text: what are the addresses for allstate auto claims in california?   well that would depend on the type of claim you have, and where the file is being handled. your best bet is to have  claim number handy, and contact 866-622-7296, m-f 7:00am to 7:45 pm, and sat. 08:00am to 4:30 pm. but as a rule allstate is going to start having all is mail sent to a centralized mailing point.
