# Your caller numbers

> The numbers your campaigns can call from, how to ask for one, how to pick it in the wizard, and why you may not need one.

A caller number is what shows on the phone of the person being called. DeepBlocker owns a pool of UK and US numbers and allocates some of them to your workspace. You then pick one in the campaign wizard. You cannot type in a number of your own; only allocated numbers can be used.

## Why you may not need one

Every campaign can run without a number of your own. When your workspace has none allocated, the wizard says: "No numbers allocated to your workspace yet, so calls use the platform default." The call still goes out, from a DeepBlocker number.

Ask for numbers when:

* You want the same number to show on every call in a programme, so staff who report it can be matched to the test.
* You need a UK number for UK staff or a US number for US staff. A UK number dials on the UK system, a US number on the US system.
* You run a call-back trap and want a number that stays yours for the campaign.

## Ask for a number

**1. Email us**

Write to [hello@deepblocker.ai](mailto:hello@deepblocker.ai) with your workspace name, the region you need (United Kingdom or United States) and how many numbers.

**2. We allocate it**

We assign numbers from the pool to your workspace. Nothing is installed and nothing changes on your side.

**3. Pick it in the wizard**

The numbers appear in every new campaign under **The number to call from**.

## Pick a number in the wizard

On the **From where and when** step, the first block is **The number to call from**. Its help text reads: "Pick the number this campaign calls from. A UK number dials on the UK system, a US number on the US system."

| What you see | What it means |
| - | - |
| A card per number, with **United Kingdom** or **United States** under it | The numbers allocated to your workspace |
| A highlighted card | The number this campaign calls from. Click it again to clear the choice |
| **Loading phone numbers...** | The list is being fetched |
| **Couldn't load phone numbers** | The fetch failed. Click the retry link, or reload the page |
| "No numbers allocated to your workspace yet, so calls use the platform default." | None allocated. The campaign still launches |

The choice is per campaign. A different campaign can call from a different number.

## What a number cannot do

* It does not change where your data is kept. Region settings are separate; write to [contact@deepblocker.ai](mailto:contact@deepblocker.ai) if you need UK handling.
* It does not change the voice, the scenario or the schedule.
* It does not make a campaign launch when consent or authorisation is missing. See [Authorise and launch](https://docs.deepblocker.ai/vishing/campaigns/authorise.md).

## Problems

> [accordion] I see no numbers in the wizard
>
> None are allocated to your workspace yet. Email [hello@deepblocker.ai](mailto:hello@deepblocker.ai). Until then calls use the platform default number.

> [accordion] A number I was given is not in the list
>
> Numbers are allocated per workspace. If you have more than one workspace, check which one you are signed into. Then write to [contact@deepblocker.ai](mailto:contact@deepblocker.ai) with the number and the workspace name.

> [accordion] Staff say the call came from a number I did not pick
>
> The campaign had no number chosen, so it used the platform default. Open the campaign, pick a number under **The number to call from**, and save a new version.
