I'm trying to open a bank account in BA. I've been instructed that I need to get a CD to prove residence, which I did, and now I need to get a tax ID number (CID). However, I can't seem to find out where the closest office to do this is. It seems the website is either down, or it can't recognize my address. I'm in Villa Crespo, near Palermo. Does anyone have experience with an office around here (Thames y Cordoba)? Or will I have to go downtown?
