A number checker online is a service that provides real-time information about a phone number to verify its availability. This information can include the phone carrier, subscriber name, line type and location. Additionally, some tools can also provide unique risk scoring that identifies high-risk phone numbers that may be associated with fraudulent activity.

Using this information, service providers can avoid routing messaging or voice traffic to invalid numbers, saving termination costs. For SMS campaigns, this can be especially important when targeting international or mobile numbers where the cost of a message is more expensive.

Number Checker Online: Reliable Verification Tools

Another advantage of this type of tool is that it can ping a number to confirm its availability. For example, Textmagic, a business text messaging provider, provides this feature for free to its users. The tool uses Google’s public database to verify a number’s format and performs a live ping to check whether the number is active or not.

Other number checker online services use real-time carrier data to validate a phone number, providing information such as its active status and location. These tools can also ping a phone number to identify the person or company that owns it. This information can help prevent fraud and identity theft by revealing the names of people who have been linked to specific phone numbers. These sites can also reveal familial connections and other personal information about the owner of a number.
