Secure a slot before the 3-minute booking window closes.
SENTRI allows expedited crossing at US–Mexico land border ports of entry. It's essential for daily cross-border commuters in cities like San Diego and El Paso. Appointment slots — particularly at Otay Mesa and San Ysidro — disappear in a 3-minute window. Our automated scanners connect directly to the CBP to outpace the crowds.

ApptHelper was built by a daily San Diego border-crosser who got tired of waking up at 3 AM to check for SENTRI appointments at San Ysidro and Otay Mesa. Generic scanners don't understand the urgency of the southern border. Our scanners are deeply optimized to grab border slots within seconds of them opening.
