Border crossing open at night with illuminated lanes

Not every border crossing is open around the clock. If you are crossing early or late, here are the hours for San Diego’s three ports of entry so you do not arrive to a closed gate.

Quick answer: San Ysidro is open to passenger vehicles 24 hours a day, 7 days a week. Otay Mesa passenger hours are more limited (generally early morning to late night), and Tecate has the most restricted hours. Always confirm current hours with CBP before an early or late crossing.

San Ysidro hours

San Ysidro never closes for passenger vehicles – it is open 24/7 in both directions. That makes it the safe choice for overnight trips, very early starts, or late returns. (Our drive-through insurance office at the last exit before the border is also open 24/7, so you can get covered any time.)

Otay Mesa hours

Otay Mesa’s passenger vehicle lanes typically run from the early morning until late at night rather than 24 hours, with commercial cargo lanes on a separate schedule. If you plan to cross at Otay Mesa outside normal daytime hours, check the current schedule first.

Tecate hours

Tecate has the most limited hours of the three, generally operating from early morning to late evening. Because it is a smaller, rural crossing, do not count on it overnight – if your timing is uncertain, San Ysidro is the reliable fallback.

Always verify before you go

Hours can change for holidays, construction, or staffing. US Customs and Border Protection lists current port-of-entry hours on its website. Check it alongside the live wait times when you plan your crossing.
