Authorization Codes

An authorization code is required for all billable long distance calling from OSU extensions. Authorization Codes are seven digits in length. Each authorization code is assigned a Facilities Restriction Level (FRL). The FRL will designate what long distance calls can be made and their routing priority. The FRLs are as follows:

  • Oregon
  • United States, Canada, and misc. locations reached by dialing an area code
  • All locations including international calls.

Authorization Codes should be kept private and confidential.
