How many stamps for a manila envelope?

Question

The envelopes are 9" x 12" and will only have two regular pieces of paper enclosed. I don't know if they will need one of two stamps!

Thanks!

Answer 1

It depends on weight.

Answer 2

because of the size you will need to weight it  I would guess also it would need more than one stamp because of being oversize.Most of ones we mail at the office takes .78 cents in stamps

Answer 3

Two.  Postage is higher for large envelopes.  We use a stamp program at work and they always require two stamps.
