The HLR lookup cell phone verification service allows you to validate in real time and with worldwide coverage the veracity of a cell phone number and obtain detailed information about the number.
The verification can be done individually with our Web application, massively through files or automating the whole process with the HLR lookup API.
By verifying cell phone numbers, you ensure that you can communicate with users registered on your platform. Investing in lead acquisition is pointless if you cannot establish contact with them. For already acquired users, you can validate phone numbers through files. This way, you will know the real number of your active users and ensure the quality of your database.
Once the numbers are validated, you can run voice marketing campaigns to expand your contacts’ information, get feedback or promote new services.
The phone number validation service also allows you to obtain additional details such as country, line type, operator and portability. This information gives you a deeper understanding of your users.
The HLR Lookup verification function allows you to determine the validity of a phone number and its current status in a network (active or inactive).
It also provides information such as the MCCMNC (Mobile Country Code and Mobile Network Code), the IMSI (International Mobile Subscriber Identity), details on inter-network portability, roaming status and the corresponding Mobile Switching Center.
This information is obtained by connecting to the telephone operators’ databases and querying the information of a given number.
Number verification through HLR lookup and validation through MNP lookup are two different but complementary processes in the telecommunications field.
While HLR lookup verification focuses on determining the availability and current status of a mobile number, MNP lookup validation focuses on verifying whether a number has been ported to another operator.
Both methods are essential to ensure proper communication with the mobile number.
The HLR lookup check allows you to know whether a number is active, inactive or has been reassigned, which is especially useful for marketing campaigns or for purging contact databases.
MNP lookup validation helps to identify whether a number has been transferred to another operator, which is essential to ensure that calls are routed correctly and serves to verify this, albeit indirectly.
There is a third method based on syntactic verification of the mobile number.
This method checks that the numbering complies with international standards, obtaining the different formats of the verified number, as well as the country and operator.
This method does not guarantee number connectivity.
In summary, although different in their main objectives, both HLR lookup verification and MNP lookup validation are valuable tools for ensuring effective communication with mobile numbers.
Suitable for fixed and cell phones. It only validates the syntax of the number to meet international standards.
Suitable for cell phones where we cannot use the HLR service. Verification is done by IMSI.
Suitable for cell phones. It offers the highest degree of accuracy and is the only one that provides information on number connectivity.
The verification process, also known as Home Location Register (HLR) lookup, is a real-time query that provides up-to-date information on the status of a cell phone number.
The HLR, or Home Location Register, is a database that stores detailed information about all cell phone numbers in a mobile network.
By performing a search in the HLR, you can access the latest information on the status of a specific cell phone number.
By using the operators’ HLR database, our service offers 100% accuracy on mobile numbers that support the HLR service.
HLR lookup verification services are available in almost all countries of the world.
What varies is the degree of information provided by the HLR validation.
Depending on the operator and country, we may not get information about the network connection status.
However, we can still know the IMSI and/or MCCMNC code that helps us to validate the phone number.

When integrating HLR lookup into your verification system, there are some best practices you can follow to maximize verification effectiveness.
First of all, it is important to perform the phone number verification in real time, preferably during the registration or login process.
This helps ensure that phone numbers are valid at the time of verification.
To facilitate the use of phone number verification services, we have created a POSTMAN library where you can see the API calls for both individual phone number verification and bulk phone number verification using files.
Remember that you can find more information in How to use the HLR Lookup API to validate phones where the main API calls and the advantages of validation are explained.
