The Validate Address service in Spectrum Technology Platform's Universal Addressing Module matches input addresses to addresses in the USPS database in order to correct postal information. It also adds additional postal information that can potentially earn you postal discounts (such as ZIP + 4 Codes).
During address matching and standardization, address lines are separated into components and compared to the contents of the USPS database. Any address information not used as part of matching is referred to as dropped address information. If a match is found, the input address is standardized according to the contents of the database. If your data contains addresses for which no database match is determined, you can elect to normalize input addresses. The normalization process attempts to format the address lines according to conventions outlined in USPS Publication 28. When the normalization option is invoked and no database match is found for a particular address, Validate Address attempts to recognize the individual elements and formats them according to USPS conventions.
