Accurate addresses are necessary to get your mail delivered.  Inaccurate addresses waste your time and money. Accurate addresses are required in order to mail at Standard Mail or Presorted First-Class rates, which give you substantial postage discounts. To help you maintain address accuracy, UWF Postal Services offers to all authorized customers certified address matching software service (described in CASS Certification section below), which will improve your addresses as well as certify them for Standard Mail (bulk) mailings. This software is for U.S. addresses only and checks every address against the U. S. Postal Service National Address Database. The software validates addresses and Zip Codes (CASS and DPV), as well as matching names to addresses (NCOA Link). It will also automatically arrange your addresses for presorting when printing labels saving you time, check for duplicates and, if you desire, it will provide for preprinting the required Intelligent Mail barcode for automation mailings and even bigger postage discounts.

Address "Move Update" Requirement

As indicated in Chapter VI of this guide, U. S. Postal Service “Move Update” regulations require that addresses used by UWF offices, organizations and departments must be updated within 95 days  prior to a mailing in order to use and qualify for Standard and Presorted First-Class Mail (bulk mail) discounted rates. There is no exception to this requirement. In fact, the Postage Statement submitted with the discounted mailings must be signed certifying, under penalty of law, that the addresses have been updated as required. UWF Postal Services offers this service free of charge for mailings we process.  Off-campus vendors and mail service providers will provide this service as well at a cost to the mailer. UWF mailers who prefer to prepare their own mailing are required to submit to UWF Postal Services with each bulk mailing a form verifying that the address list used for the discounted-rate mailing has been updated as required using an USPS approved method (such as endorsements). Address List Certification Form (PDF). When departments receive new or updated addresses from the USPS the address database must be updated as well with the changes. Departments must set up a process for making changes to the database, to continue to qualify for discounts. Call UWF Postal Services for more information at 474-3211 or 474-2437.

CASS Certification

The use of Coding Accuracy Support System (CASS) and Delivery Point Validation (DPV) certified software is an approved method of updating ZIP codes. While using a manual method of updating ZIP codes is authorized within the last 95 days of a bulk mailing, as described previously in Chapter VI, Section F, mailers may find it less time consuming and more accurate to use CASS/DPV to verify address lists. UWF Postal Services has U.S Postal Services approved CASS/DPV and NCOA Link certification software that will update ZIP codes and verify and update addresses and check name and address validity. This software is updated every 3 months to insure addresses are current and accurate. UWF mailers may submit their address lists to the Manager, UWF Postal Services as an email MS Excel attachment in order to have the addresses and ZIP Codes updated and “cleansed”. Cleansed means that the street addresses will be matched to the ZIP codes and checked for validity, that the street names, directional indicators, suffixes, spelling, punctuation, abbreviations, format, etc. will be checked for accuracy and updated, names and addresses will be matched and validated, and that duplicate addresses will be identified. Addresses will be automatically corrected if necessary. Within 3-5 days the UWF office, organization or department submitting the addresses will be notified of CASS or NCOA Link certification, and if requested, a list of addresses that there were problems with and that could not be corrected will be provided. These “bad addresses” should be manually researched and updated by the mailer and cannot be used for bulk mailings until corrected with a valid address. A copy of the certifications will be kept on file for each mailing.
