In marketing, verifying a phone number is essential. Statistics show that, on average, people change mobile carriers every 23 months. Consequently, a mobile line only remains valid for that period. This is why businesses need to frequently audit their customer databases to check whether phone numbers are still active.

To handle this, there is no better tool than HLR Lookup. It is the ideal solution for keeping your contact database constantly up to date.

Want to learn more about HLR lookup? Octopush tells you everything you need to know in this guide.

What is HLR Lookup at Octopush?

By definition, HLR Lookup (Home Location Register or Network Query) is a service that allows you to verify that your database is up to date. In other words, it helps you check a phone number to see if it exists and is still valid and active. Additionally, this service allows you to identify which carrier a number is registered to.

In a sense, HLR Lookup allows you to update essential information for your voice and SMS marketing campaigns.

At Octopush, this service is primarily used to verify the validity of the phone numbers in your contact database. If a customer's number is no longer working, HLR lookup notifies you. This allows you to stay current and optimize your SMS deliverability. By doing so, you avoid wasting money by sending messages to obsolete numbers.

Why use an HLR Lookup service to verify a phone number?

For a business to run smoothly, it is vital to constantly strengthen ties with its customers. At Octopush, we prioritize messaging as a way to achieve this. It is a process that allows you to send important information regarding your products, services, or store. Unfortunately, sending SMS has a cost. While the unit price may seem affordable, if you are sending millions of messages a month, the bill can quickly become quite significant.

Of course, these investments are intended to generate a return. However, this only works if the numbers are still valid. Otherwise, you are spending money for nothing. This is why verifying phone numbers is necessary before sending any messages.

By choosing HLR Lookup services, you benefit from:

• Rapid cleaning of your customer list
• Significant reduction in messaging costs by eliminating invalid numbers
• Substantial time savings, as you will no longer send messages to obsolete numbers

Even more features, only at Octopush

In addition to the basic features offered by HLR Lookup, our service also allows you to:

• Check whether a customer contact is valid or invalid. Specifically, determine if a phone number is active, has been deactivated, or was never registered.
• Ensure the message recipient is able to receive it or identify temporary errors preventing SMS delivery. For example, if the phone is turned off or located in an area without coverage.
• Check if the SMS recipient is traveling and therefore outside their usual network area. The service also identifies the network they are currently using.
• Check whether the operator's network is available or not

Who is Octopush's HLR phone number verification service for?

• For businesses and organizations:

Use HLR to keep your list of contacts, employees, and suppliers up to date. Check all the phone numbers in your directory and identify inactive, invalid, deactivated, or roaming numbers.

• For universities and schools:

The HLR service can also benefit schools with large student populations. To ensure important information is received, universities and schools often prefer sending SMS. However, sending SMS to millions of students every year is far from cheap. That is why maintaining an up-to-date student contact database is essential and can save thousands of euros.

• For market research firms, insurance companies, and travel agencies:

Knowing how to verify a phone number can also help you maintain a list of valid prospect numbers—numbers you can use to send messages directly to their mobile phones.

In short, you have everything to gain by using our HLR service. Not only can you easily verify phone numbers, but you can also continuously update your database of customers, prospects, and other types of contacts.
