The membership office is closed to walk-in visitors during the off-season, but you can purchase or renew your membership online anytime. We will still return all phone calls and emails, though responses may take a little longer than usual. Thank you for your patience.
Your membership welcome packet, including your membership cards, will be mailed within 3 business days during the regular season and within 5 business days during the off-season. If you plan to visit the zoo before your cards arrive, show your membership receipt & photo ID at the front gate for entry.
Purchased a Premium Membership online? Your ride tickets will be mailed with your membership cards and will not be available for pickup at the zoo.
Lost, damaged, or undelivered cards
If your welcome packet has not arrived within 10 business days of purchase, or if your cards are lost or damaged, contact our membership department at 309-799-3482, ext. 237, or membership@niabizoo.com. We will issue replacement cards for a $5.00 replacement fee per card. Until your replacement arrives, present a photo ID at the front gate, and our staff can look up your membership.
