# Number not available for Flow
If you're unable to select your Virtual Mobile Number within a flow there are some simple checks you can do within [the Numbers tab](https://dashboard.messagebird.com/en/numbers) of the dashboard before reaching out to support!
#### **Check if the number has the capabilities you are trying to set up a flow with.**
Simply look at what icons are black to verify the capabilities of this number. A Voice number cannot be used for an SMS flow and vice versa.
#### **Check if the number is already assigned to a flow.**
If there is a flow name next to the number, it is already used for a flow. You can create one flow per capability, so, if you have a Voice and SMS capable number you can add both an SMS flow and a Voice flow to the number.
#### **Check if the number is assigned to a subaccount.**
If there is a subaccount name next to the number you cannot create a flow with that number in any other account. Do note that this can only be checked within the main account; if you are in a subaccount you will only see the numbers that have been assigned to the subaccount you are logged in to.
If you find that you should be able to add the number to your flow but are not able to, please reach out to our Support team via [this page](https://www.messagebird.com/contact) with the following information:
* The number you're trying to add to the flow
* The use case you are trying to achieve
* Any error you may have received
We'll be more than happy to help!

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.bird.com/connectivity-platform/troubleshoot-a-flow/number-not-available-for-flow.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
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.
