You can buy postage through GNPS's unique "postal hash" system.

Instead of buying traditional, complicated postage stamps, you recieve a page to print out which contains your stamp (called a "postal hash" or "digital postal stamp") to glue on your envelope. Drop it off at a GNPS location to complete your service. How easy is that?

Request a postal hash using the button below. We highly recommend that you do NOT view this website on a mobile device.
