358 Area Code: Is It Real? Lakeland FL (863) & Finland (+358) Guide
Area code 358 is unassigned in the US. This guide covers the 863 area code serving Lakeland/Central Florida and +358 Finland country code.
If you're searching for the 358 area code, you've likely encountered one of three things: the 863 area code for inland Central Florida (Lakeland, Winter Haven, Sebring), the international country code +358 for Finland, or a spoofed spam call. Area code 358 itself is not assigned in the North American Numbering Plan.
This guide covers the 863 area code serving Central Florida — home to Publix headquarters, the world's largest collection of Frank Lloyd Wright buildings, North America's oldest racetrack, and one of America's fastest-growing counties — and clarifies the +358 Finland country code.
Area Code 358 Is Not in Service
Area code 358 is unassigned. If you received a call displaying 358, it was almost certainly spoofed, meant to be 863 (Lakeland/Central FL), or an international call from Finland (+358).
