# Caller Verification and Blocked Callers in the Scale to Win Dialer
The **Caller Verification** and **Blocked Callers** features work together to empower dialer admins with increased campaign security. The former creates hurdles for troll callers, and the latter enables admins to block them from continuing to make calls.
### **Enable Caller Verification**
This feature can be enabled from the Settings page by turning on the toggle labeled “Require phone verification for callers.” Once enabled, callers in future dialer campaigns must send an SMS verification code to their cell phone, and then enter the code to make calls. Callers must have access to a cell phone, as landlines cannot receive the SMS verification code.
**Note:** In order to use this feature, you must enable the Messaging feature, which allows you to send texts from your dialer account. This feature can be requested at the bottom of the Settings page. You can read more about enabling this [here](https://support.scaletowin.com/question-type-text-message?hsLang=en).
#### **Caller User Flow:**
1. When Caller Verification is enabled, callers attempting to dial will be required to enter their mobile number and send themselves a code.
2. Callers will need to enter the code they receive before they can start dialing in the campaign.
**Note:** Callers can save their information for 2 weeks, so they don’t need to verify every time they call. Admins can still block callers identified as trolls.
### **Blocked Callers**
A new Blocked Callers page is accessible to Admins on the left side panel. From this page, you will add the phone numbers of callers that should not be granted access to your dialer campaigns. Admins can add notes to the numbers they block to keep strong, internal documentation.
Admins can also review blocked numbers, attached notes, the name of the admin that submitted the block, and the date the block was submitted.
In addition, Admins can use the trashcan button to unblock a caller, allowing them access to dialer campaigns again.
**Note:** Blocked Callers only works on campaigns that have Caller Verification enabled.
