Which provider has the best US mobile numbers?

ZoomInfo, for sheer volume: around 135M direct-dial and mobile numbers claimed, the deepest US coverage in the category. For connect quality specifically, Cognism's phone-verified "Diamond" mobiles lead the market, though its US coverage is only moderate.

What's the difference between a direct dial and a mobile number?

A direct dial reaches a person's desk or extension without going through a switchboard; a mobile number reaches their cell phone. Mobiles are usually more valuable for outbound because they reach the person directly, but they're also harder to source accurately.

Is it legal to cold call from a bought US number list?

Cold calling in the US is governed by the TCPA, not CAN-SPAM (which covers email). Before calling, you must scrub numbers against the National Do Not Call Registry, and autodialed or pre-recorded calls carry strict rules and consent requirements; fines run to thousands of dollars per call.

The best B2B mobile number databases for US teams

In short

For US mobile and direct-dial data, ZoomInfo carries the most volume (around 135M numbers claimed, the deepest in the category) while Lusha and Apollo are cheaper self-serve routes to US dials. Lead411 verifies its direct dials twice; RocketReach adds mobiles on higher tiers. Here's how the five compare on coverage and price.

1

ZoomInfo

The deepest US B2B database, with intent, visitor-ID and enrichment in one platform, at an enterprise price.

7.3 /10

The volume leader for US dials: around 135M direct-dial and mobile numbers claimed, the deepest in the category. Pricing is enterprise-only (Vendr median ~$33,500/yr) and accuracy decays on older records, so verify before high-volume dialing.
- Entry price ~$14,995/yr
- Pricing Demo-gated
