Improving Location Estimation Results

If location estimation results don't appear correct, we can attempt to delete access point information from the PlaceEngine database and register the correct position(s) for you. When requesting the deletion of access point information, please make sure you supply us with the MAC address(es) of the relevant access point(s).

Please be aware that there is no guarantee that deleting and reregistering an access point will improve location estimation accuracy. Also please be aware that we reserve the right to refuse to any deletion request.

Obtaining your MAC address

Most access points have the MAC address printed on a special seal on the underside of the access point. A printed MAC address can take any of the following forms:
