IIAS Merchant List

This is a list of merchants who implemented or intend to implement the SIGIS IIAS standard. The planned merchant implementation dates shown have been provided by the merchants and may be subject to change. When using your debit card at a merchant with IIAS, you will not be asked for additional substantiation as this is done at the point of service by the merchant. If you do not find your favorite merchant listed here, check with your merchant to see if they implemented a proprietary (non-SIGIS) IIAS or plan to implement IIAS in the future. This list does not include merchants adopting an IIAS solution other than the SIGIS Standard. SIGIS certification is not a requirement of the IRS and some merchants, such as Walgreens, have implemented their own proprietary IIAS. Walgreens' IIAS is fully compliant with the IRS requirements.

Form Type: Reimbursement and Substantiation
