![]() ![]() Report on the 909 area code in December 2001, which identified an additional 206,000 available phone numbers. The PUC released a report on the utilization of phone numbers in the 909 area code in November 2000, which identified 3.9 million available numbers.In December 1999, the PUC suspended all overlays previously approved in response to customer concern over the 310 overlay and requisite 1+10-digit dialing. An overlay assigns another area code over the same geographic region as the current area code. In 1999, the PUC approved a two-phase change: a geographic split and subsequent overlay.The 909 area code (Riverside and San Bernardino) was created when it was split from the 714 area code in 1992.Commission staff is assessing carriers' inventory levels to determine whether carriers should return more blocks to the 909 number pool. Number pooling rules allow carriers to maintain up to a 6-month inventory of available numbers. The PUC has reclaimed 70 prefixes throughout California and in 2002 convinced the two largest telephone companies to donate an additional 1,790 thousand-blocks throughout California, including additional blocks donated to the 909 numberpool. Number pooling allows for the assignment of numbers to carriers in thousand-blocks, groups of 1000 numbers, rather than whole prefixes or groups of 10,000 numbers. The Commission is continuing to petition the Federal Communication Commission (FCC) for additional authority to pursue more ambitious number conservation measures, such as a specialized overlay area code for non-geographic phone numbers (numbers used for fax machines and data transmission) and more aggressive number pooling, while planning for the eventual need for new area codes in the 310 and 909 areas. The number conservation rules have also allowed carriers to continue to receive phone numbers to serve new customers in the 310 and 909 area codes three years after the previously forecasted expiration dates of these area codes. These rules have staved off what appeared in 1999 to be the necessity of adding 16 new area codes to California's roster of 25 area codes. In an effort to preserve area codes and minimize costs to homes and businesses of changing phone numbers, the California Public Utilities Commission (PUC) is monitoring compliance by telecommunication carriers with the telephone number conservation rules the Commission has implemented during the past three years.

April 5 at the Redlands Community Center, 111 W. April 4 at the Ruben Campos Community Center, 1717 W. The San Bernardino meeting will be 6 p.m.The CPUC plans to hold three local meetings to discuss the potential changes and to hear any concerns: “Just about everybody had a cellphone, and it was difficult to keep that up to date,” said Godwin, who added she was happy to hear the CPUC plan is to use the overlay method for new numbers. She recalls the nuisance of having to verify employee contact numbers for those who had suddenly disappeared from the 909. The associate professor of Public Administration at the University of La Verne was working for the city of Chino at the time, girding its emergency preparedness plans. Marcia Godwin remembers the hassle back in 2004, when the 951 area split from the 909. “So I think there’s been more thought put into it this time around and more consideration of what the impact is.” “The hardship was having to change the numbers, ergo, change everything that occurs in business: your envelopes, your returns, invoicing and everything that goes along with it,” Thurston said in a phone interview. Kathie Thurston, executive director of the Redlands Chamber of Commerce, remembers the difficulties businesses faced when the 909 was born. “It is definitely an inconvenience for businesses to change their phone numbers.” “It’s much better this way,” Penman said in a phone interview.
