What happens if i dont put enough stamps on my letter?

Question

do they send it back or just not send it?

Answer 1

the recipient gets a note to pick up mail at the po for postage due

most time it gets sent since it's taking a while for all to get caught up with the increase

more than 4 pieces of regular (copy) paper is the next rate at .59

Answer 2

They'll send it back if you have a return address on it. If not, they'll either deliver it "postage due" so the person you're mailing it to has to pay, or they'll toss it in the dead letter office.

If you're mailing more than three or four pieces of paper in one standard letter envelope, you're safer putting two stamps on.

Answer 3

you'd get it back, provided there was a valid return address on the envelope.

just ask at the post office before you mail it, they can weigh it and you'll know exactly what postage is required.
