Area code was originally assigned to the entire state of Nevada, as one of the original numbering plan areas established in October Q: Why an overlay?
Q: Who will be affected? Q: What will be the new dialing procedure? Q: When will the change begin? Q: What will you need to do? Q: What will remain the same? A: The following will remain the same when the change goes into effect: Your telephone number, including current area code, will not change. What is a local call now will remain a local call regardless of the number of digits dialed.
A portion of these unavailable numbers can be used more efficiently if the recommendations contained in this report are implemented. The CPUC asked 49 companies, holding prefixes 6. Table shows the distribution of these prefixes by type of carrier; incumbent local exchange carrier ILEC , competitive local exchange carrier CLEC , 15 and wireless carrier. Of the 49 companies in the area code, 47 submitted utilization data. Although one company submitted data too late to be included in the summaries provided by NeuStar, TD has considered this late filer in its analysis.
A list of the companies that have been allocated numbers in the area code appears in Appendix A The remaining two companies holding six prefixes in the area code are no longer offering service in the area code.
The area code has 3. Of these unused numbers, TD found that companies held 2. The remaining 1. The summary of available numbers is shown in the table below.
Type 1 Carriers 17 , Total Available Numbers in the Area Code 3,, Not all of the 3. As shown in the table below, the CPUC could shift 0. Current technology requires a company to be LNP capable in order to donate numbers for another company to use.
All wireline carriers in the area code are required to be LNP capable. However, not all of these , numbers can be retrieved from companies' inventories because companies need to have enough numbers to meet anticipated future need. TD will not know how many of these , numbers will be available for pooling until companies submit their pooling block donations to the pooling administrator, which is scheduled to occur on May 4, The difference between the potential maximum , currently poolable numbers that wireline carriers hold and the , numbers estimated as likely to be donated to the pool consists of , numbers that companies are estimated to need for their six-month inventories.
The remaining , of the 1. However, companies can immediately use these numbers to provide service to their customers or meet other needs. Special-use prefixes 27 are generally not LNP capable, and constitute 10, of the 1.
Wireless carriers hold , unused numbers in the area code. Until wireless carriers become LNP capable in November , none of these numbers may be reallocated to other companies.
In the interim, wireless carriers may assign these numbers to their own customers. TD analyzed the utilization data to determine the availability of numbers within blocks of different contamination rates, to assess different contamination thresholds that could be employed in the number pool.
The following table summarizes available numbers by contamination level by rate center for wireline carriers. The first two numeric columns of Table show the potential numbers available to the pooling trial, except for those numbers kept for companies' six-month inventory, under current rules.
Available numbers in one rate center cannot be used in another rate center. Table shows that all rate centers except Hollister, Salinas, and San Antonio have available numbers that companies could donate to the pool. The first two of these three rate centers are no longer located within the present boundaries of the area code; they will continue to serve wireless customers who chose to retain their area code number when the area code split from , but will no longer be exerting demand for prefixes in the area code.
Thus, there should be no demand from wireline companies for prefixes in these rate centers. TD cautions that, although Table shows potential results from increasing allowable contamination levels, further analysis and input from the industry may be necessary to determine accurately the quantity of additional blocks that could be added to the pool while still leaving companies with a six-month inventory.
Table shows available numbers in blocks of differing contamination levels held by wireless carriers. TD staff is investigating whether there are methods to make some of these , unused numbers available to other carriers despite the FCC's exemption of paging companies from becoming LNP-capable.
These instances are a small proportion of the 6, blocks in use in the area code, and do not necessarily indicate that companies have intentionally contaminated blocks to avoid having to donate them to the number pool.
Viewing the utilization data suggests, however, that companies have not generally followed practices of sequential numbering and filling blocks substantially before using new blocks. The CPUC's rules on sequential numbering and fill rate practices promulgated in Decision are designed to ensure that companies efficiently use their numbers in the future.
Where companies possess significant available numbers in a given rate center, these two efficiency measures could prevent the opening of new blocks or prefixes. Companies reported utilization data as of April 30, The sequential numbering and fill rate decision was issued in July Therefore, TD does not expect companies to continue contaminating blocks unnecessarily.
Decision directed companies to return prefixes that are held unused for more than six months. Of these unused numbers, , are in 17 whole prefixes that are completely uncontaminated, i. The following table shows the breakdown between wireless and wireline carriers. Total Avail. The , numbers in 17 spare prefixes can possibly be reclaimed if not used within six months. The FCC granted authority to state regulatory commissions to investigate and determine whether prefix holders have activated prefixes within the allowed time frames, and directed the NANPA to abide by the state commission's determination to reclaim a prefix if the state commission is satisfied that the prefix holder has not activated the prefix within the time specified in the first NRO Order.
In this ruling, the CPUC instructed the delinquent companies to comply immediately. Companies are to inform the CPUC either that the prefix es have been placed in service or returned, that the company was incorrectly included in the NANPA's delinquent list, or the reasons the prefix es have not been placed in service. The CPUC will review the reasons and make a determination as to whether the prefix es must be returned or reclaimed by the NANPA, or whether to grant an extension of time to the company to place the prefix es in service.
