// The Basics
What is the +31 country code?

Dutch numbers drop the leading 0 internationally — an Amsterdam number written domestically as 020 123 4567 becomes +31 20 123 4567.
Calling culture
Dutch business culture is famously direct — calls tend to get to the point quickly, and lengthy small talk before business is less common than in many other markets.
