Frequently asked questions
Is the country calling code the same as the customs country code?
No; phone country codes follow international telecom numbering, while customs region codes serve a different purpose.
Does an area code alone constitute a valid phone number?
Requires correct local number and area code; please verify according to target country dialing rules.
