HLR Status Property

Track the detailed reachability status of contact phone numbers

Overview

Clean Dial's HLR Status property automatically tracks the real-time reachability status of each contact's phone number. Unlike simple valid/invalid flags, this property provides detailed network status codes, allowing for smarter segmentation (e.g., distinguishing between disconnected numbers and those that are just temporarily unreachable).
HLR Status Custom Property

How It Works

When contacts pass through a Clean Dial HLR Lookup workflow action, the system:
    Queries the global mobile network for the number's status
    Maps the network response to a standardized status code
    Updates the HLR Status dropdown property on the contact record

Property Values

The hlr_status property is a dropdown select with the following options:
Value
Meaning
Actionable Advice
LIVE
The number is active, registered, and reachable.
Safe to call or text.
DEAD
The number is confirmed invalid or disconnected.
Remove from lists to save money.
ABSENT_SUBSCRIBER
The number is valid, but the device is off/out of coverage.
Retry later; do not delete.
NO_TELESERVICE_PROVISIONED
The number exists but cannot receive SMS/Calls.
Do not use for SMS marketing.
NO_COVERAGE
Status could not be determined due to network coverage.
Try again later.
UNKNOWN
The network returned an inconclusive response.
Treat with caution.

Setting Up the Custom Property

To view HLR status on your contact records:
    Navigate to CRM > Contacts
    Select any contact record
    Go to the Key Information section
    Click Actions > Customize Properties
    Search for "HLR Status"
    Add the property to your view

Use Cases
