My Montana HELP BCBS card has no group number, so I cannot create a member account. Can I create an account without one, or where can I locate it?

Through the Montana Medicaid HELP program, I received a BCBS insurance card with a member number, but there is no group number. Without that, I am unable to create a BCBS account and access the tools and information I need about my healthcare coverage. What is my group number, or how do I create an account without one?
