Mobile phone numbers are playing an increasingly important role in the field of professional communications, as well as in interactions between businesses and their customers. For those deploying SMS sending campaigns or managing reservation websites, verifying the validity of phone numbers is of paramount importance. In this article, discover the main reasons why it’s essential to verify the validity of mobile numbers, and what options are available to you.
3 Good Reasons to Verify the Validity of Your Mobile Phone Numbers
1) Targeted and Successful SMS Campaigns
SMS sending campaigns have become an indispensable way for businesses to effectively reach their audience. However, sending messages to invalid, or inactive phone numbers can jeopardize the success of your campaigns.
By verifying the validity of mobile phone numbers, you ensure that your SMS reaches your audience, thereby improving your delivery and open rates. This allows you to precisely target your customers, increase engagement, and promote better responsiveness to your offers and promotions.
2) Time and Money Savings
SMS campaigns can represent a significant investment for a company. Sending messages to invalid numbers results in unnecessary costs and is a clear waste of time. By conducting thorough verification in advance and eliminating inactive or non-existent numbers from your database, you save valuable resources.
Targeting only valid contacts allows you to maximize the return on investment of your SMS campaigns.
3) Optimized Online Reservations
For reservation websites, verifying the validity of phone numbers is also crucial. When users provide incorrect or outdated numbers during their bookings, it can lead to communication issues, cancellations, or missed appointments, negatively impacting your business.
By verifying the validity of provided phone numbers, you can ensure that your customers receive relevant information and booking reminders.
How to Verify the Validity of a Mobile Phone Number?
The HLR Lookup
The HLR (Home Location Register) is a central database owned by a mobile telephony network, containing SIM card information of subscribers using that same network (phone number, number location, etc.). Each operator has an HLR.
The HLR Lookup service allows you to access this information in real-time, thus verifying if a mobile phone number exists and which operator it is linked to. By making a request, you can retain only existing and validated contacts in your databases.
The Reverse Directory
As its name suggests, the reverse directory is a tool that allows you to find the identity of a phone number holder from the number itself. The process is the opposite of the traditional phone directory. A handy service when you have a phone number and want to know who it’s linked to, without having to call the person to ask.
Although the reverse directory isn’t ideal for verifying a long list of numbers, it can be useful if you have just a few to validate. Moreover, this tool can’t provide information for all phone numbers. Some might be hidden or belong to users who chose not to appear in public databases.
In conclusion, verifying the validity of mobile phone numbers is a crucial step before launching your SMS sending campaigns. By relying on solutions like the HLR Lookup or the reverse directory, you can ensure the reliability of your data and optimize the effectiveness of your marketing actions.
