The Phone Validator helps you check if a phone number is valid, reachable, and correctly formatted saving you time and ensuring cleaner outreach data.
Whether you're verifying numbers one-by-one or in bulk, Tomba delivers real-time validation.
🔍 How It Works
Tomba runs a series of checks to ensure the accuracy and reliability of each phone number you input:
Format Check – Verifies if the phone number follows international standards (E.164).
Carrier Lookup – Identifies the network provider.
Line Type Detection – Tells you if it’s a mobile, landline, VoIP, or toll-free number.
Reachability Test – Confirms if the number is active and can receive calls.
Country Detection – Detects the country and region based on the phone prefix.
What You’ll Get
Each phone number validated will return:
Country & region
Carrier (e.g., AT&T, Orange)
Line type (mobile, landline, VoIP, etc.)
