Looking for Your Member ID Number?
Depending on your plan, you may find your member ID number in a few different places.
Express Scripts Member ID Card: Your card may look different than the example shown.
Medical or Health Plan Card: If you don’t have an Express Scripts member ID card, enter the number on the card you usually present at the pharmacy. This may be your medical or health plan ID card.
Social Security Number: If you don’t have a prescription or medical ID card, enter your Social Security number.
If you can’t find an ID number associated with your prescription drug plan, please contact your plan sponsor for help.
