## Abstract

A system may be configured to allow for storage of location information regarding a set of user devices. The location information may be updated relatively frequently, and without introducing additional traffic into a wireless telecommunications network associated with the user devices. The location information may be made available to internal devices associated with the wireless telecommunications network and/or to external third party devices (such as banks, payment card processors, or advertisers) with user consent. Since the information is obtained and stored prior to requests, the location information may be provided, in response to requests, relatively quickly.
