Managing blocked numbers in the <var class="keyword">
<div style="display: inline;">
RingCentral
</div></var> apps and Admin Portal
===================================================================================================================================

You can block spam and other unwanted calls by adding phone numbers to your blocked list in the <var class="keyword">
<div style="display: inline;">
RingCentral
</div></var> apps and Admin Portal. When you block a number, you won't receive calls, faxes, or text messages from that number.

Note:

* You can block a full 10-digit number or a subset of digits from the start of a phone number. For example, an area code and prefix (204-555).
* Numbers blocked from your extension only apply to that extension.
* If [a number is blocked on the main company extension](https://support.ringcentral.com/article-v2/7251.html?brand=RC_US&product=RingEX&language=en_US&pills-nav=admin_portal#blocking-numbers-company ""), the block applies to every extension on the account.
* You can still call and send faxes to a blocked number, but you can't send text messages.
* People whose numbers you block aren't notified.
* You can't block a coworker's number.
