Where to exchange torn notes?

Excuse me, I was wondering if you could help me with a question. I've recently come across some torn notes and I'm not sure where I can exchange them for new ones. I've heard that some banks or financial institutions might offer this service, but I'm not entirely sure which ones. Could you please provide me with some guidance on where I can go to exchange my torn notes? I would greatly appreciate any information you can give me on this matter. Thank you very much in advance.
