What Is Carpool Parking? How Carpool Spots and Lots Work

What is carpool parking? It is parking reserved or made available for people traveling together in one vehicle, often to support shared commuting and reduce the number of cars. At BART, eligible carpoolers can use the current Carpool Parking program through the BART Official App, buy parking, and park in Reserved sections instead of separate dedicated carpool stalls. The program is available at all BART stations with Reserved parking except Glen Park, Pittsburg Center, Milpitas, and Berryessa/North San Jose, and the app-based feature runs from 4 AM to 10:15 AM, as of September 2026.

What Carpool Parking Means

Carpool parking supports a shared ride, rather than every driver. In plain terms, it is parking tied to a shared ride, not a parking category that applies to every driver.

Carpooling means sharing a car journey so that more than one person travels in the vehicle.

Related Terms

A park and ride, also called a commuter lot, is a parking lot where people may leave a vehicle and transfer to public transport or join a carpool for the rest of the trip. By contrast, a parking facility used only to meet a carpool, without public-transport connections, may be called a “park and pool.”

Kiss and ride means something different again. A kiss-and-ride area is for brief passenger drop-offs or pickups, while park-and-ride or park-and-pool arrangements involve leaving the vehicle parked while the traveler continues by transit or carpool.

Programs that support carpool parking can take different forms. One model sells parking access to Reserved sections of station lots through an app, while another relies on Park & Ride lots and ride matching to help people find others to share a trip with. The Bay Area Commuter Carpool Network is an example of that kind of support, since it connects commuters, provides access to carpool ride matching and trip rewards, and lets users view information from relevant agencies through one account.

Parking for a vanpool is also separate from carpool parking. The Bay Area Vanpool Program offers a $600 monthly discount on Commute with Enterprise vanpool rentals, as of September 2026, and can help participants sign up for discounted parking in San Francisco and Oakland. Carpool parking does not mean all of those programs at once; it simply refers to parking connected to shared travel.

How BART Carpool Parking Works

The program follows BART’s established app based parking process. Eligible users no longer look for a separate dedicated carpool stall, because BART has phased those out.

Access starts in the official mobile app on an iOS or Android device. After downloading the app, a rider creates a profile, adds a Clipper card number, and sets up a parking payment method. Credit card, debit card, Venmo, and PayPal are the payment methods BART lists for the program.

Next, the user selects “parking/carpool” to receive a Carpool ID. That ID is stored in the app, belongs to one person, and stays the same. Another person may help create the profile on a smartphone, then write down the Carpool ID, but BART still says a smartphone is required because account creation and ID issuance happen only in the official app.

Download the official BART app on an iOS or Android device.
Create a profile and add a Clipper card number.
Add a parking payment method from the options BART lists.
Select “parking/carpool” to generate a personal Carpool ID.
Park as directed when available.
Have both carpool members tag through the faregate as required by the program.

Availability is managed station by station, and BART may limit the number of carpool permits sold at each location. The app shows how many permits remain, so riders can see whether a station still has room before they head there. When a carpool option is sold out, BART says not to park in the Permit or Reserved area and to use Daily Fee parking or another station instead.

Station Access and Timing

Program access is not universal across the full system. BART identifies participating stations. Reserved sections are described as typically better located and having more availability, and BART says Reserved or Permit areas fill later than Fee areas, which gives carpoolers more flexibility in arrival time.

Faregate use is part of the process, not just the parking purchase. The carpool page says the app is tied to faregate verification, and it also notes that the feature operates from 4 AM to 10:15 AM as of September 2026. BART employees, law-enforcement officer pass holders, and Airport Employee Discount pass holders may also use the app to pay for parking, but the current carpool program itself still runs through the same mobile-app workflow.

Where the Program Is Available

At participating stations, the program applies to eligible carpoolers.

Beyond that, at those locations, the app may show whether permits remain for a station, since BART can limit how many carpool permits are sold. When permits are still available, the app is the place to complete the purchase and secure access for that day.

