Does Coinbase share data?

I get so many phishing texts about log in confirmations and to call x number if it wasn't me basically since I opened an account. Was there a leak or something that allow these phishers to get access to my phone number being associated with an account? Seriously considering pulling out of coin base due to being fed up with the constant texts being so annoying. I have my account locked where you need to provide a selfie with ID to get into it so I know they are fake but it's obnoxious. Is this a common issue with Coinbase?
