# Number Management

Businesses can efficiently automate the management of their Truecaller business numbers using our comprehensive Number Management APIs. 

These APIs offer a robust set of features to streamline various tasks, including:

* Listing Verified Numbers: Register and display your business numbers as verified on the Truecaller platform.
* Delisting Numbers: Easily remove numbers that are no longer in use, ensuring accuracy and relevance.
* Retrieving Verified Number Information: Access detailed information about your verified numbers.
* Managing Feature Sets: Obtain Feature Set IDs to organise and control numbers within specific feature sets.

By leveraging these APIs, businesses can significantly simplify and automate their number ownership and management processes, ensuring that their Truecaller profiles are always accurate and up-to-date.

{% hint style="danger" %}
When you use our APIs to list or delist a number, these operations are asynchronous. This means they don't happen instantly; there's a processing period.

It's important to know that if you try to delist a number and then immediately list the *same number* while the delisting is still being processed (i.e., it hasn't been fully delisted or failed), your subsequent listing request for that number will be ignored. It won't be picked up for processing until the initial delisting action is complete.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.truecaller.com/truecaller-for-business/truecaller-for-business/verified-business-api-documentation/number-management.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
