How to Contact DTSC
If you can't find the answer to your question on our Web site, or want to walk through regulatory requirements with a live person, our Regulatory Assistance Officers will be able to help. Call (800) 72TOXIC - that's (800) 728-6942. From outside California, call (916) 324-2439. Don't be put off by getting voice mail - you will hear from one of them either the same day or the next business day.
At DTSC, we are committed to being honest, open, responsive, and direct with the public. The links below direct you to various means of giving us your feedback.
