Added ZIP/postal code verification (AVS) to Direct Payments

July 17th, 2026

Direct Payments now accepts a cardholder ZIP field for address verification (AVS) on Sale, Auth, and Pre-Authorization transactions. The field accepts a US ZIP or ZIP+4, or a Canadian postal code.

When ZIP verification is enabled on a terminal, ZIP becomes required on those transaction types. Two response codes cover the new validation:

  • 1042 INVALID ZIP — the supplied value isn't a valid US ZIP/ZIP+4 or Canadian postal code
  • 1041 MISSING ZIP — ZIP verification is enabled but no ZIP was supplied

See Parameter Descriptions and Error Codes for details.
