Phone Number Enrichment

Add phone numbers to your lead enrichment for multi-channel outreach.

Overview

Phone Number Enrichment finds direct dial and mobile phone numbers for your leads. Perfect for cold calling, WhatsApp outreach, or multi-channel campaigns.

What You Get

When phone enrichment is enabled, Hyperscale finds the best available phone numbers from publicly available business sources.

Note: Unlike email addresses (which are verified for deliverability), phone numbers are sourced but not verified. We provide the best available phone numbers we can find.

How It Works

Phone enrichment integrates seamlessly with lead enrichment:

1. Discovery → Finds phone numbers from public business sources

2. Formatting → Standardizes to international format

3. Result → Clean, ready-to-dial phone numbers

Pricing

Additional credits per lead (in addition to base email enrichment cost)

Phone enrichment costs significantly more than email-only enrichment. Check your subscription page for current pricing.

Billing Model

Same as email enrichment - upfront charge, automatic refunds:

Example:

• Request 100 leads with phones

• Results: 85 emails found, 70 phones found

• Refund: Automatically refunded for leads where email or phone wasn't found

• Final cost: Only charged for successfully enriched data

You're only charged for leads where BOTH email and phone were found.

Phone Number Format

All phone numbers are formatted in international E.164 format:

This format works with:

• ✅ Dialers and auto-dialers

• ✅ CRM systems

• ✅ Click-to-call tools

Data Sources

Phone numbers come from multiple verified business data sources including:

• Public business directories

• Company websites

• Professional databases

• Verified contact information

All numbers are sourced from publicly available business information.

Quality & Accuracy

Phone Verification

Every phone number is verified before being charged:

• ✅ Valid format

• ✅ Active number (not disconnected)

• ✅ Correct country code

Accuracy Expectations

• Direct dial numbers: 85-95% accuracy

• Mobile numbers: 70-85% accuracy

• Disconnect rate: 5-15% (people change jobs)

What "Accuracy" Means

• ✅ Number connects

• ✅ Right company

• ⚠️ May not reach exact person (could be desk line shared by department)

• ⚠️ Person may have left company (data aging)

Data Freshness

Phone numbers are updated regularly but can become stale:

• 0-3 months old: Highest accuracy (90%+)

• 3-6 months old: Good accuracy (80-90%)

• 6-12 months old: Moderate accuracy (70-80%)

• 12+ months old: Lower accuracy (60-70%)

If you get a disconnect, request a refund at [email protected].

HubSpot

• Syncs to "Phone Number" field

• Mobile numbers preferred over direct dial

• Formatted for click-to-call

Close.io

• Properly formatted for Close's dialer

• Tagged as "mobile" or "work"

Privacy & Compliance

Data Sources

• All phone numbers from public business directories

• No personal cell phone scraping

• Complies with data protection regulations

Do Not Call Lists

Hyperscale provides phone numbers but does NOT:

• ❌ Check against Do Not Call registries (your responsibility)

• ❌ Guarantee compliance with telemarketing laws

• ❌ Provide legal advice on cold calling

Your responsibility:

• Check local Do Not Call laws

• Maintain your own suppression list

• Follow TCPA (US), GDPR (EU), and local regulations

Best Practices

1. Test First

Start with a small batch (10-20 leads) to test:

• Phone match rate for your target audience

• Number quality and accuracy

• ROI vs. email-only approach

2. Multi-Channel Sequences

Use phones as part of a sequence:

1. Email introduction

2. LinkedIn connection request

3. Phone call follow-up

4. Email follow-up

Don't rely on phones alone - integrate with other channels.

3. Time Your Calls

• Best times: Tuesday-Thursday, 10am-12pm and 2pm-4pm local time

• Worst times: Monday mornings, Friday afternoons, lunch hours

• Time zones: Always call during business hours in lead's timezone

4. Prioritize High-Value Leads

Phone enrichment costs significantly more than email-only. Use it for:

• ✅ Enterprise deals worth $50k+

• ✅ C-suite executives

• ✅ Hard-to-reach decision makers

• ❌ Not for low-ticket, high-volume products

5. Keep Good Records

Track outcomes in your CRM:

• ✅ Connected / Voicemail / Wrong number / Disconnected

• Use this data to refine future searches

• Request refunds for disconnected numbers

Troubleshooting

"Phone number not found for most leads"

This is normal. Match rates vary by:

• Industry: Tech has lower rates

• Seniority: Executives harder to find

• Geography: International lower rates

• Company size: Startups harder than enterprises

Typical match rate: 50-70%

"Phone number is disconnected"

People change jobs frequently. If multiple numbers are disconnected:

1. Forward details to [email protected]

2. We'll credit your account

3. Consider targeting more stable roles (not startups)

"Only got direct dial, not mobile"

Mobile numbers are harder to find. We provide whichever is available:

• Direct dial > Mobile > Both > Neither

• You're charged if we find either

"Phone enrichment toggle is disabled"

Phone enrichment only available for FULL searches (not LINKEDIN_ONLY).

Refund Policy

You're automatically refunded if:

• ✅ No phone number found

• ✅ Email found but no phone (refund for phone cost only)

Manual refunds if:

• ✅ Disconnected number (email [email protected])

• ✅ Wrong person's number (clearly inaccurate)

Not refundable:

• ❌ Person doesn't answer (valid number, just no answer)

• ❌ Gatekeeper/assistant answers (number works, just screened)

• ❌ Voicemail only (valid number)

Cost Comparison

Email Only

• Lower cost per lead

• Best for: Email campaigns, newsletter growth, warm outreach

Email + Phone

• Premium cost (significantly higher)

• Best for: Cold calling, multi-channel, high-value deals

When Phone ROI Makes Sense

Break-even analysis:

• Email response rate: 2-5%

• Phone connection rate: 20-40%

• Sales cycle: Phones accelerate deals

If your deal size is $10k+, the premium phone enrichment cost often pays for itself in faster closes.
