Your order ID number can be found in the email confirmation you received when you ordered your testing kit. It’s also on the front of the box your test arrived in.
It typically consists of two letters (usually your initials) followed by some numbers (eg: AB12345).
Your Kit ID can be found on the outside of the box the test is delivered in, or on a label stuck on the plastic bag that has the test inside. This number is unique to each test and is 4 numbers followed by 4 digits.
For any PCR test (Fit to Fly PCR, Day 2, Day 5 or Day 8 test) your barcode can be found on the testing tube and should begin NH0 or with a 5.
For any Rapid Antigen test (lateral flow) including fit to fly antigens, your barcode can be found on the testing cassette where you see your result. This should begin with CHR0 or BHA.
