🇺🇸 900 numbers
900 is the North American code for premium-rate services: the caller pays far more than a normal call, and the charge goes to the number's owner. You will rarely be called from one, but you may be asked to call one — that is the moment to stop and check.

The premium-rate trap
Scams rarely call from 900 numbers; they get you to call one. A prize notice, a "missed delivery" message or a voicemail from a "relative" asking you to ring a 900 number back is the pattern to watch for.
About 900 numbers
A 900 call is billed to the caller's phone bill at a rate the number's owner sets. Legitimate uses (paid hotlines, televoting) still exist but are rare; most people who end up dialing one were asked to in a message, a voicemail or a prize notice.
If you are asked to call a 900 number to claim, confirm or unlock something, treat it as a red flag and check the number first.

How much does a 900 call cost?
The owner of the number sets the price, per minute or per call, and it is added to your phone bill. The rate must be disclosed before the charge starts.
