"In the last 12 months more than 80% of downloaded numbers have never been allocated to another project."

What is it?

Sampleworx provides verified and guaranteed household phone number sample to the market research industry in Australia.

Why was it Created?

Many market research agencies and fieldwork companies are currently using outdated systems for the provision of their phone number sample. The result is a high level of invalid numbers (up to 50%) which adds time and cost to a project.

How does it Work?

Sampleworx randomly generates phone numbers, then validates each one before adding them to our database. In this way, you can be assured that you are dialling a potential respondent. Imagine the time and cost savings achieved by dialling over 98% valid numbers.

With such a great repository of up to date phone numbers, we can also offer a completely random and nationwide representative sample.

We have designed this service to be used on a per-project basis. With each new project, you can specify the regions or postcodes you require and the sample will be drawn randomly from the database. Your sample can also be weighted by the population of each region or post code.

Once processed the sample can be downloaded in seconds. The downloaded file is in CSV (Comma Separated Values) format and can be easily uploaded into your phone room.


Sampleworx is an online membership based service. Once a member you simply login, purchase credits, then specify the sample you require. The sample is ready to be downloaded in minutes. It's that easy!

Step 1: Membership Form

Step 2: Purchase Credits

  The Sophisticated technology behind Sampleworx ensures each number is re-validated every 6 months to refresh the sample pool and to maintain the disconnect rate at less than 5%.

Greater coverage of numbers - not just those published - including new exchange areas and VOIP numbers. Our database currently holds millions of phone numbers spread across Australia and each day this rapidly grows towards a full representation of household phone numbers.

  Phone numbers are profiled to ACMA Districts & Zones including a "best guess" postcode.

  The Sampleworx reference portal uses a Google maps overlay for ACMA districts & zones, post codes and LGA’s. SLA’s are coming soon.

  Easy to use and highly functional online self-service acquisition portal. Use anywhere, anytime.

Credits can be used to wash client supplied lists including mobile phone numbers
