A business, especially one which is online, may at times need to collect information from its customers. These are usually the name and contact information of the customers, particularly those that are paying through a credit card.
This means that the business should have a system or systems that they employ in order to confirm that the information given is clean, correct and legit. This is usually done through the use of email address validation and address verification services.
This is to steer clear of users entering email address that are formatted the wrong way, as well as ensuring the legitimacy of the addresses since they can accidentally give us a wrong address or email address.
An email address verification function checks that the address wasn't put in with multiple @ signs or commas instead of periods. You can do so by using a pre-programmed software that you can purchase, or if you are a real techie, then you can create your own syntax and protocol to do so.
On the other hand, address verification services is a procedure which is used to confirm the identity of the person claiming to own the credit card used to make a purchase. This method will verify the billing address of the credit card that was provided by the client with the address on file at the credit card company to which the card belongs.
The AVS uses its electronic database system to check the card holder's address, specifically the numeric portions of such. For example, if the cardholder's address is 42 Maple Drive, Nowhere, 96511, then the AVS will check the street number 42. It will also check the postcode of the state, which in this case is 96511. However, if an apartment number or any additional numeric address is given, The AVS will check on that as well.
Making use of email address validation and address verification services has its advantages. For one thing, the receiver of the payment is ensured of the legitimacy of the transaction. The card holder can also be assured of prompt delivery since the correct address is given.
Once in a while, the card holder might experience having his transaction denied. This could be due to a number of things such as bad credit or wrong information. The retailer will then have to do a manual override or call the card company, depending on the situation at hand.
