The first time I tried to exchange dollars for euros at a Parisian bank, I was convinced all I’d need was a smile and my stack of twenties. Wrong. The teller eyed me suspiciously, asked for my passport, and then—despite my best attempts at French—told me I needed proof of address, too. That’s when I realized: changing money isn’t as universal as it seems. Regulations differ, and sometimes the rules change overnight (especially after events like the 9/11 attacks or new anti-money laundering laws).
Before we get lost in bureaucracy, let’s break down the steps and requirements you’ll likely face, using actual experiences and real screenshots from major banks and exchange offices.
The requirements vary a ton depending on the setting. For example, banks are stricter than small currency kiosks, and airports can be surprisingly relaxed (but expensive). I once exchanged $500 at a Charles de Gaulle airport kiosk and was only asked for my driver’s license—no passport, no paperwork. But at a Crédit Agricole branch in central Paris, I was required to show my passport and fill out a transaction form.
Screenshot Example: Here’s a snippet from Deutsche Bank’s website (in German, but Google Translate helps):
"Für den Umtausch von Bargeld in Fremdwährungen ist ein gültiger Lichtbildausweis erforderlich." (“A valid photo ID is required for exchanging cash into foreign currencies.”)
For small amounts (under 1,000 euros), most exchange offices will simply log your name and check your ID. Over 1,000 euros, you’ll often be asked to fill out a declaration form—as per EU anti-money laundering directives (Directive (EU) 2015/849).
Real-Life Anecdote: A friend tried changing $2,000 at a London post office. She was told she needed both her passport and proof of where the money came from (a payslip or bank statement), since the transaction exceeded the reporting threshold.
Sometimes yes, but don’t count on it. Many French, German, and Italian banks only accept passports as ID for non-residents. In Spain, I got lucky at a CaixaBank branch because the teller had lived in Chicago and was “feeling generous”—but that’s hardly a strategy.
Imagine you’re in Berlin with $800 in cash:
Now, in Barcelona:
The short answer: anti-money laundering (AML) laws. The EU and US both require banks and exchange offices to verify the identity of anyone exchanging large amounts of currency. According to the US FinCEN, any transaction over $10,000 must be reported, and the EU sets its threshold at €10,000, though many banks start paperwork at much lower amounts.
According to the OECD, “financial institutions are required to undertake customer due diligence measures when carrying out occasional transactions above the designated threshold.” That’s why you might get grilled for ID or source-of-funds even for what feels like a modest sum.
Country/Region | Threshold | Key Law | Enforcement Agency | Notes |
---|---|---|---|---|
United States | $10,000 | Bank Secrecy Act | FinCEN (Treasury) | Currency Transaction Report (CTR) required above threshold |
European Union | €10,000 | Directive (EU) 2015/849 | National FIUs | Banks often require ID at much lower amounts |
United Kingdom | £10,000 | Money Laundering Regulations 2017 | HMRC | Proof of funds may be requested |
Japan | ¥1,000,000 | Act on Prevention of Transfer of Criminal Proceeds | National Police Agency | ID required for all foreign currency exchanges |
Here’s the annoying part: even if you just want to exchange $100, some places won’t budge without ID. Once in Rome, I tried to swap $200 at a Travelex branch. No passport, no deal—even though I had my US driver’s license. The teller pointed to a sign: “Only Passports Accepted.” Lesson learned: snap a photo of your passport and keep the original handy, just in case.
Another curveball: your name on the document must match the name you give, or you risk the teller refusing the exchange. I’ve seen it happen to a friend whose married name was on her bank card but her maiden name was on her passport. Awkward explanations followed.
After plenty of trial and error (and some embarrassing mix-ups), here’s my advice:
For the regulatory-minded, you can always consult the WTO’s financial services rules for an overview of cross-border financial compliance, though practical details are usually buried in the fine print.
In the end, the best strategy is to over-prepare: bring more documents than you think you’ll need, and remember that every teller, bank, and country can interpret the rules differently. If you mess up or get turned away, don’t take it personally—it happens to all of us. Next time, you’ll be ready.
