Expanding protections against unwanted telephone calls and text messages for cellular users.

HB 1103 expands Washington state protections against unwanted phone calls and text messages by requiring businesses to identify themselves within 30 seconds, stop calls immediately when requested, and remove contact information from their lists for at least one year upon opt-out. It prohibits calls before 8 a.m. or after 8 p.m., enforces compliance with the federal Do Not Call Registry, and bans calls violating federal law. The bill directly affects cellular users (who gain stronger opt-out rights) and businesses making telephone solicitations (who face $1,000 fines per violation for noncompliance). Key mechanisms include mandatory call termination within 10 seconds of a request to stop, prohibition on selling contact data, and requirements for telecom companies to notify residential customers about these rules.
