Sending a fax to California
- Upload a PDF, PNG or JPG, or write a cover page with your letterhead.
- Choose United States as the recipient’s country and type the 10-digit fax number, for example (213) 555-0123.
- Check the number and send. You get a time-stamped delivery receipt.
Each page sent to California uses 1 plan page from a US or Canadian number, and a fax that isn’t delivered doesn’t use any.

Healthcare and legal offices in California
Healthcare ›
Clinics, labs and pharmacies in California still exchange referrals, records requests and prior authorizations by fax. If your office handles protected health information, HIPAA applies wherever you are in the US. California also has its own medical privacy law, the Confidentiality of Medical Information Act (CMIA). FaxToFax stores faxes encrypted, records every view and download in an audit log, and deletes faxes on the schedule you set. A Business Associate Agreement is available on Business plans.
Legal ›
Law offices fax notices, signed documents and records requests when they need a sender, a time and a receipt. Lawyers in California must protect client confidences under the state’s rules of professional conduct. FaxToFax puts your letterhead on cover pages, keeps a delivery receipt with every fax, and limits who can open faxes with access roles.
FaxToFax provides tools that support compliance; each office remains responsible for its own obligations. The Trust Center lists the programs we currently meet.
