Maponics’ carrier route maps show “split routes” when they are defined by the USPS.

There are few companies that know more about postal carrier routes than Maponics.  In fact, the USPS is among our customers. Sometimes customers are confused by the same carrier route numbers appearing in more than one place on the map.

First you must remember that carrier routes (indicated by 9 digits - a 5-digit ZIP Code plus a 4-digit carrier route code) follow ZIP codes exactly.  So if you go from ZIP Code to ZIP Code, the same 4-digit carrier route code could be repeated.  That is not what is meant by a “split route”.

A split route occurs when that particular mail carrier delivers a pocket of addresses in one part of town, then travels to another part of the town and delivers to more addresses.  The area in between may be covered by another mail carrier.  So that first carrier’s route is “split”. On a map, this appears as two (or more) separate polygons, each with the same label.

Some marketing companies do their carrier route analysis only using the centroid (center point) of the carrier route. But without a map showing split routes, such as Maponics can provide, then your distance analysis may incorrectly include routes you really don’t want to target.
