Question about Thailand shows!!!

sooooo the AllTicket website won't let me create an account without a phone number (which for some reason needs to start with a 0) so i just entered a random number to get through to ticket selection just to see if it would work. is this okay? like do i need a thai phone number to legitimately purchase these tickets and attend the show? or can foreigners purchase tickets for these two shows as well. im from canada btw. i thought thailand's country code was +66?
