When using the Identity Match package in Lookup API, you might get two distinct responses when data is not available: one is error code 60003: End User Data is Not Available, and the other is a "no_data_available" value for a specific response property. Here's the difference between those two:

Error Code 60003 indicates a complete lack of information for the provided phone number. It could be due to the number not existing in our data sources or an input error.

In contrast, "no_data_available" means the phone number is recognized, but there's no data for the specific response property you requested. It's essential to recognize these differences to troubleshoot effectively and access the information you need. Verify the phone number's accuracy for error code 60003, while for "no_data_available," consider the data from other properties to evaluate level of match.
