Export the list from Connect, then Export to File, with the four phone status fields included. Add a row for every other number you hold on those owners, and note on each row where the number came from. Numbers from an outside skip trace belong here, and so do alternates you bought on the owner profile.
Clean the numbers before you compare them, because both comparisons depend on an exact match. This screen handles US numbers in the North American Numbering Plan. Strip punctuation, spaces and extensions. If a number has eleven digits and starts with 1, drop the 1. Store the result as ten digits of text so a spreadsheet can't reformat it. Anything that still isn't ten digits, an international number included, goes to a separate tab for a person to review.
Then collapse duplicates so each number appears once, and keep every property ID attached to it. An owner with four rentals shows up four times with the same phone. Without the other three IDs, a later stop request gets recorded on one property in PropertyRadar, and the same number can come back through a later export of the other three.
The registry comparison comes next, and it starts with counting area codes. They follow the owners' phones and not the county you searched, so an absentee list from one county includes area codes from wherever those owners live. The FTC's Q&A says data for up to five area codes is free, that files come as flat text or XML sorted by area code, and that you can download once in any 24-hour period. For a few late additions, the registry's Interactive Phone Number Search takes one area code and up to ten numbers at a time. Mark each row Registered or Not registered and write the download date beside it.
Your internal list has to be assembled, because the requests are scattered across the tools your callers use. Merge the numbers marked Do Not Call or Opted Out in PropertyRadar with the DNC list under WAVV Settings. WAVV is the dialer built into PropertyRadar. Add the opt-outs held in any other dialer, CRM or calling vendor, and keep the result as one master file. A request recorded in one system isn't automatically in the others, so a number an owner opted out in one dialer can stay callable in the next until the lists are merged.
Remove every row that matches either list and save what remains as the dial file. Don't make exceptions inside the batch. If you believe a registered number can still be called, on written consent for example, pull it out and have a named person review the seller, the number, the purpose of the call and the channel. That person documents the basis and releases the number in a separate file, so the batch never passes a suppressed number.
Load only the dial file into the dialer. PropertyRadar's phone marketing overview describes a prompt at the start of a WAVV calling session that offers to exclude DNC numbers, and accepting it gives you a second check. If you dial from another tool, import the master suppression file into that dialer before the first call.
You can also keep suppressed owners out of future lists inside PropertyRadar. Put their properties on a static list and add it as an Exclude List criterion on each new search. The criteria glossary says Exclude List accepts static lists and monitored dynamic lists. It works on properties, so the phone match in your file still has to catch an owner who reappears through a different property.
Passing both comparisons clears a number to dial. It doesn't confirm that the number reaches the owner, which is part of what to verify before contacting an off-market owner.
