A New Chapter: The Birth of the 840 Area Code

The 840 area code is a relatively young member of the North American Numbering Plan (NANP), the system that allocates area codes across North America. It was created on February 23rd, 2021, to address the growing demand for phone numbers in a specific region.

Where Does the 840 Area Code Ring?

The 840 area code is an overlay area code. This means it geographically overlaps with an existing area code, serving the same territory. In the case of the 840 area code, it overlays the well-established:

909 Area Code: Introduced in 1992, the 909 area code has served the far eastern portion of Los Angeles County and southwestern San Bernardino County in California.
The introduction of the 840 area code ensured a continued supply of phone numbers for residents and businesses within the designated coverage area, which primarily encompasses:

San Bernardino County: This county boasts diverse landscapes, ranging from mountains and deserts to urban centers. Major cities within San Bernardino County served by the 840 area code include Chino, Chino Hills, Colton, and Fontana.
Los Angeles County (Eastern Portion): The eastern portion of Los Angeles County served by the 840 area code includes suburbs and communities like Claremont, Glendora, La Puente, and Walnut.
A Thriving Region: The region served by the 840 area code is known for its dynamic economy, cultural attractions, and proximity to major metropolitan centers like Los Angeles and San Diego.

How Does the 840 Area Code Work?

The implementation of the 840 area code did not require existing phone numbers with the 909 area code to change. Landlines and mobile phones within the designated area could be assigned phone numbers with either the 909 or 840 area code. This ensured a smooth transition and minimized disruption for residents and businesses.

When making a call within the coverage area, you typically don’t need to dial the area code as long as you’re calling a number with the same area code (840 or 909). However, if you’re calling from outside the area or dialing a number with a different area code, you must include the appropriate area code (840 or 909) before the phone number.

The Impact of the 840 Area Code

The introduction of the 840 area code has had a significant impact on the telecommunications landscape of the region. Here’s a closer look at some key aspects:

Accommodating Growth: The creation of the 840 area code ensured a sufficient supply of phone numbers to cater to the growing population and increasing demand for phone services in the region.
Convenience for Newcomers: New residents and businesses moving to the area can now obtain phone numbers without facing a shortage of available options.
Potential Confusion: The presence of two area codes for the same region might cause some initial confusion, particularly for those unfamiliar with the overlay system. However, with time and proper awareness, this confusion should diminish.
