Official Addressing Standards

To facilitate addressing in Clay County, formal standards (PDF) were adopted in 1998.

Clay County Addressing System

The Clay County E-911 “locatable address system” follows the National Emergency Numbering Association standards used by counties statewide.

North-south routes in the county are known as “Streets” (ST).  East-west routes are known as “Avenues” (AVE).  All US and state highways retain their names designation (HWY).  The county is divided into two main areas, North (N) and South (S), divided by HWY 10.

The one-to-five digit specific location address (called an Address Number) specifies the distance, in miles and tenths of miles, from Highway 10 or the Red River in Moorhead.  Thus, 15203 210 ST N is 15.2 miles north of HWY 10, and 210 ST N is 21 miles east of the Red River.  The specific location address also indicates the precise distance from a section corner to within 10.6 feet.  There are 1000 addresses per mile.  

The streets and avenues in the county are marked with green intersection signs.  Blue address number signs are also provided by Clay County.  Please report missing or damaged signs to gis@claycountymn.gov or 218-299-5003.

Addressing Guidelines

All addresses must be fully spelled out, and abbreviated by using the Postal Service™ Standard Abbreviations. Format all lines of the address with a uniform left margin. Addresses should consist of a recipient line, delivery address line and last line.

• Recipient Line: Name of a person or business.
• Delivery Address Line: House number listed 1st followed by the street name, street type, post directional and secondary address (if needed). Numeric street names should not be spelled out and may or may not contain a st, nd, rd or th after the number. Street type is abbreviated as AVE, ST, HWY. Directionals is the term used to refer to the part of the address that gives directional information for delivery (i.e., N, S, E, W, NE, NW, SE, SW). Abbreviate directionals to the appropriate 1 or 2-character abbreviation. In Clay County, we use a post directional field, which means that the directional should follow the street type. Secondary address unit designators, such as apartment or suite should be included at the end of the delivery address line. The pound sign (Number ) should not be used if the correct designation, such as APT or STE is used.  Addresses on highways are arranged a bit differently than those on numbered streets. An address would read: 12345 HWY 9 N vs 12345 90 AVE S
• Last Line: Spell city names in their entirety. Format the last line with at least 1 space between the city name and 2-character state abbreviation. Two spaces are preferred between the state abbreviation and the zip plus 4 code.
