National Zone Chart Matrix changes

• USPS has added 5-Digit origin exceptions for certain Military locations into the National Zone Chart Matrix.
• To better classify existing zone exceptions applicable to specific groups of mail the USPS^® will be adding new code values “00” and “99” to the “mail type” field in the National Zone Chart Matrix “exceptions” file. This change will assist mailers in identifying when a zone exception is applicable.
