Area code 341 is being added to the 510 area code region. As a result, a new calling procedure will be required.
Beginning June 22nd, all calls made to the 510 and 341 area codes must include 1 + area code + 7-digit telephone number.
What will you need to do to prepare?
Update any pre-programmed 7-digit phone numbers on your desk phone (call forwarding, auto dials, abbreviated dials), fax machines, modems, alarm monitoring or security systems as well as your mobile device contacts to include the area code. Also, remember to update any text or email alert services.
Calls to 911 will be unaffected.
Contact Telephone Services at [email protected] or x7997 with questions.
