#ZIP Code Database
Accumail (Do not get Zip++ as the company is no longer in business) is
exactly what you want. It can either give you the information on an
individual basis, or in batch with a DBase or ASCII fixed list. It is
updated quarterly and comes on a CD-ROM. It will also help you earn postal
discounts and already handles the Delivery Point Code for the 11 digit
Postnet barcode (Required come March for Postnet discounts) Should you
have any more questions on the product or wish to order, give me a call.
Regards,
Hal
