Follow these instructions if you have a problem caused by a mapping error in most GPS devices/apps and online maps. For example:

If your problem doesn't quite fit this description, return to the main Address, Route, and Map Problems page. Go there

1 Submit a correction online

Visit the following websites to report the mapping error directly to the companies and organizations that maintain digital maps. To reach the most GPS users, we recommend reporting the same problem at each of these websites.

The websites above are not run by the government and may require registration and/or browser plug-ins. We list them for information only and do not endorse any non-governmental products, services, or views.

If you are a business, consider hiring a firm that can correct and maintain your location information across multiple mapping systems on your behalf. An internet search for "business location data management" should point you in the right direction.

2 Contact your local addressing authority

Your local county or municipality is responsible for maintaining your authoritative street address. By working with them, you should be able to correct how your address appears on maps used by 911 call responders and your post office, and possibly in the National Address Database. The National Address Database is a composite of authoritative addressing information submitted by participating U.S. states (view list at and select counties. Some map makers, such as Google, use the National Address Database to update the address data found in navigation devices, apps, and online maps.

Most counties have a 911 addressing coordinator that may be found on your county's website that is responsible to update information on address changes or to resolve address issues. If the 911 addressing coordinator cannot be found on the county website, then you can contact the non-emergency number for the county to ask for the appropriate addressing authority. You can also go to: and select the state in which you live. The person responsible for operating the state 911 system will be identified, and they should know who you should talk to at the local government level.

3 Wait patiently

After you submit a problem report, it may take weeks or months for each map provider to verify it and issue a mapping software update.

Once an update is issued, users of mobile apps and online maps will see it immediately.

However, people with dedicated GPS devices, such as car navigation systems, will have to download the update to see the change. Unfortunately, most people do not update their devices regularly.

4 Understand

Please understand that the U.S. government cannot correct mapping errors in consumer devices and apps. The government's GPS satellites are simply beacons, like lighthouses, that devices use to calculate their own latitude and longitude. The satellites do not transmit any mapping information.

The private sector is responsible for maintaining the mapping information in consumer devices/apps and online maps. For further help with devices, apps, and maps, please contact the companies that produce them.
