Stamps created by Endica exist in three different products:

PictureItPostage stamps are the basic stamp offered by Endicia. They are identified by the words "" in the colored frame surrounding the denomination and control number.

myartstamps are are identified by the addition of "" to the basic PictureItPostage stamp at the bottom of the design area.


Xpress It Postage

of a superscript number preceding the the stamp vendor letters.
