What Is a Reachability Score?

A reachability score ranks how reachable a phone number is. ScoreMachine returns the score as phone_accessibility, 0 to 10.

Also calledphone_accessibility

Example

phone_accessibility 8 · -100 undetermined

Reachability Score in Practice

Carrier, network and channel signals feed the score. A file sorted on phone_accessibility puts the reachable part at the top. The value -100 means the signals did not settle, not that the number scored zero. Undetermined numbers belong on their own path.
