You know that sinking feeling when you inherit a database and have no idea how many numbers actually work?

Maybe it’s a CRM migration.

Maybe it’s a new client handoff.

Or maybe it’s just years of data that’s never been cleaned.

You fire up HubSpot workflows, set up HLR check for one contact at a time… and realize you’re looking at 6 months of gradual progress for a 50,000-contact database.

There’s a better way!

The Problem with Traditional Network Checks

Workflow-based HLR lookups are great for keeping your database clean as new leads arrive. But what happens when you inherit 50,000 legacy contacts?

One-by-one checks via workflows can take months to process a massive backlog. In the meantime:

• Campaigns launching on unverified, stale data

• Sales reps wasting time on dead or disconnected numbers

• Connect rates that tank because 20% of your list is no longer active on a carrier network

• RevOps constantly firefighting data quality issues

Introducing Bulk HLR Lookups

We built the Bulk HLR Service for teams that need results now.

Instead of waiting for contacts to hit a workflow trigger, we query the global telecom network for your entire database at once.

Here’s how it works:

1. Book a quick discovery call (tell us your database size and your priority regions)

2. We perform a high-speed HLR lookup on your unverified records.

3. Your HubSpot contacts get updated automatically with real-time network data

4. You receive a detailed report

What You Get: Real-Time Intelligence

For every contact in the bulk run, we identify the actual status of the SIM card:

We populate your CRM with a comprehensive suite of data points for every contact:

• HLR Status: Know exactly where the line stands with granular statuses like LIVE, DEAD, or ABSENT_SUBSCRIBER.
• Phone Line Type: Instantly segment your list by MOBILE, LANDLINE, or VOIP.
• Phone Carrier: Identify the network provider (e.g., Verizon, Vodafone) currently servicing the number.
• Carrier MCC/MNC: Capture technical Mobile Country and Network Codes for advanced routing.
• Is Phone Ported: Detect if a contact has switched carriers, a key indicator for identity verification.
• Is Disposable: Flag “burner” numbers immediately to protect your database from fake leads.
• Phone Syntax Valid: A foundational check to ensure the number is mathematically possible.
• Last HLR Query: Every record is timestamped, creating a permanent audit trail of your data freshness. “Show me all contacts with live numbers” becomes a one-click filter.

Real-World Scenarios

Scenario 1: The Pre-Campaign Cleanup

A sales team is launching their biggest outbound campaign of the year. They have 50,000 contacts, but no idea how many numbers are good.

Before bulk HLR lookups: They’d either launch blind and waste resources on bad numbers, or spend months checking contacts first and miss their launch window.

After bulk HLR lookups: 24 hours later, they know exactly which 42,000 contacts are reachable. They skip the 8,000 disconnected numbers entirely, saving hundreds of wasted call attempts and boosting connect rates from 15% to 28%.

Scenario 2: The CRM Migration

A company just migrated from Salesforce to HubSpot. They’ve got 75,000 contacts, and data quality during migration is always questionable.

Before bulk HLR lookups: RevOps would spend weeks spot-checking, slowly checking subsets, and still launching with uncertainty.

After bulk HLR lookups: One overnight run reveals 15% of phone numbers are disconnected or unreachable. Now they can prioritize re-enrichment efforts and go live with confidence in their data quality.

Scenario 3: The Quarterly Audit

A well-run RevOps team maintains their database with regular hygiene checks. But with 100,000+ contacts, comprehensive HLR lookups are time-consuming.

Before bulk HLR lookups: They’d run partial audits, sample random subsets, and accept that they’d never check everything.

After bulk HLR lookups: Every quarter, they get a complete live-check report. They maintain database accuracy above 90% and catch disconnected numbers before they impact campaigns.

Why Bulk HLR Lookups Matter

Bad data is expensive.

Every disconnected number your team calls is wasted time.

Bulk HLR Lookups aren’t just about speed, they’re about knowing your data is solid before you build a campaign on top of it. Plan territories around Live contacts and report on real pipeline, not phantom numbers.

Getting Started

Bulk HLR pricing is straightforward and based on volume. We update your HubSpot properties and deliver a detailed health report, helping you segment your “Live” list for immediate action.
