Information About

Mobile Caller Id




Number-only Caller ID, or the display of an incoming number not previously programmed into a users handset, has become less useful to mobile users as the number of area codes has increased in recent years, and continues to grow. Since 1995, the NANP has added over 150 new area codes, bringing the total to over 350 and over 125,000 unique exchanges in North America alone.

Currently, city and state mobile Caller ID is the first enhancement in wireless Caller ID technology in nearly a decade.
