Trestle Now Supports International Phone Number Validation
Trestle is committed to helping businesses verify, validate, and improve the quality of their contact data because better data means better decisions. And now, we’re excited to announce a major enhancement to our Phone Validation API: International phone number validation is officially live. Whether you’re reaching customers in Brazil or scaling SMS campaigns across Europe, our API can now validate numbers from over 200 countries worldwide.
Why This Matters
Until now, our real-time phone validation focused primarily on U.S. numbers — delivering phone metadata like line type, carrier, and our proprietary Phone Activity Score to detect disconnected or low-quality numbers.
But as your business grows globally, so should your tools. That’s why we’ve expanded our coverage to help you:
- Detect invalid or improperly formatted numbers across international dialing codes
- Identify seven unique line types, including mobile, fixed and non-fixed VoIP, landline, premium, toll-free, and voicemail service.
- Get carrier-level insights from over 18,000 carriers
- Avoid unreachable numbers with Phone Activity Score before wasting time or budget on leads that won’t likely connect
The Same API, Just Global
We’ve made it incredibly easy to start validating global numbers. There’s no new endpoint to integrate and it’s already live for anyone validating numbers with Phone Validation API.
You’ll get structured JSON data that includes:
- Validity status (true or false)
- Activity Score (0-100)
- Country calling code (e.g., 61)
- Country code (e.g., AU)
- Country name (e.g., Australia)
- Line type (e.g., mobile, landline, fixed VoIP, non-fixed VoIP, etc.)
- Carrier (e.g., Vodafone Network Pty Ltd)
Built for Global-First Teams
Whether you’re cleaning international lead lists, preventing SMS fraud, or enriching user profiles, this update helps your team:
- Expand confidently into new markets
- Stop junk numbers at the source
- Improve the ROI of your outreach and campaigns
- Protect your sender reputation by reducing failed messages
