AutoZone, Inc. is an American retailer of aftermarket automotive parts and accessories, the largest in the United States.

Founded in 1979, AutoZone has 7,140 stores across the United States, Mexico, Puerto Rico, Brazil, and the US Virgin Islands.

[1][2] Originally a division of Memphis-based wholesale grocer Malone & Hyde, the company was known as Auto Shack.

ALLDATA, a software company based in Elk Grove, California that provides automotive diagnostic and repair information, was acquired.

[13][14] At the commencement of fiscal 1999, AutoZone made another acquisition by purchasing 100 Express stores from The Pep Boys—Manny, Moe & Jack.

[15] The company began a process of internationalization with their first store abroad, which opened in Nuevo Laredo, Mexico.

[18] In 2002, AutoZone developed a network of "hub, feeder, and satellite" stores to have more product in the market area, while reducing inventory investment.

[22] In 2007, Bill Rhodes, then 42, was named chairman, president and chief executive officer of AutoZone, Inc. on June 6.

[24][25] On December 15, 2011, ALLDATA LLC, an operating unit of AutoZone, expanded its direct presence in Canada to better serve its growing customer base.

[28] In December 2012, AutoZone purchased AutoAnything.com, an e-commerce leader in aftermarket automotive parts based in San Diego, California.

[28][29] By April 2017, AutoZone had been the largest retailer of automotive parts in North America for three consecutive years.

[1] Since October 1995, AutoZone has been headquartered in its J.R. Hyde, III Store Support Center (SSC), a 270,000-square-foot (25,000 m2), eight-story building in Downtown Memphis, Tennessee.

The building has the capability to withstand a 9.0 magnitude earthquake because it has a special base isolation system that had a price tag of $950,000.

[39] In 2004, AutoZone celebrated its 25th anniversary and announced a corporate sponsorship agreement with auto racing association NASCAR.

[40] The AutoZone Liberty Bowl, alongside the College Football Playoff Foundation donated $250,136.03 to the St. Jude Children's Research Hospital.

[42] They are an official sponsor of Bellator MMA, the world's second largest Mixed Martial Arts promotion.

[43] AutoZone faced a lawsuit for gender discrimination in which the plaintiff alleged that men treated her differently when she was promoted and that she feared revealing a pregnancy to her superior.

The jury on the case ruled in 2014 in favor of the plaintiff, awarding her $185 million in punitive damages as well as approximately $873,000 in back wages.

She alleges that the district manager told her to "suck it up," and she is filing a lawsuit against AutoZone for violating her civil rights.

[46] AutoZone came under fire from allegations that a district manager had told an employee to remove a flag displayed on the company's premises for the sake of improved diversity.

AutoZone denies that and claimed that it was the poor means by which the flag was put up, with duct tape and suction cups.
