In the financial world, your passport at most counts as a "face," but your address is your "bill of sale."

Why is an address more important than identity?

Taxation is all about territory: most government offices worldwide don't care which country you're from; they only look at whose land you're on. Whoever's land you live on, you have to follow their rules and pay accordingly—that's an iron law.

Fake information is just "double-dealing": you hold a Chinese passport but insist on using an overseas address. The brokerage system gets confused: who exactly are you under? Since it's unclear, it defaults to treating you as a problematic "undocumented" person.

Direct penalties: once your address is verified as fake, Americans don't care who you are—they'll trigger the harshest 24% backup withholding tax. Note, it's 24% on the sale amount, even including the principal, with no room for argument.

So, where your body is located, that's where you should fill in your address. Don't try to be clever just to open an account, or you'll end up giving your principal as a tip to the IRS.
