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

Hello @Amit Gujarathi 

I tried your expression and I was able to submit with the no space between the +1and the area code

@Amit Gujarathi I tested your expression. I'm still able to submit with no space between the +1 and the area code.

this might work

^1\s\d{3}-\d{3}-\d{4}$

^\+1\s\d{3}[-]\d{3}[-]\d{4}$

or 

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