Do I ever need to add postage to a postage paid envelope?

you shouldn’t need to….

Only if you are sending something that weighs more, or if you want to upgrade to, say, next day air or something like that.

Yes. I found this out the hard way. My papers never arrived, nor were they returned to me. So, I have no clue what happened to the envelope containing my social security numbers for all my family members, birth certificates, driver licenses, bank statements…it’s all out there somewhere :(

To be safe, yes, i would add postage.

You don’t need to add any postage to a paid envelope as the name suggests, it is paid, which means that the company and the post office have a private agreement between them. If you are still unsure, just take one of the empty envelopes and take it to a post office to confirm.

Maybe you can PM Astrochuck to be sure.

No, unless you have the blank prepaid envelopes that have the postage amount listed on them. I’m not even if sure we (USPS) even carry those anymore. The prepaid addressed envelopes you’re given by businesses are paid at the other end so you needed worry. Everything is charged to their account. Weight isn’t a concern either.

The blank envelopes with the postage printed on them are called stamped envelopes, and they are still sold ( 54c each ). The envelopes distributed by various businesses that state “postage will be paid by addressee” with the large black bars on the right side are called BRM ( Business Reply Mail ). Businesses that receive these envelopes generally set up accounts with money that will pay for the envelopes as they come in. Heavy letters are just charges 17c for each additional oz. over the first oz.

If you want to ensure that they arrive to their intended destination, then yes you should add extra postage.You should take your envelope to the post office to be sure. You should also send it certified mail to ensure proof of delivery.
