The Kamp Database is a collection of ASCII files compiled by KampData designed to be imported and used by DynamicZip.

Since 1995 we have relied on the ZIPsales Database to provide the required data. As of build 74 we have added the option to use the Zip2Tax Database. However both of these databases are built on the framework of ZIP's and city names provided by the USPS. The USPS data is rather messy and includes multiple spellings for the same place. In an effort to clean up and standardize this data, we introduced naming rules. However, the real solution is to use the USPS preferred city names wherever possible. To accommodate this, we now purchase redistributable USPS data and groom the data with software and by hand. The result is good clean data that includes alternate spellings which DynamicZip resolves back to the USPS Preferred City Names.
