I booked the Poly a couple months back and POFQ yesterday with AAA rates. I did not have to have my number. As a matter of fact, I didn't join AAA until the day after I booked the Poly reservation with the AAA rate. I called back to give them my number and the CM said he didn't need it, just present my card at check-in. They will ask for your number, but will book the discount even if you don't have it to give them.
