Can I process batches of ZIP+4 look-upssuch as an entire databaseonline?
The purpose of the ZIP+4 look-up system on our WWW server is to avail the public of a simple means of obtaining ZIP+4 code information. The primary audience we seek to serve are customers who occasionally require ZIP+4 codes. ZIP+4 Look-Up is intended for interactive use, not automated script processing. Although we do not intend to impose a limit on the number of address inquiries we allow a customer to request in a given session, if we determine that our open-access policy is being abused or overburdened, we will have to review it. Regardless, we do not intend to offer batch processing capabilities via this service.
