Yes, the addresses or phones returned as part of Reverse Phone API, Reverse Address API, or Find Person API are all ranked. These rankings are based on the internal algorithms that use metadata signals from our providers and the association dates between the person or business and addresses or phone numbers. The rankings help businesses prioritize which phone numbers to call or what addresses to use for maximum engagement with people of interest.
What is the ranking based on?
For phones, the ranking indicates how confident we are about the association between the person or business and the address. So, the higher a phone number is in the order, the more confident we are about the phone’s association with the person or business. They are not ranked based on line type or phone activity. This means that for a phone disconnected signal (i.e., low activity score), we wouldn’t immediately remove the linkage because it might be temporary, or we wait until we see a new linkage for that number. Hence, we do recommend using our Phone Validation API to check the activity score on those phones to confirm they are active and appropriately decide the prioritization.
For current or historical addresses, the ranking is sorted by how recently the addresses linked to the person or business. So, the most recent address linkage to the person is at the top, while the older ones are lower.
