COSI is now open!

What is COSI’s reciprocal admission policy?

COSI’s policy allows free admission for 2 adults and up to 4 children listed on the reciprocal membership.

Please note, COSI cannot verify memberships from reciprocal museums. Reciprocal visitors must present current membership cards and photo ID when checking in at COSI’s Box Office (General Admission line).

COSI also checks IDs for the sake of the ASTC residency rule. Benefits do not apply to reciprocal visitors who live within 90 miles of COSI.

Please note that ASTC free reciprocal admission to COSI does not include the American Museum of Natural History Dinosaur and Special Exhibition Gallery, COSI Planetarium, COSI Giant Screen Theater or the COSI Motion Simulator. Tickets for these experiences may be purchased at COSI's Box Office.
