SENTRI is a U.S. Customs and Border Protection (CBP) Trusted Traveler program that gives pre-approved, low-risk travelers their own lanes when they cross back into the United States from Mexico at land ports. In San Diego, that means the dedicated SENTRI lanes at San Ysidro and Otay Mesa, for both drivers and pedestrians. The application fee is $120 for five years.
If you cross a few times a month for work, family or dentist visits in Tijuana, the program usually pays for itself in saved hours. If you cross once a year, a passport card and patience may be enough. Here's how SENTRI works, how to apply and the rules that trip people up.
What SENTRI is and who it's for
The name stands for Secure Electronic Network for Travelers Rapid Inspection. CBP vets you in advance, through a background check and an in-person interview, so the inspection at the border can be faster. SENTRI only applies northbound, when you enter the U.S. Going south into Mexico, you follow Mexican procedures like everyone else.
U.S. citizens, lawful permanent residents and citizens of other countries, including Mexico, can apply. Approval is never automatic. CBP can deny an application, and it can revoke membership for a violation at the border.

SENTRI, Global Entry and Ready Lane
People mix these up all the time. Global Entry is built for international air arrivals. SENTRI is built for the southern land border. Ready Lane, at ports like San Ysidro, is a faster general lane for anyone carrying an RFID-enabled document such as a U.S. passport card or an enhanced driver's license, with no application.
Benefits overlap in places. TSA lists SENTRI among the programs whose members can use TSA PreCheck at airport security, and CBP extends some Global Entry benefits to certain SENTRI members depending on citizenship. Mexican nationals, for example, apply separately for Global Entry. Check CBP's program comparison for your situation before counting on any overlap. If you also fly out of Lindbergh Field often, our guide to San Diego airport parking covers the airport side.
What it costs
On April 2, 2024, CBP published a final rule in the Federal Register that harmonized Trusted Traveler fees. Starting October 1, 2024, the SENTRI application fee is $120, the same as Global Entry. The fee is nonrefundable, even if CBP denies your application.
Minors under 18 are exempt from the application fee when a parent or legal guardian is already a member or applies at the same time. Membership lasts five years from approval.
Registering a vehicle is a separate step in your account, and the cost of adding vehicles has changed under past rules. Look at the current amount inside the Trusted Traveler Programs system before you register a car.

How to apply, step by step
The process runs through the Trusted Traveler Programs website, operated by the Department of Homeland Security. Expect it to take a while; conditional approval and interview availability vary.
1. Create your account and apply
You sign in with a Login.gov account, fill out the SENTRI application and pay the fee online. Have your passport or other citizenship and identity documents, your address history for the past five years and your employment history ready. Small inconsistencies slow things down, so take your time.
2. Wait for conditional approval
CBP runs a background check. If you pass, your account shows conditional approval and invites you to schedule an interview. Check your account and email often, since the message is easy to miss.
3. Do the interview
CBP lists an enrollment center in Otay Mesa at 9725 Via De La Amistad, San Diego, CA 92154, open by appointment only. Bring the documents your account asks for, including the originals of what you uploaded. The officer reviews your information, takes fingerprints and a photo, and asks a few questions about your travel.
4. Activate your card and register your car
Once approved, your card arrives by mail. Activate it as instructed in your account before you use it. To drive through the SENTRI lanes, add your vehicle in the system and wait until it shows as approved. Using the lane in an unregistered car is a violation.
Using the SENTRI lanes in San Diego
By car
At San Ysidro and Otay Mesa, the SENTRI vehicle lanes have their own entrances. Approach with every card in the car ready, since card readers pick them up as you near the booth. The officer may still ask questions or send you to secondary inspection; membership speeds up the line, it doesn't skip inspection.
Otay Mesa is the closer crossing for much of the South Bay. Our guide to Chula Vista covers the city that sits between downtown and both ports.
On foot
Both San Ysidro and Otay Mesa have pedestrian SENTRI lanes, separate from the general line. Many people who live near the border walk across. The UC San Diego Blue Line trolley ends at San Ysidro, a few steps from the pedestrian crossing; see our San Diego Trolley guide for how to ride it.
Checking wait times
CBP publishes estimated wait times by port and lane type on its Border Wait Times site and app. Compare the SENTRI, Ready Lane and general lanes before you leave. Times change by hour and day, and holiday weekends can surprise even members.
Is SENTRI worth it for you?
It comes down to how often you cross northbound and how long you usually wait. A $120 fee spread over five years costs little compared with hours in a general lane, if you cross regularly. If you only go south a few times a year, Ready Lane with a passport card may be enough.
Before you apply, ask yourself three things. Can you keep your address, documents and vehicle information current for five years? Will every regular passenger in your car also enroll? And are you comfortable with a zero-tolerance approach to declarations? If the answer is yes, SENTRI is one of the most useful documents a San Diego commuter to Mexico can carry.
Rules and fees change, so treat CBP and the Trusted Traveler Programs website as the final word. This guide explains the general process and is not legal or immigration advice.
