On the other hand, the USPS savings estimates are vulnerable to lower than anticipated volume and/or higher than expected costs. Some large mailers may develop techniques for totally bypassing the OCRs, for example, by applying bar codes to outgoing letters at the same time addresses are printed. This would be an extension of presorting letters to the carrier route level, which is apparently already competing with postal automation.

This downside potential is dramatized by comparing single-line OCR accept rates (percentage of mail fed to an OCR that is accepted by the machine) for different types of mail. USPS assumed, for example, an accept rate of 90 percent for presort first class mail but only 50 percent for collection box mail and 75 percent for bulk business mail.
