A active phone number check is considered active when it can be reached and used to receive calls, texts or other communication. Inactive numbers cannot be called and are usually met with dial tones or messages stating the number is not in service. Active numbers are a critical component of your business’s reach and should be cleaned regularly to ensure proper engagement rates.

The most common way inactive numbers enter databases is through human error during data fill up, such as when a customer or applicant provides a number online while shopping for goods, signing up for services or creating a profile on an organization’s website. In addition, thousands of phone numbers are resold or disconnected every day and businesses have to manually clean their lists to ensure that only valid, reachable contacts are used for business outreach, risk scoring and other important functions.
