HLR Lookup — High-Quality Database Cleaning for Deactivated Numbers

Every promotional SMS represents an investment in the success and development of a business. Companies utilize databases bought from providers to send these messages. Over time, some numbers become inactive, making it pointless to send commercials to them.

To avoid wasting money, the client base should undergo regular checks. The HLR Lookup service, which identifies deactivated mobile numbers, can assist with this.

When Should I Update the Database?

You should conduct the first check immediately after purchasing an archive because it may already contain errors. There are several reasons for this:

  • an outdated database;
  • mistakes during data collection;
  • incorrect data entry;
  • accidental or intentional addition of fake numbers (e.g., to enhance the database's appearance);
  • duplication of information.

To ascertain the numbers' current validity, the HLR Lookup service sends a request to mobile operators for each number. The program checks the information and indicates whether it is up-to-date, whether the subscriber is roaming, or has changed mobile operators. Unnecessary data is sifted out, necessary data is structured, and the company can then plan its marketing strategy based on the actual database.

How Often Should You Check the Archive via HLR Lookup?

We recommend updating the database at least twice a year. These tips will help you determine exactly when to do it:

  • Database update frequency: The archive should be checked more often if you continually collect leads and make changes by adding new contacts. Timely reconciliation will help detect errors and deactivate numbers promptly.
  • High requirements for information relevance: The database should be checked more often if your work requires maximum accuracy (e.g., for regular analytics). This reduces the likelihood of errors due to outdated or incorrect data.
  • Budget considerations: Checking via HLR Lookup is a paid service, so it should be factored into costs in advance. If resources are limited and you don't work with the database very actively, you can check numbers less frequently.
  • Business needs: Some activities, such as those related to financial transactions, require regular data verification to ensure the right level of security. In such cases, reconciliation is needed more frequently than every six months.

To check your database, contact Decision Telecom specialists. We offer a service that easily integrates into CRM via REST API and ready-made SDKs, capable of handling a thousand requests per second.
