While you might see “1 510” listed before a phone number, it’s not actually a country code. It’s a specific area code within the North American Numbering Plan (NANP) that serves a particular region.
1 510 country code
Here’s what you need to know about the 1 510 code:
-
Location
- The 1 510 area code covers parts of the East Bay in California, including Oakland, Berkeley, and surrounding areas in Alameda and Contra Costa counties.
-
Sharing the Load
- Due to the growing population, a secondary area code, 341, was introduced as an overlay to serve the same region. So, you might see either 1 510 or 341 before a local phone number in this area.
-
Not a Country Code
- Country codes are used for international dialing. They identify a specific country within the international telecommunication numbering plan. The first digit of a country code is always a “1” for North American countries, but the following digits designate the specific nation. For example, the US country code is 1, followed by the area code and local number.
So, how do you dial a number with the 1 510 area code
If you’re calling from within the United States, you simply need to dial the 10-digit phone number, including the area code. But if you’re calling from outside the US, you’ll need to dial the exit code for your country, followed by the country code for the US (which is 1), and then the 10-digit phone number (including the area code).
Hopefully, this clarifies the difference between a country code and an area code. While 1 510 might appear before a phone number, it designates a specific region within California, not a separate country.
