All mail must have a department name and/or department number in the return address. The Mail Room is unable to charge the correct departments on business reply mail and postage due mail and it also prohibits its ability to return this mail. Do not use letters with the address on the back of the mail. The post office only scans the front of the letter and then forwards the item to the recipient. They return a scanned copy of the front of the letter with an address correction attached that allows us to update our files. The address being on the back again leaves the mail room without the ability to track where this mail needs to be returned and charged to.
All mail that has flaps on the side of the envelope instead across the top is required to be sealed prior to delivery to the mail room. The mail machine is unable to seal mail that has flaps on the side.
All mail must be rectangular, flexible and uniform in thickness. If not mail is charged as a package.
If items exceed these limits they are charged at the next highest rate. Examples:
Minimum mail size: 5” long x 3 ½” high x 0.007” thick
