Built-in protection with the International Security Register

The unique 7 digit security code and 24/7 contact telephone number of the International Security Register (ISR) permanently etched into the windows of your Fiat are the equivalent of fingerprints.

Once your vehicle details are registered with the ISR the identity and Police National Computer stolen vehicle status becomes immediately verifiable with just one phone call to the Register.

This not only provides a massive deterrent to vehicle theft and combats modern vehicle crime such as cloning, but also greatly improves the rate of recovery of stolen vehicles.

By ‘devaluing’ your Fiat to organised criminals by putting them at risk of detection, your vehicle is statistically 50% less likely to be stolen than a like vehicle that is not marked and registered with the ISR. Similarly a marked and registered vehicle is 45% more likely to be recovered if stolen.*

What is the International Security Register?

The ISR is a highly secure and confidential database, owned and operated exclusively by Retainagroup Ltd, the UK’s leading supplier of security marking and registration systems to the Motor Industry for over 36 years.

The 24/7 manned ISR contact line (no answer machines or recorded messages!) provides an all year round, immediate verification service for the public, police, motor dealers etc.

How does the system operate?

The system is based upon simple but highly effective procedures – Marking, Registration and Verification.

  1. The windows of your Fiat are etched with an overtly visible, permanent, unique security code and the 24/7 ISR contact telephone number.
  2. Immediate verification of your Fiat’s identity can be provided at any time of day or night by just one call to the ISR 24/7 contact telephone number.

What is the purpose of registering my vehicle’s mileage?

It protects buyers from purchasing used vehicles which have had their mileage falsified. As criminals cannot profit by tampering with a protected vehicle’s mileage it creates another deterrent against theft.

What other information is held on the ISR?

The security codes for your vehicle’s key/immobiliser may be recorded on the Register. To protect you against criminals obtaining a key, if you require a replacement at any time, we will only supply the codes to an authorised Fiat dealer, in accordance with very strict security protocols.

What happens if a windscreen or window is damaged and needs to be replaced?

Call the ISR on 01233 333000 to order a pack to mark the replacement glass.

Is it possible for anyone else to obtain my name or any other details through the Register?

No. If asked questions about your vehicle ISR operators will only confirm whether the information quoted to them corresponds to the details held on the Register. If there is any doubt about an enquiry operators may recommend that an enquirer verifies information with the person selling a protected vehicle.
