US Telephone Number Anatomy
Format: (NPA) NXX-XXXX
NPA = Number Planning Area (Area Code)
NXX = Central Office Code (Prefix/Exchange)
XXXX = Line Number
N digit can be any number from 2 to 9
P, A, X can be any number from 0 to 9
Ex: (571)
571 Area code assigned in Virginia
434 Identifies Exchange assigned to a Telco within a specific Rate Center using a specific telephone company switch

5. Local/Wireless Number Portability Overview

Local/Wireless Number Portability Overview
The Telecommunication Act of 1996 defined "number portability" as "the ability of users of telecommunications services to retain, at the same location, existing telecommunications numbers without impairment of quality, reliability, or convenience when switching from one telecommunications carrier to another
The Telecommunications Act of 1996 established a "competitive checklist" that required the Bell Operating Companies (BOCs) to be in full compliance with the FCC’s LNP regulations in order to provide in-region inter-LATA services. The Bell Operating Companies were not permitted to offer long distance service until such time that LNP had been implemented in their service areas.
Bottom line: Business and consumers can now switch their local telephone carrier without having to change their telephone number.

2. Request to Validate Subscriber Information
*Note: The Old Service Provider may NOT approve the port and place the Pending Port in “Conflict”, which, typically requires “verbal” interaction between the new and old service providers. If the consumer or business changes their mind and does not wish to port, the Pending Port may be “Cancelled.”

7. Telephone Number Use Before LNP, the telephone number:
Identified the state to which it is assigned
Identified the rate center to which it is assigned
Identified the service local/wireless carrier who serves the number
Identified the underlying technology (wireline or wireless) associated with the number as derived by knowing the type of carrier
Used solely by telephony network to set-up and route calls
Used solely by mobile networks (if a mobile TN) for roaming registration and validation
After LNP, the telephone number:
Still identifies the state to which it is assigned
Still identifies the rate center to which it is assigned
*No longer identifies the service local/wireless carrier who serves the number
*No longer identifies the underlying technology (wireline or wireless) associated with the number as derived by knowing the type of carrier
*No longer is used solely by telephony network to set-up and route calls
*No longer is used solely by mobile networks (if a mobile TN) for roaming registration and validation

8. Some Telephone Numbering Facts
In the NANP (North American Numbering Plan), 325 area codes have been assigned covering over 100,000 working prefixes/exchanges (source NANPA)
In the US, there are estimated to be 600+ million working telephone numbers
LNP (Local Number Portability) has been available in the top 100 MSAs (Metropolitan Statistical Areas (these are defined by the Census Bureau)) since 1997 for wireline telephone numbers
WNP (Wireless Number Portability) has been available in the top 100 MSAs since November 24, 2003 for wireless numbers
There have been over 37 million wireless telephone numbers ported. (Source FCC)
Over 2.8 million telephone numbers have been ported from wireline carriers to wireless carriers (Source FCC)

9. FCC TCPA Regulatory History
In December 1991, Congress passed the Telephone Consumer Protection Act (TCPA) in an effort to address a growing number of telephone marketing calls and certain telemarketing practices thought to be an invasion of consumer privacy and even a risk to public safety.
In 1992, the FCC adopted rules implementing the requirements of the TCPA. The TCPA specifically prohibits calls using an auto-dialer or artificial or prerecorded message “to any telephone number assigned to a paging service, cellular telephone service, specialized mobile radio service, or other radio common carrier service, or any service for which the called party is charged.” Note: Courts have interpreted the term “automated telephone dialing systems” broadly to include equipment that is capable of automated dialing, whether or not that capability is being used.)
In July 2003, the FCC rejected a proposal to create a “good faith” exception for inadvertent autodialed or prerecorded calls to wireless numbers finding there are adequate solutions in the marketplace to solve the problem.
In September 2004, the FCC established a limited safe harbor period in which persons will not be liable for placing autodialed or artificial or prerecorded message calls to numbers recently ported from wireline to wireless service. The FCC concluded that callers will not be in violation of 47 C.F.R. § (a)(1)(iii) for autodialed or artificial or prerecorded message calls placed to a wireless number that has been ported from a wireline service within the previous 15 days, provided the number is not already on the national do-not-call registry or caller’s company-specific do-not-call list. The 15-day safe harbor period runs from the time the port has been completed and the number appears in Neustar’s “Intermodal Ported TN Identification Service” as a wireless number.
Bottom Line: Calls placed using auto-dialers or made with artificial or prerecorded messages are prohibited to wireless phones without the prior express consent – which must be written in certain cases – of the then-current subscriber. There is, however, a 15-day safe harbor period in cases where a telephone number is ported from a wireline to a wireless service. Posting of the telephone number in Neustar’s Intermodal Ported TN Identification Service starts the 15-day safe harbor period clock.
