Understanding skip trace data output

A good skip trace will return more than just a list of phone numbers. It often includes details like the phone type (mobile, landline, VoIP), the carrier, a confidence score, and sometimes a 'last seen' or 'date associated' field. Review all of this information.

Different data vendors present this information in various ways, but the core idea is to give you context for each number. The more data points you have, the better equipped you are to make an informed decision about which number to try first.

Prioritizing based on data freshness

The most recent date associated with a phone number is often the best indicator of its current relevance. A mobile number that was 'last seen' in the last 6-12 months is generally more reliable than one from several years ago. Prioritize numbers with the newest dates.

If you have multiple mobile numbers, and one has a significantly more recent 'last updated' or 'date associated' field, that is usually your strongest candidate for the primary contact. This simple rule saves you from calling disconnected lines.

Considering the phone type

For direct outreach, mobile numbers are almost always preferred over landlines. Sellers are far more likely to answer or respond to a text message on a mobile phone. Landlines are often ignored, or might belong to an outdated household setup. Focus on mobiles first.

If your skip trace provides a 'confidence score' or 'type' indicating a strong likelihood of it being a current mobile number, move that to the top of your list. Some numbers might be VoIP, which can be less reliable for initial contact attempts.

Looking for "owner" or "primary" indicators

Some advanced skip tracing services or data vendors will flag certain numbers as the 'owner's primary mobile' or have a similar indicator. If your data includes this, it is a strong signal to prioritize that specific number. These flags are based on extensive data aggregation and analysis.

Treat these indicators as highly valuable. They suggest that the data provider has identified this number as the most consistently associated with the individual you are trying to reach. This can save you from guessing.

The strategy for multiple good numbers

If you have two or three mobile numbers that all look promising (recent, good type), start with the one with the highest confidence score or most recent date. If you're doing text outreach, send a text first, then wait for a response. If no response, try a call after a reasonable delay.

Do not bombard the seller by contacting all numbers simultaneously. This can be perceived as aggressive and might lead to him or her blocking all your attempts. One contact method per number, starting with the best candidate, is a more effective approach.

When to use a secondary or tertiary number

If your initial attempts on the primary mobile number fail to get a response after a few days, then it is reasonable to try the next best mobile number from your skip trace results. Again, prioritize by freshness and confidence. You might rotate between texting and calling.

Give each number a fair chance before moving to the next. Remember, it is a follow-up game. A seller might not answer the first time but could pick up on a different number or respond to a text a few days later. Patience is key.

Questions people ask

Should I text or call the primary number first?

For motivated seller leads, a text message is often a good first approach. It is less intrusive and allows the seller to respond at his or her convenience. If no reply after a day or two, then consider a call.

What if all mobile numbers are old?

If all mobile numbers are significantly outdated, consider re-skipping the property or using a different data vendor if available. Sometimes, even older numbers can connect, but your success rate will be lower.

Is it okay to try all the numbers at once?

No, it is not advisable to try all numbers at once. This can be overwhelming for the seller and may lead to a negative impression or him or her blocking your attempts. Approach systematically, one number at a time, with appropriate spacing.
