Phone Validation for Dialers

Validation Approaches

Pre-Import Batch Validation

Validate lists before importing to your dialer:

1. Export list from CRM or lead source
2. Upload to VeriRoute Intel batch processor
3. Preview results before paying
4. Download enriched CSV
5. Import only valid numbers to dialer

Best for: Large campaigns, list purchases, periodic data refresh

Real-Time Pre-Dial Validation

Validate each number moments before dialing:

# Dialer integration pseudocode
def before_dial(phone_number):
    result = veriroute_lookup(phone_number, lrn=True)

    if result['lrn']['status'] == 'disconnected':
        return SKIP_AND_FLAG
    elif result['lrn']['line_type'] == 'landline':
        if is_business_hours():
            return SKIP_FOR_LATER  # Call evenings
        else:
            return PROCEED
    else:
        return PROCEED

Best for: High-value contacts, compliance-sensitive campaigns

Hybrid Approach

Most call centers use both:

• Batch for initial list cleaning and periodic refresh
• Real-time for new records and callback numbers

Dialer Integration Patterns

Predictive Dialers

Predictive dialers benefit most from pre-validated lists:

• Algorithm works better with accurate abandon rates
• No wasted over-dialing on invalid numbers
• Better agent utilization predictions

Progressive Dialers

Progressive dialers can use real-time validation:

• Validate while agent wraps previous call
• Skip invalid numbers without affecting pace
• Display enriched data to agent before connect

Power Dialers

Power dialers benefit from both approaches:

• Batch validate for initial list quality
• Real-time check before presenting to agent
• Flag records for list management

Useful Data Fields

Implementation Steps

1. Export and Validate

# Export from dialer to CSV
dialer_export.csv:
phone,first_name,last_name,lead_source
5551234567,John,Smith,website
5559876543,Jane,Doe,trade_show
...

2. Batch Process

# Upload to VeriRoute Intel
# Returns enriched CSV with:
phone,first_name,last_name,lead_source,is_valid,line_type,carrier
5551234567,John,Smith,website,true,wireless,Verizon
5559876543,Jane,Doe,trade_show,false,disconnected,

3. Import Valid Records

# Filter and import
valid_records = [r for r in results if r['is_valid']]
mobile_campaign = [r for r in valid_records if r['line_type'] == 'wireless']
landline_campaign = [r for r in valid_records if r['line_type'] == 'landline']

Best Practices

1. Validate before import — Don't pollute your dialer with bad data
2. Store validation date — Track when records were last checked
3. Re-validate periodically — Numbers change status over time
4. Segment by line type — Different calling strategies
5. Flag disconnected — Don't delete, flag for suppression
