FCC Limitations for Business and Residence Referral of Calls

The following information applies to the TC PER field for all regions:

Effective July 17, 2000 per FCC Mandate, Docket #99-200, Number Referral Service will be limited to a maximum of:

  • Business: 365 Days
  • Residence: 90 Days

For Business customers: If the life of the directory is more than 12 months, the Number Referral Service will end after 365 days.

There may be areas where the length of time is shortened due to the rapid depletion of telephone numbers. In these cases, Number Referral will be limited to a maximum of:

  • Business: 270 Days
  • Residence: 60 Days


NO EXTENSION will be granted even if the CLEC wishes to pay for it. The FCC has ordered all telecommunication companies to limit Number Referral Service.
