25 Highway Contract Route Addresses

251 Format

Print highway contract route addresses on a mailpiece as: HC N BOX NN. Do not use the words HIGHWAY CONTRACT, ROUTE, NUMBER, NO., STAR ROUTE, or the pound sign (#).

252 Leading Zero

A leading zero before the highway contract route number is not needed.

253 Hyphens

Print hyphens as part of the box number only when they are part of the address in the ZIP+4 file.

254 Star Route Designations

Change the designation STAR ROUTE, which usually refers to highway contract route, to HC.

255 Additional Designations

There should be no additional designations, such as town or street names, on the Delivery Address Line of highway contract route addresses. Street names used together with route and box numbers can create potential matching difficulty. Mailers are encouraged to use only one style of addressing. If secondary name information is used, however, place it above the Delivery Address Line.

256 ZIP+4

When applying a ZIP+4 Code to a highway contract route address, an exact match is preferred. If a box number is included in the address, the mailpiece must bear the appropriate ZIP+4 Code representing the range for that box number. When box number information is not available, the highway contract base record must be used.
