XEAZ received its concession on April 17, 1948. The station was originally owned by Fernando Sánchez Mayans.[2] It may have signed on as early as December 20, 1947, as a border blaster where programs were recorded at studios in San Diego before being broadcast from the Tijuana transmitter.[3] Its Tijuana studios were in a building that burned in a December 1951 fire, which claimed 41 lives.[4]
In the 1980s, the station's Notitrece newscasts were the highest-rated in Tijuana.[5] During the January 1993 Tijuana floods, the station opened its microphones to provide non-stop coverage and air demands for aid and food in the wake of the devastation caused. Employees pulled up to 18-hour shifts. The non-stop coverage from XEAZ, one of the city's smallest stations, led to praise from El Universal's Tijuana correspondent and an article in the San Diego Union-Tribune.[6]
Radiodifusoras Capital acquired XEAZ in 2005[2] and sold the station to Grupo Radiodigital Siglo XXI, which soon merged with Grupo Radio México.
In 2015, XEAZ and 24 other radio stations were folded into Grupo Radio Centro, a business owned by the same family as GRM. GRC leased and then sold the station to PSN in 2021.
