When it comes to verifying my employment history a company can only verify one and they use The Work Number for that but I am unsure if the new company would have records for the old employees under the former company.
What to do? I really need to improve my resume so I can get a job.
Remember that what goes on your resume is not the same as what goes on an application. The company status isn't relevant. If a company is still in business, and you think it'll be relevant to the prospective employer, you can add a "(now ABCo)" -- but only if you think it really adds value.
A resume is a summary, and a teaser summary at that. It should not answer every possible question a prospective employer might have. Instead it should make them be interested in learning more. All of those experiences could be relevant -- depending on the opportunity you're aiming for.
