The United States of America's telephone numbering design and structure constitute a North American Numbering Plan (NANP) component. This plan divides the country and various territories into geographical territories. Each part is assigned a three-digit area code that precedes the seven-digit telephone number. One such code is area code 657, and this article explores its significant information and associated aspects.

Area Code 657: Location

Area code 657 belongs to California and covers portions of Los Angeles and Orange County. It was instituted as an overlay to the 714 area code on September 23, 2008, when the available phone numbers in 714 were becoming exhausted. As an overlay, the residents and businesses, who already had the 714 phone number, maintained it, but all new phones issued were assigned area code 657.

Zip Codes

Area code 657 extends to several zip codes to cover cities such as Anaheim, Santa Ana, Garden Grove, Buena Park, and Huntington Beach. Some of these zip codes include 92801, 92802, 92804 in Anaheim; 92701, 92703, 92704 in Santa Ana; 92840, 92841, 92844 in Garden Grove; and 90620, 90621 in Buena Park.

Since it overlaps with the 714 area code, there are instances where two phones from the same city might have different area codes. For example, older phone lines in Santa Ana will maintain the 714 area code, whereas newer phone lines will bear the 657 area code, regardless of the zip code.


The population under area code 657 is diverse, spanning several cities. As of the data provided in the 2019 census reports, the people of this region was approximately 3.2 million residents, making it one of the most densely populated areas in California.

Significant cities, like Anaheim, house a population of over 350,000, while Santa Ana has around 330,000 residents. On the lower end, Huntington Beach has a population of close to 200,000. These figures might have experienced a slight change given the natural progressions of birth, death, and migration rates.

Relevant Information

Almost 60% of the residents in the 657 area code speak English, while a considerable proportion of the population also communicates in other languages, especially Spanish. This can be attributed to the rich diversity in California.

The local time in area 657 follows the Pacific Time Zone (PST/PDT). It operates under Pacific Standard Time (UTC-8) throughout the standard year and then switches to Pacific Daylight Time (UTC-7) during daylight savings.
