Does Clay Verify Phone Numbers Against Do Not Call Lists?

Does Clay phone number enrichment first check with the national do not call lists (e.g. https://telemarketing.donotcall.gov/) before returning a response?

Our phone number enrichment services focus on validating phone numbers for accuracy, checking if they are active, and identifying line types (e.g., mobile or landline). We offer various phone enrichment providers like SureConnect, Wiza, BetterContact, and ZoomInfo that help with finding and verifying phone numbers. However, checking against national do not call lists is not part of our standard phone number enrichment process.
