Consumers can register for free, but telemarketers have to pay for access to the registry.
The law takes effect today, regulated by the state Consumer Protection Board, but don't expect immediate relief. Telemarketers have 30 days to stop calling people on the first list. Under state law, the list must be updated at least quarterly. So if you haven't pre-registered, your number can be added on the next list, which will be issued July 1. Telemarketers then have 30 days from that date to stop making non-exempt calls.
