Frequently Asked Questions

My billing address is correct, so why can't my transaction be processed?

Because the Address Verification System is an automated system that relies on the exact match up of address data, records that are entered in different formats can sometimes interfere with credit card processing. For example, some companies do not follow a standard procedure for entering P.O. Box numbers, so online donors with P.O. addresses are more likely to experience problems. If you reverse the format of the address line (e.g., enter in the address 1234 P.O. Box rather than P.O. Box 1234), you may be able to resolve the problem. Donors with international addresses may also run into authentication issues.

If you run into difficulties with the online form, the Conservancy's Member Care Team can always process your credit card donation over the phone or by mail. Please call us toll-free at (800) 628-6860 for assistance and more information.
