Why validate phone numbers?

By validating landline and mobile phone numbers, you ensure that you can contact users who register on your platform. There is no point in investing money in capturing leads if you can’t contact them afterwards. For users you have already recruited you can use phone number validation via files. Know the real number of your active users. Maintain the quality of your database.

With the numbers already verified you can launch voice marketing campaigns to expand your contacts’ data, get feedback or promote and sell new services.

The phone number verification service also allows you to obtain additional phone number information. We can know the country, type of line, operator, portability… All this information allows us to obtain a deeper understanding of the user.

How we validate phone numbers

Getting new contacts is expensive, don’t let a mistake in writing the phone number ruin your investment in recruitment. To check telephone numbers we use the operator’s own network. This allows us to have 100% reliability for mobile numbers and for landline numbers it depends on the country of the number.

Types of telephone verification
HLR LookUP, MNP LOOKUP and SYNTHATICS

We have 3 methods to verify phone numbers. Each provides different levels of information about the verified number.

HLR LookUp Verification

It is the most accurate method of telephone number verification. Allows to know if a number is currently connected to the mobile network. Validate the status and details of mobile numbers in real time. The term “HLR” stands for Home Location Register, a central database containing details of each cell phone subscriber authorized by a GSM network. The HLR search, therefore, is a way to access this information to ensure the validity and availability of a mobile number. This technology offers the highest degree of accuracy, but has the highest verification cost.

MNP LookUP Verification

Mobile Number Portability (MNP) lookup verification is a process used to validate numbers and ensure accurate identification of network providers. The MNP search helps to determine the current operator of a mobile number. Companies use this information to route SMS messages accurately and cost-effectively. MNP verification offers a compromise between the degree of accuracy and the cost of each validation.

Syntactic verification of numbers

Syntactic verification of telephone numbers ensures the accuracy and consistency of telephone numbers. It consists of checking the structure and format of the telephone number to ensure that it conforms to a specific pattern or set of standards. This process helps to identify and correct errors. This type of verification is the most economical, but at the cost of obtaining less information from the verified numbers.

HLP LOOKUP

It offers the highest degree of accuracy. Allows to know if a terminal is currently connected to the network.

FAQ

Our telephone verification service is 100% accurate for mobile numbers since we use the operators’ own network to simulate a call if we are able to establish communication with the user. For landline numbers it depends on the country where the phone number to be verified resides.

Free credits are available for you to test the phone number validation service for free. Just register and you will be able to verify phones individually, via files or API.

The telephone verification service works in real time. On average it takes 1-2 seconds to validate a phone number. The validation of the files depends on the number of records they contain.

We use the telephone network itself to perform the verification process. For mobile numbers we can offer 100% reliability for landline numbers we can also perform a verification but the reliability will depend on the operator managing the number and the country.

Phone verification packs are valid for one year. If a recharge is made before the end of the year, the unused credits are accumulated.

All our communications are encrypted using 256-bit SSL. Your contact information is stored on servers in the European Union and is kept encrypted in accordance with our privacy policy. They are only accessible by one person with access credentials.
