Watch out for
- The FCC says you can legally block your number on outgoing calls. It isn't spoofing.
- The FCC requires carriers to offer per-call blocking, which is what *67 does, so you repeat it on each call.
- Carriers can also offer per-line blocking if they offer per-call unblocking as well. Ask your carrier what it provides.
- In 2025 the FCC asked for comment on how calls made with *67 should be treated. That is a proposal, not an adopted rule.
What stays out there
Hiding your number only controls what the person you call sees. Anything that was public earlier may already sit on people-search sites and data brokers that scraped it, and a setting on one platform doesn't change those copies.
Serus finds where your details are listed and removes them. It doesn't change your your phone carrier settings for you, so do the steps above yourself first.
If your number is already in caller-ID databases or on people-search sites, hiding it on calls doesn't touch those listings.
