Address Verification System

Make the most of this additional fraud measure when taking CNP transactions.
 

Mail and telephone order solutions: Address verification system

We strongly recommend that you use the Address Verification System (AVS) as an additional fraud measure when taking CNP transactions. AVS allows you to check the numerical portion of a cardholder's address and the card security code (also known as CVC/CVV) either on your terminal or when calling for CNP authorisation.

It is a free service and is also a quick and easy facility to use that will not slow down your terminal authorisation process and will increase your chances of avoiding fraud.

What is AVS? 

AVS (Address Verification Service) allows you to check the numerical portion of a cardholder's address and the card security code (also known as CVC/CVV) either on your terminal or when calling for CNP (Cardholder Not Present) authorisation.

Why use AVS? 

It is a quick and easy facility to use that will not slow down your terminal authorisation process and will increase your chances of avoiding fraud.

How much does AVS cost? 

AVS is a free service

Does AVS guarantee payment? 

No. Neither Streamline nor any other Acquirer offer a guarantee of payment. However, by checking additional data you are increasing your chances of avoiding fraud.

What information do I have to obtain from the cardholder? 

When you have a CNP transaction ask the customer to give you the address details as shown on their card statement and the last 3 digits on the signature strip on the back of the card.

How do I get AVS? 

Terminal users – if you rent your terminal from streamline, this facility should already be available. If you do not rent from us, you should contact your own terminal supplier

I still take paper card transactions, is AVS available to me? 

Yes. This facility is available via the CNP authorisation IVR facility (0845 600 530 option 1). Please note that should any of the authorisation information be keyed incorrectly, you will be transferred to an advisor and you will need to ask them to transfer you back into the system.

Is this service available on all debit and credit cards? 

No. The service applies to UK issued MasterCard, Maestro Domestic, Visa And Visa Debit cards only; it cannot be used to check cards issued in other countries outside the UK.

Any other Queries? 

Please refer to the Mail Order Telephone Order section of your Merchant Operating Instructions, for more information about the Address Verification Service.
