419 Area Code: Toledo, Ohio

Northwestern Ohio is served by the 419 area code, with Toledo as the primary city. Toledo sits at the western end of Lake Erie at the mouth of the Maumee River, on a stretch of the lake that has long anchored a working port and a substantial industrial history — the city was a major center of glass manufacturing through the twentieth century, and the surrounding region's automotive and refining base has shaped the local economy alongside the lakefront commerce. The 419 footprint extends through Findlay, Mansfield, Lima, Sandusky, and the surrounding cluster of northwestern Ohio cities and counties.

In records the directory has compiled for 419 numbers, other Ohio cities — Akron, Cincinnati, Cleveland, and Columbus — recur frequently. None of those are inside the 419 footprint. The pattern reflects standard public-record dynamics, with phone numbers porting across Ohio and addresses linked across multiple cities. The directory currently documents 618 distinct prefixes within 419 in detail, a working subset of the prefix population the code carries.

Toledo's home values come in dramatically below the US median, with median household income running well below the national figure. The city's median age sits a few years under the US reading, and population places Toledo among the larger cities in Ohio — substantial enough to anchor a regional economy organized around the port, the automotive supplier base, healthcare, and the surrounding mix of mid-sized cities and farming counties of northwestern Ohio.
