Online Credit Card Payment Process

You may use your credit card (MasterCard or VISA) to pay your AOS annual dues online via the AOS website with our secure online electronic merchant, There have been many safety features added by banks to prevent misuse of credit cards, this is for your safety.  As a result, you need to be very precise about the cardholder information.  You must include your name as it appears on the credit card and address as it appears on the statement. If the card is issued in a different name/institution, please be sure to enter your member name in the “shipping” field for proper credit. (I cannot change the template to say member name).

Please make sure to include your email address during the process, this will ensure that you are e-mailed a receipt of payment.  If you have difficulties with the process or are unsure if the transaction was processed, please contact the AOS Administrator, Kristen Bordignon by phone at 217-638-0801 or email at and I will confirm the transaction or assist you with the process.

*Please note if you’re located outside of the U.S., you may use MasterCard or VISA. If you prefer to mail your payment, please note international checks must be in US Dollars with an ABA nine digit routing code and drawn on a USA commercial bank made payable to the American Otological Society.  We do not accept foreign money orders.
