The 945 area code has not undergone significant changes or updates recently. Since its creation in 1997, it has remained an overlay for the 415 area code, and no changes to its boundaries or regulations have been made.

However, with the increasing use of mobile phones and internet-based communication platforms, the demand for telephone numbers has decreased in recent years. As a result, the North American Numbering Plan Administrator (NANPA) has implemented a plan to introduce a new area code (820) to the 415/945 area code region. This will be a “geographic split” where the new area code will be assigned to a specific area within the existing 415/945 region, while the old 415/945 area code will remain in use for the rest of the region. This plan is on hold as the demand for numbers in the 415/945 area code has not reached a critical level.
