IMb-Vestigate® from Bell and Howell is a software application that compares USPS unclaimed postage reports against data from the NetSort Sorting Platform or manually imported Mail.dat files and provides the data you need to validate or dispute USPS results. IMb-Vestigate® quickly scans up to one year of mail production data to identify discrepancies in the USPS scorecard results. The IMb-Vestigate® system uses the same computer hardware as the NetSort Server system. This allows the IMb-Vestigate PC to be used as a repository for NetSort Data backup files or temporarily act as a NetSort server if needed.


Bell and Howell’s IMb-Vestigate® uses the database of all read or printed IMBs, collected from mailpieces passing through the NetSort sorting systems, or captured in a mail.dat file. This data is compared to the IMb codes of the undocumented pieces from the USPS. The findings are quickly detailed and presented in a series of displayed data, text files, and reports. The data import method for these large batch style searches matches the format used by the USPS, making file format conversion unnecessary. When only a few samples are needed, you may perform simple queries for individual IMBs.

Integration and installation is supplied by the Bell and Howell Service organization upon initial purchase agreement. We have unsurpassed project planning and system set up. After your software is installed, Bell and Howell offers ongoing technical support and IMb-Vestigate® Software updates which are supplied through Software Maintenance Agreement.
