AI has made human interactions a “premium” experience, one that’s preferred by leads, customers, and candidates alike. However, the spray-and-pray tactics of the past prioritize quantity over quality, making it difficult to personalize conversations – especially when you don’t know if you have the right phone number. That’s why RocketReach partnered with Trestle to verify 100% of our phone database. Over 190 million pre-verified phone numbers are now accessible to Pro, Ultimate, and Custom customers, along with a series of new features.
Connect with leads, every time, with phone confidence grades
Most data providers hand you a list and call it a day. Not sure what type of phone number you’re calling? Figure it out. Wondering if the number’s even active? Sure, but it may not belong to the person you have in mind. While some verification tools confirm a number is “real,” few give you actionable insight into whether or not it matches the person you’re trying to call.
That’s why we’re introducing phone grades to all RocketReach numbers. Phone confidence grades match existing email grades, so you can easily identify and prioritize high-quality numbers.

How it works:
- A grade (Best): Confirmed, valid phone numbers with strong identity match signals.
- A- grade (Likely): Confirmed, valid phone numbers that do not have confirmed identities.
- B grade (Possible): Phone numbers worth trying, especially if better options are not available.
- F grade (Invalid): Invalid numbers are automatically removed from profiles.
New phone numbers are continuously verified and graded to ensure data freshness. In fact, internal testing found that Trestle-verified phone numbers are twice as likely to result in successful connections compared to contacts that have not been verified yet.

Make the right call with enriched phone line types
Imagine this: You found the perfect lead on LinkedIn and you’re eager to get in touch. You call the first number that appears in your search engine, only to realize you called the lead’s personal number during a (well-deserved) family vacation. Not the best first impression, especially if they’re taking time away from work.
There’s a time, place, and occasion for everything, so make the most of your call by distinguishing between mobile, direct dial, and office phone numbers. RocketReach shows you what type of phone you’re dialing, before you call, so you can build relationships in the right settings.

How it works:
- Search for a personal or company profile to view pre-verified phone numbers
- Mobile phones will continue to be visible, as usual.
- Direct dial numbers reach contacts directly, bypassing primary company phones.
- Office phone numbers are company numbers that can be used as an alternative if a mobile or direct dial number isn’t available.
Now, you can meet leads in the middle by dialing the phone lines they prefer.

Conduct smarter research with enhanced phone filters
If you know your ICP like the back of your hand, this one is for you. Our new phone filters refine searches based on your lead’s phone type and confidence grade. Build a lead list of A grade direct numbers, or expand your outreach to A- and B-grade mobile numbers.

How it works:
- Navigate to the Search tab from your RocketReach dashboard.
- On the left-hand side, below “Contact Details,” select “Contact Method” to filter by line type. Mobile, direct dial, and office phones can all be filtered alongside personal and work emails.
- To filter by phone grade, scroll down to “Phone Grade” under “Contact Details” and select the minimum required phone grade you want to prioritize.

Looking ahead
Unverified phone numbers can waste valuable time, resources, and opportunities. While third-party validation tools exist, we don’t believe you should have to pay more to verify data you already purchased.
That’s why RocketReach is proud to offer verified, graded phone numbers at no extra charge. Because that’s how data should be: accurate, trustworthy, and actionable. When used together, these new phone enhancements eliminate the need for manual research and verification. You can spend less time dialing, and more time closing deals.
Looking ahead, we’ll continue investing in our data quality, and exploring new ways for you to leverage RocketReach’s lead intelligence at scale.
