How are addresses assigned?

McClain County 9-1-1 assigns addresses for all residences within the unincorporated boundary of McClain County, as well as several of the smaller communities within the county. We do not assign addresses for those within the Newcastle, Blanchard, Goldsby, or most of Purcell city/town limits and we do not assign addresses to vacant land. To determine whether you should contact 9-1-1 or another city for an address, please consult our Address Map.

The McClain County 9-1-1 addressing policy requires a road to be given a name if there are more than three residences, businesses, or industries accessing the same road, regardless of the length. Read more about road naming here.

Homes and businesses within McClain County, and any town following the county addressing system, receive a number based on their location along the road the structure faces. Each address is determined using GPS to ensure accuracy and precision when it is assigned. Structures on the North and West sides of a road receive odd numbers, and structures on the South and East side of the road receive even numbers.

How do I get an address?

Every home and business in McClain County should have an address. When you build a new structure or place any sort of residence on county land, you must first obtain a building permit to do so.  To get a building permit, you will need to contact the McClain County Emergency Management office. You will receive a 9-1-1 Address Application as part of your packet of information. You can contact them via:

Phone: (405)955-4600
Email: mcclain.em@gmail.com
Office: 1930 S Green Ave
            Purcell, OK 73010

Once you’ve received your County Permit Poster please post it clearly at the driveway entrance so that our office can determine your location. Please allow TEN (10) business days for your address request to be completed.

If you are buying or renting a property and do not know the assigned address, please contact our office.

What should I do with my address?

Many residents are unsure what to do once they receive a new address. First, post your assigned address clearly on your building and mailbox so that it can be seen. If you do not display your address, or some of the numbers are missing/faded, Emergency Responders may not be able to locate you quickly. Also, it is important to notify your local mail carrier that this is your new address to ensure that you receive your mail correctly. It is the responsibility of the resident to notify and change the address of any companies that may send mail to you (for example your phone bill, credit cards, bank accounts etc).

Reflective address markers are available through the McClain County OSU Extension Office.

Can’t find your address on Google/ Having a hard time getting mail delivered?

Residents within McClain County may have trouble finding their address on Google. The 9-1-1 System does not have anything to do with Google’s search engine. Our office tries to keep Google Maps as updated as possible but we ultimately do not have any power over what Google displays on their maps. You can contact our office for further information or send feedback to Google by following these steps.

Similarly, our office does not have any control over the location systems places like UPS or FedEx uses. If you are having any trouble receiving mail please contact your local Post Office.
