Moving money between the US or Canada and Mexico trips people up more than almost any other logistics question, mostly because Mexico’s banking system doesn’t work the way people expect. There’s no routing number and account number here — there’s a single 18-digit CLABE, and once you understand how it fits into the system, sending and receiving money gets a lot less stressful.
The Apps Expats Actually Use
For transfers under about USD 10,000, Wise and Remitly consistently come out ahead of a traditional bank wire:
- Wise: uses the real mid-market exchange rate with a transparent fee around 0.5–0.7%, and can transfer to a Mexican CLABE in as little as a few hours to two days.
- Remitly: frequently runs zero-fee promotions for first transfers and can be competitive on larger sends, though its everyday exchange rate tends to land a bit behind Wise’s mid-market rate.
- Xoom (PayPal): convenient if you already have PayPal set up, with cash pickup options at Mexican retail partners in addition to bank deposit.
For USD 10,000 or more, a traditional bank wire often nets you more pesos than an app, since wires typically charge a flat fee rather than a percentage. Compare the total cost, not just the advertised fee, before moving a large sum.
How Money Actually Moves Once It’s Here
Mexico’s real-time interbank transfer system is called SPEI (Sistema de Pagos Electrónicos Interbancarios), run by Banco de México. Instead of a routing and account number, every Mexican bank account has one 18-digit CLABE that identifies both the bank and the account — give someone your CLABE and your full name as it appears on the account, and a SPEI transfer between two Mexican banks lands in seconds.
A newer layer called DiMo (Dinero Móvil) lets people send money using just a phone number instead of the full CLABE, which is increasingly how locals split a restaurant bill or pay a plumber. It’s worth having on your phone once you have a Mexican bank account and number.
If you don’t have a Mexican bank account yet, you’re not stuck: several international apps, including Wise and Revolut, can send directly to any valid CLABE from abroad, and some services will verify your identity with just a passport rather than requiring the CURP and RFC that most Mexican banks ask for. That said, opening an actual Mexican account is still worth doing if you’re staying long-term — see the link below.
Exchange Rates and the 2026 Remittance Tax
Whatever app or bank you use, always compare against the mid-market rate (the one you’d see on Google or XE) rather than trusting an advertised “no fee” claim — the spread between the mid-market rate and what a provider actually gives you is where most of the real cost hides. As of 2026, a 1% US federal excise tax also applies specifically to remittances funded with cash, money orders, or cashier’s checks; transfers funded from a bank account or card are exempt, which is one more reason to send electronically rather than with cash.
Cash and ATMs
For day-to-day spending, withdrawing pesos from a Mexican ATM with a US or Canadian debit card is usually cheaper than exchanging cash at a casa de cambio, but check your home bank’s foreign withdrawal fee first — some charge a flat fee per withdrawal on top of whatever the Mexican ATM charges. Use bank-affiliated ATMs (inside a branch or attached to one) over standalone airport or street machines, which tend to carry worse rates and higher fees. And let your home bank know you’ll be transacting in Mexico before you travel, so a routine withdrawal doesn’t get flagged as fraud.
Where to Go From Here
If you haven’t opened a Mexican account yet, Opening a Bank Account in Mexico as a Foreigner walks through what’s required and which banks work best for expats. And since a CURP is often part of that process, RFC, CURP, INE, IMSS: Which Document Do You Actually Need? is worth reading first so you’re not caught off guard at the bank.
