Mail mayhem on Monday marked the start of what was expected to be the season’s busiest mailing day of the year, according to the U.S. Postal Service.
The Postal Service expects more than 607 million pieces of mail to be processed Monday, compared to an average day of 528 million.
The Main Post Office in Chicago is marking the day by having Santa Claus greet customers bringing in their holiday packages, cards and letters.
The Postal Service expects six million people to visit Post Offices nationwide.
“We’re excited about the explosion in package growth,” said Chicago District Manager Karen Schenck, “and we want to make sure that we get every gift to its intended recipient in time for the holiday.”
The deadline for sending First-Class Mail in time for the holidays is Dec. 20, Priority Mail is Dec. 21, and Priority Mail Express is Dec. 23.
