Someone called me to ask me for my merchant ID number -- said they wanted to make sure that my account is able to accept Discover credit cards. She wanted me to run a number as a "test". I told her I didn't understand the purpose of her call and she eventually hung up. NEVER GIVE OUT CONFIDENTIAL INFORMATION TO RANDOM CALLERS!

No, it's a scam. They called me with the same request. Said they were from Discover and noticed my business wasn't getting any transactions for their card and wanted to verify it was working properly. Was going to give me a card number to run. I didn't do it but I called Discover's fraud activity number and asked if this was something they did. I was told it was not.  They're apparently giving you someone's number and want you to validate it.

Actually this is not a scam, if you would have taken the call or called them back you would have seen that they were simply trying to verify if you as a merchant accept Discover from your customers. I did a test for my salon and was able to get free decals pens etc from their website, things that other companies were charging me for.

Says they are from Discover Network. Asking me to run a credit card for them? Sounds like a scam