When a Station Sells Out

If the app shows that carpool parking is sold out, drivers should not enter the Permit/Reserved area. They should use another parking option.

Across the system, that rule matters because a carpool permit bought through the app is required for BART Reserved and Permit areas. Paper carpool permits are no longer accepted, including paper permits once obtained through 511.org, so a station without remaining app permits is not open to those older credentials.

How Access Is Enforced

Enforcement starts with the permit record tied to the app and continues at the faregate. BART requires every person in the carpool to have a Carpool ID, and both members must tag the faregate during the trip, while the parking itself is tied to the app-based permit for the Reserved area.

That visibility helps drivers decide before arrival whether a participating station can accept another carpool vehicle or whether a different parking option is needed.

The practical question is not whether a lot is labeled for carpools, but whether the app shows room and the Reserved area is open.

Carpool Parking Compared with Other Parking Options

A park and ride lot can also be called a commuter lot, and a parking facility used only to meet a carpool, without public-transport connections, may be called a park and pool.

Kiss and ride is different again, because that setup is for short passenger drop-offs or pickups rather than for leaving a vehicle parked. By contrast, a park and ride or park and pool arrangement keeps the vehicle parked while the traveler continues the trip, which makes those systems closer to carpool parking than a kiss-and-ride area is.

Vanpooling is not the same as carpooling in the Bay Area transportation context. 511.org defines a vanpool as a group of 7 to 15 people commuting together in a large vehicle driven by one of the participants, and the Bay Area Vanpool Program offers a $600 monthly discount on Commute with Enterprise vanpool rentals as of September 2026.

How the Options Differ

Option	What It Is	How It Differs From Carpool Parking
Park and ride	A lot where people leave a vehicle and continue by transit or by carpool.	Carpool parking is tied to shared commuting, while park and ride can also support transit transfers.
Park and pool	A parking facility used only to meet a carpool, without public-transport connections.	Carpool parking may be part of a station lot system such as BART’s Reserved areas.
Kiss and ride	A brief drop-off or pickup area.	Carpool parking involves leaving the vehicle parked.
Vanpool	A group of 7 to 15 people commuting together in a large vehicle.	Carpool parking is not the same as parking for a vanpool vehicle.
General parking system	An ordinary parking program, such as UC Davis’s app-paid daily and monthly parking.	Carpool parking is associated with people traveling together in one vehicle.

UC Davis shows how a general parking system can be organized around pay-by-phone tools, daily and monthly parking, and License Plate Recognition, which scans license plates and compares them with a database to help collect parking fees. Its page also says the university changed parking operations in January 2021 to modernize campus parking demand and support sustainability goals.

Payment, IDS, and App Requirements

The app handles the required setup. It also provides parking access.

To get started, each user must download the BART Official App on an iOS or Android device and create a profile. After that, the app asks for a Clipper card number and a payment method.

Carpool ID Rules

A Carpool ID is created by selecting “parking/carpool” in the app, and that ID stays in the app for the person who created it. Because the ID is specific to each person and remains the same, the traveling partner must enter the valid, correct Carpool ID when the carpool is used.

Both members of the carpool must enter the faregates within 20 minutes of finishing payment. Payment must happen either 10 minutes before or 10 minutes after entering the faregates, so timing matters as much as the app setup.

Someone without a smartphone can use another person’s smartphone to create a profile and write down the Carpool ID. BART still says a smartphone is required to obtain the ID because account creation and ID issuance happen only in the official mobile app.

What the App Tracks

Once a Carpool ID is used, the person tied to that ID gets a notification each time. If the ID is used without permission, that person may dispute the use, and BART says it will block accounts after warnings for misuse.

Access follows the stated schedule. Within that window, the app also shows how many permits remain at each station, which helps users see whether parking is still available before they commit to the trip.

