Phone Number Validation

Is there a way to require a valid phone number format on the checkout page? I know I can’t check the phone number to make sure it’s valid, but I want to at least require users to enter in the format 555-555-5555 so they don’t accidentally leave an incomplete number.

this would be sooooo useful. Right now you can even write “hhhjhnkhn” as phne number and it is fine.

I’d like to have the phone format for my country, 9 digits and this way: 555 555 555

That would be perfect to avoid mistakes or false info like rtysgshsaasgh
