Why is my phone number not showing up in my ad?

Hi there, Unfortunately, it is our policy that every first interaction between buyer and seller through CarGurus is over the email accounts registered on the site. This is to protect user's personal information as well as allow us to track the interactions between users and maximize our user experience. Because of this, we do not allow phone numbers to be listed on our site. I am sorry for any inconvenience this may have caused. Please let us know if you have any more questions!
