Does this show the current carrier if a number was ported?
Phone validation shows the original carrier from numbering-plan data. For the current carrier and porting status, use the carrier lookup (3 credits), which asks the live portability database.
Which countries are supported?
Validation, formatting and line type work for every country. Original carrier, spam reports and live carrier data are for US numbers (live carrier: US and Canada).
Am I charged for invalid numbers?
No. Numbers that can't be parsed are answered free.
