Carrier Routes

Carrier Routes

Carrier Routes are the areas where individual US Postal Service carriers deliver mail.  They are much smaller than ZIP Codes, with roughly fifteen Carrier Routes per postal ZIP Code.

They are useful in helping to reduce direct mail marketing costs while increasing response rates.  The use of Carrier Routes helps to keep your market in focus to efficiently define target market areas to send mail and to maximize discounts from the US Postal Service.

Carrier Routes can also be used as building blocks to create territories for tasks such as canvasing and other door-to-door visits.  See the “What Are Carrier Routes” Explainer below.


SpatialPoint offers a range of solutions for using Carrier Routes 

Raw Data for Desktop Applications

Offering the raw boundary data to be used in desktop mapping software such as MapInfo Professional, Esri ArcGIS, etc., for analysis, mailings, overlaying demographics, etc. (We call these Knowledge Worker Applications.)

Complete Turnkey Applications For Your Website

Offering EDDM (Every Day Direct Mail)-type applications where users click on the Carrier Route shapes while the application tallies basic statistics.  Additional demographics (income, age groups, etc.) can be added, too. We can host the application and have it seamlessly fit within your website. Or, you can host it. 

Not quite or beyond EDDM

While EDDM is popular, SpatialPoint can supply more sophisticated versions that include more demographics, ZIP+4 data, and your own data. Or, simpler versions that only include ZIP Code boundaries or US Census Tracts (for example) can be supplied.  Other variations are to have multiple versions of the tool on your site tuned to the different vertical markets that you serve or to include multiple locations/areas to analyze.

Most anything is possible. Contact us to go over your ideas and needs.

What Are Carrier Routes?

A postal carrier route is the group of addresses to which the USPS assigns the same code to aid in efficient mail delivery. These codes are 9-digits: the first five represent the ZIP Code, one letter for the carrier route type (R for Rural), and 3 numbers for the carrier route code. For example “60018C017” or “46383R018.” Typically, each carrier route is related to where a particular mail carrier delivers.

There are roughly 600,000 carrier routes in the United States. Approximately half of these represent actual physical geographic boundaries where mail is delivered. The other half are dedicated to Post Office Boxes. With approximately 40,000 ZIP Codes in the US, this averages out to 15 carrier routes per ZIP Code. Some ZIP codes are broken down into fewer or more Carrier Routes and it ranges from one to over 100 Carrier Routes per ZIP Code.

The makeup of a carrier route can be businesses, multiple family dwelling units (apartments or condos), or single family dwelling units.
