Validate and Verify Phone Numbers

Avoid disconnects and wrong numbers by using TowerData's telephone validation service to identify bad phone numbers on your list before you start calling. Our Premium Phone Database receives over two million phone number changes per day from telecommunication companies, and we can make sure your records are accurate and up-to-date.

By taking advantage of our full coverage, timely data, and extreme accuracy, your telemarketing efforts will achieve greater efficiency and results, and you won't be frustrated by dialing disconnected numbers.

You can also prevent invalid phone numbers from getting on your list in the first place by using TowerData's Real-Time Phone Validation service at the point-of-entry.

Phone Verification only provides a flag indicating whether the number is connected or not. Use Reverse Phone Append to verify and obtain the name and address we have on file for a phone number.

To replace any invalid numbers and fill in any gaps in your database, use our phone append service in conjunction with phone verification. Contact us to keep your list clean and up-to-date!
