Waitlist Procedure

What should you do if you are on the waitlist?

Check your COS email frequently. If and when there is an opening in the class the computer system will notify you through your COS email. If you are having trouble with your COS email contact the Student Help Desk as soon as possible. It is best to do this immediately so it does not postpone you receiving your notification. Support is available by phone at (530) 938-5523 or email For current hours see the Student Help Desk page. Have your name, Student ID or Social Security Number and date of birth available for identification purposes.

You will have 24 hours from the time you receive the email to register for the class.

If you do not register in this time, your spot will be offered to the next person in line and you will need to get back on the waitlist.

Add Codes and How They Work

If you get instructors approval to add the course on the day the class begins or prior to census you will receive an add code (4 digits) from your instructor. Add codes can be processed two ways:

  1. through mySiskiyous or
  2. by taking the add code to Registration with an add/drop form.

To input the add code online, login to mySiskiyous:

  • Select the registration tab on the left hand side, and click on the add/drop icon (+).
  • Search for the class you are adding or find the class you are waitlisted for.
  • You will then be directed to a page where you will input the 4 digit add code.
  • Click on submit changes and you will be enrolled in your course.

To verify that you have successfully added your class contact Admissions and Records or look for your class schedule on mySiskiyous.

Please Note:

  • Please make sure that all fees have been paid and prerequisites have been cleared or you will be unable to complete this process.

If you do not get a notification prior to the first day of class you should go to the class. If you are in an online course you can contact your instructor via email. In either case if the instructor is able to add you he/she will provide you with an add authorization code to add the course.
