Help on regex for phone number format XXX-XXX-XXXX

[dianeramos]

We have a requirement to have a standard format for the phone number field to be XXX-XXX-XXXX (with hyphens). Do you have any suggestions how i can achieve this by validation regex?

Thank you in advance

Try this

^([0-9]{3}-){2}[0-9]{4}$")

Sharing one more combination

/^(?:\(\d{3}\)|\d{3}-)\d{3}-\d{4}$/

Hi Diane,

We use this Regular Expression in a Variable Validation Regex for US Phone Numbers.

^\(?([0-9]{3})\)?[-]([0-9]{3})[-]([0-9]{4})$
