Answer

Yes — Digambar Jains can also register on a portal if that portal is meant for the wider Jain community. For example, the JISO Sangh Registration portal explicitly includes Shwetambar, Digambar, Sthanakvasi, and Terapanth. ( app.jiso.org.in)

Explanation

So if you are asking about a Jain Shravak ID registration, the key point is this:

• If the site is for all Jain sects, Digambar members can register there. ( app.jiso.org.in)
• If the site is for a specific sect or organization, then registration depends on that portal’s rules. That would need to be checked on the same portal.

I also found another Jain platform that says its service is for all Jain sects, including Digambar. ( jio.net.in)

Spiritual Understanding

In Jain Dharma, the deeper identity is Jain and Shravak/Shravika. Sect differences should not create unnecessary barriers when a service is intended for the whole Jain sangh.

Takeaway

If the registration portal is open to all Jains, then Digambar members can register. If it is sect-specific, then it depends on that platform’s policy.
