Founded as '''Xi'an Huilong Football Club''' () in October 2013, the club was based in Xi'an, Shaanxi, and had previously competed in various Shaanxi FA-sanctioned amateur leagues, competing as either Xi'an Huilong or
Shaanxi Huilong. In 2018, Xi'an Huilong competed in the
2018 CMCL. In 2019, Xi'an Huilong competed in the 2019 Sina Golden Futsal League, a
five-a-side football tournament. The club moved to
Binzhou, Shaanxi in March 2020, where they have used the name
Binzhou Huilong. On 29 March 2023, Shaanxi-based club
Shaanxi Chang'an Athletic was dissolved after failing to register for the
2023 China League One season. Subsequently, Athletic's
phoenix club was founded as Binzhou Huilong and was purchased by investor Zhang Wei, and a number of players and staff of the former Shaanxi Chang'an Athletic setup joined the club. The original Binzhou Huilong team that Shaanxi Chang'an Union took over then formed Xianyang Binzhou Huilong F.C., a new club that would still play in the
Shaanxi National Super League. In the 2023 Shaanxi National Super League season, Xianyang Binzhou Huilong finished fourth place. Binzhou Huilong was then admitted into the
2023 CMCL, the Chinese fourth-tier, from a recommended team berth given to the
Shaanxi FA by the
Chinese FA, officially under the name
Shaanxi Binzhou Huilong Football Club Everyday Chain Team in a sponsorship with the
Everyday Chain. Under manager
Huang Yong, who had most recently been a youth team executive at Chang'an Athletic, they topped their group, finishing first overall in
CMCL's Rizhao regional group, to qualify for the final round. Shaanxi Chang'an Union were drawn into group B of the
2023 CMCL final round, and were up against
Dalian Huayi first. Union drew the game 1–1, and three days later on 6 September 2023, it was announced that Huang Yong would no longer be the Shaanxi Chang'an Union manager. The following day, former Athletic manager
Óscar Céspedes was appointed as Union's new manager. Union then went on a two-game losing streak, an early stump for Céspedes and his players. On 17 September, after a narrow 1–0 home loss to
Guangzhou E-Power and clapping the 26,156 fans in attendance post-match, club captain
Ding Jie kneeled down to the Shaanxi fans in apology. On 14 October 2023, after all seven games in the 2023 CMCL final round group stage and four straight wins to adjust themselves back on track, Shaanxi Chang'an Union finished 4th in their group of 8, settling for play-offs. In the promotion play-offs, Shaanxi Chang'an Union defeated
Changchun Shenhua on penalties after a 1–1 draw at the
Weinan Sports Center Stadium, with Shaanxi goalkeeper
Li Chen making two saves in the shoot-out to book their place in the final. On 29 October 2023, Shaanxi went on to beat Guangzhou E-Power 2–1 away from home in the play-off final thanks to goals from
Ma Yangyang and
Pang Zhiquan, both former Athletic players, winning promotion to
China League Two. On 26 January 2024, the club rebranded its name to
Shaanxi Union Football Club. On 20 February of the same year, Shaanxi Union moved into the
Shaanxi Province Stadium, and would move once again to the
Xi'an International Football Center during mid-season. ==Club identity==
