Phone number validation software

What is phone validation and how can it help your business?

Phone number validation is the process of checking if a phone number is accurate. It lets you find out if the phone number you have for a business contact or customer is active and able to receive calls.

Validating phone numbers helps your business in several ways:

  • Customer satisfaction: Having the right phone number for a customer lets you contact them when it’s most relevant. Whether you want to let them know about a new promotion or an update to their order, your customers will be happy you’re keeping in touch.
  • Employee efficiency: The less time your employees spend calling inactive lines or wrong numbers, the more time they can spend connecting with real customers. Verification also removes the need to manually update or delete inaccurate numbers.
  • Regulatory compliance: You need to follow certain regulations and rules when telemarketing or using text message marketing. Verifying phone numbers helps you comply with these regulations.
  • Effective marketing: Our phone validation tools give the information you need about the phone number, including whether it’s linked to a mobile phone or landline. This makes it easier to decide what type of marketing approach you should use for that customer.

How does phone validation work?

Our advanced phone verification uses data from approximately 1,500 telecommunication providers in over 200 countries and territories to deliver accurate, fast results.

The validation process works by running the phone number through our extensive database. Experian phone verification software finds the number and checks if it’s active. The software also collects information like phone type and network provider. To make sure the phone number is receiving calls, our software sends a test message to the phone, which is not visible to the phone’s owner.

We can even cleanse phone numbers at point-of-entry, so you can be sure they’re valid before they enter your database. By using our phone verification tool, you can immediately see whether a phone number is valid, and eliminate inaccurate data collection.
