How to Extract Phone Numbers from Apollo.io: A Step-by-Step Guide

Email outreach gets most of the attention in B2B sales, but cold calling remains highly effective for many sales motions — particularly for enterprise deals where decision-makers are inbox-saturated. Apollo.io is one of the few B2B databases that includes direct-dial phone numbers alongside email addresses, making it a valuable resource for teams running multi-channel outreach. This guide covers exactly how to find, extract, and use phone data from Apollo effectively.

Understanding Apollo's Phone Data Types

Not all phone numbers in Apollo are created equal. When you view a contact's phone data, you'll encounter several different types with different reliability levels:

• Direct dial — The contact's personal work phone or cell number. Highest connect rate, highest data value.
• Company phone — The general corporate switchboard. Low connect rate for reaching specific individuals.
• Mobile — Personal cell number. Very high connect rate but sensitive from a compliance perspective in some jurisdictions.
• Other — Unclassified numbers that could be any of the above.

When building lists for cold calling campaigns, filter for "Direct Phone" specifically within Apollo's contact data. This produces a smaller but significantly higher-quality dataset than accepting all phone number types.

How to Filter and Extract Phone Numbers in Apollo

Apollo doesn't have a dedicated "has phone" filter in all plan tiers, but you can achieve the same result through a few approaches:

1. Build your standard people search with title, industry, and location filters
2. After running the search, sort by "Phone Available" if your plan supports this option
3. When exporting to CSV, include the "Phone" and "Phone Type" fields in your export template
4. Post-export, filter your CSV to rows where Phone Type = "Direct" to isolate the most valuable numbers

Be aware that phone numbers, particularly direct dials, are more expensive in terms of credits on some Apollo plans. Check your plan's credit structure before running large phone-number extractions to avoid unexpected credit depletion.

Validating Phone Data Before Your Calling Campaign

Unlike email verification, phone number validation is less standardized, but several services offer carrier lookup and line-type detection. This tells you whether a number is active, which carrier it's on, and whether it's a mobile or landline. Running this check before your calling campaign eliminates time wasted on disconnected numbers.

Getting Better Phone Coverage Than Apollo Alone Provides

One of the most common frustrations with Apollo's phone data is coverage gaps — many contacts have an email address in the database but no associated phone number. For calling campaigns, this forces you to either skip non-phone contacts or spend time manually researching numbers elsewhere.

Global Data Support addresses this by aggregating phone data from multiple sources and cross-referencing them against company directories, LinkedIn data, and proprietary databases to maximize direct-dial coverage. When you order a lead list through Global Data Support and specify that phone numbers are required, the team sources data specifically from providers with higher phone coverage rates — ensuring you receive a calling list with maximum usable records rather than a mixed file where half the contacts have no phone data.
