So Santa bought be a new phone for Xmas and I want to get it registered online so I can manage my account/top-ups over t'internet 
The site asks me to enter the phone number (which I've done) and it then asks me for a 4-digit identity code, which I don't know.
The phone was bought as a gift from me from an Orange shop and I have the box it came in here and I can't see anything that would hint at what the code is.
I also only found the number of the phone by ringing my landline and using 1471...
Anyone got any idea where I can find this 4 digit number?
