To purchase foreign currency in the United States, you order it from your bank, buy it from an online vendor for home delivery, or walk up to an exchange counter with a government-issued photo ID and cash, card, or a bank transfer. The method matters: banks and credit unions usually offer the best exchange rates, online vendors fall somewhere in the middle, and airport kiosks charge the most. Federal rules also start applying once a transaction crosses $1,000, and more rules apply at $10,000.
Ordering From Your Bank or Credit Union
If you already have a checking or savings account at a major bank, that is almost always the cheapest place to buy foreign currency. Most banks let you place the order through their mobile app or website. You pick the currency, enter a dollar amount, and choose whether to pick it up at a branch or have it shipped to you. At Bank of America, the minimum order is $100 through the app and $300 in person at a branch.1Bank of America. Placing a Foreign Currency Order FAQs
Standard delivery runs one to three business days, with overnight available for a premium. Standard shipping is around $7.50, sometimes waived on larger orders (Bank of America drops the fee on orders of $1,000 or more), and overnight runs about $20.2Bank of America. Order and Deposit Currency At the branch, bring your photo ID and the teller will confirm the order before handing over the cash.
Watch the upper limits. Online orders are often capped at $10,000 in foreign currency over a 30-day period, and anything above that typically has to be done in person.1Bank of America. Placing a Foreign Currency Order FAQs Not every bank carries every currency either. Euros, pounds, and yen are nearly always in stock. Less common currencies may take longer or may not be available at all.
Buying Online for Home Delivery
Several third-party vendors sell foreign currency online and ship it to your door. The process mirrors a bank order: pick an amount, choose delivery speed, pay by debit card or bank transfer, and verify your identity at checkout. These vendors fall under the same federal reporting and record-keeping rules as banks.
Delivery takes one to three business days, and someone has to be home to sign for the package. Home delivery through Bank of America is capped at $1,000 in foreign currency over a 30-day period, with larger amounts requiring branch pickup.3Bank of America. Receiving Your Foreign Currency Order FAQs Limits vary by provider, so check before you order.
The real cost is the exchange rate markup. Every provider builds a spread into the rate it quotes you, meaning the gap between the mid-market rate and the rate you actually pay. That spread is where most of the profit sits, and it is rarely itemized on your receipt. Before you commit, compare the quoted rate against the current mid-market rate on a financial data site. A spread of 1 to 3% is normal for banks and reputable online sellers. Wider than that and you should shop around.
Airport Kiosks and Retail Exchange Counters
Exchange desks at airports and in tourist areas are the most expensive way to buy foreign currency, and this is where first-time travelers lose the most money. Spreads are wider than at banks, and some kiosks layer a flat service fee on top. The convenience is real. You pay for it.
The transaction itself is simple: hand over your ID and your cash, and the clerk converts it at the posted rate. Review the receipt and count the notes before you walk away. Once you leave the window, disputes are nearly impossible to win.
If you can avoid the airport counter, do. Order from your bank before the trip, or use an ATM when you land. Keep the kiosk in reserve for emergencies, like a cab fare’s worth of local currency on arrival.
Using ATMs Abroad
Pulling local currency from an ATM at your destination is often the most practical approach if you did not pre-order. Insert your debit card, choose an amount in the local currency, and the machine handles conversion. Your bank’s rate is usually close to the mid-market rate, which beats most airport kiosks.
Fees are the catch. You may face up to three charges per withdrawal: a foreign transaction fee from your bank (typically 1 to 3%), an out-of-network ATM fee from your bank ($2 to $5 is standard), and a surcharge from the ATM operator. These add up fast on small withdrawals, so take out larger amounts less often.
One trap to know about: the ATM may offer to convert the withdrawal into dollars on the spot. This is Dynamic Currency Conversion, and you should decline it every time. When you accept, the ATM operator sets the exchange rate instead of your bank, and that rate almost always carries a steep markup. Choose the local currency and let your own bank do the conversion.4Visa. Dynamic Currency Conversion Explained The same goes when a merchant abroad offers to charge your credit card in U.S. dollars.
Identification and Reporting Thresholds
Every currency exchange in the United States requires a valid government-issued photo ID: a passport, driver’s license, or state ID. This is true at banks, online vendors, and retail kiosks alike. The requirement comes from the Bank Secrecy Act, the federal anti-money-laundering framework for financial institutions and money services businesses.5Financial Crimes Enforcement Network. The Bank Secrecy Act
For exchanges over $1,000, the provider has to keep a record of the transaction and your identifying information.6Financial Crimes Enforcement Network. A Quick Reference Guide for Money Services Businesses If a cash transaction tops $10,000 in a single day, whether in one visit or several that add up, the institution must file a Currency Transaction Report with FinCEN.7FinCEN. Notice to Customers: A CTR Reference Guide This is routine paperwork, not an accusation. The institution files it. You do not have to do anything.
Declaring Currency at the Border
Carrying more than $10,000 in currency or monetary instruments into or out of the United States triggers a separate requirement: you must file FinCEN Form 105 with U.S. Customs and Border Protection.8Office of the Law Revision Counsel. 31 USC 5316 – Reports on Exporting and Importing Monetary Instruments The $10,000 figure combines everything: U.S. dollars, foreign banknotes, traveler’s checks, and money orders.
For families or groups traveling together, the threshold applies to the combined total, not to each person. A couple each carrying $6,000 is carrying $12,000 collectively and has to file.9U.S. Customs and Border Protection. Money and Other Monetary Instruments
There is no legal cap on how much you can carry. The requirement is disclosure, not restriction. But skipping the form is costly. The government can seize the undeclared funds outright, and you face civil penalties up to the full amount of the unreported currency along with possible criminal prosecution.10Office of the Law Revision Counsel. 31 USC 5321 – Civil Penalties Every year, travelers lose tens of thousands of dollars at the border because they did not know the rule applied to them. It applies to everyone.
Why You Cannot Split Purchases to Avoid Reporting
Some people assume they can dodge the $10,000 reporting rules by breaking a large purchase into smaller ones. Buy $4,000 today, $4,000 tomorrow, and no one files a report. This is called structuring, and it is a federal crime regardless of whether the money itself is clean.11Office of the Law Revision Counsel. 31 USC 5324 – Structuring Transactions to Evade Reporting Requirement Prohibited
The law covers three situations: splitting domestic transactions to avoid Currency Transaction Reports, breaking up international shipments to avoid customs reporting, and helping someone else do either. A basic structuring conviction carries up to five years in prison. If the structuring ties to other illegal activity or involves more than $100,000 within a twelve-month period, the maximum rises to ten years.11Office of the Law Revision Counsel. 31 USC 5324 – Structuring Transactions to Evade Reporting Requirement Prohibited
Intent is what the statute punishes, not the amount. Buy $15,000 in euros at once and the bank files a CTR and everyone moves on. Buy $7,500 Monday and $7,500 Tuesday specifically to stay under the line and you have committed a federal offense even with perfectly clean money. If you need a large amount of foreign currency, buy it in one transaction.
Converting Leftover Currency Back
Most banks and exchange services will buy unused foreign banknotes back from you, but the rate they offer will be worse than the rate you paid. Every exchange has a spread between the buy rate and the sell rate, and you lose on that spread twice: once when you purchase and again when you sell back. Depending on the provider and the currency, the round trip can eat 5 to 10% or more of your money.
The simplest defense is to buy less upfront than you think you need and cover the rest with a card abroad. If you do end up with leftover cash, take it to your bank rather than an airport counter, where the buyback spread is widest. Coins typically are not accepted for exchange, only banknotes, so spend your change before heading home.
