If you have a 916 area code number, get ready to change your dialing habits and perhaps update your saved or programmed phone numbers.
Starting Feb. 10, when you call from a 916 number, you must include the area code of the number you’re dialing for the call to go through. Instead of dialing seven digits, you’ll dial 1 + ten.
For example, to reach UC Davis Health, you’ll dial 1-916-734-2011. Simply dialing 734-2011 won’t work anymore.
