For most purposes, mailing something to yourself for the postmark and keeping the envelope sealed would probably be adequate. It's possible to forge, but tricky enough.
- radlad 3y agoAs far as I know, this is pretty much the gold standard. Note that you need to send First Class to get a postmark in the US - not standard Priority Mail.
- grkvlt 3y agoyou realise it is possible to mail unsealed, open envelopes, right? doesn't seem that tricky...
- neilkk 3y agoYou seal the envelope with tape and put the stamp over the tape.
- eequah9L 3y agoYou send the envelope unsealed, then seal & stamp it later.
- yencabulator 3y agoThe word "stamp" is confusing here. You put postage on the letter, and the post office stamps the postage (to invalidate the postage). The stamp contains a date. You can't stamp something after having mailed it, that happens as part of the mail submission.
- eequah9L 3y agoOK, I suppose this could be arranged. The seal has to be over the whole of the "back side" of the envelope, where the flap is. Then put the address and the postage over that, and the post office stamps it. What confused me was how you would achieve post office stamping over a seal that's on the wrong side of the envelope, where the flap is.
