How do I update my phone numbers online?
Login to your Coast360 online service or mobile app. Select Menu > Profile > Contact Information > List a phone number for all three number fields (Repeating a number is acceptable) > Submit changes > Complete security code verification
Note: This update will require that you receive a security code at an existing contact number on file before submitting the update. We recommend to keep your previous number active for this purpose or verify with your provider if the code can be forwarded to your new number to complete the update.
