According to the Telemarketing Sales Rule (TSR) and the National Do Not Call Registry requirements, nonexempt telemarketing entities must check their call lists against the National Do Not Call Registry at least every 31 days. This ensures that they do not call individuals who have opted out of receiving telemarketing calls.

The 31-day rule helps ensure compliance and reduces the likelihood of violating the Do Not Call regulations.
