What do you mean?
AFAIK, you can get utility bills delivered to your address. You can also get confirmation with you name and address from Georgian banks.
In my personal experience, you really can't.
Not only that, but even online bills don't look like what you'd expect to see in most places in the world.
The only bill I've ever seen with an actual name and address on it is the electricity bill, but even that's just a tiny slip, which I very highly doubt would do any good at all in a KYC situation. And if you rent, then even getting that slip would be a challenge, as the main utilities (water, electricity, gas) always remain on the property owner's name. To my knowledge, this isn't by choice but by regulation. So you're stuck with Internet, but I don't believe any of the larger providers provide an actual bill.
Most people seem to take one of two routes - either a bank letter / statement (BoG is a bit better in this regard than TBC), but that's no good in many situations as a lot of banks know full well how easy it is to get any address to appear on a bank statement, and therefore don't consider these sufficient. Or a letter from the embassy of the person's country of origin, but needless to say, that takes a lot of time and paperwork, and may not be possible at all, depending on the country in question.
From my experience having lived in Tbilisi for over half a year, the only document I have ever received in post with my name and address on was a letter from the tax authorities of the country that I resided in previously. And that's it. In 6+ months.
