I've had mine in there since day 1 of my target fun (haha). Now that target circle is rolling out, the people who didn't add it to their phone or website are now wanting to know how. I can see my # under account/settings on the target.com website using an actual computer. I'm assuming it can be added there by new TMs. Can it be done on a mobile device? I can see it in my cartwheel app, too....
