We don't have specific accuracy comparisons for Apollo's phone/mobile enrichment versus other providers. However, our waterfall feature can significantly improve data coverage and quality across multiple providers. We often double or triple data coverage rates at a fraction of the cost compared to single-provider solutions. By using multiple data sources and waterfalling them, we can maximize the accuracy and completeness of contact information, including phone numbers. If you need more detailed information, you can request to speak with a human agent for personalized assistance.
