The Teamsterz were announced as a new member of the
United Premier Soccer League (UPSL) on February 28, 2017. The team began play in the Northeast Conference's American Division during the
2018 Spring UPSL season. In its first home match on April 14, 2018, at Don Ahern Veterans Memorial Stadium, the Teamsterz overcame two one goal deficits and finished with a 2–2 draw to earn its first ever competitive point. The group went on to finish third in its division, clinching a postseason spot before falling in the semifinals of the American Division playoffs to
Junior Lone Star FC II. The following Spring, New Jersey finished second within the conference, now playing within a single table, but failed to make the
national playoffs. On February 26, 2020, the Teamsterz announced it had been accepted into the
National Independent Soccer Association (NISA), a professionally sanctioned division 3 league, with plans to begin professional play in Spring 2021, though this was later pushed back to Fall due to then on-going COVID-19 pandemic. The organization further stated that it would not be fielding a UPSL team in 2020. In 2020, team owners Sibrena and Alex Geraldino were featured on
Discovery Channel's series "I Quit," which followed entrepreneurs who quit their jobs in order to launch new businesses. The team announced that they were changing the spelling of the team name from Teamsters to Teamsterz. On 23rd August 2021, the Teamsterz announce that they would join
NISA newly born amateur league, the
NISA Nation as founding member for the
2021 Fall season.
