The customer service line at the post office in Susquehanna Township was long at times on Monday, as people began to mail their holiday presents and cards.
Officials said they moved 1.7 million pieces of mail from the facility on that day alone, up from the normal Monday average of 900,000.
The postal service recommends people get their holiday mail out as soon as possible. In order for a first class piece of mail to be delivered by Christmas, the deadline is December 20. The cut-off date for priority mail is December 21. The deadline for express mail is December 22.
Officials want to remind people to make sure they write down the correct address. Missing information could cause a delay in delivery. Holiday hours differ from location to location, so check with your local post office to find out when it will be open.
