Regex for +1 123-123-1234 javasacript

Question

What is the regex pattern for: +1 123-123-1234

Current I am using /^\\(?(\\d{3})\\)?[-\\. ]?(\\d{3})[-\\. ]?(\\d{4})$/ /^\\(?(\\d{3})\\)?[-\\. ]?(\\d{3})[-\\. ]?(\\d{4})$/ /^\\(?(\\d{3})\\)?[-\\. ]?(\\d{3})[-\\. ]?(\\d{4})$/ which can validate 123-123-1234 but I have +1 followed space. So how to update the above pattern for that?

Searched on many sites, but couldn't find any.

Thanks in advance.

Answer 1

Here you go:

\\+1([- ])?\\d{3}-\\d{3}-\\d{4}

I made it so that the +1 can be followed by either a space or a dash, optionally.

Edit: here it is with the first 3 digits in optional brackets aswell

\\+1([- ])?\\(?\\d{3}\\)?-\\d{3}-\\d{4}

So, you could have +1 (123)-123-1234
