How to Find Any Business’s Email and Phone Number (Free and Paid Ways)
The fastest reliable way to find a business’s email and phone: check the business’s website contact page and maps listing first (phone is usually public), then use email patterns (info@domain.com, first.last@domain.com) verified with a checker. At scale, automate the whole loop with a tool like RadarLeads — one search returns the business, its public phone and a verified contact email — from $29/month with a free 15-lead trial.
Who should use this?
This guide is for anyone who needs working contact details for businesses, not people. It fits:
- Agencies and freelancers building outreach lists for local businesses
- Sales reps prospecting SMB accounts phone-first or email-first
- Recruiters and partnership managers reaching specific locations
- Anyone who tried scraping maps and got stuck on emails
- Teams needing hundreds of verified contacts per week, not one-offs
How it works
Five methods, from free and manual to automated — start where your volume is:
- 1
Check the website contact page
Most businesses publish email or a contact form plus phone on their site (footer, /contact, /about). Search "business name + city" on Google, open the site and look at header, footer and contact page. Time: 2-5 minutes per business.
- 2
Read the maps listing
Google Maps and Apple Maps listings carry the public phone number, hours and website link for nearly every registered local business. It is the most reliable source for phones; it rarely contains emails.
- 3
Guess the email pattern — then verify
Common patterns: info@domain.com, hello@domain.com, first@domain.com, first.last@domain.com. Guessing is free, but sending to unverified addresses burns your sender reputation — always run a verification check before adding to a list.
- 4
Use a lookup tool for stubborn domains
Domain-level tools (Hunter and similar) find published addresses for a known domain. They solve single lookups well; the bottleneck appears when you do not have the domain list yet.
- 5
Automate the full loop at scale
RadarLeads collapses the five steps into one search: pick industry and city, get businesses with public phone, website and a verified contact email per business, then export to Excel or CSV. Free 15-lead trial to test it on your market.
Which method fits your volume
Match the method to the number of businesses you actually need:
| Method | Cost | Volume | Verified? |
|---|---|---|---|
| Website + contact page | Free | 1-5 per day | As good as you check |
| Maps listing | Free | 1-10 per day | Phone: yes; email: rare |
| Email pattern + checker | Free-$ | 10-50 per day | Only with verification |
| Domain lookup tool | $ | 50-200 per day | Mostly |
| RadarLeads | Flat from $29/mo | 300-5,000 per month | Yes, verified at source |
What each method actually returns
The trade-offs that decide which mix to use:
| Method | Phone | Time per lead | |
|---|---|---|---|
| Manual website check | Usually | Often | 2-5 min |
| Maps listing | Yes | Rarely | 1-2 min |
| Pattern + verification | No | Sometimes | 3-6 min |
| RadarLeads | Yes, included | Yes, verified | Seconds (batch) |
Best choice
For a handful of businesses, the free loop wins: contact page for email, maps for phone, pattern-plus-verification as fallback. Past ~20 businesses per week, manual methods quietly cost more than a subscription — RadarLeads returns industry-and-city lists with public phone, verified email and need signals in one search, with a free 15-lead trial to confirm quality on your own market before paying.
Frequently asked questions
How do I find a business email address for free?
Check the business’s website contact page, about page and footer first — most publish an address or form. If absent, try standard patterns (info@, hello@, first.last@domain.com) and verify them with a free email checker before sending. This works well for a few businesses per day but does not scale.
How do I find the phone number of a local business?
Google Maps and Apple Maps listings carry the public phone for almost every registered local business — search the business name and city and read the listing. For batches of hundreds, RadarLeads includes the public phone with every result in the exported list.
Is it legal to email businesses I found online?
Cold-emailing businesses is generally permitted under rules like CAN-SPAM (US) when you identify yourself, avoid deceptive subject lines and honor opt-outs; GDPR (EU) allows legitimate-interest B2B contact under the same good practices. Always email the business role rather than personal addresses without basis, and keep records of your sources.
What is the fastest way to build a list of business emails?
Automated discovery: a RadarLeads search by industry and city returns businesses with a verified contact email each, exportable to Excel or CSV in one click — hundreds of contacts in the time manual methods produce a dozen. The free 15-lead trial lets you test output quality first.
