Byram is officially Mississippi's 297th municipality, and its interim Board of Aldermen will be sworn in Monday at the Capitol.
The first jobs for board members will be figuring out how many of the area's 7,000 residents live within city limits, setting a budget and taxes, and writing ordinances to cover daily operations.
The secretary of state issued a city charter for Byram earlier this month, after the state Supreme Court refused to reconsider its unanimous ruling that the area could incorporate.
Jackson, which has long sought to annex the area, had asked for a rehearing.
