Membership Year

SIOP’s membership year runs from Jan 1 to Dec 31 of each year. SIOP’s membership year is not based on 12 consecutive months from the date of purchase. For this reason, SIOP strongly encourages you to renew your SIOP membership early into the calendar year.

Automatic Renewals

When you join SIOP and pay your membership by a credit card, the auto-renew of your membership is the default setting. As such, SIOP will renew your SIOP membership so that you have no gaps in your SIOP membership. On the last day of the membership year (Dec 31), SIOP will charge the credit card on file – this is the credit card last used to pay for your SIOP membership. If you do not wish to automatically renew your membership, please follow these steps to change your preference. SIOP will remind you approximately 2 weeks before the automatic renewal charges your credit card.

Multi-year Discount

When you join SIOP, you will be asked to choose between the 1-year or 2-year memberships. Use promo code SAVE5NOW to receive 5% discount when purchasing 2-year memberships. If you wish to purchase a SIOP membership for 3 or more years, please contact membership@siop-online.org for instructions.
