What is Moto G 8GB Black Global GSM model number?

[Booz Sarmiento]

I have seen best buy is now offering Motorola - Moto G 2nd Generation Cell Phone (Unlocked) - Black, which has a model number of 00503NARTL? My question is, is this a global gsm variant or a us gsm?

just bought one yesterday and works fine on AT&T. I searched for it and it has at&t and t mobile bands.
