# dinmo\_id

`dinmo_id` is the resolved profile ID assigned by DinMo during [Profile Resolution](/identity-resolution/profile-resolution.md).

It is the primary key of the resolved profile spine and the main key used to join the [golden record](/identity-resolution/golden-record.md), matched identifiers, audit tables, and downstream profile use cases.

## Where `dinmo_id` appears

`dinmo_id` appears in:

* `identity_golden`
* `identity_match`
* `identity_matched_ids`
* `identity_unresolved_records`, when relevant
* Customer Hub, Segments, Activations, analytics, or downstream models that consume resolved profiles

See [Output tables](/identity-resolution/profile-resolution/output-tables.md) for the full warehouse reference.

[Event Stitching](/identity-resolution/event-stitching.md) produces `dinmo_stitched_profile_id`, not `dinmo_id`.

## How `dinmo_id` is created

DinMo creates `dinmo_id` by applying [matching rules](/identity-resolution/profile-resolution/matching-rules.md) inside an [identity graph](/identity-resolution/identity-graph.md).

Records that match according to the configured rules are grouped into one resolved profile and receive the same `dinmo_id`.

## ID continuity

`dinmo_id` is designed to remain stable across normal runs. In most cases, existing resolved profiles keep the same `dinmo_id` as new source records are added or updated.

A `dinmo_id` may change only when the resolved identity graph itself changes, for example when two previously separate profiles are merged after new matching evidence appears, or when matching rules or source data are materially changed.

Downstream systems should treat `dinmo_id` as the current resolved profile key and use [Review and monitor](/identity-resolution/profile-resolution/review-and-monitor.md) to track identity changes over time.
