History & Background of Area Code 201
Area code 201 was introduced in 1947 as one of the original 86 NANP area codes and became the first area code assigned in the United States. It originally covered the entire state of New Jersey before a series of geographic splits gradually reduced its service area to northeastern New Jersey, where it now serves communities in Bergen and Hudson counties.
- 1947: Area code 201 was introduced as one of the original 86 U.S. area codes and was assigned to the entire state of New Jersey, making it the first area code in the United States.
- Rotary Dial Design: The 201 code was relatively efficient for rotary dialing because its digits required fewer pulses than many other area codes. It required 13 pulses to dial, compared with an average of 14.1 for area codes created around the same period.
- 1951: Englewood, New Jersey, within the 201 service area, was the origin of the first direct-dialed long-distance telephone call in the United States, placed to Alameda, California.
- 1958: Area code 609 was introduced as New Jersey's first major geographic split from the original 201 territory, reducing 201's statewide coverage.
- 1997: Further geographic changes reduced the 201 service area, with area code 973 taking over parts of northern New Jersey.
- 2001: Area code 551 was introduced as an overlay to 201, allowing new telephone numbers to be assigned within the same geographic region without requiring existing customers to change their numbers.
- Current Coverage: Area code 201 now primarily serves northeastern New Jersey, including Bergen and Hudson counties and communities such as Jersey City, Hoboken, Hackensack, and Bayonne.
Why Local Numbers Build Trust
A local 201 number gives customers geographic context when they receive a call from a business serving northeastern New Jersey.
- Improve Customer Response Rates: A recognizable 201 number can make an incoming call appear relevant to customers in Jersey City, Hoboken, Hackensack, and surrounding communities. A local area code is only one factor in whether someone answers and does not guarantee a higher pickup rate.
- Build Local Credibility: A 201 number can reinforce a business's connection to northeastern New Jersey. This is particularly relevant for businesses whose customers are concentrated in Bergen and Hudson counties.
- Support Consistent Local Search Information: Using the same local business phone number across a website, business profiles, and directories helps maintain consistent contact information. The 201 area code itself should not be presented as a guaranteed local SEO ranking factor.
- Establish Familiarity Before the Call: A 201 caller ID immediately gives customers geographic context. Pairing the number with an identifiable business name and accurate caller information can make the call easier to recognize.
