People's United - Personal Banking
How can I activate my new M&T Visa® Debit Card?
To activate your card, simply call the number shown on the sticker on the front of your card or use it at any M&T ATM, including former People’s United ATMs. Once the card is activated, remove the sticker and sign the signature panel on the back of the card. Then, destroy your old People’s United Bank Debit Card.
