Undeliverable as addressed (UAA) mail is costly for the U.S. Postal Service and the mailing industry. Efforts to get a handle on the problem have been unsuccessful, as evidenced by the 2.1 percent increase in UAA mail from fiscal year (FY) 2011 to FY 2014. The Postal Service, mailers, and consumers all share responsibility for UAA mail.
