How to Detect Valid Or Inactive Phone Numbers

Phone verification is an indispensable tool for preventing fraud and maximizing ROI on marketing campaigns that rely on SMS or phone-based outreach. For example, retail stores can verify customer phone numbers to ensure that flash sale notifications and loyalty program messages are being sent to active mobile users. This improves campaign engagement and ROI instantly. It can also help businesses comply with regulations like TCPA and DNC by filtering out risky or restricted contacts before sending any message.
It’s essential to detect invalid or inactive phone numbers and remove them from your database as soon as they become outdated. Inaccurate data can create communication breakdowns, cost you time and money, and result in compliance violations if not addressed quickly.
How to Detect Deactivated or Fake Phone Numbers
Detecting and eliminating invalid phone numbers saves you time, money and resources by helping you focus on your real customers. It prevents your messaging from reaching inactive or disconnected numbers and increases customer retention rates. In addition, it helps you avoid regulatory fines and penalties for violating the TCPA and DNC laws.
A phone number validation service checks the validity of a number by cross-referencing it with multiple carrier databases, pinging the number on the network, and identifying its status. It also shares other information tied to the number, including type (mobile, landline, or VoIP), country of origin, and whether it’s in a DNC list or known litigator pool.
Integrating a phone validation service into your business processes is simple and can be done at the point of data entry in your website, PoS, CRM, or call center system. It can automatically standardize and validate a single phone number or cleanse entire lists on a regular basis, saving you time in the long run.
