Yes, you can trust Webull with your Social Security number. Webull uses top-of-the-line encryption to protect your data. In addition, the company’s privacy policy states that it shares personal information, like Social Security numbers, only with third-party analytics companies such as Google Analytics. Webull does note that if it is purchased by another company, that company will then own its data assets, including customer information. In addition, the policy reminds users that no company is entirely immune to data breaches. Taking these factors into account, however, we can say that Webull will protect your Social Security number as well as any investment company out there.
