Publishers need to be in compliance with rule changes and to ensure their ability to save money. A new requirement for that rate in 2001 is that some form of sequencing be used, and updated every 90 days. Submit your list on cards to delivery post offices under Domestic Mail Manual A920.2.9, which provides for free walk-sequencing.
Some offices prefer to work from a list.
Many papers sequence larger routes for high-density rate, but not all routes, or at some small offices. The National Newspaper Association has obtained a form from USPS Business Mail Preparation allowing post offices to approve sequencing if still correct, and no changes in route sequencing since last sequenced. That form, and the letter authorizing its use, should be submitted every 90 days to each office. Watch Pub Aux for details of this program when final. I recommend walk sequencing, which is in precise delivery order.
