Recently, I have had 4 orders, all marked "High risk of fraud detected." It's possible, but I'm mixed on this.
Red, I figure, is high fraud. I think the gray items weren't a problem, and items light blue are ok?
"Contact the customer to verify their identity and the purchase before you fulfill the order." <- How do I do that?
There is a lot of fraudulent activity this year compared to last, due to more people doing their shopping online. You can either email the customer or reach out by phone. The phone option is best because you can actually speak to confirm the identity of the person in real-time and to see if the phone number provided is real or not. Otherwise, you can contact them by email and ask to make sure they have made the order they intended.
Just a quick FYI, Shopify's fraud analysis isn't always accurate and it's known to miss classify good and bad orders. Treat it as a warning and for those orders that have a medium to high risk, make sure the actual person has intended to buy what they wanted and that they know what the return policy is. It's really up to you as a merchant to decide whether or not you want to go ahead and process the order.
In case of a possible chargeback, contact your payment gateway provider and ask them what you should do and what evidence can you submit in order to help your case. If you want to know what else to look out for, I recommend you read the following article for more resources on what to look out for to determine a bad order.
I hope this helps you.
Unfortunately just judging an order's legitimacy based on metadata like IP address, billing address vs shipping address & device details aren't enough to know if a card card is stolen.
Masking your IP address and finding the personal details of stolen credit card holders is much easier for criminals than it ever was before.
To make matters worse, the line of signs of fraudulent activity vs legitimate online orders is more blurred than it ever has been. Customers are buyings gifts for friends and family in far off locations, mismatching billing & shipping addresses are the new norm.
These fraud signals are now noise.
You can use an ID check to 100% verify the riskiest of your orders. That way you're not stuck guessing if an order will lead to a chargeback or not. You can verify the details of the customer's government issued ID with their billing information.
