What is the correct place to find the MOT test centre number on my certificate?

To locate the MOT test centre's VTS site number on your certificate, look for it next to the testing organisation name. If you have a paper certificate, it will typically be there. Alternatively, check the refusal of test certificate document for this information. The VTS site number can appear in various formats, including a 5-digit number or a six-digit ID consisting of four numbers and two letters. Sometimes, it's even a seven-digit ID with a letter followed by six numbers. This unique identifier helps to specify the location where your vehicle was tested, aiding in future inquiries or reporting procedures related to the MOT test.
