It may help to write the numbers down first in case you forget them.
If you say the numbers, make sure your voice is loud and clear. Only you can tell us what the numbers are. If you ask someone to help you, make sure only your face is in the video. To do this you can say the 4 numbers, sign the numbers using British Sign Language, or write the numbers down and show them instead. You will be asked to tell us what the 4 numbers are.
