# Primary record selection

When Kernel identifies duplicate accounts, it selects one as the **primary record**. The primary record is the version that will be kept and enriched, while the others are merged into it.

Selection is determined in the following order:

{% stepper %}
{% step %}

#### Duplicate type priority

The type with the highest priority in the group takes precedence. Where multiple types are present, the hierarchy applied is:

**Exact > Location > Regional > Trading > Website**
{% endstep %}

{% step %}

#### Identity type

For **Regional** and **Trading** groups, the legal entity is preferred over the trading entity.

For **Location** groups, the parent entity is preferred over the establishment.
{% endstep %}

{% step %}

#### CRM field values

CRM fields configured for primary selection are compared across remaining candidates. By default, risk score and last activity date are used. The record with the highest value is preferred.
{% endstep %}
{% endstepper %}
