If you need to prevent a phone number from calling in to your organization, Invoca lets you block it.

Blocking a number

  2. Find the network, Advertiser, or Publisher you want to apply this to, then under the Tools section, click Blocked Numbers.

    • Example: to block all numbers starting with “1-805-452,” enter country code “1” and phone number “805452.”
  4. Read the warning that appears, then click Save.
