Why You Might Need a 911 Address Change Letter (and How to Get One)

A 911 address change letter is issued by your local Addressing or Mapping Department (often part of the county’s Emergency Services or Planning office). It documents the transition from a rural-style address (like RR or HCR) to a city-style format (house number and street name) for emergency response accuracy.

📌 How to Get the Letter

• Contact your county’s 911 Addressing Office: This is usually the department responsible for assigning and updating physical addresses. You can call or visit their website to request documentation.

• Provide identifying details: You may need to confirm your property location, parcel number, or previous address.

• Request the formal letter: Ask for a letter that includes both the old and new address for your records and for notifying utilities, banks, and other services.

For example, in Yancey County, NC, the 911 Addressing Department provides a letter with both addresses when a change is made due to road range inconsistencies.

📬 Who to Notify

Once you receive the letter, you should inform:

•   USPS (though mail may still be delivered to the old address for a time)

•   Utility companies (electric, water, cable, etc.)

•   DMV (using the appropriate form, like DMV Form 232 in NY)

•   Tax office, insurance providers, and any other relevant contacts

🛠️ If You Haven’t Received One

If you suspect your address has changed but haven’t received a letter:

•   Check with your county GIS or Planning Department

•   Look for local announcements or mailers regarding 911 readdressing

•   Ask neighbors if they’ve received similar notifications
