The likely busiest post office day of the year is coming on Monday, Dec. 14.

An avalanche of some 2 million holiday cards and packages are expected to be mailed at Utah post offices on that day.

Since post offices will be packed on Monday, postal officials suggest Utahns use more convenient options, including mailing from home.

"The easiest way to alleviate holiday stress this year is to do all of your shipping online at, said USPS District Manager Ken McArthur.

"You can print postage and shipping labels directly from your computer with Click-N-Ship. We offer discounts when you ship online, and you get free Delivery Confirmation. Plus, you can schedule free package pickup online as well, so you can take care of all of your shipping from your computer without ever leaving home."

McArthur also touts Priority Mail Flat Rate boxes, which come in four sizes and are available free at any post office, online at or by telephone at 1-800-STAMP-24.

"Our eco-friendly Priority Mail Flat Rate boxes are the best bargain in shipping," McArthur said. "If it fits, it ships, up to 70 pounds, to any destination in the United States. Flat Rate boxes are always the same rate to any state."

Automated Postal Centers, located in 29 postal lobbies across the Wasatch Front, allow customers to purchase stamps and weigh and mail cards and packages 24/7, using their debit or credit cards. These APCs can be found in most Salt Lake metro area post offices; two Ogden post offices, Ben Lomond and Mount Ogden; and all post offices in American Fork, Layton, Roy, Orem, Provo, Logan and St. George.

The postal service expects to deliver 16.6 billion letters, packages and cards between Thanksgiving and Christmas, including 830 million pieces on the busiest mailing day, Dec. 14. The busiest delivery day will be Wednesday, Dec. 16.

Customers are encouraged to use Priority Mail through Dec. 21 and Express Mail through Dec. 23. For international destinations, Global Express Guaranteed service is available through Dec. 18 (later for some countries).
