Discover the Ideal Phone Validation Plan for You:

Use Phone Validator API for real-time form validation or Bulk Phone Number Validation for lists.

Using a phone validator API at point of entry can identify disconnected numbers before they enter your ecosystem.

There are really only two times that phone data quality matters: at the time of creation and at the time of use.

The quickest way to improve your conversion rates at both of these times is to simply validate the numbers.

What is Phone Validation?

Selecting a provider for phone number validation can be confusing because many services use the terms valid, active, and connected interchangeably. This can make it hard to compare apples to apples when looking for a phone validator.

See the definitions below to help you determine the best phone validation service for your needs:

Connected / Disconnected – The number belongs to someone and is in service / The number is out of service.

RealPhoneValidation’s Phone Validator is the industry’s most accurate phone number validation service. Accessing live telco data, RPV Turbo makes up to 4 inquiries to provide true real-time connected/disconnected dispositions.

Active / Inactive – The number has been assigned to a phone carrier (does not mean the carrier has assigned to a person) / The number has not been assigned to a carrier.

Valid / Invalid – The number complies with the North American Number Plan Association (NANPA) / The number is not compliant with NANPA.

Phone Number Verification – The most common type of phone number verification is to send a code via a call with a recording or text message, which they would enter into a form before continuing.

Four Key Benefits of Phone Number Validation

Enhanced Connectivity: Validating phone numbers ensures you always have updated contact details for effective customer communication through calls or texts.

Regulatory Compliance: By understanding the type of phones you’re contacting, phone number validation helps you adhere to local and federal regulations in telemarketing and text message marketing.

Boosted Efficiency: Verifying phone numbers can accelerate sales and customer service processes, minimizing time spent on inactive or incorrect numbers. Services like RealPhoneValidation’s phone validator streamline this verification.

Improved Messaging Strategy: Validate phone numbers to avoid sending text messages to landlines, making your text message marketing more effective.
