"The U.S. Postal Service doesn't run on your tax dollars. It's funded solely by stamps and postage." -- American Postal Workers Union, AFL-CIO in a July 8, 2013, television ad

There’s been a lot of conversation lately about proposed cuts to the U.S. Postal Service, particularly the idea of ending Saturday delivery.

PolitiFact Georgia reader Wallace Cooper said he was skeptical about a specific claim in a recent television ad about the taxpayer cost of delivering the mail and asked us to do some fact-checking.

“Members of the American Postal Workers Union handle more than 165 billion letters and packages a year. That’s about 34 million pounds every day. Ever wonder what this costs you as a taxpayer? Millions? Tens of millions? Hundreds of millions?” a voice says in the 30-second ad.

The answer: “Not a single cent.”

Deliveries are solely funded by stamps and postage, the voice says.

The ad was put together by the American Postal Workers Union. The union writes on its website that the ad was created to combat “detrimental legislation.”

The Postal Service boasts that nothing will keep its mail carriers from their appointed rounds. We at PolitiFact Georgia share a similar intrepid ethic regarding getting to the bottom of a claim. So what did we find?

The Postal Service says on the facts page of its website that it does not receive tax dollars for its operations, but some context is necessary here.

First, let’s look at its current situation.

Before 1971, the Postal Service received annual appropriations from the federal government. Since then, it has operated independently, with revenues generated through the sales of postage stamps and services.

But Congress does give the Postal Service $100 million a year to compensate the agency for revenue loss by providing, at congressional direction, free mailing privileges to blind people and overseas voters, a congressional report noted. The $100 million is less than 1 percent of the Postal Service’s annual budget.

In 2012, the Postal Service pulled in about $65 billion in revenue, it says on its website. That’s $10 billion less than what collected in 2008, the year the Great Recession took hold. By some reports, the Postal Service is losing $25 million a day. The volume of mail the Postal Service handles has declined by nearly 27 percent since 2008, as Americans rely more on email communications instead of letters.

The Postal Service’s debt rose from nothing to $10.2 billion between federal fiscal years 2005 and 2009, according to a congressional report. The federal fiscal year begins Oct. 1 and concludes Sept. 30.

Another congressional report found Postal Service operating costs may be the largest reason for its financial troubles. In 2006, Congress passed legislation requiring the Postal Service to pre-fund its future retirees’ health benefits at a cost of approximately $5.6 billion per year.

The Postal Service has cut expenses through a hiring freeze, offering early retirement to longtime employees and closing some district offices. It’s also increased revenue in recent years through several increases in the price of a postage stamp.

In 2009, the Postal Service began borrowing money from the U.S. Treasury Department to deal with its troubles. Some news accounts report the service reached its borrowing limit of $15 billion in September 2012.

Sally Davidow, a spokeswoman for the union, said the Postal Service had to borrow the money to offset the health benefit changes. She argued that health benefits are not part of the Postal Service’s operating expenses.

“(The Postal Service) is required to pay that money back,” Davidow added. “Borrowing money is different than relying on taxpayers.”

Davidow argued in the union’s defense that the Postal Service has $46 billion in its retiree health benefits fund, but the federal government won’t let the agency borrow from it.

The Postal Service wrote in a November 2012 press release that it had a record fiscal year deficit of nearly $16 billion. The agency attributed about 70 percent of that net loss to the health care requirement.

To sum up, the American Postal Workers Union claimed in its television ad that the U.S. Postal Service doesn’t operate on taxpayer dollars and and it’s solely funded by stamps and postage. The Postal Service has borrowed money from the government in recent years, primarily it says, to cover the cost to pre-fund employee health benefits.

The first part of the statement is on target. The second part, however, gets a return to sender.

We rate this claim Half True.
