund-transfer services and other supported self-service channels.
CUB’s 24×7 Customer Care at 1800 120 5000 also remains available for supported enquiries and service assistance.
Transactions involving original documents, physical signatures, locker access or direct verification may still require a branch visit.
Best Time to Visit a City Union Bank Branch
For routine banking work, customers should visit during the customer-business hours displayed or confirmed by their selected City Union Bank branch.
For account opening, KYC updates, loan documentation, locker-related work or transactions requiring detailed assistance, arriving well before the branch’s closing time is advisable.
Customers should also check whether the proposed date is a second or fourth Saturday, Sunday or applicable regional bank holiday before travelling.
For time-sensitive work, the official CUB Branch Locator and the branch’s own contact details remain the safest sources for exact operating hours.
