The Assessor’s Office is responsible for the assignment and maintenance of addresses within Comanche County. This does not include residences within city limits. Each respective city will have its own office for addressing within city limits. Addressing is required for all residences within Comanche County. If you receive mail at a P.O. Box, or from another location, a 911 address is still required.

Frequently Asked Questions (FAQ)
Q: Why do I need a 911 address?
A: 911 addresses are used to give emergency responders an accurate location for your house. Without it, you or your loved ones will be waiting longer for responders to find you.
Q: I don’t receive mail at my house, do I still need a 911 address?
A: Yes. 911 addresses are used to give responders the exact location of your physical home should fire, sheriff or EMS services be required.
Q: How do they come up with my 911 address?
A: The Assessor’s Office uses Distance Based Addressing (DBA). Every 10.56 feet is a potential address. They start at the closest intersection and use the Distance Measurement Indicator (DMI) to measure the distance to the center of the driveway of a potential address. The resulting number is the address. Slight deviations are used to allow odd numbers on the south or west side and even numbers on the north or east side.
Q: Why do I have to stake out my driveway, or have a permanent driveway, before you will give me an address?
A: The driveway is the key point of the address. It is the only part of the residence that intersects with the road, and is therefore the only reference point to build an address from.
Q: Why do I have to notify the phone company if my address changes?
A: The Assessor’s Office maintains a database of all structures within Comanche County. They do not maintain information such as telephone numbers. Landline telephones are connected to 911 addressing, so the telephone company must be informed of a change of address. If your phone number is 580-555-5555 and you live at 5555 Main Street, if you move to 5555 Meridian Avenue, the telephone company will still think you are living at 5555 Main Street. Subsequently, a call from 580-555-5555 will send first responders to the previous address of 5555 Main Street.
Q: Why can’t 911 use rural route addresses?
A: Rural route addresses are only a point for the post office to deliver mail. It does not necessarily represent a structure or house and cannot be used accurately by 911 dispatch centers.
Q: Why has my mailing address changed?
A: The Federal Government has mandated that the post office use 911 addresses, so your mailing address may have changed to comply with that. 911 addressing represents a permanent address, as opposed to the rural route address which represents a drop off point.
Q: Why are the numbers so long?
A: The 911 addressing system needed to be understandable and allow for growth. The current addressing system allows for 1,000 addresses per mile.
