Earliest code activation date - February 27, 2005 First date codes may be ordered through NANPA

Number: PL-334 Date: December 12, 2003 Subject: 909 NPA; 2-way Split, Creating 951 NPA California Related Previous Planning Letters: 189, 206 and 215 General Description On November 13, 2003, the California Public Utility Commission (CPUC) in Decision D03-11-022 approved a 2-way geographic split as the relief method for the 909 NPA, which serves the south-western portion of San Bernardino County, the western portion of Riverside County and a small portion of Los Angeles County in southern California. A copy of the CPUC order and other related Commission information can be obtained at: http://www.cpuc.ca.gov/. This PL supercedes PL s # 189, 206 and 215. As ordered by the Commission, the northern region of the existing 909 NPA will retain the 909 designation after the split. Some of the areas that will continue to be served by the NPA 909 include such communities as Arrowhead, Big Bear City, Big Bear Lake, Calimesa, Chino, Claremont, Colton, Crestline, Diamond Bar, Fontana, Ontario, Pomona, Redlands, Rialto, Running Springs, San Bernardino and Upland. These communities will retain the 909 NPA. The new 951 NPA will serve the southern portion of the existing 909 NPA. Some of the areas to be served by the new 951 NPA will consist of such communities as Anza, Arlington, Banning, Corona, Elsinore, Hemet, Idyllwild, Mira Loma, Moreno Valley, Murrieta, Perris, Riverside, San Jacinto, Sun City, and Temecula. These communities will change to the 951 NPA. Implementation of Relief Plan Implementation of the split of the 909 NPA is as follows: Start of permissive dialing and latest date for all carriers to activate new NPA code End of permissive dialing and start of mandatory dialing of the new NPAs Earliest date for the end of recorded announcement Time Date 12:01 AM Pacific July 17, 2004 12:01 AM Pacific October 30, 2004 - February 27, 2005 Earliest code activation date - February 27, 2005 First date codes may be ordered through NANPA - August 27, 2004

During the permissive dialing period, either the 909 or the new 951 NPA code will be acceptable in a dialed number terminating in the new 951 NPA. After the permissive period ends, all calls dialed with the incorrect NPA code will be routed to intercept recording through February 25, 2005. The CPUC directs carriers, to the extent possible, to continue playing the special recorded announcement instructing the caller to dial the new 951 area code for one year following the end of the mandatory dialing period, or until such time as the prefix is assigned in the 951 area code. Central Office Code Listings and NPA Map Attached is a listing of the central office codes, rate centers, and Common Language Location Identifiers (CLLI) that will remain in the 909 NPA and those that will move to the new 951 NPA. The CPUC order states they will not require paging type NXX codes to change to the new NPA. Additionally, the special use 853 NXX code (time service) and the 431 1 NXX code (High Volume Call In) will be duplicated in the new 951 NPA. This information is current as of December 10, 2003. Since NXX information may change over time, please consult the Local Exchange Routing Guide (LERG) or the NXX Activity Guide (NNAG) for updated information. Information in the LERG and NNAG is available by license contract from Telcordia Routing Administration (TRA), at 732-699-6700. The attached map identifies the NPA boundaries after the 2-way split. Dialing Plan At the beginning of mandatory dialing on October 30, 2004, the dialing plan for the 909 and 951 NPAs will be as follows: Type of call Call terminating to Dialing plan Local or Toll call Operator Services Credit card, collect, third party Home NPA (HNPA) *1+10-D HNPA Dialing is Optional Network Testing Foreign NPA (FNPA) HNPA or FNPA 7-digits (NXX-XXXX) or 1 + 10-digits (1 + NPA-NXX-XXXX)* 1 + 10-digits (1 + NPA-NXX-XXXX) 0 + 10-digits (0 + NPA-NXX-XXXX) All international and domestic carriers should ensure that the new 951 NPA has been activated throughout their networks prior to July 17, 2004. The test number to verify the routing to the new NPA will be in service beginning May 17, 2004, through November 30, 2004. The test number to verify the routing to the 951 NPA is (951) 951-0951. A recorded announcement will indicate that the test call has been successfully completed. 1 Subsequent to the Order the CPUC clarified the 431 NXX as the correct code for duplication. 2
