How do I resolve AVS Zip Length Error?

Overview

During the check out process in my Ecommerce shopping cart, an error message is received: "AVS Zip Length Error (error code 106)."

Environment

Magento 1

Resolution

  • This isn't an AvaTax error response, it's a result of the payment processor not accepting the 9 digit zip code after address validation
  • To resolve this issue, review the payment processing application settings.
    • Determine which settings need to be adjusted in order to allow 9 digit postal codes to process
      • Contact the Payment Processing application's Technical Support line for assistance, if necessary
  • If there is no way to adjust the allowed postal code length in the payment processor, you may adjust the AvaTax for Magento 1  settings to turn off address validation.
