The USPS Tracking Bulk Query Utility is a Query application which allows the user to query the USPS API using the USPS Tracking Number. Usually Tracking Numbers are given out to packages mailed through USPS which have a Delivery Confirmation. The DigiOz USPS Tracking Bulk Query Utility Application allows the user to run multiple Tracking requests at the same time (could track thousands of packages with one query).
