Analysis of information sources in references of the Wikipedia article "Local number portability" in English language version.
The FCC, on its own initiative and to implement a statute, has established operating rules that limit how carriers package services. The Commission also has imposed restrictions on what contractual service terms carriers can impose that have the effect of locking in consumers and foreclosing their ability to take service from a competitor. On the supply side, the FCC requires CMRS providers to allow local number portability, which is the ability of subscribers to retain the same telephone number when changing carrier services. [See Implementation of Section 6002(B) of the Omnibus Budget Reconciliation Act of 1993, Annual Report and Analysis of Competitive Market Conditions With Respect to Commercial Mobile Services, Eleventh Report, 21 F.C.C.R. 10947, 11005 (2006).] Such local number portability promotes competition by eliminating a disincentive to shift carriers. Local number portability, as discussed below, requires carriers to cooperate on the assignment and transfer of telephone numbers.
