AVS - Address Verification Service - is an additional security precautionary tool.
Cards issued within the UK support AVS/CVV checks. Conducted by the issuing bank, AVS checks that information provided by the cardholder matches the registered address and zipcode on their banking records. It is considered an added security measure and can prevent fraudulent activity on your account.
AVS performs two checks on the customers address:
- It assesses whether the numerical values provided in the
billing_streetparameter matches with the numerical values of the cardholder’s street address as recorded on the issuing bank's system.
- It verifies that the numerical values provided in the
billing_zipcodeparameters match the numeric values of the cardholders zip code, as recorded on the issuing bank's system.
After the issuer completes the check, Acquired.com receives Matched, Not Matched, Not Checked or Not Provided within the response.
