Area code 458 is an overlay for 541 in Oregon, covering most of the state outside the Portland metro, including Eugene, Bend, and Medford. Introduced in 2010, 458 was implemented to expand number availability while preserving existing 541 numbers. The overlay made ten-digit dialing mandatory across the region. This area code serves a blend of college towns, forested landscapes, and growing rural communities. It is increasingly used for mobile phones, VoIP, and newer businesses. 458 supports continued growth across Oregon’s diverse geographic and economic landscape.
