Created Regex Phone number expression for US +1 XXX-XXX-XXXX

[KB30]

Hello I'm working on creating a regular expression for a US phone number. The format needs to be +1 XXX-XXX-XXXX.

I found this post below which provided a Regex expression of ^\(?([0-9]{3})\)?[-]([0-9]{3})[-]([0-9]{4})$ but I'm having issues wit the leading 1.

Does anyone have any tips or assistance on how to complete this? This isn't my strong suit and my first time working on Regex expression so all help would be great!!

@DanielCordick I tried but I can only submit +1. I can not submit a number

Try below

^(\+1)?([0-9]{3})\)?[-]?([0-9]{3})[-]?([0-9]{4})$

this does not allow a space between the 1 and area code

@KB30  try below

^(\+1)?(\s+)?([0-9]{3})\)?[-]?([0-9]{3})[-]?([0-9]{4})$

@Jaspal Singh I can submit with the space between the 1 and the area code but the rest of the format does not work at all for the number.  I can submit numbers with no hyphens

HI @KB30 ,
I trust you are doing great.

Here's a regular expression that matches the phone number format +1 XXX-XXX-XXXX:

^\+1\s?([0-9]{3})[-]([0-9]{3})[-]([0-9]{4})$
