Question: Can an employer change the employer's Employer Identification Number (EIN) after coverage has been effectuated? If yes, will issuers receive a Group Extensible Markup Language (XML) maintenance transaction for this scenario?

Answer: No, employers cannot change their EIN once coverage has been effectuated. Employers could, however, terminate coverage for the entire group and reapply for coverage with the new EIN.
