# CDR012 - NANP Originating numbers must have valid a NPA NXX

Override is allowed

| Name | NANP Originating numbers must have valid a NPA NXX. |
| --- | --- |
| Common Cause | The originating number in this usage record is an NANP number whose NPA/NXX is invalid. |
| Common Resolution(s) | Actions you can take to resolve the problem: - This NPANXX may have been just recently put into service. If this is the case, contact IDI BCT to reload the NPANXX table with the newest industry updates. - If the CDR contains a valid origination number, contact IDI for possible software (parser) updates – this may be improperly classified as NPANXX. - If this rarely occurs, the CDR may be bad or malformed. If so, it can be left alone (it will eventually age and no longer be visible) - or it can be purged immediately if desired. - If the usage record should be billed anyway, choose Override Rule on the usage record. If this is done frequently, consider a change to Unbillable Rules for this Unbillable Code. Note that ignoring lookup failures can have undesirable downstream repercussions including rating and discounting failures and poor invoice presentation. |
| Details | NANP originating number derivation logic populates originating place information (city, state, LATA, OCN, Latitude, Longitude, etc.) in the usage record with the results of a search against the NPANXX table. (7 digit o***riginating numbers are not subject to this check; only 10 digit NANP originating numbers***). In this case, the NPANXX in the originating number could not be found in the NPANXX table. |
