Your EUC ??
You could also make a nice, slightly enlarged, color copy at Kinkos or Office Depot.
I would also include a color copy of a passport or any other federal ID like a pilot's license, mechanic's license, Military ID, etc. as this just doubles their warm and fuzzy that you are who you are.
The billing address for the phone is important too and the billing address and your ID adresses should all match. If they don't you don't automatically flunk out but you have a much better chance of not passing on the first go around.
I would send it all in in the US Mail with a certified sticker on it so they can not deny that thney received it but that is up to you.
I hope everything works out quickly for you.
You generally start runnig a fever about 10 hours after your first purchase notification and it slowly progresses into a life-long Green Disease that is incurable.
I and many others have been afflicted with this and will never be able to be cured.
