The final benefit of address standardization is deliverability of a mailpiece. Complete addresses that have matched Postal Service files or directories have a better chance of being promptly and correctly delivered. Printing complete information on a mailpiece and eliminating extraneous information that can confuse delivery personnel or be misread by postal equipment does a lot to get the mail delivered on time. We are continuing to explore ways to improve the processing and delivery of mail in a timely, cost–effective manner. Address standardization is a positive step toward improved address quality and is a cost–effective operation for both postal customers and the Postal Service.
