How to use it.
- 1
Keep one row per person
If a contact has two numbers, keep the one you'd dial first in phone and remove the rest, or add a second row.
- 2
Fill first and last name
The check confirms the number belongs to the name, so blank names cost you the most useful signal.
- 3
Write numbers in E.164
+1 followed by ten digits, no spaces. Most formats are accepted, but E.164 avoids surprises.
- 4
Keep a record ID
It's how you'll join the checked file back to your CRM.
- 5
Check, then split
Dial High chance and Low chance. Send Bad data to email and LinkedIn.

Questions, answered.
Do I need to use these exact column names?
No. When you upload a CSV, the name and phone columns are found for you. These names just make the file easy to reuse.
Can I add my own columns?
Yes. Every original column comes back in the checked file, in the same order.
