N.C. Gen. Stat. § 143B-1411

Each CMRS provider must provide its 10,000 number groups to a PSAP upon request. This information remains the property of the disclosing CMRS provider and must be used only in providing emergency response services to 911 calls. CMRS communications service provider connection information obtained by PSAP personnel for public safety purposes is not public information under Chapter 132 of the General Statutes. No person may disclose or use, for any purpose other than the 911 system, information contained in the database of the telephone network portion of a 911 system.
