Stop Dialing Dead Numbers: Databar.ai Partners with Trestle for Phone Validation

How much time does your sales team waste calling numbers that ring out, bounce to a generic voicemail, or simply no longer exist? According to industry estimates, up to 30% of phone numbers in a typical B2B database go stale every year. That means nearly a third of your outreach could be hitting dead ends before a conversation even starts.

Today, we're announcing our partnership with Trestle, bringing their trusted phone validation API directly into the Databar.ai platform. Databar.ai users can now validate phone numbers, check carrier details, identify line types, and flag disconnected numbers - all  right inside your enrichment process.

This integration gives sales, marketing, and operations teams instant access to Trestle's phone number verification capabilities through our native interface. No complex API setup. No developer dependency. Just accurate phone intelligence at your fingertips.

"Trestle's dedication to identity data accuracy and their phone intelligence make them a strong addition to our platform. With global coverage across 200+ countries and an enterprise-grade infrastructure serving billions of queries, this is exactly the caliber of data provider our users expect from Databar.ai," - David Abaev, Co-Founder & CEO at Databar.ai.

Why Phone Validation Matters

Every outbound call to a disconnected number costs time and money. Every SMS sent to an invalid number chips away at your sender reputation. And every fake phone number that slips through your sign-up form increases fraud risk.

Phone number validation solves these problems before they start. By checking whether a number is active, identifying the carrier and line type, and scoring the likelihood that someone will actually pick up, you can prioritize the contacts that matter and skip the ones that don't.

Trestle's Phone Validation API does all of this and now it's available inside Databar without any technical setup.

What You Can Do with Trestle via Databar.ai

Phone Number Validation

The Trestle integration allows you to:

• Validate any phone number globally - check whether a number is valid, properly formatted, and assigned to an active subscriber across 200+ countries and territories
• Get a Phone Activity Score - Trestle's proprietary score (0–100) tells you how likely a number is to be connected. A score of 70+ indicates high confidence the phone is active, while 30 or below suggests a disconnected or inactive line
• Identify the carrier - see which telecom provider operates the number, including MVNOs, for both domestic and international numbers
• Determine the line type - distinguish between seven unique classifications: mobile, landline, fixed VoIP, non-fixed VoIP, premium, toll-free, and voicemail service
• Check prepaid status - find out whether a mobile number is on a prepaid plan, which can be an important signal for lead quality and fraud assessment

Phone Metadata and Intelligence

Beyond basic validation, the integration returns rich phone metadata that helps you segment and score your contacts:

• Country details including country code, calling code, and country name for international number intelligence
• Validity checks confirming the number is properly assigned to a carrier and currently in service
• Unique request IDs for audit trails and data tracking across your workflows

Each validation returns a complete profile for the phone number, giving you everything you need to decide whether to call, text, or remove a contact from your list.

Use Cases for Phone Validation

Lead Qualification and Prioritization

Not every lead in your CRM is worth a call. With Trestle's phone validation inside Databar, sales teams can score and rank leads based on whether their phone number is active and reachable. Filter out disconnected numbers, flag non-fixed VoIP lines that may signal temporary or low-quality leads, and focus your reps on contacts with the highest chance of picking up.

This is especially valuable for teams dealing with high-volume inbound leads where speed-to-contact matters. Validating phone numbers before they enter your dialing queue means fewer wasted dials and more live conversations.

Outbound Dialing and SMS Optimization

If you run outbound sales campaigns or SMS marketing, phone validation directly impacts your results. Sending texts to landlines wastes credits. Calling disconnected numbers tanks your connect rate. And poor data quality makes it nearly impossible to measure true campaign performance.

By running your contact lists through Trestle's validation before launching a campaign, you can separate mobile numbers from landlines, remove inactive numbers, and ensure your messages reach real people. The line type data is particularly useful here - knowing whether a number is mobile vs. fixed VoIP vs. landline lets you route each contact to the right channel automatically.

Database Cleaning and CRM Hygiene

Phone numbers decay over time. People switch carriers, cancel lines, and change numbers. If you haven't validated your contact database recently, a significant portion of your records may already be outdated.

Running a bulk validation through the Trestle integration in Databar helps you identify and remove stale records, update line type classifications, and maintain a clean, accurate contact database. This pays dividends across every team that touches your CRM. From sales reps who need reliable numbers to marketing teams tracking campaign attribution.
