What are the hours and when should I call?

OnStar operates the call center for this 888-466-7827 phone number 24 hours, 7 days. The short answer is that you should call on a Thursday. This observation and the following section are based on analysis of a sample set of 172 calls made in the last 90 days using our free, web-based phone (see above).
An important note: busy times vs hold times vs best time to call
When we refer to busy or less busy times, we are talking about the volume of calls. The busiest times are when the most people are calling this OnStar phone number (least busy times have fewer people calling). This high call volume does not necessarily mean that you will have a long hold time when you call. Companies like OnStar staff their call centers differently based on the time of day and day of the week, so you may experience a shorter wait on hold at the busiest of times. When we refer to the best time to call, we are referring to the optimal combination of lower call volume and shorter wait times.

The least busy time to call

The least busy day to call OnStar is Thursday. The most busy day to call is Friday, which averages 171% more phone calls by comparison. Again, this is based on a sample of 172 calls made with our AI-powered, web-based phone in the last 90 days.

The shortest wait on hold

We measured the shortest hold times to be on Tuesday. The longest wait in the queue on average occurs on Thursday.

The best time to call OnStar

In summation, the best day to call OnStar is Thursday. This is not the day with the shortest wait on hold in the phone system, but we still recommend it for its ideal combination of low call volume and short hold times. Plus we believe that OnStar staffs the call center well on Thursday.

Calling this OnStar Customer Number

I have a car that is equipped with OnStar, but the service is not currently active. I bought it pre-certified, and the previous owner must have deactivated the service. The dealer couldn't tell me much about it other than that it wasn't active at the moment. The car is for my teenager, so I like the idea of having OnStar activated again. For this reason, I called their service number to figure out the process to make this happen. 

Given that OnStar is designed for emergencies and roadside assistance, they probably get a fair amount of phone calls daily when you think about how many drivers there are nationwide. One thing I noticed while waiting on the hold line is that they do have options to skip the automated system in the case of an emergency or if you need roadside assistance, so that is comforting. 

However, getting to the customer line to discuss a basic service need is not easy. There is no direct way to talk to someone about service plans, and they refer you online quite frequently. Clearly, I don't want to use the online service or I wouldn't be using the phone line and I find that a bit aggravating. Not to mention that since I don't have an active account, that wouldn't even be an option for me. 

When I first called, an automated voice said, "Thank you for calling OnStar. This call may be recorded for quality purposes." It then gave me a list of options: "For life-threatening emergencies, press the star button now. For emergencies, door unlocks, missing persons, roadside assistance or stolen vehicles press 1. For service plan maintenance, including purchase data plan, or to renew your service plan, billing and cancellation inquiries, press 2. For technical support, press 3. If you are calling about OnStar insurance insurances, or about your insurance policy, please call 888-495-4674."

None of these options fit what I needed, but the service plan maintenance seemed to be the best bet, so I opted for that, which gave me another set of options that didn't fit my needs either. This set of options was: "To purchase data plans, or to renew your service plan, please visit online or press 1. If you sold, traded, or no longer possess the vehicle, press 2. For billing inquiries, press 3. To cancel your service plan, press 4. To update your information, please visit the owner’s center online or press 5."

Once again, I took a guess and went with one hoping I would get to someone. It told me to please wait while I was transferred to an advisor, but then talking to someone was a weird process. I kept listening to small messages from the automated assistant with random ringing in between, and then for about 30 seconds there was dead silence. Finally, at the four-minute mark, someone named Andy answered. She was helpful and answered my question, but I have to say, I didn't know if I was in the right place for most of that phone call leading up to it.

Company Facebook help page
Some customer service teams, like that of OnStar, accept inquiries through Facebook Messenger. This is a good option if you have a Facebook account, and you may even be able to converse live with an agent this way.

OnStar Customer Help Desk / Web Support

onstar.com - Customer Service
Online customer service support
As a last, sometimes only, resort- OnStar customer service can be accessed through their website. This can entail digging through help articles before finding a form and "being allowed" to submit a problem to their team, and rarely leads to a real-time conversation, which is why GetHuman does not recommend this unless it's the only way.
