UPDATE: I would like to add that while booking an appointment (the process that need location code) per experience is not really neccesarry as long as you have your printed email confirmation, I am not sure yet if this process can be done in provinces or any other center which are not mentioned on their list of booking code HERE:
TIP: (From one of the readers)
Confused? got some questions or think that I forgot a step? Drop a comment and I will get back to you the soonest as I can.
