History
Startup was homesteaded by F.M. Sparling in the 1880s. He left the area in 1889 after getting married and sold his property to William Wait, who filed a plat for the town of Wallace on March 22, 1890. The town's name caused confusion with mail being mistakenly sent to Wallace, Idaho, and in 1901 the name was changed to Startup to honor George G. Startup, manager of the Wallace Lumber Company.
The Startup post office was established in 1900.
The settlement was mistakenly excluded from receiving mailed questionnaires for the 2000 census due to a post office error.
