EINs are drawn from the Form 5500 the employer filed with the U.S. Department of Labor. An employer’s EIN is the same across all of its plans — open a filing to confirm the sponsor name and address before relying on it.

How to find an employer’s EIN in Wyoming

Every employer that sponsors a retirement or health plan files a Form 5500 that lists its nine-digit Employer Identification Number. Find a Wyoming company in the table above, or run a Form 5500 search by company name to pull the filing and read the EIN directly from it.

For a broader view of plans in the state — including industry breakdowns and the largest plans by assets — see Form 5500 plans in Wyoming. New to these filings? Start with What is Form 5500?
