Where can I find the asset / serial number for a Charge post that I want to report as faulty?

There are different types of Charge posts in operation; all should have an easily found sticker with our phone number (0203 056 8989) and an ID number (what we call the serial number) on them. The ID number usually starts by 986 followed by 000 and a further 4 digits, eg 9860001234
