A Comprehensive Biography of the 201 Area Code

The 201 area code holds a unique and prestigious place in the history of American telephone numbering. It was one of the 86 original area codes created by AT&T and the Bell System in 1947 as part of the initial rollout of the North American Numbering Plan (NANP). * Birth Date: 1947 * Original Coverage: The entire state of New Jersey * Initial Split (1956): The first split occurred in 1956, creating the 609 area code for the southern half of New Jersey. This was the first of several splits that gradually reduced 201’s territory. * Key Splits: Subsequent splits introduced 908 (1990), 201/973 (1997), and 732 (1997), eventually confining 201 to the northeastern corner of the state. * Current Geographic Region: The region is now primarily defined by Bergen County and Hudson County. * Major Cities Served: Jersey City, Hoboken, Hackensack, Bayonne, Union City, Englewood, Teaneck, and Secaucus. * Overlay Code: 551 (Implemented in 2001). * Dialing Requirement: Mandatory 10-digit dialing (Area Code + 7-digit number) for all local calls due to the 551 overlay. * Time Zone: Eastern Time Zone (ET).

The Rise of the 551 Overlay and Mandatory 10-Digit Dialing

The most significant modern update to the 201 area code came in 2001 with the introduction of the 551 area code as an overlay. An overlay occurs when a new area code is assigned to the same geographic region as an existing one, rather than splitting the territory. This was necessary because the demand for new phone numbers—driven by the explosion of cell phones, fax machines, and second lines—was rapidly exhausting the available prefixes in the 201 sequence. The 551 overlay covers the exact same territory as 201, which includes all of Bergen and Hudson counties. The immediate and lasting consequence of this change was the mandate for 10-digit dialing for all local calls. Prior to the overlay, residents could dial just the seven-digit number for local calls within the 201 area. Since 2001, however, every call made within the 201/551 region, even next door, must include the area code. This practice ensures that residents with a 201 number and those with a 551 number can coexist seamlessly within the same Numbering Plan Area. There are currently no new splits or overlays planned for the 201/551 region, making this a stable configuration for the foreseeable future.
