Tamilnad Mercantile Bank (TMB) is one of India’s long-established private-sector banks, with a branch network spread across several states and a growing range of digital banking services. Although routine transactions can now be handled through TMB M-Bank, Internet Banking, UPI and other digital channels, customers still need to visit a branch for many important banking requirements.
A branch visit may be required for cash transactions, KYC updates, account-opening formalities, cheque-related services, locker access, loan discussions, nomination changes and other activities that need physical verification or direct help from bank officials. Knowing the bank’s working days, branch schedule and official customer-care contacts can therefore save time and prevent unnecessary visits.
Tamilnad Mercantile Bank does not publish one identical opening and closing time for every branch on its current official website. The bank’s own customer-rights policy also recognises that branch working hours may change and must be communicated to customers. For an exact opening or closing time, customers should therefore check the selected branch through TMB’s official Branch Locator or contact the branch directly.
Here is a complete guide to Tamilnad Mercantile Bank branch timings, Saturday working days, lunch arrangements, customer-care numbers, card blocking, fraud and phishing reporting, grievance escalation, WhatsApp Banking, NRI support and Head Office contact details.

What Are the Tamilnad Mercantile Bank Branch Timings?
Tamilnad Mercantile Bank does not currently publish one single nationwide branch timing that applies to every location. Exact customer-business hours should therefore be checked branch-wise.
TMB’s current website provides an official Branch Locator for customers who need the address and contact details of a particular branch. The bank’s Customer Rights Policy also states that changes in working hours must be communicated to customers in advance.
For time-sensitive work such as cash transactions, KYC updating, account opening, loan documentation or locker-related services, customers should confirm the selected branch before travelling.
Tamilnad Mercantile Bank Working Days
Tamilnad Mercantile 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.
Tamilnad Mercantile Bank Saturday Working Schedule
The normal Saturday banking schedule is:
- 1st Saturday – Working day
• 2nd Saturday – Closed
• 3rd Saturday – Working day
• 4th Saturday – Closed
• 5th Saturday – Working day, if the month has one
A first, third or fifth Saturday can still be closed if another applicable state or regional bank holiday falls on the same date.
Tamilnad Mercantile Bank Lunch Timings
Tamilnad Mercantile Bank does not publish one fixed nationwide lunch shutdown for all branches.
Customers should therefore not assume that every branch closes completely during a standard lunch period. Staff and counter availability may be managed locally within the branch’s displayed working hours.
For transactions requiring detailed documentation or assistance from a particular officer, visiting during the earlier part of the working day can be more convenient.
Tamilnad Mercantile Bank Holidays
Apart from Sundays and the second and fourth Saturdays, TMB branches remain closed on applicable bank and public holidays.
Holiday calendars can differ between states because many holidays depend on local festivals and government notifications. TMB publishes state-wise bank holiday information on its official website.
Customers planning important banking work near a festival or long weekend should check the applicable holiday list before travelling.
Do All Tamilnad Mercantile Bank Branches Have the Same Timings?
Not necessarily.
TMB’s current official website does not prescribe one identical opening and closing time for its entire branch network. Exact business hours can therefore differ by location.
For the most reliable information, customers should use the bank’s official Branch Locator or contact the selected branch directly.

Phone: +91 461 2325136

Services Available When Tamilnad Mercantile Bank Branches Are Closed
Physical branch closure does not stop most routine TMB services.
Customers can continue using TMB M-Bank, Internet Banking, UPI, WhatsApp Banking, ATMs, eLobby services, balance enquiry, mini statements, card-blocking facilities and other supported digital banking services.
Services involving original documents, physical signatures, locker access or direct branch verification may still require a physical visit.
Best Time to Visit a Tamilnad Mercantile Bank Branch
For routine banking work, customers should visit during the customer-business hours displayed by their selected TMB branch.
Because TMB does not publish one identical branch timing for every location, checking the branch before an important visit is the safest approach.
For account opening, KYC updates, loan documentation, nomination changes, locker-related work or other transactions requiring detailed assistance, reaching 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 a regional bank holiday before travelling.
