Permission Number

A permission number (also known as an “add code”) is a 5 or 6-digit number given to students, by the instructor or department of the course, which enables the student to enroll in a course.

Students can obtain permission number by contacting instructor in person, via phone or email. If an instructor is not listed for the course, contact the department offering the course.

Permission numbers are needed when:

  • MySJSU notes "instructor or department consent is required".
  • MySJSU notes "you do not have the prerequisite(s) for a particular course when you attempted to register". If you have completed the course prerequisite, submit an unofficial transcript as proof to the instructor.
  • Class is closed/ full

Exceptions: Permission numbers can not override these two requirements:

  • WST passing
  • Upper Division Standing (Junior class level, earned 60 or more units)

How to add a class with a permission number (If you are on waitlist, you will need to drop yourself from waitlist first):

  • Go to MySJSU and start the process to add the class as usual.
  • After selecting the class, you will see a box to enter a permission number:

Permission Number box

  • Put the permission number in the box and finish the enrolling steps.
  • Check your class schedule to make sure you added the class successfully.
  • If needed, see step by step with screenshots at Tutorial how to add a class [pdf].


  • Permission numbers are given at the discretion of the instructor or department.
  • A unique permission number must be issued to each student
  • Permission numbers do not expire until successfully used by add deadline. See most current Registration calendar for the current date.
  • A permission number is only valid for one specific section of the course.  If you want to change sections, you will need a new permission number.
  • Permission numbers can not override time conflicts. Students must submit a Time Conflict Consent Request (DocuSign) from the instructor of the class that student has not yet enroll. Registrar's Office staff will enroll the student.
