Your M&T routing number depends on which state your account is in
M&T Bank does not have a single routing number for all accounts. Instead, the bank uses different routing numbers based on the state where your branch is located. This is common among large regional banks that operate across multiple states.
The routing number you need is the one that matches your branch location, not where you currently live or where you are sending money from. If you opened your account at an M&T branch in New York, you use the New York routing number even if you have moved to another state.
The fastest way to find your specific routing number is to look at the bottom left corner of any check you have from that account. The first nine digits printed there is your routing number. If you do not have a check, you can call M&T directly or log into your online banking account.
Key Takeaways
- M&T Bank routing numbers vary by state, so you need the number for the state where your branch is located.
- Your routing number appears on the bottom left of any check from your account as a nine-digit number.
- You can find your routing number by calling M&T customer service, logging into online banking, or visiting an M&T branch in person.
- Using the wrong state's routing number may delay transfers or cause them to fail, so confirm you have the correct one before sending money.
How to find your routing number online
Log into your M&T online banking account and go to the account details or account information section. Most banks display the routing number alongside your account number in this area. If you cannot find it there, look for a link labeled "bank information" or "wire transfer details."
You can also visit the M&T website directly and use their routing number lookup tool if you know your state. Enter your state and the tool will show you the routing number for that region. This works even if you do not have an account yet.
Calling M&T to confirm your routing number
Call M&T customer service at 1-800-724-2440. Have your account number ready when you call. A representative can tell you your routing number in under a minute and can also confirm whether you need it for a wire transfer, direct deposit, or another type of transaction.
Customer service is available during business hours, typically Monday through Friday. If you call outside those hours, you can leave a message or try the online lookup tool instead.
Why routing numbers matter for different types of transfers
A routing number tells the banking system which bank and which regional office should receive your money. When you set up direct deposit for a paycheck, your employer uses your routing number and account number to send funds to the right place. If the routing number is wrong, the deposit may go to a different bank or be rejected entirely.
Wire transfers also require the correct routing number. Unlike a check, which can sometimes be corrected if it goes to the wrong place, a wire transfer is usually final. Using the wrong routing number for a wire can mean the money goes somewhere you did not intend and is difficult to recover.
ACH transfers — the electronic transfers used for bill payments and money transfers between accounts — also use routing numbers. Getting this right prevents delays and failed transactions.
What to do if you cannot find your routing number
Visit an M&T branch in person with your ID and account information. Any teller can write down your routing number for you on the spot. This is also a good time to ask which routing number you need if you have accounts in multiple states.
If there is no M&T branch near you, calling customer service remains your best option. You do not need to be calling from the state where your account is located — M&T can look up your information by account number from anywhere.
Common mistakes when using a routing number
The most common error is using the wrong state's routing number. If you have moved or have accounts in multiple states, double-check that you are using the routing number for the branch where your specific account was opened, not the state you live in now.
Another mistake is confusing your routing number with your account number. Your account number is usually longer (10 to 12 digits) and appears after the routing number on your check. Both are needed for most transactions, but they serve different purposes.
Some people also mix up the routing number with the SWIFT code, which is used only for international wire transfers. If you are sending money outside the United States, ask M&T for the SWIFT code instead of the routing number.
Frequently Asked Questions
Is the routing number the same for all M&T branches in my state?
Yes. All M&T branches in the same state share the same routing number. You do not need to find a routing number specific to your individual branch location.
Do I need a routing number to use an ATM or debit card?
No. Routing numbers are only needed for transfers between banks, direct deposits, and wire transfers. You can use your debit card and ATM without ever knowing your routing number.
What if I have an old check with a different routing number?
M&T has changed routing numbers in the past due to mergers and reorganizations. If your old check shows a different number, call customer service to confirm which one is current for your account. Using an outdated routing number may cause transfers to fail.
Can I use any M&T routing number, or does it have to match my branch?
You must use the routing number for the state where your account is held. Using a different state's M&T routing number will not work and may delay or reject your transaction.
Where do I find the routing number if I bank online only?
Log into your online account and look for account details or bank information. If it is not there, call customer service or use the routing number lookup tool on the M&T website. You do not need to visit a physical branch.
