USPS releases new details on Intelligent Mail Barcode implementation
February 29th, 2008 No CommentsIn a letter from Postmaster General John E. Potter, the USPS announced updates to the implementation schedule and other details regarding the new Intelligent Mail Barcode (IMB)
The IMB, also known as the 4-state barcode, is a replacement of the older Postnet barcode used to assist the post office in routing First Class, Standard Mail and Periodicals based letters, flats and some parcels. You probably have already received mail using the new IMB code. Where Postnet had short and tall bars that were level on the bottom, the IMB “sticks out” on both the top and bottom. The reason for this is to increase the amount of data that can be stored in the code. In the original implementation plan, mailers were to be required to switch over to the IMB by January 2009. While there are still many reasons for mailers to convert as soon as possible, the new plans are more flexible.
