Why use a San Marino number for WhatsApp?
WhatsApp is the first app most people in San Marino open every day, so a +378 number is what contacts, shops and services there expect to see on your profile.
Businesses registered in San Marino: Companies based in the republic use a +378 number to show a genuine Sammarinese presence rather than an Italian one.
WhatsApp re-verifies whenever you move to a new phone, reinstall or restore a backup, so a number you keep is the only way to stay in control of the account.
