Geographic Coverage

The 985 area code covers southeastern Louisiana outside the New Orleans core, including the St. Tammany Parish Northshore cities of Slidell, Mandeville, and Covington on the north side of Lake Pontchartrain, Hammond and Bogalusa to the north, and the bayou region of Houma, Thibodaux, and Morgan City to the southwest. It surrounds the 504 area code on multiple sides.

Time Zone

The 985 area code observes Central Time (CT). Clocks follow Central Standard Time (UTC−6) in winter and shift to Central Daylight Time (UTC−5) from mid-March through early November. All of Louisiana is on Central Time. From the West Coast, this region is two hours ahead of Pacific Time, so a 9:00 AM call in California reaches a 985 number at 11:00 AM local time.

Tip: Business hours across the 985 region generally run 9:00 AM to 5:00 PM Central Time, Monday through Friday.

How to Dial a 985 Number

Area code 985 is not part of an overlay, so it has traditionally allowed 7-digit local dialing. However, 10-digit dialing is now the recommended nationwide standard, and dialing the full 10-digit number (985 + the line number) always works reliably. For international callers, dial your country’s exit code, then +1 (the North American country code), then 985, followed by the seven-digit local number.

  2. Hang up and verify by calling the organization back using an official number from its website.

History and Economy of the 985 Region

n

Area code 985 was created in 2001, split from 504, to serve the Northshore and the bayou parishes of southeastern Louisiana. The regional economy has two distinct centers. The St. Tammany Northshore – Slidell, Mandeville, and Covington – has grown rapidly as a suburban bedroom community for New Orleans commuters, connected by the Lake Pontchartrain Causeway. To the southwest, the Houma-Thibodaux area is a hub for the offshore oil-and-gas services industry, shipbuilding, and commercial seafood, especially shrimp, while Hammond is home to Southeastern Louisiana University and Morgan City anchors the lower Atchafalaya energy and fishing economy.
