What is HLR lookup mobile number validation??

The HLR validation (Home Location Register or also called Lookup) verifies the status and availability of a mobile number, determining its validity and current usage. It also provides information about the operator and network associated with the mobile number and its format.

It is an essential tool for keeping cell phone databases up to date, discarding invalid numbers and allowing users who have changed their contact number to update their data.

The HLR service improves the effectiveness of any SMS sending or campaign and reduces sending to invalid numbers and their cost.

How does the HLR mobile number validation work?

LabsMobile and its partners have updated databases and direct connection with telephone operators to know if a number is in use and which operator or telephone network it corresponds to.

This service is available in more than 200 countries with full accuracy and guarantee. However, there are different types of coverage and levels of service, ask us about your specific case.

HLR Query Process

The HLR is a centralized database that stores crucial information about the subscribers of a mobile network. Contains data such as:

• Phone number (MSISDN)
• Subscriber identity (IMSI)
• Number status (active, inactive, suspended)
• Current network information (VLR - Visitor Location Register)
• Associated service configuration

Involved Actors

• Service Requester: The company that sends the query request, usually an SMS messaging platform.
• Telecommunications Gateway: Provider that manages the communication with the mobile network.
• Mobile Network Operator: Responsible for maintaining the HLR and providing the requested information.

Flow of an HLR query

1. Request Generation: The messaging platform sends a query request through the telecommunications gateway.
2. Connection with the Operator: The gateway uses standard protocols such as SS7, MAP or DIAMETER to connect to the HLR of the corresponding mobile operator.
3. HLR Check: The HLR checks the status of the queried number and the network where it is registered.
4. HLR Response: The HLR sends a response with the requested information.
5. Results Processing: The platform processes the data and updates its database.

Response Time of an HLR Query

The mobile network operator provides accurate and up-to-date information about the queried number, including its current status, network of registration and possible roaming.

This service is available in our Web application and also integrating with our API. See the HLR API documentation to learn how to integrate and automate this service.

Benefits of Performing an HLR Check

Operational Efficiency and Optimization

Maintaining updated databases is essential for any company that handles large volumes of contacts. An HLR Check allows you to clean obsolete records, improving accuracy and operational efficiency by generating actions for data updates.

Cost Reduction in SMS and Call Campaigns

Performing accurate or periodic HLR queries is an effective tactic to reduce operating costs. By removing inactive numbers from databases, businesses save on mailing costs and improve their return on investment (ROI). This also allows for more targeted and successful campaigns.

Fraud and Abuse Prevention

Querying the HLR helps identify potential cases of fraud or abuse, such as fake numbers, duplicate or temporary users used in fraudulent activities.

Better Customer Experience

By ensuring that messages reach only valid numbers, businesses improve customer experience, avoiding instances of typos or oversights.

Regulatory Compliance

Many privacy and telecommunications regulations require businesses to maintain accurate and up-to-date databases.
