"There's no single minimum age in Costa Rica — it's set by supplier, not country. Vamos, Sixt, and Europcar take you at 18. Alamo, National, Hertz, and Avis hold at 21. Adobe wants 23, no exceptions."
Most destinations set one age floor and charge a surcharge below it. Costa Rica doesn't work that way — the minimum age depends on which supplier you book, and the gap between them is wide enough to change which companies are even an option. Vamos, Sixt, and Europcar take drivers from 18. Alamo, National, Hertz, and Avis hold the line at 21. Adobe wants 23, with no surcharge tier that gets you in younger.

Age minimums and what they mean for your trip
Vamos, Sixt, and Europcar will rent to drivers as young as 18 — each handles the added risk differently rather than turning younger drivers away. Alamo, National, Hertz, and Avis all hold their floor at 21, with a young driver fee applying on top. Where published, that fee converges around $10–$20 per day. Adobe is the outlier on the strict end: 23 is the minimum, full stop, with no surcharge tier that gets a 21 or 22 year old into a car.
These are company-wide policies, not airport-specific ones — the minimum age and surcharge are the same whether you're flying into San José (SJO) or Liberia (LIR).
| Age | Surcharge | What happens |
|---|---|---|
| Under 18 | Not eligible | No supplier in Costa Rica rents to drivers under 18. No exceptions. |
| 18-20 | $10-$20/day | Only Vamos, Sixt, and Europcar will rent to you. The other four major suppliers — Alamo, National, Hertz, Avis, and Adobe — require at least 21. |
| 21-22 | $10-$20/day | Adds Alamo, National, and Hertz. Avis's published surcharge tier ends at 23, so this age still qualifies there too. Adobe is still off the table — their 23 minimum has no surcharge tier below it. |
| 23-24 | $10-$20/day | Every major supplier is open, including Adobe. A young driver fee still applies at most brands until 25. |
| 25 and over | No surcharge | Full access at every major supplier. No age-related fees or restrictions. |

If you're 18 to 20
Vamos, Sixt, and Europcar are your options. Vamos handles the added risk by doubling the CDW deductible for drivers 18–20 rather than charging a separate fee. Sixt and Europcar add a young driver surcharge instead, and Sixt sets a higher floor on some vehicle classes — worth checking if you have a specific car in mind. Either way, the other four major suppliers won't take the booking at this age, regardless of price. For a full breakdown of which US suppliers rent to 18-year-olds and what it costs, see the rent at 18 guide.
If you're 21 to 22
Adobe is off the table, but everyone else is open. Alamo and Avis both publish a $10/day young driver fee in their Costa Rica terms — Avis's surcharge tier specifically covers 21 to 23, so it applies here too. National typically mirrors Alamo's rate since both run under the same Costa Rica franchise. Hertz also charges extra at this age but doesn't publish a fixed Costa Rica rate, so expect somewhere in the same $10–$20/day range and confirm the exact figure at booking. Vehicle class restrictions can apply at this age, so confirm the car you want is actually available before booking.
If you're 23 or 24
Every major supplier is open at this point, Adobe included. The young driver fee still applies at most brands until 25, so the savings from waiting two years are mostly about which suppliers are on the table, not the surcharge itself.
Why Adobe's floor doesn't bend
Most suppliers price young drivers into the rental rather than excluding them — pay more, get the car. Adobe doesn't offer that trade. Drivers under 23 aren't given a surcharge option; the reservation simply isn't available to them, regardless of the price someone might be willing to pay at the counter.
The young driver fee and mandatory insurance are separate
The young driver fee doesn't replace or reduce Costa Rica's mandatory third-party liability coverage — they're two different line items, and both apply together if you fall under a supplier's age threshold. For the full insurance breakdown, see the Costa Rica rental guide.
The verdict
If you haven't booked yet: Sort your supplier before you sort your age bracket. If you're 21 or 22, Adobe is off the table no matter the price — check Alamo, National, Hertz, or Avis instead, and budget for their young driver fee. If you're 18–20, Vamos, Sixt, and Europcar are the ones worth comparing. Factor the surcharge into your total cost from the start so it isn't a surprise at the counter.
If you're already booked: Confirm your exact age against the supplier's stated minimum — not the general "21-25" range you might have seen elsewhere. If you're under your supplier's floor, the reservation won't be honored regardless of what a third-party site showed at checkout. Check your booking confirmation for a young driver fee line item; if it's not listed, ask the supplier directly before you fly.
If you've been charged a fee you weren't expecting: Go through your booking platform first if you used one — they can usually confirm whether the fee was disclosed at booking. If you booked direct, contact the supplier in writing with your rental agreement and give them a week to respond before escalating to your card issuer.

