ICO Registration Number

All companies that handle data in any form must be registered with the ICO (Information Commisioners Office) It is an offence if you hold or process data and are not registered.

Registration is easy and is done online at https://ico.org.uk/ . For most organisations there is a £40 fee but it can vary.

The ICO Registration number is a requirement of the Toolkit and you cannot complete the Toolkit without it

If you are registered but cannot find your ICO number, you can search for it here https://ico.org.uk/esdwebpages/search
