419 Area Code – Toledo, Ohio: Location, Time Zone & History

Glass manufacturing has long defined the northwest Ohio region served by area code 419, and Toledo's nickname, "The Glass City," reflects that legacy directly, with companies like Libbey Glass and the Toledo Museum of Art's dedicated Glass Pavilion tracing back generations of local craftsmanship. Automotive manufacturing plays a major role too, including Jeep and Stellantis assembly operations, alongside healthcare, higher education, and logistics and distribution.

The code itself dates to the very beginning of the modern telephone numbering system: 419 was among the original 86 area codes established under the 1947 North American Numbering Plan, assigned to the northwest quadrant of Ohio centered on Toledo. It remained the sole code for the region for over five decades until January 1, 2002, when the all-services overlay 567 went into service to relieve exhausted central-office codes, bringing mandatory ten-digit local dialing to the area.

Beyond Toledo, the 419/567 numbering plan area serves Lima, Findlay, Mansfield, Bowling Green, and Sandusky. Lucas County, the region's core county and home to Toledo, recorded a population of 431,279 in the 2020 U.S. Census.
