## Abstract

This document amends the rules implementing the Telephone Consumer Protection Act (TCPA) to establish a limited safe harbor period from the prohibition on placing autodialed or prerecorded message calls to wireless numbers that have been recently ported from wireline to wireless service. This document also amends our existing safe harbor rules for the national do-not-call registry so that telemarketers are required to access the do-not-call list no more than 31 days prior to making a telemarketing call.
