BC Object Registry tracks the object ID ranges your Business Central apps use, and issues new collision-free ranges, from the portal, from Business Central, from VS Code or CI, or from a Copilot Studio agent.

Get started

Sign in with your work email. People on the same company domain share one workspace.
Identify your Business Central tenant (paste its Tenant ID or a Business Central URL). Partners add one tenant per customer.
Import your existing registry (your GitHub registry.json or ObjectRegistry.md, app.json files, or CSV), or add apps one at a time.
Issue a range when you start a new app: pick the size, choose where it will be deployed, and copy the idRanges into app.json.

Key ideas

Collisions are per tenant. Ranges are checked across every PTE app in a tenant, whichever environments they're in. AppSource ranges are partner-wide.
Overlaps are flagged, never silently fixed.
Export any time, including if a subscription lapses.
