Parent Company has same EIN as subsidiary

[IhrtERISA]

A parent company was formed after a company merger (Parent, Company A and Company B). Both companies in the merger have their own 401(k) Plan. Intent is to rename the plan sponsor of Company A Plan as Parent Plan and make Company B a Participating EMployer.

Issue is that the EIN assigned to the Parent is the same EIN as Company B.

The goal is for their to be no new participants in Company B Plan (but not to freeze it), with all new participants going into Parent Plan.

Any thoughts?

Thanks.

Isn't that the point of different plan #'s?
