How to Search for a Mobile Number Owner

By Nakia Jackson

What do you do if you need to track someone down, and you only have a mobile number? With a landline, you'd have the area code and exchange to narrow it down, and telephone directories such as the white pages. These things often don't help with mobile phones, as mobile phones are not listed in most directories. An area code and exchange can indicate where the contract was initiated, but not where the person might be now. But just as technology can make it possible to take a phone from New York to New Mexico while using it, it's also possible to track down someone by his mobile phone number.

Calling the Mobile Number in Question

Step 1

Call the number in question. Introduce yourself and state your purpose for calling if someone answers. Ask for the mobile number owner.

Step 2

Leave a message including your contact information if no one answers the phone. Give the person at least one day to respond.

Step 3

Establish the identity of the person you're seeking when she contacts you. State the purpose of your inquiry, and conduct the desired business.

Advertise Locally

Step 1

Place an advertisement with online community message boards like Craig's List. List the mobile number, minus the last two digits, in the title. Ask those who email you to give you the last two digits of the number to confirm that they know the full number. Include contact information, such as an email address, in the advertisement. Clearly state the purpose of your inquiry in the advertisement.

Step 2

Wait a few days for replies. Ask respondents to call you from the mobile number in question or ask permission to contact them at that mobile number.

Step 3

Establish or confirm the identity of the mobile number owner when you speak on the phone.

Reverse Look-up

Step 1

Use a reverse look-up service that specializes in mobile numbers. Find one that offers initial or "teaser" information about the number that seems likely to be accurate.

Step 2

Subscribe to the site to gain access to the complete record.

Step 3

Call the number and ask for the name listed in the reverse look-up results. Try email or postal mail if the necessary information is included in the results. Confirm the identity of the mobile phone owner.

Tips & Warnings

  • Give the owner time to respond. A few days to a week should be sufficient before moving to the next step.
  • If the owner refuses to respond to any efforts to contact him or her, you may need to abandon your query.
  • For family plans, all numbers may be listed under the same name.
  • Not all reverse look-up services are accurate. You can check a mobile number that you know to test them.
