Flags vary by carrier, location and more. ARMOR® delivers location-specific results on AT&T, Verizon, & T-Mobile—far more accurate than the flawed "call a friend" method.

It gives us confidence and credibility when delivering results, plus, it’s become an essential part of our number verification workflow.”
