Screening a property-owner call list runs as five passes over the file before anyone dials.[1] Two of them are list checks: the National Do Not Call Registry under your own Subscription Account Number, resynchronized at least every 31 days, and the entity-specific do-not-call list you maintain yourself.[3][4] Consent comes next, because prior express written consent naming the number is required before any autodialed or prerecorded call or text message.[4] The last two passes are paid work: a scrub against known-litigator and state do-not-call files, and a query of the FCC's Reassigned Numbers Database.[10][12] Sequence decides more than software, since the TCPA lets a called party recover $500 for each violation and lets a court treble that award for a willful or knowing violation, while the FTC puts civil penalties for a Telemarketing Sales Rule violation at up to $53,088 each.[2][1]
