What is the Country Code for California, USA?

by Aurora

When dialing to California, USA, understanding the country code is crucial. The country code for California is +1. The United States, including California, uses the country code +1, which is a part of the North American Numbering Plan (NANP). This article will explore the different aspects of dialing to California from both domestic and international locations.

The Structure of a California Phone Number

To better understand how to dial to California, we need to break down the full structure of a phone number in California.

A typical phone number in California is written in this format:

+1 (XXX) XXX-XXXX.

  • +1 – This is the country code for the United States, which includes California.
  • (XXX) – This is the area code for California. There are many area codes in California depending on the city or region.
  • XXX-XXXX – This is the local phone number.

The country code +1 is consistent across the United States, including all 50 states and several territories like Puerto Rico, Guam, and the U.S. Virgin Islands.

Why California Has the Country Code +1

California, like the rest of the United States, uses the country code +1 as a part of the North American Numbering Plan (NANP). The NANP is a system that was established in 1947 by AT&T to streamline telephone numbers and eliminate confusion in long-distance calling. The +1 country code represents the entire North American continent, which includes the U.S., Canada, and several other territories.

Although the +1 country code is used for the entire United States, each state, including California, has its own unique area codes for specific regions or cities.

How to Dial to California from Outside the USA

If you are calling California from outside the United States, follow these steps:

  • Dial the international access code – Depending on the country you are calling from, this access code may vary. For example, it’s 00 in many countries, like in the European Union, or 011 in Canada.
  • Dial +1 – This is the country code for the United States.
  • Dial the area code for California – California has many area codes, so make sure you are dialing the correct one based on the region you are trying to reach.
  • Dial the local phone number – After the area code, dial the rest of the phone number.

For example, if you’re calling a number in Los Angeles from the UK, you would dial:

00 + 1 + 213 + XXX-XXXX.

California Area Codes

As one of the most populous states in the U.S., California has a vast number of area codes. These area codes are assigned to specific cities, regions, and counties across the state.

Here are some examples of area codes in California:

  • 213 – Los Angeles
  • 415 – San Francisco
  • 818 – San Fernando Valley
  • 909 – Inland Empire
  • 510 – Oakland
  • 562 – Long Beach
  • 619 – San Diego

There are many more area codes in California, especially in densely populated cities like Los Angeles, San Francisco, and San Diego. Each area code is specific to a region, and in some cases, multiple area codes may cover a single metropolitan area due to population growth and demand for phone numbers.

California Zip Codes and Their Role

Zip codes, although not directly related to phone dialing, play a critical role in identifying specific regions within California. While the country code +1 is used for phone calls, zip codes are used for mail delivery and location identification.

California has thousands of zip codes, and they help route mail and packages accurately and efficiently. Some major cities in California, such as Los Angeles, San Francisco, and San Diego, have multiple zip codes based on neighborhoods and districts.

For example:

  • 90001 – Los Angeles (South Central)
  • 94102 – San Francisco (Civic Center)
  • 92101 – San Diego (Downtown)

These zip codes can be used for addressing packages, locating places within California, or identifying specific areas for services like emergency response or local events.

International Dialing: Key Considerations

When dialing to California from abroad, keep in mind that the calling process is not the same as a domestic call.

Here are some key considerations when making international calls:

  • International access code – Each country has a specific international dialing code. For example, the UK uses 00, while Canada uses 011.
  • Time zone differences – California is in the Pacific Time Zone (PT), so be mindful of the time when making international calls. It’s a good idea to check the local time in California before dialing.
  • Correct area code – Make sure to check and use the correct area code for the city or region you are calling in California.
  • Calling plans – Some international service providers offer discounted rates for calling the U.S. Be sure to check with your provider for the best plan.

Dialing California From Other U.S. States

If you are calling California from another state in the U.S., you will also use the +1 country code, but you do not need to dial the international access code. Simply dial the area code and local number.

For example:

  • From New York to Los Angeles: (213) XXX-XXXX
  • From Texas to San Francisco: (415) XXX-XXXX

This is because +1 is the country code for the entire United States, so domestic calls don’t require the international dialing code.

Dialing California from Canada

Canada also shares the +1 country code with the U.S. and other North American countries.

To dial California from Canada, follow these steps:

  • Dial 1 (country code for the U.S.)
  • Dial the area code for California.
  • Dial the local phone number.

For example, calling Los Angeles from Toronto would look like:

1 + 213 + XXX-XXXX.

Conclusion

In conclusion, California uses the +1 country code as part of the North American Numbering Plan (NANP), which is used for telephone calls to the U.S., Canada, and several other regions. When dialing to California, you need to dial the correct international access code, followed by +1, the area code specific to the region you’re calling, and the local phone number.

Understanding the country code for California is important for making international calls, and this knowledge can save you time and avoid mistakes when dialing. Whether you’re calling from outside the U.S. or within the country, knowing how to dial correctly ensures smooth communication.
