Bulk Verification Tools for Phone Number and Prospect Details

as a BDR i use full enrich to get the phone numbers of the prospects whom I want to call but most of the prospects that I call are not the same whose details i get from full enrich which of course turns out to be the wrong number. I have around 600 phone numbers with the person's details. How do I bulk verify the names of the person associated with these phone numbers and their details? is there a tool or way using which I can do the same? if yes, list out all the tools else list out the ways to verify them.
