After more than 20 years of service, the venerable POSTNet barcode on envelopes for automating and sorting mail retired on January 28. The Postal Service now requires that mailings have at least Basic-Service Intelligent Mail barcodes (IMb) to qualify for automation discounts. Mailers will need to switch to Full-Service IMb by January 2014 to receive maximum discounts at that time. Even though the Postal Service provided a lengthy lead time and a good deal of education on the discontinuance of the POSTNet barcode, the IMb requirement undoubtedly caught some smaller mailers by surprise. At the start of the New Year, less than half of commercial mail contained an IMb, suggesting a sizable number of mailers still needed to make the switch. While large commercial mailers were early adopters of IMb, many mid-sized and smaller mailers were hesitant to make the commitment and investment. Basic-Service IMb is not as big a step as the move to Full-Service IMb but it also yields fewer benefits. Full-Service Intelligent Mail will allow mailers to receive richer data about their mailings, but requires them to invest in hardware and software changes. The Postal Service wants to give mailers an incentive to make the conversion. It has proposed a one-time credit ranging from $2,000 to $5,000 to customers that make the conversion to Full-Service IMb. The credit would be based on the number of pieces the customer sends in a year. In an October Federal Register notice, the Postal Service laid out its proposal and further details are expected in a final rule. Is an incentive necessary to get mailers to invest in Full-Service IMb? If you are a mailer, do you plan to take advantage of the incentive?
