International Transactions
Guidance for payments processed on global banks.
Transaction Limits
International payment cards may be subject to different processing requirements and restrictions than cards issued by U.S. banks. Depending on the issuing bank and the country where the card was issued, transactions may be affected by purchase limits, restrictions on international or online purchases, card classification differences, currency conversion, or additional authorization requirements. Issuing banks may decline transactions based on their internal security controls, available funds or credit, geographic restrictions, or the type of transaction being attempted. These differences do not necessarily indicate a problem with the merchant’s account or payment processing system. Understanding the requirements of international card issuers can help merchants identify potential limitations, set appropriate expectations, and determine when additional information or assistance may be needed to resolve a transaction issue.
Address Verification
Address verification presents unique challenges when processing international transactions, particularly for U.S.-based businesses that ship products to customers outside the United States. Unlike domestic transactions, where Address Verification Service (AVS) is widely supported by U.S. issuing banks, many international banks do not support AVS or provide the same level of address verification functionality. As a result, the verification tools commonly used to validate billing addresses for U.S. cardholders may not be available for international transactions. This limitation can result in an unavailable or unsuccessful AVS response, even when the cardholder has provided accurate billing information and the payment card is valid. Depending on the merchant’s payment gateway configuration, fraud prevention settings, and risk management policies, these responses may trigger additional scrutiny or cause an otherwise legitimate transaction to be declined. It is important to recognize that an unsuccessful or unavailable AVS response on an international transaction does not necessarily indicate fraud or an invalid payment card. For businesses selling and shipping products internationally, or charging local customers whose cards are issued by international banks, understanding these limitations and appropriately configuring fraud prevention tools is essential to minimizing unnecessary declines, improving authorization success rates, and maintaining a positive customer experience.
Potential Risks
Processing international transactions inherently presents a higher level of risk and complexity compared to domestic transactions. Merchants accepting payments from international cardholders should recognize that these transactions may be subject to additional scrutiny, increased fraud exposure, and circumstances that require further investigation or assistance from Velocity Processing. One important consideration is how international transaction declines are communicated and interpreted. All payment transactions are processed electronically through the card brand networks, with authorization decisions made in real time by the cardholder’s issuing bank. When an international transaction is declined, the information subsequently provided by the cardholder or their issuing bank may not accurately reflect the electronic authorization response received through the payment network. For example, a cardholder may contact their issuing bank and subsequently advise the merchant that the transaction was approved, that sufficient funds are available, or that no restrictions exist on their account. However, these statements do not supersede the actual electronic authorization response. The electronic response transmitted through the card brand network remains the authoritative record of whether a transaction was approved or declined. Additionally, letters, emails, or verbal statements from international issuing banks, including information relayed by cardholders, should not be considered substitutes for an electronic authorization approval.
Our experienced team can review the transaction details, evaluate the electronic response, and provide individualized guidance to help determine the most appropriate and efficient course of action. Our objective is to help merchants navigate the additional complexities associated with international payment processing while minimizing unnecessary declines, reducing financial exposure, and maintaining a secure and efficient payment experience for their customers.
