With three different phone SKUs for phone identity data, we get this question often on which product is the right fit for their business.
To recap quickly:
Reverse Phone API validates a phone number and provides phone metadata, owner name and their demographics, current and historical addresses, and associated people.
Caller Identification API provides an incoming caller’s identity, including phone metadata (carrier, line type, prepaid status, etc.), name, demographics, and current address.
Smart CNAM API validates a phone number and provides the name of the person or business to which it belongs.
In terms of the data dictionary, here is the difference:
| Attribute | Reverse Phone API | Caller Identification API | Smart CNAM API |
| Phone Metadata | ✓ | ✓ | |
| Subscriber/Associated Person or Business Name | ✓ | ✓ (Single name) | ✓ (Single name) |
| Demographics | ✓ | ✓ | |
| Current Address | ✓ | ✓ (Single address) | |
| Historical Address | ✓ | ||
| Associated People | ✓ |
When to use which phone SKU:
| Use Case | Reverse Phone API | Caller Identification API | Smart CNAM API |
| Lead Enrichment | ✓ | ||
| Lead Verification | ✓ | ||
| Lead Analytics | ✓ | ||
| Fraud Detection | ✓ | ||
| CRM Update/Identity Resolution | ✓ | ||
| Screen Pop Caller Identification | ✓ | ||
| Call Routing | ✓ | ||
| CNAM Caller Identification | ✓ |
Please note that there might also be pricing considerations. Reverse Phone API and Caller Identification API start at $0.07/query, while Smart CNAM API, which just provides a single name associated with the phone, starts at $0.015/query.
