Questions
What is the country code for Switzerland?
Switzerland's country calling code is +41. In E.164 — the format almost every API, SMS gateway and CRM expects — it is written with no spaces, brackets or dashes, like +41781234567.
How many digits is a Switzerland phone number?
9 digits after the +41 country code. Written nationally it may show a leading 0 trunk prefix, which is dropped in international form.
Does the leading 0 get included when dialling Switzerland from abroad?
No. The 0 is a national trunk prefix used only inside Switzerland. Dialling internationally you drop it and use +41 instead — this is the single most common cause of "invalid number" errors in signup forms.
Is a correctly formatted number the same as a real one?
No, and conflating the two is the usual mistake. Formatting only says a number could exist. It does not say whether the range was ever allocated, whether it is mobile, fixed line or VoIP, or whether it is worth trusting on a signup — those need a lookup against numbering-plan data.
