What is Alumni Book?
Alumni Book connects people through the schools they shared. Every member adds where — and when — they studied. That single fact, verified by alumni administrators, automatically places you in your real class, so you can find the right people instead of strangers with similar names.
Reunite
Find classmates from every level you attended, even after moving cities or changing numbers.
Network
Discover alumni in your field, your city or your industry — with the trust of a shared school.
Collaborate
Organise reunions, mentoring, scholarships and social projects with your class or school community.

Every school in Indonesia, in one place
Our school directory comes from the official Kemendikdasmen reference data: names, NPSN codes, full addresses and map locations — so classmates find the same school, written the same way.
Sources: Kemendikdasmen reference data; postcodes derived from the open “kodepos” dataset (Apache-2.0).
Your privacy comes first
- You decide who sees your email, phone, photos and location — everyone, your class, your connections or nobody.
- Classes are verified, so “same class” really means same school, level and year.
- No public profiles: member data is visible only to signed-in alumni.
- Encrypted connections, rate limits and audit logs protect every account.
Take your alumni network with you
Alumni Book works in any browser on phone or computer — and as an Android app.
Android 7.0 or newer. Allow installing apps from this source when asked.
Frequently asked questions
Is Alumni Book free?
Yes. Creating an account, finding classmates, joining groups and chatting are free for alumni.
Which schools are included?
All elementary, junior high and senior high schools (including madrasah and SMK) and higher-education institutions in Indonesia's official reference data — more than 290,000 institutions.
How does verification work?
After you add a school and class year, alumni administrators confirm it. Verified records unlock your class network and a trusted badge.
Who can see my information?
Only signed-in alumni, and only the fields you allow. You can hide your email, phone, photos and location, or limit them to your class or connections.
I can't find my school. What now?
Search by name, NPSN or address. If it still isn't listed (for example a school that has closed), you can suggest it and administrators will add it.
Can schools or alumni associations use it?
Yes. Associations can publish announcements, verify members and organise groups for their school.
