Can I use my membership without my membership cards?

Yes, a Box Office associate can verify your COSI membership information in a computer database provided you present a valid photo ID at the time of check-in. Children must provide the adult names and address listed on their membership in order to check in using the computer database verification.

Please note, COSI cannot verify memberships from reciprocal museums. Reciprocal visitors must present current membership cards when checking in.