Any delinquent company that fails to comply will be subject to penalties and sanctions. In the following sections, the TD recommends a series of policies designed to require companies to use unavailable numbers more efficiently. These policies would potentially free more numbers for use in the pool, to be allocated through the monthly lottery, or to be used otherwise by companies.
Companies report that 3. Companies commonly refer to these numbers as "unavailable". Unavailable numbers include not only those actually in use by customers, but also the following categories:. These policies would potentially free more numbers for use in the pool, to be allocated through the prefix lottery, or to be used otherwise by companies. In the area code, there are 3. The percentages of assigned numbers to total numbers held by companies are shown in the table below.
Assigned Numbers to Numbers Held by Companies in millions. Assigned Numbers Nos. Held by Companies Percentage. Non-working wireless describes numbers assigned to wireless customer equipment, but which are not yet working.
These numbers are considered a sub-category of assigned numbers. For example, wireless carriers sometimes pre-package a cellular telephone with an assigned telephone number for sale to customers. Although the number is assigned, it will remain inactive until a customer purchases the telephone. Only one company reported 8, assigned numbers in the non-working wireless category for the area code.
While the quantity of non-working wireless numbers reported generally is low, this sub-category of assigned numbers could increase because there are no restrictions on the number of days that a wireless company can hold these numbers, causing numbers to remain idle for an unspecified period. The CPUC should consider several options to improve inventory management of non-working wireless numbers.
One option is for the CPUC to require companies to return these numbers to the unassigned category after days similar to the requirement the FCC has established for reserved numbers. Recommendations for Treatment of Non-Working Wireless. Under these INP arrangements, two telephone numbers are associated with each customer. LNP eliminates the need for two telephone numbers for each customer when the customers change companies, because customers can take their numbers with them.
Since the area code is included in one of the top MSAs in the nation, all wireline carriers in should be LNP-capable. They reported a total of INP numbers in the area code.
Since all the reported INP numbers were from ILECs and none were from their competitors, it does not appear that INP exists in the area code to facilitate competition for customers. Historically, the telecommunications industry has designated certain prefixes for special uses, usually to an ILEC.
These include numbers for recorded public information announcements such as time-of-day and weather forecasts, high-volume call-in numbers, and emergency preparedness 36 numbers. These prefixes are not made available for general commercial use, and thus, numbers within these prefixes that are not in actual use lie vacant. In , companies decided not to duplicate the special-use prefixes in each area code.
Concerned that this process could adversely affect the public, the CPUC directed that these prefixes should be duplicated in each new area code. The utilization study shows that four prefixes are dedicated for special uses; one each for directory assistance, high-volume calling, time, and emergency preparedness.
Excluding high-volume calling, companies reported 30, unavailable numbers in three special-use prefixes. TD questions the necessity of assigning an entire prefix for each purpose. Furthermore, having multiple special-use prefixes is an inefficient use of numbers in the area code as well as in other area codes in California. For example, if the prefix, currently reserved only for directory assistance, 37 could be used to provide time and emergency preparedness service, then two more prefixes could be returned for reallocation in the area code.
Similarly, expanded use of the prefix throughout the state could result in more returned prefixes in other area codes.
The CPUC should further analyze the option of obtaining standard numbers in every California area code to provide time, emergency preparedness, and weather information at no additional cost to customers.
Recommendations for Special-Use Prefixes. Where the numbers are presently assigned randomly, TD recommends that these numbers be moved and consolidated in one thousand-block in order to free more blocks for number pooling.
Carriers "set aside" numbers for future use by customers. This utilization study incorporated the FCC's day requirement. The FCC later issued an extension until December 1, for companies to comply with the day rule.
This took effect on December 29, Wireline carriers reported a total of about , reserved numbers in the area code. If the quantity of reserved numbers held by wireline carriers can be minimized, additional numbers could be available for immediate use by the companies from within their own number inventories, thus slowing the rate at which new prefixes are allocated to these companies. Numbers could also be freed up for reallocation in the number pool, once established.
Similarly, companies are not required to use their reserved numbers stock before they can request that new numbers be allocated to them. Comparing the data on the San Martin rate center and the Campbell rate center illustrates wide discrepancies between the quantity of reserved numbers companies hold.
Wireline carriers reserved over 17 times as many numbers as a percentage of numbers held in the latter rate center. Other companies in that same rate center hold as few as zero reserved numbers. If the CPUC orders efficient use practices specific to reserved numbers, more numbers could be made available for customer use. Wireless carriers reported nearly 10, reserved numbers in the area code. Wireless carriers also reported wide variances in reserved numbers.
In the San Jose South rate center, two wireless carriers reported no reserved numbers. Why should I get an area code number? Richard Bagnell. Your email address Subscribe.
