How to handle wrong numbers from skip tracing

When you get wrong numbers from skip tracing, first verify the original data source and the skip trace vendor's accuracy. Then, remove those bad numbers from your outreach lists immediately to protect your reputation and avoid wasted effort.

Identifying a wrong number call

It is pretty obvious when you dial a number and the person on the other end says, 'You have the wrong number.' Do not argue. Apologize politely and hang up. The goal is to correct your data, not to convince someone they are wrong or to annoy them.

Sometimes you will get a dead number, a disconnected line, or a voicemail box that clearly is not the person you are looking for. Mark these in your CRM or spreadsheet the same way you would a direct 'wrong number' response.

Logging and tracking bad numbers

Every time you get a wrong number, you need a system to log it. In your CRM, create a custom field or a tag like 'Bad Number' or 'Wrong Party'. This allows you to filter these numbers out of future campaigns.

If you are using a spreadsheet, have a column dedicated to call outcomes. Mark the specific phone number as bad, and note the date. This helps you understand the quality of your skip trace data over time.

Removing bad numbers from your lists

This is critical. A bad number should be removed from all active outreach lists associated with that lead. If you have multiple phone numbers for one property or owner, only remove the specific number that was identified as wrong.

Do not just move it to a 'do not call' list if it is definitively a wrong number for your target. It should be purged from your system for that contact entirely. Repeatedly calling wrong numbers wastes time and can hurt your carrier reputation if you are sending texts.

Evaluating your skip trace provider's accuracy

If you are consistently getting a high percentage of wrong numbers from a particular skip trace vendor, it is time to re-evaluate. Track the ratio of good numbers to bad numbers. What percentage are actually connecting to your target seller?

Some level of bad data is unavoidable, but if it is above, say, a hypothetical 15-20% for a given batch, you might need to adjust your expectations or consider a different provider. Remember, paying for skip tracing should yield usable data. You can read about what a skip trace actually returns at /learn/what-a-skip-trace-actually-returns.

Improving data hygiene moving forward

Start with cleaner lists. If your initial property data is old or inaccurate, even the best skip trace will struggle. Ensure your initial lists are as fresh as possible, perhaps from recent tax records or updated public sources.

Consider using multiple skip trace providers for critical lists and cross-referencing the results. While this adds a layer of work, it can significantly improve the accuracy of your phone numbers, especially for high-value leads. Also, understand that mobile numbers are generally more reliable for direct contact than landlines, which often have higher rates of being disconnected or wrong.

Questions people ask

Should I try calling a wrong number again later?

No, if a number is confirmed as wrong, remove it. Calling it again is a waste of time and can annoy the person who received the call. Focus your efforts on verified numbers.

How many wrong numbers are acceptable from a skip trace?

There is no exact rule, but a certain percentage of wrong or disconnected numbers is normal. If you are seeing a hypothetical 20% or more consistently, you might want to review your list quality or skip trace provider.

Does getting wrong numbers hurt my texting campaigns?

Yes, sending texts to disconnected or wrong numbers can negatively impact your sender reputation with carriers, potentially leading to your messages being blocked or filtered. Clean data is crucial for texting.
