One LLC operating in multiple states — one EIN

Foreign qualification doesn't change your federal EIN. State tax IDs are separate.
citeIRS Pub 1635

One entity, one EIN

The federal rule

Your EIN identifies the entity. Operating in multiple states doesn't create new entities; it creates registrations of the same entity. You keep the same EIN.

State tax IDs

Separate from EIN

Each state where you have employees or sales-tax nexus issues its own state tax ID. These are separate from EIN and aren't issued by the IRS.

Expectation-setting
Only the IRS issues EINs. No service — formation operator, attorney, CPA, or EIN-resolution shop — issues EINs. What they sell is the labor of refiling SS-4 on your behalf, not a different outcome.
