Why use a Czechia number for Coinbase?
Day-to-day life in Czechia runs on Messenger, WhatsApp and Instagram, yet Coinbase remains the app for a stable 2FA number for a crypto account. A +420 number keeps that account tied to the country without using your personal SIM.

Coinbase sends sign-in and recovery codes to the number on file.
