Address Hygiene

Address Hygiene services are also known as address standardization, address correction, CASS certification and database hygiene. It increases the deliverability of mail and is necessary for many postal discounts.

Address Hygiene formats mailing addresses in strict accordance to USPS standards and appends ZIP Plus4 codes, carrier routes and Delivery Point Barcodes (DPBC). The service includes a CASS certification report proving the mailing list was updated to USPS standards.

Address Hygiene now includes Locatable Address Conversion System (LACS, recently renamed LACS^Link) service which corrects addresses in areas that have undergone permanent address conversions. The LACS database consists of address corrections primarily as a result of Emergency 911 system implementation. These typically involve renumbering and renaming rural route, highway route and box number addresses as city-style addresses.

Address Hygiene now includes Delivery Point Validation (DPV) which checks the integrity of mailing addresses by determining if they are valid delivery points down to the unit number. Matching is against the USPS master database of all delivery points in the United States. DPV tells you which of your addresses are valid and which are not.

Address Hygiene is offered by Peacock Data as Address Standardization.
