AVS(Address Verification Service)- If the customer billing address during checkout does not match the address on file with the card-issuing bank or credit card company, this causes an AVS mismatch error. An address verification service (AVS) is used to protect customer and merchants from credit card fraud. Customers can avoid AVS mismatch errors by ensuring that addresses provided at checkout match the addresses printed on their credit card statement. Resolving AVS mismatch errors often require consumers to contact their bank or card issuer. These errors can be a hassle, as they often result in the bank putting a hold on the funds for 2-3 business days while the discrepancy is sorted out.
