What is Address Verification Service or AVS?
QuickBooks POS performs an Address Verification Service (AVS) check on all credit card transactions that are entered manually. The service checks if the customer’s Zip Code matches the address currently on file at the cardholder’s bank and alerts you if there is a mismatch. The results of this check are strictly for your information; the transaction can still be authorized. If you suspect credit card fraud, you should consider canceling the transaction. (See the preference note below to specify how you want to handle this situation.) • Preferences: Address Verification Service (AVS) PREFERENCES –> COMPANY –> CARD SERVICES –> Address Verification Service (AVS) mismatch options: Specify how you want to handle AVS mismatches: • Ignore mismatch and complete transaction (lowest level of fraud protection), • Alert me, but allow transaction, or • Do not allow transaction (highest level of fraud protection).
