You’re standing in the parking lot or staring at your phone, and you need to know one thing: is M&T Bank open today? If today is Sunday, January 18, 2026, the short answer is no. Most physical M&T Bank branches are closed on Sundays. Honestly, it’s a bit of a bummer when you have a check that needs a human teller, but that’s the standard retail banking rhythm in the U.S.
But wait.
Tomorrow is Monday, January 19, 2026. That is Martin Luther King Jr. Day. Since it is a federal holiday, M&T Bank branches will be closed then, too. If you were planning to "just go tomorrow," you’re going to find a locked door and a quiet lobby.
The Reality of Branch Hours
Most M&T locations operate on a pretty tight schedule. Monday through Friday, you can usually catch them between 9:00 AM and 5:00 PM. Some stay open until 6:00 PM on Fridays because, well, people get paid and things get hectic. Saturdays are a coin toss. Many locations open for a few hours—usually 9:00 AM to 12:00 PM—but plenty of smaller branches stay dark all weekend.
Sundays? Almost universally closed.
If you’re lucky enough to be near a branch in a high-traffic retail area or a major city hub like Baltimore or Buffalo, you might find an exception. But 99% of the time, the physical doors are locked tight today.
Why "Closed" Doesn't Mean "Off-Limits"
Just because the lights are off doesn't mean you can't get stuff done. Banking isn't what it was in 1995. You've got options that don't involve waiting for a teller named Linda to finish her coffee.

- The M&T Mobile App: It’s actually pretty solid. You can snap a photo of a check and deposit it in about 30 seconds. Just remember, since today is Sunday and tomorrow is a federal holiday, that money won't "officially" start processing until Tuesday.
- ATM Access: M&T has a massive network. You can pull cash, check balances, and even deposit cash or checks at most of their machines 24/7.
- Customer Service Lines: Surprisingly, M&T keeps the phones manned more than the desks. Their general customer service (1-800-724-2440) is technically available 24/7 for automated stuff, but if you need to talk to a human about online banking or a credit card, they usually have staff available from 9:00 AM to 5:00 PM ET even on weekends.
The 2026 Holiday Trap
People always forget the "observed" rule. In 2026, the calendar is a bit tricky. When a holiday falls on a Sunday, banks usually observe it on Monday. Since MLK Day is always a Monday, there’s no confusion there—it’s a two-day lockout for anyone needing in-person service this weekend.
Here is the thing: M&T Bank follows the Federal Reserve holiday schedule. If the Fed is closed, M&T is closed.
Digital Workarounds for Today
If you absolutely have to move money right now, use Zelle. It's built into the M&T app. It doesn't care that it's Sunday. It doesn't care about Martin Luther King Jr. Day. It just moves the numbers.
If you are trying to open an account, you can actually do that entirely online today. You don't need a branch manager to sit across from you. Just have your ID ready and a few minutes to kill.
What to Do Next
Since you can't walk into a branch today or tomorrow, here is your game plan:
- Check the App First: If it’s a deposit or a simple transfer, don't wait for Tuesday. Do it now so you're first in line when the "business day" actually starts.
- Locate an Advanced ATM: Use the M&T site locator to find an "Easy Deposit" ATM. These handle stacks of cash without those annoying envelopes.
- Plan for Tuesday: If you have a complex issue—like a notary service, a medallion signature, or a safety deposit box—set your alarm for Tuesday morning. Expect the branches to be busy since they've been closed for two days straight.
- Verify via Telephone: If you're unsure about a specific local branch's Saturday/Sunday status in the future, call their direct line. Some grocery-store-based branches have weird hours that don't match the standalone buildings.