- Adobe's 23 minimum has no workaround — no surcharge, no deposit increase, no exception gets a 21 or 22 year old into one of their cars
- A young driver fee is separate from the security deposit — expect both if you book under 25
- Adding a younger traveler as an additional driver doesn't dodge the age rules — every major supplier applies the same minimum age and surcharge to additional drivers as the primary renter

Frequently asked questions
What is the minimum age to rent a car in Costa Rica?
It depends entirely on the supplier. Vamos, Sixt, and Europcar rent from 18. Alamo, National, Hertz, and Avis set their floor at 21. Adobe requires 23, with no exceptions at any price.
Can I rent a car in Costa Rica at 18?
Yes, at a handful of suppliers — Vamos, Sixt, and Europcar all rent from 18. Vamos doubles the CDW deductible for drivers 18-20 instead of charging a separate surcharge; Europcar and Sixt add a young driver fee instead.
Can you rent a car in Costa Rica under 25?
Yes, at every major supplier — none of them set 25 as a hard floor. What changes is the surcharge: suppliers with a 21 minimum (Alamo, National, Hertz, Avis) typically charge a young driver fee for renters 21-24, and the suppliers with an 18 minimum apply a similar fee from 18-24.
How much is the young driver surcharge in Costa Rica?
Alamo and Avis both publish $10/day in their Costa Rica terms — Avis's tier runs 21 to 23, Alamo's runs 21 to 24. National typically mirrors Alamo's rate. Hertz charges extra too but doesn't publish a fixed Costa Rica figure, so budget for somewhere in the broader $10-$20/day range reported across suppliers and confirm the exact amount at booking. It's charged per rental day, not per calendar day, so a multi-week trip carries the fee the whole way through.
Can a 25-or-older friend book the car and add me as an additional driver instead?
No — every major supplier requires additional drivers to meet the same age minimum and pay the same young driver fee as the primary renter. Alamo and Avis both state this explicitly in their Costa Rica terms. If you're 22 and your 27-year-old friend books the car, you'll still owe the under-25 surcharge to be added as a driver, and some suppliers charge a separate flat additional-driver fee on top of that. The <a href="/tips/additional-driver-fee/">additional driver fee guide</a> covers how that second charge generally works — note that the loyalty-program waivers it describes are US-specific and may not apply to a Costa Rica rental.
Why does Adobe require drivers to be 23 when other suppliers allow 18 or 21?
Adobe sets 23 as a flat company policy with no surcharge tier below it — drivers under 23 aren't offered the option to pay more to qualify. Suppliers with lower floors instead price the added risk into a young driver fee rather than excluding the age group outright.
Does the young driver fee apply on top of the mandatory insurance?
Yes. The young driver fee and Costa Rica's mandatory third-party liability coverage are separate charges — one isn't a substitute for the other, and both apply if you're under the relevant age threshold.
I already have a booking — what should I check before pickup?
Confirm your exact age bracket against the supplier you booked, since the fee tiers shift at 21 and 25 depending on the brand. If you're under the supplier's stated minimum, the booking won't be honored at the counter regardless of what a third-party site showed at checkout.
