Jack Daniels says:
Numbered bank accounts and even lines of credit exist and will continue to prosper.
One can hope so, but when the Swiss numbered bank account, the canonical example, vanishes, I begin to have doubts.
[Let's hope it doesn't get this far. Besides, there's always Liechtenstein :)]
I hate to be the bringer of bad news, but to the best of my knowledge Switzerland no longer allows numbered bank accounts. Also, from my studies of international banking, bank secrecy and tax havens, I have never seen any reference to numbered bank accounts in any country other than Switzerland, including Liechtenstein (although Liechtenstein does have better secrecy safeguards than Switzerland.
"Jack Daniels" has never looked hard enough -- many countries (Austria comes to mind) allow completely anonymous accounts, with various degrees of restriction on them. Perry
