Domino's has been using Caller ID since last year, when the company upgraded its computer system in all 700 corporately owned stores. Approximately 1,000 of the 4,000 Domino's franchise stores are also using it. The system makes sense for a company like Domino's because of its high volume of calls. It now takes an average of 15 to 20 seconds to place an order, whereas before it was close to 45 seconds to 1 minute. Federal Express, another high-volume company, has been using caller identification since 1993.
