All 200-Series Area Codes
Browse every active area code in the 200–299 range across the United States.
The 200-series is the foundational block of US area codes — the original tier assigned when the North American Numbering Plan launched in 1947, anchoring some of the country's largest and most recognizable metros. Codes in this range serve a striking mix of geographies: 212 in New York City, 213 in Los Angeles, 214 in Dallas, 215 in Philadelphia, and 206 in Seattle all sit alongside smaller-metro codes like 207 in Portland, Maine and 218 in Duluth, Minnesota.
The range stretches from the Pacific Northwest down through the Gulf Coast and back up to New England, with later additions filling in around the original assignments as overlay codes for fast-growing regions. Several states appear more than once across the group — Pennsylvania alone holds 215, 223, 267, and 272, reflecting decades of demand pressure on its major metros.
