Methods of Mobile Number Validation
There are several methods to validate mobile numbers, each with its own strengths and weaknesses:
1. Regular Expressions (Regex)
Regex is a popular method for validating mobile numbers. It uses a pattern-matching algorithm to check if the mobile number matches a specific format. However, regex can be complex and may not cover all possible formats.
2. SMS Verification
SMS verification involves sending a verification code to the user’s mobile number. The user must enter the code to complete the validation process. This method is more secure than regex but can be time-consuming and may incur additional costs.

What are the different methods of mobile number validation?
There are several methods of mobile number validation, including SMS verification, voice call verification, and HLR (Home Location Register) lookup. SMS verification involves sending a verification code to the mobile number, which the user must enter to complete the verification process. Voice call verification involves making a voice call to the mobile number, which the user must answer to complete the verification process.
HLR lookup is a more advanced method of mobile number validation, which involves checking the mobile number against the HLR database to verify its authenticity. This method provides more accurate results than SMS and voice call verification, as it checks the mobile number against the actual network database. Other methods of mobile number validation include DND (Do Not Disturb) check and number portability check.
What is HLR lookup and how does it work?
HLR lookup is a method of mobile number validation that involves checking the mobile number against the HLR database to verify its authenticity. The HLR database is a centralized database that stores information about all mobile numbers, including their status, network, and location. When a mobile number is queried, the HLR database returns information about the number, including its status, network, and location.
HLR lookup works by sending a query to the HLR database, which returns information about the mobile number. This information can be used to verify the authenticity of the mobile number and check its status. HLR lookup is a more accurate method of mobile number validation than SMS and voice call verification, as it checks the mobile number against the actual network database.
