Tuesday is the last day the Post Office can guarantee delivery by Christmas of First-Class Mail.
If you're sending packages by postal service, then Wednesday, Dec. 20 is the deadline to ship it as priority mail. 200 million packages are delivered each week starting from December 11 through Christmas Eve. The organization expects to process and deliver almost 3 billion pieces of First-Class Mail, including greeting cards this week alone.
"It's obvious, people are shipping and mailing more items out of state and to different areas of the state than ever before", Smith added.
"It handles all the mail for 950,951, and 931 which goes all the way down to King City", said Ruiz, as he walked down a long corridor to the interior of the distribution center. "With Informed Delivery, you can track your packages and check your mail from anywhere".
Christmas opening hours details are available in each delivery office.
"I know from a national perspective that (online shopping) has picked up, which means shipping has picked up", she said.
With Christmas on a Monday, most retailers have one less day to get packages delivered on time.
"The Postal Service is well-prepared to meet our customers' needs during the holiday season, especially as demand for package deliveries continues to grow", said Megan J. Brennan, postmaster general and CEO.
It says that final deliveries nationwide are Saturday, with services resuming on 28 December.
If you have some last-minute presents that you need to ship, your time to do so is running out.
One in five (21%) said at least one delivery did not arrive at all and 18% reported at least one of their packages arrived late.
So, no matter which carrier you select to deliver your Christmas cards and packages this week, the best advice is to send it as soon as possible.
