Overview

The Blocked Numbers feature allows you to prevent specific phone numbers from reaching your Bland inbound lines. A block rule applies in one of two ways:
  • Individually: Block a number for a specific inbound number only
  • Globally: Block a number across all your inbound numbers

​
Individual Number Block Rules

You manage block rules for a single inbound number from that number’s configuration in Dispatch.
  1. Use the selector at the top of the sidebar to switch to All agents
  2. Under Dispatch, open Phone numbers
  3. Press Configure on the number’s row
  4. Open Blocked numbers, under Call screening
Here, you can configure block rules that apply only to the selected number.

​
Global Number Block Rules

A global block rule rejects a phone number regardless of which of your inbound numbers it calls. To create one, send is_global: true to the Create Block Rules endpoint.

​
Block Rule Fields

Each block rule in the table includes the following columns:
  • Blocked Number: The E.164 formatted phone number that is blocked
  • Type: global or specific, depending on whether it applies to all numbers or just one
  • Reason: Optional text indicating why this number was blocked
  • Status: Indicates if the rule is currently active; can be toggled without deleting
  • Created: Date the rule was originally added
  • Actions: Options to edit or delete the rule

​
Adding Block Rules

When adding new block rules, you can paste or enter numbers in bulk using:
  • Comma-separated values (CSV)
  • Space-separated values
  • New line-separated values
You may also optionally include a reason for blocking the number(s). Add Block Rules Form

​
Editing Block Rules

Block rules can be edited after creation to:
  • Update the reason
  • Toggle status active or inactive
Note: Once a block rule is created, the phone number itself becomes immutable. You cannot modify or replace it. Only the reason and status can be changed.
