triple check
Confirm three times
Triple check is to verify something three times for certainty, usually because the stakes are high or you're prone to error: Triple check the address before you mail it.
The phrase emphasizes thoroughness beyond ordinary care—if double checking isn't enough, triple checking might catch what you missed.
