Mail Delivery Only Five Days a Week?

Massive deficits could force the post office to cut out one day of mail delivery, the postmaster general told Congress on Wednesday, in asking lawmakers to lift the requirement that the agency deliver mail six days a week.

If the change happens, that doesn't necessarily mean an end to Saturday mail delivery. Previous post office studies have looked at the possibility of skipping some other day when mail flow is light, such as Tuesday.

Faced with dwindling mail volume and rising costs, the post office was $2.8 billion in the red last year, reports CNBC.

"If current trends continue, we could experience a net loss of $6 billion or more this fiscal year," Potter said in testimony for a Senate Homeland Security and Governmental Affairs subcommittee.

Total mail volume was 202 billion items last year, over 9 billion less than the year before, the largest single volume drop in history.

And, despite annual rate increases, Potter said 2009 could be the first year since 1946 that the actual amount of money collected by the post office declines.
