Payment FAQ

Below are the most common payment issues and tips on resolving them.

Declined Credit Card Transactions

  • Your member profile address does not match that of the billing address for the credit card. Check that your ICRS address matches your credit card's billing address.
  • Your university or organization credit card requires pre-approval or has a specific list of approved business types for purchases. Check with your organization.

Total Amount is Incorrect

  • Make sure there are no spaces in blank fields which can change the amount owed.
  • The Member Type and Membership Options drop down fields on the membership form must match. If they don't, your membership fee and/or expiration date will be incorrect.

VAT Identification Number

  • ICRS is incorporated in the United States and therefore does not collect VAT.
