Information Based Indicia (IBI)

---

The Information Based Indicia (IBI), like other forms of postage such as stamps and meter impressions, is printed on an envelope in the upper right hand corner, or on a label for an envelope or package. It conveys evidence that postage has been paid and contains mail processing data requirements. In addition, the IBI contains security-related data elements.

The indicia is made up of human readable information as well as a two dimensional barcode with the following information:

		Licensing ZIP Code				Date of Mailing
		Destination Delivery Point				Postage
		Software ID				Digital Signature
		Ascending Register				Rate Category
		Descending Register				Reserve Field
		Algorithm ID				Indicia Version Number
		Device ID				Certificate Serial Number
