Jack In The Box Headquarters Address, Corporate Office Location, and Contact Details

About

Jack in the Box, Inc. (NASDAQ: JACK) is an American fast food restaurant chain headquartered at 9357 Spectrum Center Boulevard, San Diego, California 92123 — in the Kearny Mesa commercial corridor of northern San Diego, where the company has maintained its headquarters since its founding in 1951. Jack in the Box was founded on February 21, 1951, by Robert O. Peterson in San Diego, California — opening as a drive-through hamburger stand in the then-nascent fast food industry, making it one of the earliest fast food chains in the United States and a pioneer of the drive-through format.

Jack in the Box’s menu is one of the broadest in the fast food industry — encompassing burgers, tacos (famously the two-for-$1 tacos that have become cult items), egg rolls, curly fries, milkshakes, and full breakfast items — with 24/7 operations that differentiate the brand in markets like Southern California, Texas, and the Pacific Northwest. The company operates 2,200+ locations concentrated in 21 western and southern US states.

In March 2022, Jack in the Box, Inc. acquired Del Taco — the Mexican-American fast food chain — for approximately $585 million, making Jack in the Box, Inc. a dual-brand restaurant company for the first time. Del Taco’s operational headquarters is at 25521 Commercentre Drive, Lake Forest, California 92630 — a separate facility from Jack in the Box’s San Diego corporate campus.

About the San Diego HQ: Jack in the Box’s headquarters at 9357 Spectrum Center Blvd is located in the Kearny Mesa commercial district of northern San Diego — a major office and light industrial zone in San Diego County that houses numerous technology, defense, and food service corporate operations. San Diego is the birthplace of Jack in the Box and has remained the company’s home for 70+ years — a continuity of place that reflects the deeply California and West Coast character of the Jack in the Box brand. The company’s 1993 E. coli outbreak — in which undercooked hamburger patties contaminated with E. coli O157:H7 killed 4 children and sickened 700+ people — became one of the most consequential food safety incidents in US history, directly leading to USDA and FDA reforms that redefined ground beef safety standards and HACCP (Hazard Analysis Critical Control Points) requirements for the entire US food service industry.
