Is Viber popular in Serbia?
Serbia is one of Viber’s strongest markets — it ranks among the countries where Viber is most used. That makes a Viber check especially worthwhile here: a large share of Serbia numbers are likely to be tied to a Viber account, so filtering a list to reachable contacts removes real waste.
In published research, Viber was measured at 90% in Serbia (Rakuten Viber company data - 90%+ of smartphone owners). Read that figure against the base its source states — penetration studies measure different denominators — but it is a useful signal of how common Viber is locally.
Serbia numbers & Viber checks
Serbia phone numbers use the +381 country calling code. Before a Viber check, numbers are normalised to E.164 — the international format with the correct dial code and national length — so mixed local formats in your list do not silently fail. A valid Serbia number looks like +381 XX XXXX XXXX; anything that cannot be normalised to that shape is flagged rather than billed.
