How to Register for Classes at ASU: Step-by-Step
ASU registration is mostly waiting, then a 90-second sprint. The students who get the schedule they want are the ones who did the prep before their window opened. Here is the whole process, in order, plus the errors that trip people up.
Short answer
To register for classes at ASU: find your enrollment appointment in MyASU, clear any holds, copy the 5-digit class numbers for the sections you want from ASU Class Search, then add them in MyASU the minute your window opens. Register early, because seats in popular classes go fast.
Key Takeaways
- 1Your enrollment appointment is a fixed date and time in MyASU
- 2Holds block registration, so clear them days before your window
- 3Prep your cart with 5-digit class numbers, including backups
- 4Register the exact minute your appointment opens for the best odds
- 5If a class is full, track it and get an alert when a seat opens

Step 1: Find Your Enrollment Date
ASU does not open registration to everyone at once. You get an enrollment appointment, a specific date and time, shown in MyASU under My Classes. Appointments are staggered, and students with more earned credits usually go earlier. Find yours and put it in your calendar with a reminder.
You cannot register one second before this window. So the goal is simple: be fully prepared and logged in when the clock hits your time.
Step 2: Clear Your Holds Early
A hold is the single most common reason a student watches their window open and still cannot register. Check the Holds section of MyASU now, not the night before. Common ones include:
- Advising holds (you need to meet with your advisor)
- Financial holds (an unpaid balance)
- Immunization or health holds
- New-student or orientation holds
Some of these take days to resolve. An advising hold can mean booking an appointment that is not available until next week. Clear them with time to spare.
Step 3: Build Your Cart With Section Numbers
Do not go hunting for classes during your window. Use ASU Class Search ahead of time to pick your sections and copy each 5-digit class number. Build a plan that includes:
- Your first-choice section for each class
- A backup section (different time or instructor) for each
- One alternate class in case a requirement is completely full

Step 4: Register the Minute Your Window Opens
When your appointment starts, log into MyASU, go to the add-class screen, enter your class numbers, and submit. Add your most competitive class first, because those seats disappear quickest. Every minute you wait, more students with the same window are grabbing the same seats.
Be logged in and on the registration page a couple of minutes early. Refresh right at your start time. The difference between getting a class and missing it is often under five minutes.
Common Registration Errors (and Fixes)
- “Hold on your record.” Go clear the hold in MyASU, then try again.
- “Requisites not met.” You are missing a prerequisite. Contact the department or your advisor for an override.
- “Time conflict.” Two sections overlap. Swap one for a different meeting time.
- “Class is full / closed.” No seats left. Track the section so you know the moment one opens (more below).
- “Department consent required.” Email the department for permission to add the class.
What If the Class You Need Is Full?
This is the moment registration falls apart for a lot of students. The required class is full, every section, and you are stuck refreshing ASU Class Search hoping someone drops.
Instead, hand that section to PickMyClass. It checks the class every 30 minutes and emails you the second a seat opens, so you can register before the rest of the waitlist even notices. It is free, and it is the difference between graduating on time and pushing a class to next semester.
Required class already full?
PickMyClass emails you the moment a seat opens, so you register before everyone else. Free for every Sun Devil.
Start Tracking FreeFrequently Asked Questions
When can I register for classes at ASU?
You register during your assigned enrollment appointment, a specific date and time shown in MyASU. Appointments are staggered, usually giving priority to students with more earned credit hours. You cannot register before your window opens.
Where do I actually register for ASU classes?
Inside MyASU, under My Classes. ASU Class Search lets you browse and plan without logging in, but adding a class to your schedule happens in MyASU once your appointment starts.
Why can I not register even though my appointment started?
A hold is the usual cause. Advising, financial, immunization, and other holds block registration until you resolve them. Check the Holds section of MyASU and clear everything before your window opens.
How do I add a class by section number?
Copy the 5-digit class number from ASU Class Search, then enter it in the add-class field in MyASU. This is faster and more accurate than searching for the class again inside MyASU.
What does a closed or full class mean during registration?
It means every seat in that section is taken. You cannot add it until a seat opens or, for the few classes that offer it, until you move up a waitlist. Tracking the section lets you jump on an opening fast.
Can I change my schedule after I register?
Yes. During the add/drop period at the start of the term you can swap, add, and drop classes. This is also when the most seats open up as other students adjust their schedules.
