Problems and Issues Management
In late 1999, the LNPA WG established a "problem identification and management process" (PIM) for LNP issues. The LNPA WG is not responsible for resolving all LNP problems. The LNPA WG does an initial evaluation of each LNP problem submitted, then either develops a resolution for the issue or refers the issue to the appropriate forum for resolution. The status of each LNP issue submitted is reported to the NANC on a regular basis.
The LNPA WG has developed issue submittal guidelines, an issue submittal form, process flows, and a tracking mechanism. Issues should be submitted to the LNPA WG, using the issue submittal form, at least two weeks before the LNPA WG meeting at which LNP issue's discussion is desired.

Additionally, Trading Partners should provide 30 days notice of planned porting outages. If 30 days is not possible, a minimum of 14 days notice should be provided.

Socket Telecom ("Socket") is attempting to port numbers away from a LEC to serve a customer that wishes to change its local service provider. Socket will be replacing the customer's current local exchange service with a tariffed Out of Calling Scope Service (either Remote Call Forward or Foreign Exchange Service) in conjunction with Socket's local exchange service. The LEC that is currently serving the customer is refusing to port the number on the grounds that the definition of number portability as defined in Section 147 U.S.C. 151 (30) is specifically defined as excluding attempts to change the serving location of the customer. The LEC is calling this "location portability" and is taking the position that it has no obligation to port a number if the customer's service location will change as a result of the number port.

Some end users are unable to port their telephone numbers because the NXX code is not opened for portability in the NPAC SMS. Usually, this can be resolved by communication between the two service providers. However, in some cases the old service provider (OSP) contacts are not available, or the OSP refuses to make the code portable.

Carriers are taking back numbers that have been ported out several months or even years because their systems do not reflect a valid FOC was sent. In many cases they have not removed the number from their number inventory and they have re-assigned the TN to another customer.
