Detecting Invalid or Inactive Phone Numbers

When it comes to ensuring the effectiveness of your business’s marketing and sales outreach, valid contact information is a critical asset. Invalid, fake, or disconnected numbers can lead to a variety of problems including wasted resources, communication breakdowns, and compliance concerns (depending on regional regulations, reaching a ported or inactive number could be considered a violation).

Whether you’re detect invalid or inactive phone numbers for a simple way to validate a single phone number before calling or an API to validate a list in bulk, the ability to quickly and accurately detect invalid or inactive phone numbers can improve your business and help prevent unnecessary costs. Invalid numbers might become disconnected due to changes in service providers, the loss of a mobile phone, or simply being switched to a different line by the subscriber. Other reasons could include a number that is not active or was previously used for DNC registration or fraud.

Verify Emails Before You Hit Send: Campaign Protection Tips

Invalid phone numbers are expensive and frustrating to reach for marketers and business owners alike. They can result in poor response rates, skewed data analysis and a general lack of effectiveness when it comes to reaching current or prospective customers. To avoid this, businesses can use a phone validation service to confirm the status of any number as it is entered during signup or checkout on their websites. This real-time verification process uses a ping of the number with the carrier to determine its validity and provides valuable information such as the type of phone (cell, landline, or VoIP) and recent connectivity.
