Museums and Cultural Institutions
The 2018 Museum and Cultural Institution Benefits
IDNYC cardholders are now eligible for free one-year memberships at over 40 participating institutions in 2018.
Your IDNYC card must be valid. It DOES NOT matter when you received your card.
You can join any institution where you have not been a member since January 1, 2014. If you were a member after that date, you cannot get a free IDNYC membership at that institution. You are still eligible for the other memberships.
Please note, not all 2017 institutions will be returning as IDNYC benefit partners in 2018.
If you received your card in 2017 and you want to join an institution that will not participate in 2018, you must join no later than December 31, 2017.
