# Block a Number
Receiving unwelcome calls and/or messages? With call blocking, you can take back control of who contacts your lines (including fax numbers!) and how you would like to be notified.
## Block a number
Numbers can be blocked for both shared lines, and individual users. Let's take a look at each.
### **Individual User**
To block a number for your own account (not a Shared Line), head to the Dialpad app.
1. Select the interaction/contact you'd like to block
2. Open the conversation thread view
3. Select **Block**

The pop-up window provides three options:
| **Block and Send to Voicemail** | Callers will be sent directly to voicemail. Conversations with this contact will appear in your inbox and in your **Recents**. |
| --- | --- |
| **Mark as Spam** | Callers will be sent directly to voicemail, and calls and messages will be sent to your **Spam** folder. |
| **Block All Communications** | Your number will appear out of service when the contact tries to call. |
Contacts can also be blocked directly from the Contact's profile. Select the contact, click **Edit Contact** and select **Block.**
Once selected, your preferences will take effect immediately.
Note
Blocked numbers will still appear in search results.
### **Shared line — Admin**
To block or update a Shared Line's number, you must have **Admin** permissions.
From the **Dialpad app**:
1. Navigate to the **Shared Line's Inbox**
2. Identify the number you'd like to block
3. Select the number/contact to open the conversation thread view
4. Select **Block or Mark Spam** from the header, OR, select **Block Contac**t from the contact profile
The pop-up window provides two options:
| **Block and Send to Voicemail** | Callers will be sent directly to voicemail. - Conversations with this contact will appear in your**Inbox** and in your **Recents**. |
| --- | --- |
| **Block All Communications** | Your number will appear out of service when the contact tries to call. |

Once selected, your preferences will take effect immediately, but *only for that Shared Line.*
Contacts can also be blocked directly from the Contact's profile. Select the contact, click **Edit Contact** and select **Block.**
## Manage blocked contacts & numbers
Things change, accidents happen, and blocked numbers can easily be unblocked.
To unblock a number from the Dialpad app:
1. Navigate to your **Contacts**
2. Select **Blocked**— here, you'll see a list of any contacts or numbers that are blocked.
3. Click on the contact name or phone number you'd like to block
4. Select **Unblock** from the banner at the top of the conversation thread, OR, select **Unblock** from the contact profile .png)
That's it! The number will immediately be removed from your spam list.

## Frequently Asked Questions
### If I block someone on my line, does it block it across the company?
No, it'll just block it for you. If you want it blocked across shared lines, reach out to your Admin to block that number.
### Can shortcodes/emergency numbers/special numbers be blocked?
No.
### Is there a way to review a list of all Office, Department, or Contact Center's blocked numbers?
Not at this time.
### **What happens if I delete a blocked contact and then re-interact with them?**
The contact is recreated and is unblocked.
### If there are multiple contacts with the same number, and I block that number, will Dialpad display all contacts as blocked?
No. If you block a contact and then there's another contact with that same number, we will not show that the second contact was blocked. However, calls from that number will still be blocked.
### If I block a number, does it block faxes too?
Yes.
### If I block a number, will it block SMS as well?
Yes.
### Will I be charged if a blocked or spam number sends a message?
No charge applies if the number is blocked, because messages from blocked numbers don’t come through. However, if a number is marked as spam and routed to voicemail, the voicemail is delivered to your Dialpad inbox and uses credits, which results in a charge.
