Using unique number to filter information

Hello,

Hello,

Can anyone help, setting up childcare voucher scheme and have set up register in excel in sheet 1
a2- voucher no ie. 1 (unique value)
b2 - name
c2 - payroll no
d2 - childcare provider name

in sheet 2 i have made up childcare voucher that gets printed off and given to employee

Ideally in sheet2 if I type in voucher number information the rest of the information would filter into the form.

Would be so greatful for some guidance!
