If you receive a “billing address does not match” error while adding a credit card in the Kasa app, it means that the information you entered may not be verifying correctly with your credit card’s issuing bank.
TP-Link do not store the billing address information, all the payments will go through the payment gateway, processed by the card-issuing bank
If your payment card is declined by the payment gateway, please kindly check the following tips.
- Ensure that there are no missing characters or misspellings in the name and address you entered and that the card number you entered is correct.
- Double-check the zip code and ensure it matches the one it has on file. Please contact your bank to check what the card-issuing bank has on file if necessary.
- Try to use another credit card if available.
