Or, they publish it to selected clients..... I just got my new Equinox, and on day 2, I got a call in the car from a business that has been harassing me for several years on my home phone. I have already talked to an attorney about this firm and now they have my ON STAR number !!!
I had problems with my Terrain early on getting phone calls from odd callers and businesses - I think they recycled the phone number too soon from a previous number holder. I don't know if the number are specific to OnStar but Verizon is the service provider so in my case it could have been a Verizon customer that had the number before and not an OnStar customer.
In your case it may not have been shared/sold by OnStar? - it could have been your dealer?? They also have access to your new OnStar phone number.
Not sure why they would have shared it as their privacy policy does not share your information with third party companies.
Here is part of the OnStar privacy statement (from their website)
# We may share information we collect from you with your car's maker, your dealer, your satellite radio or wireless service provider, your fleet company, or your rental car company, if applicable, when required by law, or in the event of the sale or transfer of OnStar business.
# In general, we do not share your personal information with third-party marketers, unless we have asked for and obtained your explicit consent
