The credit bureaus were unwilling to validate requests from non-US address when I tried, just after news broke of the Equifax breach. The online forms literally had no provision for changing the country, with US State and ZIP code (of my current address) being mandatory fields.

I asked about it in the expats Stack Exchange site and others had the same problem: https://expatriates.stackexchange.com/questions/12104/how-ca...

Same goes for Social Security accounts, they require a US address before they permit you to log in online and monitor your account for fraud.
