AT least for Binance, I have located their address on the google map. The way they put their address on bbb.org apparently is tricky and evasive manner, in such a way that just typing to google map finder does not immediately show up. You have put some effort into it:
BBB web site address
ONE LETTERMAN DRIVE, BUILDING C, SUITE C3-800, THE PRESIDIO OF SAN FRANCISCO, SAN FRANCISCO, CA, 94129, UNITED STATES
does not work very well.
After some tinlking around I found what appears to be an exact match, there is something called BAM trading service situated in one of the building in Presidio drive. If anyone in the US, especially in the bay area or other area, being oppresssed by binance's elusive policy should reach out or at least try to reach out by coming in person there:
Google map findable address:
Building C, 1 Letterman Dr C3, San Francisco, CA 94129
