How do you allow dashes (hyphens) to be used in a number column in SharePoint? SharePoint only allows numbers and nothing else in number columns. Is there a formula or a calculated column that can be used to solve this issue?

As Rodrigo has mentioned you cannot use hyphens on a number column. Another way is to create a single line of text column and use Input mask to force the user to enter value in certain format.

Check the reference: Input mask on textbox in SharePoint list form

You have to enter below script on your list form

<script language="javascript" src="http://code.jquery.com/jquery-1.4.2.min.js" type="text/javascript" ></script>
<script language="javascript" src="http://jquery-joshbush.googlecode.com/files/jquery.maskedinput-1.2.2.min.js" type="text/javascript" ></script>
<script language="javascript" type="text/javascript">

The above script will force the user to enter only number in US phone format.


You can't use hyphens on a number column (unless is a negative number). You should use a text column with a validation formula.

For example, lets say you want to store a phone number with the format xxx-xxx-xxxx.

The formula then would be:
