Heavy Letter Mail Warning
Return to News Items June 28, 2007Heavy letter mail - it's just what it sounds like. Letter-sized mail that is heavy. When the new rate increases and postal rate restructuring took effect, so did a new ruling on heavy letter mail.
Rule 1: Heavy letter mail weighing more than three ounces must have a barcode in the address block. (Note to our clients: don't worry - the mail piece will have a barcode)
Rule 2: Heavy letter mail weighing more than three ounces must be in a sealed envelope.
Rule 3: Heavy letter mail cannot contain stiff enclosures nor be prepared as a self-mailer or booklet-type mailpiece.
And if your letter weighs more than 3.5 ounces, it will mail as a flat.
