Authorization Codes:

All telephones at JLab are restricted to local calls only.  To place a domestic and/or international call, callers must obtain an authorization code.  Division approval is required for all authorization codes.  Staff Members may get approval from supervisors.  Users need to fill out the Long Distance Authorization Form for approval.  Please visit the User Liaison Office in CEBAF Center, Room L111. When dialing a number that requires an authorization code, listen for the series of beeps before entering it in. You may experience a brief pause before the call connects.