Older BART Parking Programs and Current Limits

Older BART parking methods no longer apply for carpool parking, and riders now need the current app-based permit system. Paper carpool permits, including permits that were obtained through 511.org, are no longer accepted in BART Reserved or Permit areas.

Previously, some riders used magstripe tickets or paper permits to deal with parking payment, but those options have been retired for BART carpool parking. Today, BART says parking access comes through the BART Official App, not through a paper pass or a magstripe ticket.

What No Longer Works

Instead, riders must use the app for parking transactions and profile setup. Clipper cards do not support BART parking payment, and BART says Clipper is used here for faregate verification rather than for paying the parking fee.

Another change affects the physical layout of the lots. Dedicated carpool stalls have been phased out, so app users park in Reserved sections rather than in a separate carpool space.

What Current Limits Mean

Even so, the current program still has clear limits. If carpool parking is sold out, drivers must follow BART’s stated alternative parking guidance.

Finally, not every station participates, so riders need to check availability before leaving home in advance. At the same time, every person in the carpool must have a Carpool ID, and both passengers must tag into the faregates with the Clipper number stored in their own app profile.

What the Program Does Not Cover

Carpool parking does not explain every rule a rider might want before planning a trip. Prices, enforcement penalties, and non-BART carpool parking rules are not given in the available information, so the limits of the program stay narrow.

Missing Cost Details

Pricing details are incomplete.

Penalties are also not listed. No fine amount, towing rule, or other enforcement consequence appears in the available information for someone who parks in a Permit or Reserved area without the proper carpool permit.

Outside BART Parking Rules

Other parking systems are not covered in the same way. UC Davis parking information describes campus parking, daily rates, monthly employee parking, and license plate recognition, but it does not give carpool-space rules in the available information.

Regional carpool and Park & Ride resources are broader, yet they are not a substitute for BART parking instructions. The Bay Area network helps commuters with ride matching and trip rewards, and it points people to more than 150 free Park & Ride lots, but the available information does not provide a BART permit price, a BART penalty schedule, or a full set of non-BART carpool-parking rules.

Readers should treat that gap carefully. For BART parking, the current app-based permit rules control station use, while the available information leaves other parking questions unanswered.

This guide does not set a minimum rider count on this page; for this page, carpool means the ride is shared, not a solo drive.

Frequently Asked Questions

What Is Carpool Parking?

Carpool parking is parking reserved or made available for people who travel together in one vehicle. It supports shared commuting and can help reduce the number of cars on the road.

How Does BART Carpool Parking Work?

BART offers carpool parking only through the BART Official App. Eligible carpoolers buy parking in the app, park in Reserved sections, and both riders must tag into the faregates within 20 minutes of payment.

Which BART Stations Do Not Offer the Carpool Program?

The BART carpool program is available at all stations with Reserved parking except Glen Park, Pittsburg Center, Milpitas, and Berryessa/North San Jose. Sold-out locations have separate parking restrictions.

Do All Carpool Riders Need a Carpool ID?

Yes. Every person in the carpool must have a Carpool ID, and each person must use the Clipper number registered in their own app profile when entering the faregates. BART says one smartphone can hold multiple accounts if users log out and create separate profiles.

Can Riders Still Use Paper Carpool Permits at BART?

No. BART no longer accepts paper carpool permits, including paper permits previously obtained through 511.org. A carpool permit obtained through the app is required to access BART Reserved and Permit areas.

How Is Carpool Parking Different from Park and Ride?

Carpool parking is tied to a shared ride, while a park and ride lot is a place where people leave a vehicle and then continue by public transport or join a carpool. A parking facility used only to meet a carpool, without public-transport connections, is called a park and pool.

For BART riders, carpool parking now means using the official app, a valid Carpool ID, and the station’s Reserved area rather than a dedicated stall. The program is designed around shared commuting, app-based payment, and faregate verification, with station-specific limits and sold-out rules. Outside BART, Bay Area Park & Ride lots and carpool matching resources can support shared trips, but they do not replace BART’s own parking rules.
