What does 888-382-1222 do?
The National Do Not Call Registry is run by the FTC and is free. You can register at DoNotCall.gov or by calling 1-888-382-1222 — TTY 1-866-290-4236 — but you must call from the phone number you want to register. Cell phone numbers are accepted and treated exactly the same as landlines.
Registration never expires. The FTC removes a number only if it is disconnected and reassigned, or if you ask for it to be removed. Your number appears on the registry the next day, but lawful telemarketers are given up to 31 days to update their lists, so calls may continue for a month.
Register online and you get an email per number with a link you must click within 72 hours, and you can do at most three numbers per session. By phone, you have to call from each number separately.
Important: The registry only binds legitimate companies. It does nothing about scam robocalls, and anyone offering to register you for a fee is running a scam — it is free.
