Cuccia" Subject: 500-NXX Assignments Pat: This is a list of the 500-NXX Code assignments, as of 30-June-1996. It is from a downloadable .zip file at the FCC's website. The URL for the FCC document: LONG DISTANCE CARRIER Code Assignments Industry Analysis Division Common Carrier Bureau Federal Communications Commission October 1996 which also includes the following NANP assignments: (all as of 30-June-1996) 900-NXX codes CIC assignments (fg.D 10[1X]XXX and fg.B 950-xxxx) 555-xxxx line numbers The various lists are in both numerical order by code, and in alphabetical order by carrier/entity. There are also statistical charts showing code assignment activity over periods of time. Most of the extracted files are .wp spreadsheets. The entire .zip file is at the FCC-CCB State-Link site: www.fcc.gov/Bureaus/Common_Carrier/Reports/FCC-State_Link/fcc-link.html Scroll down and click on "Telephone Numbering Facts" to locate this particular .zip file, two different 1994 editions of code assignments, and other numbering/code information. These code/numbering assignments themselves came from Bellcore-NANPA. The 900-NXX list isn't all that long, and at a later date, I may submit it (converted/formatted in ASCII text, of course), but the CIC assignments and the 555-xxxx assignments are *way* too long for me to convert/format in ASCII text. The 555-xxxx line-number assignments do indicate if an -xxxx assignment is NANP-wide or 'regional' ... but for the 'regional' assignments, it does NOT indicate *which* NPA(s) the particular 555-xxxx is assigned for use in. So, here is the 500-NXX assignment list as of 30-June-1996.

TURNER & ASSOCIATES, INC. 987 AGT MOBILITY, INC. 988 WEST TENNESSEE TELEPHONE CO. 989 ORION TELECOM The SAC NPA 500 is for "Personal Communications", which (at least) AT&T and MCI are using for "Personal" or "Follow-Me" Numbers. Other carriers might be using them for other functions, sometimes even something similar to 900 PAY-per-call! :( There is a *recent* INC (Industry Numbering Committee) issue (#114) about the exhaust of 500-NXX resources, downloadable in MS-Word from the ATIS' website: ftp://ftp.atis.org/pub/clc/inc/114.doc NANPA is *presently* reporting that 568 individual assignments/reservations of 500-NXX codes have been made, 72% of the total 500-NXX resource. (The list above is somewhat less than 568 individual code assignments, however). SAC NPA's 533, 544, 566, 577 and 588 have been reserved as "easy-to-recognize" codes for expansion of Personal Numbering, for about three years now. 522 is not presently available for additional Personal Numbering, due to conflict with billing use of 52X-XXX codes for identifying ratecenters and ratebands of Mexico (CC +52), since US Carriers bill calls to Mexico based on distance between ratecenters. 555 cannot be used as an expansion NPA code for Personal Numbering, due to confusion with (NPA)-555-xxxx numbers. The INC NPA guidelines indicates 555 as NOT ASSIGNABLE as an NPA. (The N11's, 555 and 950 are all noted as NOT ASSIGNABLE as NPA's). 511 is reserved as a three-digit 'short-code' and won't be assigned as a Personal Numbering SAC NPA (at least not as far as the present numbering guidelines/documents are written). And, of course, 599 is not available due to it being a N9X code for expansion of the NANP ten-digit format into a longer-length format. There is presently no portability between carriers in the 500 (nor 900) area. The FCC has requested that 500 and 900 portability be looked into by the industry, at least for portability of 500 and 900 service provided by *local* telcos, but not between inter-exchange carriers. I don't know what the present status of that is. So, just like we started to see toll-free 888 numbers last year, and then we might see 877 toll-free numbers this time *next* year, we soon might also begin to see SAC 533 personal numbers.
