Before you start

Cédula de identidad — a visa alone is generally not enough
Proof of income, pension or source of funds
Proof of a Machala address, usually an Aguas Machala bill
An Ecuadorian mobile number

Step-by-step

1
Get the cédula before attempting a full account
Ecuadorian banks and cooperatives work from the cédula. A visa in your passport is not the same thing, and applications without a cédula are commonly refused without much explanation.

2
Put the Aguas Machala bill in your own name early
The municipal water bill is the standard proof-of-address document here, and a great many rented flats leave it in the landlord's name indefinitely. Sort it in your first weeks, because without it you will be improvising the address evidence a bank asks for.

3
Expect border-town compliance and arrive over-documented
A city an hour from an international land border on a known trafficking corridor applies source-of-funds and identity rules with more care than an inland one, and staff have less discretion. Bring statements, a letter from the sending institution and a clear explanation of the money's origin at the outset rather than producing them piecemeal.

4
Choose between a bank and a cooperativa deliberately
The national banks have the branch networks and better apps. The cooperativas de ahorro y crédito often pay materially more on savings and sit under a different regulator, the SEPS, with a different guarantee arrangement. Understand which supervisor stands behind your money before you choose.

5
Understand the ISD before you move money out
The Impuesto a la Salida de Divisas is charged on funds leaving Ecuador, including outbound transfers and some card transactions abroad. The rate has been reduced repeatedly in recent years — confirm the current figure with the SRI rather than assuming, and factor it in before planning regular transfers home.

6
Do not carry undeclared cash across the border
Cross-border cash movement is regulated and declarable above thresholds set by customs, and the Huaquillas crossing is exactly where that is enforced. Since Ecuador is dollarised and Peru is not, informal money-changing at the border is routine and legally messy. Use the banking system for anything that matters, and check the current declaration threshold with Aduana before travelling with cash.

Things most newcomers don’t know

Dollarisation is worth more here than almost anywhere, because you can see the alternative from the road.

Ecuador has used the US dollar since 2000: no exchange rate to watch, no spread on your salary, no devaluation eroding savings, no parallel market. An hour south, Peru runs a different currency and every cross-border trader in this province spends their working life on that seam. For a resident it means a price quoted in 2026 means the same in 2028 — and it means the informal money-changing you will see at the border is somebody else's problem, not yours.

The ISD is the tax nobody warns you about, and it is charged on money going out.

The Impuesto a la Salida de Divisas applies to funds transferred out of Ecuador and to certain foreign card transactions. For someone paying a foreign mortgage, supporting family abroad or repatriating savings it is a recurring cost that does not exist in most countries. The rate has been cut several times as policy has shifted, so check the SRI's current figure — but do not plan a cross-border money flow without knowing it exists.

Machala's banks are agricultural lenders first, and that shapes what they are good at.

The branch network here exists to finance banana and shrimp production: harvest cycles, input credit, export documentation, letters of credit. If your business touches agro-export, the local expertise is real and useful. If your file is an unusual personal one — a foreign pension, a remote-work income, an inbound transfer from an unfamiliar jurisdiction — expect it to be escalated rather than decided at the counter, and expect Guayaquil to be where it lands.

Cash runs the markets and the port, and carrying it here needs more thought than inland.

Card acceptance is fine in the supermarkets and the malls and thin at the Mercado Central, the Puerto Bolívar stalls and with tradespeople. Since the currency is the US dollar this means real dollar bills in small denominations. In a city with a rapidly worsening security picture, the local habits matter: withdraw inside a bank or a supermarket rather than at a street machine, keep amounts modest, and do not count money in the open.

Common mistakes to avoid

Attempting a full account on a visa without the cédula.
Leaving the Aguas Machala bill in the landlord's name and having no proof of address.
Transferring money out without accounting for the ISD.
Carrying undeclared cash across the Huaquillas border.
Using street ATMs rather than withdrawing inside a bank or supermarket.
