Phone number check tools ranked

Steps

1. 1

   Test it with your own list, not their demo.

   Pull 200 numbers you were going to call this week anyway. A demo list is picked to look good. Yours is the one that matters.

2. 2

   Run the same list through the tool.

   Save the line type and score for each number in a new column of your sheet or CRM.

3. 3

   Check 50 contacts by hand.

   Call or look up each one. Write down if it was the right person, a front desk, a dead line or a wrong number.

4. 4

   Compare the score to what happened.

   Did the low scores really fail and the high scores really connect? A front desk can score high, because these tools check the line, not the person.

5. 5

   Pay month to month or pay as you go before you sign a yearly deal.

   Trestle is pay as you go. Others ask for a monthly plan or a yearly contract, so start small.

6. 6

   Drop it if more than 20% is wrong.

   That's Kevin Hopp's rule. If 1 in 5 of the numbers it calls good turn out bad, the tool is not saving you time.

Check a sample of 50 numbers

You are helping me test a phone check tool before I pay for it. I will paste 50 rows. Each row has: name, company, phone, the tool's line type, the tool's score, and what happened when I called (right person, front desk, voicemail, dead line, wrong person).

Make a short table that shows, for each score band (0 to 30, 31 to 70, 71 to 100), how many calls reached the right person and how many were bad. Then tell me in 3 plain sentences if the score matched real life, and if more than 20% of the numbers it called good were wrong.

Rows: [paste 50 rows]

Compare two tools on the same list

I ran the same [number] phone numbers through two tools: [Tool A] and [Tool B]. Here are the results side by side, plus what happened when I called: [paste rows].

Tell me which tool flagged more of the numbers that really turned out bad, which one wrongly cut good numbers, and the cost per good number for each if [Tool A] costs [price] and [Tool B] costs [price]. Keep it under 150 words and use plain words.

Questions to ask a sales rep before buying

I'm about to get on a call with a sales rep for [tool name], a tool that scores phone numbers before I call them. I run [number] reps who call [type of buyer].

Write 8 short questions I should ask. Cover: price per number, monthly minimums, contract length, refunds, how they score a number, how often the data updates, if I can test it on my own list first, and what happens to my data. Plain words, one line each.

FAQ

Can a phone check tool tell me if the right person will answer?

No. These tools check the line, not the person. A main office number can score high and still ring a front desk, so trust the call over the score.

What score should I cut at in Trestle?

Trestle's own team told us to cut numbers scored 30 or below. Test that cut on your own list and check 50 by hand.

Do I need a phone check if my data tool already says verified?

Yes, if you call a lot. A verified label is the data tool's guess. A quick line check costs very little next to a rep's time on dead numbers.

Which one should a solo seller start with?

Trestle, because it's pay as you go with no monthly fee. The others need a monthly plan or a yearly contract.
