The Merchant Account Show should help you with your merchant account and electronic payment gateways. Also
hopefully it will help explain some fraud attempts and how to notice fraud
on your orders. Remember, the net powers us!
This podcast is brought to you by LoudCommerce.com, and voiced by Lynn
Lynn Brooks.com. Today, let’s talk a little bit about “Merchant Direct Access Service”.
Visa offers merchants a service called the Merchant Direct Access Service (MDAS) which allows merchants access to address verification service (AVS) via a toll-free number, using a touch-tone phone. The service is specifically targeted to small mail order / telephone order (MO/TO) or Internet merchants for whom AVS may not be cost-effective. Merchants using MDAS are charged on a “per transaction” basis.
To use the MDAS, you need access to a touch-tone telephone and your Merchant Access Code (MAC) which you can obtain from your merchant account provider. To request an address verification, call the MDAS toll-free number, 1-800-VISA-AVS (1-800-847-2287). An automated voice unit guides you through the process of submitting a customer’s account number and address, and gives you the results of the verification.
MDAS responses are similar to AVS, but do not include a single-letter response code. There are currently five responses that can be obtained from the MDAS:
Exact Match: Street address and zip code match
Partial Match: Street address matches, but not zip code or zip code matches, but not street address
No Match: Neither the street address nor zip code matches
Retry Later: Card issuer system is not available at the present time
