What is my reference number and what is it for? For all Competitions before 2019, entrants received an automated reference number when they uploaded. This is the individual reference number, which you will need to download your participation or award certificate. If you submit your entry by post, your reference number will be your first initial, last initial and date of birth in the following form: 8_DDMMYYYY. For example, if your name is John Smith and you are born on 4 March 2004, your reference number would be 8_JS04032004. You will be asked to write this on your postal entry form, and are requested to keep this safe as you will need it to download your participation or award certificate. If you have any questions, please contact [email protected].
