If I remember correctly, press 2 for PSP, then 0 for the operator. Took 3 weeks and 2 phone calls for me to get my codes. The tech department claimed my codes were sent out 2 days after I registered my Go (which was a Sunday), but CS reps (the ones who answer your call first) said they're only sent every Wednesday. Dunno which one was lying, but it was a hassle. Some people get them, some don't - it's all random... Good luck!
