Detail
Why cell numbers change connect rates
Main lines route to reception, which means a gatekeeper conversation before a sales conversation, if you get one at all.
A mobile puts the call in the buyer's hand. Connect rates commonly run several times higher than switchboard dialing.
The trade is that mobiles are harder to source, which is why so many files quietly pad themselves with office numbers.

How to spot padded phone data
Sort by phone number. Any number appearing more than once is a shared line, not a personal one.
Look for extensions. A number with an extension is a desk inside a switchboard, whatever the column header says.
Check the line type label. If a vendor cannot tell you whether a number is mobile, assume it is not.

Calling mobiles responsibly
These are business contacts reached in a business context, and the same courtesy rules apply as any other channel.
Honor opt outs immediately and permanently. Suppression requests here are actioned within one business day.
Keep a suppression list of your own and share it, so the same person is never sourced again.
Checklist
What to insist on
One number, one person
No number should appear twice across the file.
Line type stated
Mobile or direct dial, labelled, not guessed.
No extensions
An extension means a switchboard sits in front of it.
Matched employer
The number should be tied to the company on the record.
Replacement policy
Wrong numbers replaced free, with a visible flag rate.
FAQ
Questions buyers ask
What share of records have a mobile?
Most released records carry a mobile. Where one is not confirmed we deliver an explicitly direct line, or nothing at all.
Do you cover the UK and Europe?
Yes, with a higher proportion of direct dials than North America.
Can I get mobile only?
Yes, ask for mobile only and direct dial records are excluded from delivery.
What is on every contact you deliver?
Full name, job title, company, a verified work email and a mobile number or confirmed direct dial. Most records also carry a professional profile link. Nothing is released without the phone and the email.
What happens if a number is wrong?
Flag it in the portal and a replacement is queued free of charge within fair use limits. The flag rate for your account is visible to you at all times.
Is there a contract?
No. Plans are monthly, from $49 for 200 prospects to $799 for 10,000, and you can change volume or stop at the end of any month.
