USPS gives critical warning about mail-in ballots as Election Day looms next week

The U.S. Postal Service (USPS) is warning Americans looking to vote by mail to post their ballots today to ensure they are counted.

The USPS said it has already enacted "extraordinary measures" in preparation for Election Day on Nov. 5 in a press release posted Monday.

"If you choose to vote by mail, please mail early as every day counts," the USPS statement said.

"We continue to recommend that it is a good common-sense measure for voters who choose to mail in their ballots to do so before Election Day and at least a week before their election office needs to receive them. If a ballot is due on Election Day, the Postal Service recommends mailing the ballot by this Tuesday (October 29)."

A majority of U.S. states currently do not accept mail-in ballots that arrive after Election Day, according to the National Conference of State Legislatures.

However, 18 states and Washington, D.C., have varying grace periods to account for postal delays.
