🚨 The April 24 #fridaygeotrivia game begins 🚨

Today we consider country calling codes - the phone number prefixes used to route calls to different countries. For example +49 for DE 🇩🇪, +61 for AU 🇦🇺, etc.

What is the longest chain of countries such that each successive country/territory in the chain shares a land border with and has a calling code greater than the previous one?

Example chain: FR 🇫🇷 (+33) - ES 🇪🇸 (+34) - PT 🇵🇹 (+351)
