Each utility is responsible for having the name, address, and telephone numbers of all of its customers listed in a telephone directory or electronic database, except public telephone and telephone service unlisted at customer’s request. A customer directory must be made available upon a customer’s request.

1. A. The telephone utility shall list its customers with at least one provider of directory assistance services or with its own directory assistance operators to provide the requested telephone numbers based on the customer’s name and address when such requests are made by communication users, except public telephones and telephone service unlisted at customer’s request.
2. B. At least one directory assistance provider used by the utility or the utility’s own directory assistance operators shall have access to records of all telephone numbers in the area for which they are responsible for furnishing directory assistance service except telephone numbers not published at customer’s request.
3. C. Each telephone utility shall make every effort to list its customers with at least one directory assistance provider used by the utility or the utility’s own directory assistance operators as necessary for the directory assistance operators to provide the requested telephone numbers based on customer names and service locations, and to provide updated information to the directory assistance provider as reasonably necessary to minimize “not found” numbers.
4. D. In the event of an error or omission in the name or number listing of a customer, such customer’s correct name and telephone number shall be corrected in the files of the directory assistance provider used by the utility, or the utility’s own directory assistance operators within a reasonable amount of time.
