At 2 a.m. this morning, the telecommunications industry followed through on a New Year's resolution that will affect users and callers of cellular phones or personal handy-phone systems nationwide.

To accommodate the ever-growing pool of portable phone users, cellular and PHS phone numbers have been expanded from 10 to 11 digits. All cellular phone numbers now begin with the prefix 090, followed by the second digit of the original phone number and its seven final digits. For example, the number 040-555-5555, would become 090-4555-5555.
