Carta Verde Mercosur Car Insurance: Cost and Coverage

The Carta Verde is one of those items everyone knows they need to get and almost nobody knows what it actually does. It shows up on the document list, it's cheap, it takes minutes to sort out online, and for that very reason it gets treated as empty paperwork.

The problem is that this blind spot gets expensive at two moments: when the traveler thinks they're insured and they aren't, and when they cross into Chile relying on a document that isn't valid there.

In short: the Carta Verde is mandatory third-party liability insurance for driving a Brazilian-plated vehicle in Argentina, Paraguay and Uruguay. It covers damage you cause to third parties, and nothing else: your car, you and your passengers are left out. It isn't valid in Chile, where a different mandatory insurance applies. Prices in 2026 range from about R$ 46 for three days to about R$ 590 for a full year.

What the Carta Verde is, and what it isn't

The Carta Verde came out of a Mercosur agreement and is, in practice, third-party liability insurance recognized among the member countries. Argentina, Brazil, Paraguay and Uruguay are the four.

According to SUSEP, the agency that regulates insurance in Brazil, the coverage includes death, bodily injury, medical and hospital expenses, and property damage caused to non-transported third parties by your vehicle, your trailer or your cargo. The minimum amounts are up to US$ 40,000 per person for bodily injury, with a limit of US$ 200,000, and up to US$ 20,000 per third party for property damage, with a limit of US$ 40,000.

Now the part that almost no sales material highlights. The Carta Verde does not cover:

• your own vehicle, under any circumstances
• you, the driver
• your passengers, because they are "transported third parties"
• theft, fire or weather damage
• towing, roadside assistance and repairs

In other words, anyone who leaves home with the Carta Verde in the folder and nothing else is legal at the border and completely uncovered for their own car. If that's the only policy on the trip, it had better be a conscious choice and not a misunderstanding.

Where it's valid, and the Chile mistake

The Carta Verde is valid in Argentina, Paraguay and Uruguay. That's the list, and it's short.

Chile does not accept the Carta Verde. There, the mandatory insurance for foreign vehicles is a different one, the SOAPEX, which is personal accident insurance and protects people, not the vehicle: driver, passengers and third parties, with coverage for death, permanent disability and medical expenses. Prices in 2026 start around R$ 149 for up to seven days and go to about R$ 299 for thirty to ninety days.

That means anyone doing the classic route of crossing Argentina and entering Chile needs both policies, not one. Mixing them up is one of the most common mistakes people make when planning their first Andes crossing, and it's worth reading the steps for an Argentina to Chile crossing beforehand, because insurance is only one of the things that change at the border.

How much it costs in 2026

The price ranges on the Brazilian market in 2026 look roughly like this:

A tip that helps you save: the minimum coverage is set by the agreement, not by the insurer. Two thirty-day policies with the same legal minimum can differ by almost R$ 90. So comparing quotes makes sense here, and the most expensive one rarely delivers anything beyond customer service.

It's also worth running the numbers the right way. For a forty-day trip, the annual policy is cheaper than two thirty-day packages, and it covers your next trip that year at no extra cost. If your spending plan is still open, the article on how much it costs to drive around South America covers the rest of the lines that go into that spreadsheet.

Where to get it, and why you can't leave it for the border

Here's a rule that catches a lot of people off guard: under the regulation, the insurance must be purchased from an insurer in the country where the vehicle is registered. A Brazilian-plated car buys its Carta Verde from a Brazilian insurer. You can't sort it out on the Argentine side after you've crossed.

In practice, the simplest route is to buy it online before you leave, get the policy as a PDF by email and print it. The digital document is usually accepted, but printing costs nothing and avoids an argument at a border post with no cell signal. It's the same logic as the rest of the paperwork, and the checklist of documents for crossing borders by car brings together everything that goes with it.

There's also a little-known version, the Carta Verde Fronteiriço, for people who live in a border town next to Argentina, Paraguay or Uruguay. It's cheaper, but it limits driving to 50 km inside the foreign territory. It works for the daily life of someone who crosses into the neighboring country and comes back the same day, and it doesn't work for a trip.

When putting the route together, it helps to know which countries the trip will actually cross before buying insurance. In GT Overlander you describe the trip in plain language and the AI builds the route with stops and context for each leg, which makes it clear from the start how many borders are involved.

Frequently asked questions

Is the Carta Verde really mandatory?

Yes, to drive a Brazilian-plated vehicle in Argentina, Paraguay and Uruguay. Driving without it exposes the traveler to a fine and to having the vehicle impounded, and checks usually happen on entry.

Does the Carta Verde cover a crash involving my car?

No. It only covers damage you cause to non-transported third parties. Losses to your own vehicle, to you and to your passengers are left out, and for that you need separate insurance with international coverage.

How far in advance do I need to get it?

Bought online, the policy is issued the same day, usually within minutes. Even so, it's worth handling it a few days ahead, because it's the kind of item that, left for the day before, runs into registration issues, unconfirmed payments or an email that never arrives.

Is it valid in Chile and Bolivia?

No. Chile requires the SOAPEX, which is a different insurance and a separate purchase. Bolivia also has its own mandatory insurance, so a route that includes these countries needs to be checked country by country, not solved with a single document.

The Carta Verde is cheap, fast and meets a real legal requirement. What it doesn't do is replace protection for your own car, and knowing that limit in advance is what keeps you from finding out at the worst possible moment.
