What is ULN (Unique Learner Number)?
Also known as: unique learner number
A ULN (unique learner number) is a 10-digit number that identifies a learner, usually from age 14, across education and training in England and Wales. It is issued through the Learning Records Service and links to the learner's personal learning record, which shows their qualifications and achievements throughout their life.
The ULN is used mainly for qualifications. Schools, colleges and training providers register learners with the Learning Records Service, which issues the ULN. Awarding bodies then use it to add qualification results to the learner’s personal learning record (PLR). Most learners aged 14 or over have a ULN, and it stays with them for life, whatever they study and wherever they study it.
Learners can find their ULN on exam certificates or results slips, or ask their school, college or training provider. Once they have a ULN, they can view their own personal learning record online.
England and Wales
ULNs are used in both England and Wales, and there is separate guidance for schools in Wales on using the ULN service. The UPN (unique pupil number) is different: it identifies pupils in state schools, whereas the ULN follows learners into further education, training and beyond.
Why it matters for your setting
- If your pupils take qualifications, their ULN helps make sure results are recorded on the right learning record.
- Colleges and training providers may ask for a ULN when a young person moves on.
- Like any identifier, a ULN is personal data and should be kept securely.
