The ultimate guide to phone validation

Sep 7, 2021, 10:59:19 AM Tech and Science

The process of validating phone numbers is known as phone validation. There is a procedure that claims to enhance the quality of a list by correcting formatting errors and adding data points such as country, carrier, and line type, or even requesting explicit user authorization to be reached on a phone number.


Three methods of validation will be discussed in this article. With various data points, each gives a different amount of confirmation. You should ideally be able to pick the correct form of validation for your purposes after going through and evaluating the benefits and drawbacks of each type.


1. Validation of numbers


This is the most thorough and time-consuming stage of validation, with the purpose of ensuring that a phone number has been approved and allocated to a carrier and line type by a particular country's telecom regulator. Not all numerals are used in most nations. In Seychelles, for example, the number +248 2 510 123 is acceptable, but not +248 5 510 123, despite having the same amount of digits.


A valid number is one that has been approved by telecom authorities and has been allocated to a carrier and line type but is not necessarily active at the time of writing.


Points of Information


You can expect to obtain the following data points after verifying a phone number:


  • Valid- True indicates that the phone number has been authorized and allocated to a carrier.
  • Format- The phone number should be formatted in a normal international or local format.
  • The line type- is determined by the telecom authority. Mobile, landline, VoIP, toll-free, and satellite are examples of line types.
  • Region- A telephone number is given to a certain nation region.
  • Carrier (original)- the name of the carrier to which the phone number is issued.


2. Validation of the Network


Without calling the phone number directly, network validation entails contacting the carrier to enquire about the current status of the phone number. When you connect directly to the phone network, you may find out if the number is active, the current carrier's name, and the roaming status. The coverage rate is a key disadvantage of this approach. Only mobile numbers are accepted by fewer than 85% of global carriers.


Points of Information


  • Active- If the number is allocated and active, this value is true.
  • Original Carrier- The initial carrier is the moniker given by the telecom authorities to the first network.
  • Ported carrier- If a carrier has been ported, this is the name of the carrier.
  • Roaming carrier- If roaming, the name of the roaming carrier.


3. Validation by users


The next step in the validation process is to ensure that the phone is available to receive text or voice messages and that the user who gave a phone number can be reached at that number. This level of validation is accomplished by delivering a numeric code to the phone number through voice or text message and requesting that the owner return the code via the web or a mobile app. A user's express agreement to be contacted on that number is shown by the returned code.


Conclusion


You've undoubtedly realized that no single validation technique is ideal. In order to accomplish the desired result, one, two, or perhaps all three approaches may be required, depending on the use case.


It's a no-brainer to validate numbers. This validation type may be used in any solution to eliminate illegal numbers before moving on to the following two stages of data collection.
