How to use
Enter an Australian (0412…, 02/03/07/08…) or international (+CC…) number. The checker validates format, identifies carrier and line type, detects VoIP ranges, analyses number patterns, scores against a scam database, and assesses CLI spoofing risk.
CLI spoofing means a scammer forges a real mobile number as their caller ID —
the call actually originates from VoIP infrastructure overseas.
No tool can confirm spoofing with certainty without STIR/SHAKEN carrier data,
but this checker flags strong indicators.
Set TWILIO_ACCOUNT_SID +
TWILIO_AUTH_TOKEN on the server for live enrichment.
