Abstract
A contact update system augments contact telephone numbers with an appropriate country code. The system may receive a contact telephone number that lacks a country code. The system can then determine the country code of the contact’s telephone number using various heuristics. The heuristics may include the contact’s association with other users (e.g., the contact’s comments on social networks, location of the contact, call/message history with the contact, or social graphs). The system can update a record of the contact telephone number by adding the determined country code to the received telephone number.
