Abstract
A system and method for updating physical address location information of a wireless device for E911 services. The updating may include determining that the current geographical coordinate location of the wireless device has moved beyond a predetermined distance from a last recorded geographical coordinate location. A physical address location associated with the current geographical coordinate location may then be updated. The physical address location may be updated in the wireless device and/or a data repository operating on a data packet network. The physical address location may be communicated to a public safety answering point (PSAP) in response to an emergency 911 call being placed.
