+Screen state do-not-call registries (38 states plus DC) and a national complainer list at no extra credit. Each check is its own flag:
 
 ```js
-const result = await client.lookup('8182925409', { dncOther: true });
-result.data.dncStateResult;      // "STATE DNC" or ""
-result.data.dncComplainerResult; // "DNC COMPLAINER" or ""

+result.data.dncStateChecked;     // "true" when the state check ran; absent for the 12 states with no registry data
+result.data.dncStateResult;      // "STATE DNC" on a match, "" otherwise (only when dncStateChecked is "true")
+result.data.dncComplainerChecked; // "true" when the complainer check ran
+result.data.dncComplainerResult; // "DNC COMPLAINER" on a match, "" otherwise
 ```
 
+Read `dncStateChecked` before `dncStateResult`: a number in an uncovered state comes back with neither field, which means not checked, not clear. `"error"` means the check could not complete; treat it as unavailable.
+
+`dncOther: true` still works as a shorthand for both checks, but it is deprecated.

 Some landlines can receive texts. Detect them instead of dropping them (+1 credit, charged only when the number is a landline):
