# Add, Edit, and Remove Extensions

User extensions not only allow your internal team to quickly dial out to each other but can also be used to route callers to your team quickly via the [dial-by extension directory](/v1/docs/dial-by-name-or-extension-directory) on your Main Line, Department, or Contact Center.

Let's take a closer look at extension dialing.

> [!NOTE]
> Who can use this
> 
> Extension dialing is available on Enterprise plans. To enable this feature, please contact our Customer Care team. Extensions are configured at the Company Level, and can be used on individual and shared lines.

## Extension parameters

Extensions only work between team members within the same Company, unless you set up a [dial-by extension directory](/v1/docs/dial-by-name-or-extension-directory)

Extensions can be 3, 4, 5, or 6 digits long, with five digits being the default. [Contact Customer Care](https://dialpad.com/contact-support) if you'd like to use a 3, 4 or 6-digit extension.
