The UDISE PEN number (Permanent Enrolment Number) is an 11-digit ID assigned to every student in a UDISE+ registered school. Schools generate it once, during student data entry, and it stays with the student across schools, classes, and transfers — unlike a roll number that resets every year.
Key Takeaways
| Point | Detail |
|---|---|
| What PEN stands for | Permanent Enrolment Number — sometimes written Permanent Education Number |
| Format | 11-digit unique identifier, generated once per student |
| Who generates it | The school, through the SDMS Student Module during data entry |
| Does it change? | No — it stays with the student for their entire schooling, including school transfers |
| Related to APAAR ID? | Related but not identical — PEN identifies the student in UDISE+; APAAR ID is the newer NEP 2020 academic credit ID |
What Is a UDISE PEN Number?
PEN stands for Permanent Enrolment Number, sometimes referred to as Permanent Education Number. It’s an 11-digit code the UDISE+ system assigns to a student the first time a school enters their enrollment record. Once generated, the number doesn’t change — even if the student transfers to a different school, state, or board.
This permanence is the entire point. Before PEN existed, tracking a student’s academic history across school transfers relied on paper records and manual verification. Now, a student’s enrollment, attendance, and progression history can follow them through a single ID.
Why Schools and Parents Need It
Schools use the PEN number to track student progression year over year inside UDISE+ — promotions, transfers, and dropout status all reference this ID rather than a name, which can be spelled inconsistently across records. Parents increasingly need it too, since several state scholarship schemes and transfer certificate processes now ask for the PEN alongside or instead of a roll number.
How to Find Your Child’s UDISE PEN Number
1. Ask the School Office First
The fastest route is also the most reliable. Every school that has completed student data entry in SDMS has the PEN on file for each enrolled student. Ask the class teacher or school office directly.
2. Check the Student’s Report Card or Transfer Certificate
Many schools now print the PEN number on report cards and transfer certificates issued after 2022, since it has become a standard identifier alongside the admission number.
3. Check DigiLocker
If the school has linked the student’s records to DigiLocker, the PEN and related academic documents may be accessible there directly, without going through the school.
4. Verify Through the School’s UDISE Code
If you know the school but not the exact PEN, confirming the school’s own UDISE code first can help the school office locate the student record faster in their own system.
Common PEN Number Problems and Fixes
| Problem | Likely Cause | Fix |
|---|---|---|
| PEN not generated for a student | School hasn’t completed student data entry for that academic year | Ask the school to complete entry in the SDMS Student Module |
| Duplicate PEN for one student | Student was entered twice, often after an incomplete transfer | School must raise a correction request with the Block Education Officer |
| PEN doesn’t match across two schools | Old school didn’t mark the student as “Left with TC” before the new school made a fresh entry | Previous school needs to update transfer status so records merge correctly |
| PEN missing after school transfer | New school entered the student as a fresh admission instead of a transfer | New school should search the student’s previous PEN before creating a new record |
PEN Number vs UDISE Code vs APAAR ID
These three IDs get confused constantly, but they identify different things entirely. The UDISE code identifies the school. The PEN number identifies the student within UDISE+. The APAAR ID is the newer, NEP 2020-driven academic credit identifier that links a student’s records across the Academic Bank of Credits system, and it’s generated using data already tied to the student’s PEN.
In practice: a school has one UDISE code, and every student in that school has their own PEN, and increasingly, their own APAAR ID as well.
Expert Insight
Block Resource Coordinators report that most PEN-related complaints trace back to the same root cause: schools treating a transferring student as a brand-new admission instead of searching for their existing PEN first. Training data entry operators to search before they add a new student record eliminates the majority of duplicate PEN cases at the source.
Frequently Asked Questions
What does PEN stand for in UDISE+?
PEN stands for Permanent Enrolment Number, an 11-digit ID assigned to each student when a school first enters their record in UDISE+.
Does the PEN number change if a student switches schools?
No. The PEN number is designed to stay with the student permanently, including across school transfers, as long as the transfer is recorded correctly.
Who generates a student’s PEN number?
The school generates it through the SDMS Student Module during enrollment or new admission data entry.
Is PEN the same as APAAR ID?
No, they’re related but different. PEN identifies the student within UDISE+; APAAR ID is the newer academic credit identifier used for NEP 2020’s Academic Bank of Credits system.
What should I do if my child has two different PEN numbers?
Report it to the current school, who can raise a correction request with the Block Education Officer to merge the duplicate records.
Can parents look up a PEN number without contacting the school?
In most cases, no — PEN lookups aren’t publicly searchable. The school office or the student’s DigiLocker account (if linked) are the reliable sources.
Conclusion
The PEN number exists to solve a real problem: keeping a student’s academic record intact as they move between classes, schools, and states. For parents, the school office remains the most direct way to retrieve it. For schools, the most common issues — duplicates and mismatched transfers — come down to searching existing records before creating new ones during DCF data entry.
