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 Delaware
Every employer that sponsors a retirement or health plan files a Form 5500 that lists its nine-digit Employer Identification Number. Find a Delaware 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.
