Skip tracing

How to remove bad numbers from your skip trace list

Removing bad numbers from your skip trace list starts with clear definitions of what "bad" means for your operation, then creating a system to flag and prune those contacts. This process ensures your outreach is efficient, saving time and resources from dead ends.

What counts as a "bad" number?

Before you can remove bad numbers, you need to define what makes a number unusable for your specific outreach strategy. A number might be considered "bad" if it consistently leads to a wrong person, is disconnected, generates no answer after multiple attempts, or is explicitly identified as a Do Not Call (DNC) number. Each of these situations dictates a different removal or re-evaluation process.

For some, a number is bad if it's clearly not the homeowner. For others, it's bad if the homeowner asks not to be contacted again. Having a consistent definition across your team prevents confusion and ensures everyone is working from the same playbook.

Implement a system for flagging bad numbers

Use your CRM, dialer, or even a detailed spreadsheet to consistently flag numbers that meet your "bad" criteria. This might involve creating specific tags like "Wrong #", "Disconnected", "DNC", or "No Answer 10+". The important part is that every team member follows the same tagging protocol.

Consistency in flagging allows you to easily filter and review these numbers later. Without a clear system, bad numbers will linger in your lists, wasting time and potentially leading to compliance issues if you continue to contact DNC individuals.

When to remove a number permanently

A number should be permanently removed from active outreach lists when it's confirmed as a DNC request or consistently leads to a wrong person. For DNC requests, honor them immediately and ensure the number is on your internal suppression list, as compliance is paramount. For wrong numbers, remove that specific number from the current owner's profile.

Disconnected numbers can also be removed immediately, as there's no way to reach the intended contact. If a number consistently gets no answer after a predetermined number of attempts (e.g., 10-15 calls over several weeks), it might be better to remove it and focus efforts elsewhere, or consider a fresh skip trace for that owner if the lead is still valuable.

Dealing with disconnected or inactive numbers

Disconnected numbers are dead ends and should be removed from your active dialing lists. There's no value in calling a number that doesn't connect. If the lead itself is high-quality, you might consider re-skip tracing the property owner to find alternative contact information, but the specific disconnected number should be archived.

Keep an eye on trends with disconnected numbers from specific skip trace batches. If you see a high percentage, it might indicate an issue with the data age or quality from that particular source. This helps you refine your lead acquisition strategy over time.

Handling "wrong person" responses

When you reach someone who says you have the wrong number for the property owner, flag that specific number as "Wrong Person" for that owner. You should not continue to call that number. However, you might still have other numbers for the owner from the skip trace that could be valid.

If you only had one number for him or her and it was a wrong person, archive that lead or consider a new skip trace for the owner if the property still looks promising. The goal is to clean your data without prematurely discarding a potentially good lead.

Automating removal and suppression

Many CRMs and dialers allow for automated suppression lists. Once a number is tagged as DNC or disconnected, it can automatically be moved to a list that prevents future outreach. This is a critical feature for maintaining compliance and efficiency, especially as your lead volume grows. This is not legal advice, so you should consult with your own counsel to ensure you are compliant with all applicable laws.

Review these suppression lists periodically to ensure accuracy and to understand the volume of numbers you are removing. A high volume of DNC requests, for instance, might signal a need to adjust your initial outreach messaging or targeting.

Questions people ask

What if a number is just always busy?

An always busy number might be disconnected or an inactive line. After a few attempts spread out over time, if it remains busy, treat it like a disconnected number and remove it from your active list or re-skip trace the owner.

Should I ever re-add a removed number?

Generally, no, especially if it was a DNC request or confirmed wrong number. If you re-skip trace an owner and get a new number that happens to be one you previously removed for another reason (like "no answer"), you can try it, but be cautious with DNC numbers.

How often should I review my bad number list?

Review your bad number flags weekly or monthly to ensure they are being handled correctly and moved to suppression lists. This helps keep your data clean and prevents your team from wasting time on dead ends.
