A user device acquires identifiers and signal strengths corresponding to detectable wireless devices. The user device associates one or more of the identifiers with one or more venues, assigning a confidence value to each association. A score value is also assigned to each association based on the signal strengths and the confidence values. One of the associations is selected based on the score values, and is designated as the most likely venue where the user device is located. Information may be accessed or requested, or one or more operations may be performed, in accordance with the most likely venue.
