Quickly say yes to good customers while being equipped to detect even the most sophisticated fraud

Today, mobility is everything and being able to make instant but informed decisions can mean the difference between just reaching sales targets and exceeding them. With fraud and loan declines on the rise, the used car market faces a myriad of challenges during vehicle transactions. So how do you differentiate between good and more risky customers and still make profitable and safe trading decisions? With TransUnion 1Check you get access to a robust suite of solutions that delivers comprehensive vehicle information instantly and enables you to make more actionable, less risky decisions. To provide a more complete and insightful view of the vehicle trading transaction, we’ve partnered with TransUnion Credit Bureau to enable awareness of the customer’s credit standing.

TransUnion’s extensive database of over 19 million consumer records and the TransUnion Auto database—the largest database of vehicle manufacturers, financing and valuation records in South Africa—are at the heart of the app, where real-time information provides motor dealers with the ability to reduce risk while increasing transaction turn-around times and customer satisfaction.

TransUnion 1Check is an easy-to-use app that delivers vehicle and customer information in real-time enabling dealers to make fully-informed, on-the-spot decisions.

Quick Credit

Assists dealers by affording them reference to the credit standing indicator of a consumer. Through this, the dealer is able to discuss the credit standing indicator with the consumer in determining whether or not to commence lengthy sales negotiations on a vehicle for which a consumer may, or may not, be able to obtain financing.

Test Drive

Utilises TransUnion’s Fraud Prevention Model (FPM) to enable dealers to evaluate the level of risk associated with a potential customer prior to entering into a sales negotiation, or even before allowing a customer to take a vehicle on a test drive.

Historical Report

Get the precise value of a specific vehicle at any point in time – both month and year.

Vehicle Verifications

Get extensive manufacturer information, SAPS interest, Datadot and mileage.

Vehicle Valuations

Access the latest trade and retail valuations for vehicles.

Stock Loader

Easily upload and manage vehicle stock and have an instant, up-to-date view of your dealership’s greatest assets.


Combine multiple products offered via our app, giving you quick and easy access to a single, downloadable report.

Digital Dealers Guide

TransUnion has launched the Digital Dealers Guide, a digital platform to change the way people buy, sell, finance and even insure cars. More than 55 years ago, it led to the creation of TransUnion’s first Autodealer’s Guide. Today, the new and improved digital dealers guide is available to all current users of the printed guide and provides an almost real-time view into a dynamic market. This electronic version of the Autodealer’s Guide will empower the auto industry to take the next step towards digital transformation.

The digitisation of the Autodealer’s Guide means that available values will increase to 224 brands, covering a total of over 2,839 model ranges with 14,972 variants. One benefit of this is that estimated values can be generated for vehicles with low volume sales, which currently covers around 30% of the vehicle market. An upcoming feature will also provide values of a new vehicle within its first 12 months of being sold, which has not been available traditionally.

Users need not worry about high data costs, lack of signal or bad connectivity with Digital Dealers Guide, because there is also a complete offline version available. The digital guide has been designed with customers in mind, in that it can be used wherever, whenever, in a seamless, user-friendly fashion.

With these benefits, TransUnion believes the Digital Dealers Guide will be a tremendous driving force for good in the automotive and related industries, empowering auto dealers to uplift the entire value chain with a seamless flow of data between all parties.
