You may use this service from any off-campus phone by following the simple dialing instructions found on the back of this calling guide or the back of your Authorization Code card. An advantage to the STS service is its individualized billing, which will provide you with an invoice of your calls only. The one Authorization Code you are assigned may be used from any on-campus residence hall phone or any phone off campus. Follow the instructions found on the back of this calling guide or your Authorization Code card. I have not returned my STS Registration Card to the STS office.
