“using my family’s U.S. address as my mailing address”

For a U.S. citizen living abroad who uses a U.S. address for bank and brokerage accounts, there are several legal, regulatory, and practical considerations tied to “Know Your Customer” (KYC) rules, tax obligations, and financial institution policies. Below, I’ll break this down step-by-step, focusing on how KYC applies, potential issues, and what you should be aware of.

KYC Implications

Under KYC regulations (e.g., the Bank Secrecy Act, USA Patriot Act, and FINRA rules), banks and brokerages must verify a customer’s identity, assess their risk profile, and monitor their accounts. Using a U.S. address while living abroad introduces complexities:

a high-risk country (per FATF or OFAC lists)
Financial Action Task Force (FATF) - an intergovernmental organization to combat money laundering and terror financing. hosted by the OECD in Paris, but separate.
Office of Foreign Assets Control (OFAC) - US Dept of Treasury, enforces economic and trade sanctions against targeted foreign countries and others.
Organization for Economic Cooperation and Development (OECD) - 38 member countries, to promote democracy and the market economy

Note: both passport and SSA ask “Is this your residence?”

Potential Issues

How to Navigate This

Bottom Line
A U.S. citizen living abroad can use a U.S. address for bank and brokerage accounts, but it’s a gray area that depends on institutional policies and your transparency. KYC rules don’t explicitly forbid it, but they do require accurate risk assessment, which might expose your foreign residency over time. To avoid issues, select expat-friendly providers, maintain a valid U.S. mailing address, and fulfill all tax and reporting obligations. If you’ve got a specific bank or brokerage in mind, I can dig deeper into their policies—just let me know!
