Skip tracing

Which skip trace number to call first for a single owner

When your skip trace returns multiple phone numbers for the same motivated seller, you need a strategy to prioritize which one to call first. Focusing on the most likely contact number can save you time and increase your chances of connecting efficiently. This typically means prioritizing mobile numbers over landlines.

Mobile numbers are usually your best bet

Most people today primarily use their mobile phones. This means a mobile number from your skip trace data is almost always the best place to start. People are more likely to answer or return a call to their cell than a landline.

Mobile numbers are also more portable. Even if someone moves, he or she often keeps the same cell number, making it a more reliable long-term contact point.

If you have multiple mobile numbers, you will need a further prioritization strategy, but always aim for a mobile first.

Prioritize direct vs. associated mobiles

Some skip trace results might differentiate between a primary mobile number directly associated with the owner and other mobile numbers that are merely 'associated' (perhaps a family member's or an old work number). Always go for the direct association first.

If the data does not specify, look for clues like how recently the number was updated or if it is listed as a 'home phone' versus 'mobile.'

If you have two equally strong mobile numbers, pick one and stick with it for your initial attempts. Do not call both simultaneously or too close together, as this can seem aggressive.

Landlines are secondary, but still useful

Landlines generally have a lower answer rate than mobile numbers, especially for younger or more transient sellers. However, for older sellers, or those who have lived in the same property for a very long time, a landline can still be a good point of contact.

If your skip trace only returns a landline, or if your attempts on mobile numbers have failed, then a landline becomes your next best option. Do not discard them entirely.

Remember that landlines are often tied directly to the property address. This can be a verification point in itself.

Business numbers: proceed with caution

Sometimes a skip trace returns a business number. These should be approached with more care. Calling a seller at his or her place of work might be seen as intrusive or unprofessional.

If it is the only number, you might try a polite, brief call to introduce yourself and ask if there is a better time or number to reach him or her about his or her property. Be prepared to be asked to call back or hang up.

Use a business number as a last resort, after exhausting personal mobile and landline options. Respect his or her professional boundaries.

Develop a calling cadence for multiple numbers

Once you have a prioritized list, develop a calling cadence. Start with the highest priority mobile number. If no answer, leave a voicemail if appropriate. Wait a day or two, then try again.

If after 2-3 attempts on the primary mobile you get no traction, move to the secondary mobile or the landline. Do not exhaust all attempts on one number before moving to the next.

Keep notes in your CRM about which numbers you have called, when, and the outcome. This prevents redundant calls and helps you track your efforts. For information on what a skip trace actually returns, check out /learn/what-a-skip-trace-actually-returns.

When to re-skip trace or use other methods

If you have exhausted all provided phone numbers and still cannot reach the seller, it might be time to consider a fresh skip trace. Data gets stale, and new numbers emerge.

Alternatively, if phone numbers are consistently bad, consider other outreach methods. Email, if provided, or even direct mail can be effective, though usually slower.

The goal is always to make contact, so be flexible in your approach if your initial phone prioritization is not yielding results. Sometimes, you just need a better list, and knowing when to find /compare/skip-tracing-vs-done-for-you-leads can help.

Questions people ask

Is it okay to call all the numbers at once from a skip trace?

No, that's usually not a good idea. It can come across as spammy or even harassing. Prioritize one number, make a few attempts, and then move to the next if you're not getting through. Keep it systematic.

What if the mobile number is a 'spam risk' according to my phone?

If your phone flags a number as spam, it's a judgment call. It might be an outdated number, or it might be a number that has been used for marketing by others. You can try calling it, but be prepared for a lower answer rate or a frustrated seller. Sometimes it's better to try a different number if you have one.

Should I leave a voicemail on every number?

No. Leave a clear, concise voicemail on the first attempt at a primary number. If you keep getting voicemail on different numbers for the same person, you don't need to leave multiple messages. One good voicemail is usually enough to introduce yourself and invite a call back.
