California 925 Area Code

The NANP (the North American Numbering Plan) administration performs a wide range of activities to maintain the area codes and telephone numbers well organized. Among their duties, we can find the assistance to potential applicants by providing information about numbering resources, the process of applications for resource assignments in a timely manner, the assignment or denying of numbering resources in a consistent manner and the possibility of giving advice to regulators and the industry about potential exhaust of the resources. These amazing responsibilities are all connected with area codes and numbers. If you are wondering why it is so important to have an area code list ready to be used properly, the answer is that it is essential to be able to get communication fast and properly.



There are lots of area codes in the California State. One of them is the 925 area code. This area code was created in 1988 and it includes the residents of the east portion of Oakland area, who were served by the 510 area code before the 925 area code was prepared. The 925 area code also includes other parts of the East Bay area. This means that there are two main counties included in this area code: Alameda County and Contra Costa County. The number “925” was created by taking the original area code, 415, and then adding 510, the area code created in 1991.



Regarding the cities which are included in the 925 area code, we can mention Dublin, Sunol, Pleasanton Livermore and many others within Alameda County.



When a new area code is introduced in the list, there are several things to remember. It is important to notify friends, relatives and business clients about the change. Naturally, it is vital to change stationary, business cards and any type of advertising which contain the old area code. Once you have checked all these items, you will be sure that people are able to contact you correctly. Nowadays, the Internet has added the opportunity to find much information about our area codes. For example, if you type "925 area code" in your favorite browser, you will find all the geographical areas included in this area code, maps, reported phone numbers in the 925 area code, etc. Therefore, there is no excuse if we dial an area code wrongly.



The 925 area code was created to give the possibility of having new phone numbers to more people. So, this incredible demand could only be fulfilled by designing a new area code. California is growing continuously. For this reason, it is essential to reorganize its area codes from time to time. The US has had an explosion of new area codes since ten years ago. For this reason, the NANP allowed the recreation of new area codes in 1995. Since then, millions of telephone numbers were changed from one area code to a new area code (area codes were spitted).



People who live in the area which is part of the 925 area code could think that changing of area code was a new problem but after some months they understood that it was created to give them a high quality phone service.
