$0.85 Cent Stamps for Wedding Invitations

After January 27th, 2019, you'll need a $0.85 stamp to mail any of the following first-class letters:

  • 1st class, 3 oz
  • 1st class, 2 oz - odd size
  • If your letter weighs 2 oz but is also odd-sized/non-machinable you'll need a $0.85 stamp.

You can use our postage calculator to determine which face-value your mailing will need, but be sure to double-check the weight of your invitations with your local USPS post office before ordering postage online.
