Phone validation online is a term used to describe the process of verifying phone numbers. Correcting formatting problems and adding data points such as country, carrier, and line type are some of the procedures that promise to improve the quality of a list. Other procedures require explicit user permission to be contacted on a phone number.
In this post, we’ll go through three different validation techniques. Each piece of information adds a different level of confirmation to the picture. After weighing the advantages and disadvantages of each kind of validation, you should be able to choose the one that is most suited to your needs.
Numbers are checked for accuracy.
In order to ensure that a phone number has been authorized and assigned to a carrier and line type by a certain country’s telecom authority, this is the most comprehensive and time-consuming step of validation. Most countries do not utilize all of the numbers. Despite having the same number of digits, in Seychelles, the number +248 2 510 123 is legal but not +248 5 510 123.
Unactivated numbers authorized by telecom authorities and assigned to a carrier and line type are valid. Active numbers are those that are currently in use.
Factors to Consider
After you’ve verified a phone number, you’ll get the following information:
Valid: As long as it says “Valid,” it means the number has been approved and assigned to a service provider.
International or local format should be used for the phone number’s format.
Type of line. The telecom authority determines the line type. Line types include mobile, landline, VoIP, toll-free, and satellite.
Region- A certain country region has its own phone number.
Originally assigned to the phone number’s issuing provider.
The Network’s Validation
Network validation involves contacting the carrier to find out the current status of the phone number without calling it directly. For example, by connecting to a telephone network directly, you may learn if a phone number is operational, learn who the current carrier is, and learn whether or not you’re currently roaming. This strategy’s low coverage rate is by far its most serious flaw. Fewer than 85% of worldwide carriers allow just mobile numbers.
Factors to Consider
Active: This value is true if the number has been assigned and is currently in use.
Original Carrier: The first network was dubbed the first carrier by the telecom authorities.
Ported carrier: The name of a carrier that has been ported is known as the ported carrier by this term.
Roaming carrier: In the event, you’re traveling, provide the name of your roaming carrier here.
Users’ verification
You must now make sure that your phone is capable of receiving SMS or audio messages and that the person who provided a phone number has access to it. In this step, a numeric code is sent to the phone number by voice or text message, and the owner is asked to return the code via the internet or a mobile app. The returned code reveals whether or not the user has agreed to be contacted at that phone number.
Conclusion
You’ve probably come to the conclusion that there isn’t a single best validation method. One, two, or perhaps all three methods may be needed depending on the use case to get the desired outcome.
Number validation is a no-brainer. Prior to going on to the next two phases of data gathering, this verification type may be utilized in any solution to remove any unlawful numbers.
