Confidence Score
The confidence score (0-100) indicates how reliable our analysis is based on available data and validation checks.
📈 Score Ranges
Score Range | Confidence Level | Description | Recommendation |
---|---|---|---|
80-100 | High Confidence | Comprehensive data available, all checks passed | Safe to use for business purposes |
60-79 | Good Confidence | Most data available, minor uncertainties | Generally reliable, verify if critical |
40-59 | Moderate Confidence | Some data gaps, mixed validation results | Use with caution, additional verification recommended |
0-39 | Low Confidence | Limited data, multiple validation failures | High risk, avoid for important communications |
🧮 How It's Calculated
The confidence score is calculated based on multiple factors:
- Format Validation (30 points): Whether the number follows correct formatting standards
- Carrier Detection (20 points): Successfully identifying the service provider
- Geographic Data (15 points): Availability of location information
- Timezone Information (10 points): Successful timezone identification
- Social Media Presence (Variable): Finding associated social accounts
- Data Consistency (Variable): How well different data sources agree
Common Issues & Solutions
❌ Invalid Phone Numbers
Common Causes:
- Missing or incorrect country code
- Extra digits or characters in the number
- Number format not recognized by our system
- Disconnected or deactivated number
Solutions:
- Try adding the country code (e.g., +1 for US numbers)
- Remove any spaces, dashes, or parentheses
- Verify the number with the original source
- Check if the number is still active
📡 Carrier Detection Issues
Common Causes:
- Number porting between carriers
- Virtual or VoIP numbers
- International numbers with limited data
- Recently activated numbers
Solutions:

🕐 Timezone Accuracy
Common Causes:
- Mobile numbers that have moved locations
- VoIP numbers without geographic ties
- Numbers from regions with multiple timezones
Solutions:
- Use the country-level timezone as a fallback
- Verify timezone with the number owner
- Consider that mobile numbers may not reflect current location
🔍 Social Media & Reverse Lookup Limitations
Understanding Limitations:
- Privacy settings may hide phone number associations
- Not all users link phone numbers to social accounts
