Unknown calls in Singapore

Unsure about a Singapore number? Explore concise community notes to judge calls and texts. You’ll see both legitimate callbacks (deliveries, banking, appointments) and waves of robocalls or phishing. Ranges like 6 (fixed lines) and 8/9 (mobile), plus 1800 toll‑free, are useful context but not proof of identity or exact location due to portability and VoIP — treat them as hints, not evidence.

Verification: return calls via the official number on the company website/app, check in‑app notices, and never share one‑time codes by phone. Use device/carrier blocking for repeat issues and leave a short, factual note here so others benefit from your experience.
