Phone Validator & Real-Time Phone Lookup Tool
A phone validator checks whether a phone number is valid, active, and reachable. RealValidito’s phone lookup tool also shows line type, carrier, and location details in real time. As a result, you can clean your contact data and improve communication before sending messages or making calls.
In addition, you can use our real-time Phone Validator API to automate number checks inside your CRM, website, or app. If you manage large lists, simply upload a CSV file for bulk phone validation.

What Our Phone Validator Does
With RealValidito, you can quickly check whether a phone number is valid or invalid. You can also see if the number is mobile, landline, toll-free, or VoIP. Furthermore, the system provides carrier and region details to help you plan your outreach.
Because accurate phone data improves campaign results, businesses rely on phone lookup tools to remove outdated or incorrect numbers. Therefore, validating numbers before contacting customers reduces errors and increases efficiency.

Why Use RealValidito?
Increase Conversions
Without validation at the point of entry, you risk capturing wrong phone data, which can harm future communication and cost you customers. With our phone validator, you can remove invalid and outdated numbers from your database.
Improve Deliverability
Your message matters. Because RealValidito provides carrier and phone line information, you can decide whether to send SMS or place calls — at the right time and in the right way.
Reduce Messaging Costs
Feeding wrong numbers into auto-dialers or SMS tools leads to poor reach rates and higher expenses. Therefore, validating numbers helps you achieve better reach at a lower cost.
Boost Customer Satisfaction
When your messages reach real, active users, they stay informed throughout their journey — which improves retention and repeat orders.
Integrate Anywhere
Whether numbers are entered by staff or customers, every small mistake can cost big business. Because our Phone Validator API integrates with CRM systems, mobile apps, and websites, you can validate numbers automatically at the point of entry.
Choose the Right Channel
Because our system detects line type, you know whether to send SMS or place a voice call. This ensures better delivery and timing.
