Is LINE popular in Taiwan?
Taiwan is one of LINE’s strongest markets — it ranks among the countries where LINE is most used. That makes a LINE check especially worthwhile here: a large share of Taiwan numbers are likely to be tied to a LINE account, so filtering a list to reachable contacts removes real waste.
In published research, LINE was measured at 94% in Taiwan (LY Corp via Business of Apps 2025 - 22M MAU, ~94% of population). Read that figure against the base its source states — penetration studies measure different denominators — but it is a useful signal of how common LINE is locally.
Taiwan numbers & LINE checks
Taiwan phone numbers use the +886 country calling code. Before a LINE 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 Taiwan number looks like +886 XX XXXX XXXX; anything that cannot be normalised to that shape is flagged rather than billed.
