What your rental agreement allows (or doesn't)
A rented campervan legally remains the property of the rental company. Crossing a border with it without their written consent can lead to an outright refusal at the border crossing, or even a breach of contract. Most North American rental companies therefore require prior authorization, to be requested several weeks before departure — never at the counter on pickup day, when no one will have the time or the authority to process it.
Heading to Canada
This authorization is sometimes granted free of charge for a crossing into Canada. Rental companies are well acquainted with this route, since cross-border rentals to Canada are common.
Heading to Mexico
The situation gets noticeably more complicated. Many rental companies flatly forbid entry into mainland Mexico, allowing only Baja California — Baja California and Baja California Sur — due to the local insurance regime specific to that region. In this case, authorization is more restrictive than for Canada: it can be limited to certain dates, to a specific route, or refused outright depending on the agency's policy.
The Nomad tip
Request this authorization in writing as soon as you book, not afterward: some rental companies refuse to process it once the contract is signed, even if it's several weeks before departure.
Documents to have with you before hitting the road
Once you have the rental company's authorization, there's still the question of the paperwork to present at the border crossing. It's best to prepare it in two paper copies: not every border agent is equipped, or willing, to check a file on your phone.
Here's what you need to have on you:
- the original rental agreement or a certified copy;
- a certificate of insurance explicitly covering the country you're visiting;
- the vehicle's registration certificate;
- a valid passport;
- your original driver's license — and, if it isn't written in Latin characters, an international driving permit or a certified translation, generally required.
The exit authorization issued by the rental company deserves a separate mention. Always print it: some border agents ask for a paper version, and a document stuck in an email inbox with no signal is no use when it's requested.
Which vehicle for this trip?
For a border crossing, it's best to travel in a manageable van, easier to present and maneuver at border crossings where inspection lanes can sometimes be narrow.

Keep these documents together, accessible without having to search through the whole campervan — a passenger who has them at hand saves a lot of time at the crossing.
At the border: what changes depending on the direction
Having the documents in hand doesn't guarantee the same experience on both sides. The inspection itself, what's asked of you and what's refused, differs sharply depending on which border you're crossing.
Entering Canada
On the northern side, the crossing stays close to what you already know by car: a standard immigration and customs check, questions about the length of your stay, verification of the documents presented. One point deserves particular attention in a campervan: declaring food and fresh produce on board. Fruit, vegetables, meat or dairy products stored in the fridge must be declared, or you risk a fine. Aside from this declaration and the documents already mentioned, no vehicle-specific paperwork is required.
Entering Mexico via Baja California
Baja California — Baja California and Baja California Sur — forms a so-called free zone, where the Temporary Vehicle Import Permit (TIP), mandatory for driving in the rest of Mexico, is generally not required. This simplifies the crossing at posts like San Ysidro/Tijuana, without easing the insurance requirement: Mexican coverage is mandatory, since your US policy is no longer recognized once you cross the border.
The Nomad tip
Don't rely on your US insurance to drive in Mexico, even in Baja California: take out a Mexican policy before you leave. It can be arranged online in a few minutes and avoids any unpleasant surprise in the event of a checkpoint or an accident.
Insurance and budget to plan for
A border crossing adds line items to the budget that are too often forgotten, on top of the rental price. They're not huge individually, but they add up and are hard to negotiate once you're there.
First line: the exit authorization fee charged by some rental companies, typically in the $50–150 range. This amount generally covers internal paperwork and, sometimes, an adjustment to the rental company's own coverage for the duration of the trip abroad. It varies widely from one agency to another, and some don't charge it at all for a crossing into Canada — all the more reason to ask for a written quote before booking.
Second line, specific to Mexico: temporary Mexican insurance, budgeted at around $15 to $30 a day. It's purchased online before departure, which avoids the — sometimes long — queue at the border crossing and allows you to compare offers calmly rather than under pressure at a broker's counter set up right before the crossing.
The Nomad tip
Budget for these costs as soon as you book, not the night before departure: an exit authorization needs to be requested several weeks ahead, and Mexican insurance bought in a panic at the border almost always costs more than the same policy taken out online a week beforehand.
The return to the United States and other points to watch
Crossing the border on the way out is only half the administrative journey. The return involves a new inspection, this time by US Customs and Border Protection (CBP), and there's no guarantee it will be faster than the initial crossing. A secondary inspection of the vehicle is still possible: the agent may ask to open the storage bays, the fridge, the cupboards, to check for prohibited items or undeclared goods. This thorough check, when it happens, takes time — sometimes far more than expected.
Wait times themselves vary widely depending on the time of day and which crossing you choose. A return late in the day or on a Sunday evening, when everyone is heading home, can turn twenty minutes into several hours. No border crossing guarantees a fixed wait time, and the differences from one day to the next at the same crossing can be considerable.
The practical consequence is simple: never schedule a return flight for the same day as your border crossing. Build in a night's margin, or even two if your itinerary allows, rather than betting on a smooth crossing to catch a flight. A campervan stuck in an unexpected queue doesn't negotiate with a boarding gate.
The Nomad tip
If your return flight is within 24 hours of your border crossing, return the vehicle the day before rather than the same day: this absorbs any delay at the crossing without putting your flight at risk.
Frequently asked questions
Can you take a rental campervan out of the United States?
Only if the rental company has authorized it in writing before departure. The vehicle remains their property, and crossing a border without their agreement risks a refusal at the border crossing or a breach of contract. This authorization needs to be requested at the time of booking, never on pickup day.
Do you need specific insurance to enter Mexico?
Yes. A US policy isn't recognized once you've crossed the border, even in Baja California. Temporary Mexican insurance is required, budgeted at around $15 to $30 a day, and should be purchased online before departure rather than at a broker's counter at the border.
Is the Temporary Vehicle Import Permit (TIP) mandatory?
Not for entry limited to Baja California — Baja California and Baja California Sur — where this free zone generally exempts you from the TIP required in the rest of Mexico. This is one of the reasons many rental companies limit their exit authorization to this region alone.
What documents are requested at the border crossing?
The rental agreement, a certificate of insurance explicitly covering the country being visited, the vehicle's registration certificate, a valid passport, the original driver's license — with a certified translation or international driving permit if needed — and the rental company's exit authorization, printed on paper.
