Duplicate google keyword id

[Zingler42]

When we upload keywords, sometimes the same id is returned for the same keywords but from different companies and adgroups. For example:

<adGroupId>58665346260</adGroupId> 

<criterion xsi:type="Keyword"> 

<id>393235640101</id> 

<adGroupId>58665347420</adGroupId> 

<criterion xsi:type="Keyword"> 

<id>393235640101</id> 

<adGroupId>58665347940</adGroupId> 

<criterion xsi:type="Keyword"> 

<id>393235640101</id>

Is it legit issue for same keywords? If so, why ids not always the same?

Hi,

Yes, this is an expected behavior. The keyword id alone is not globally unique. But the combination of ad group id + keyword id (criteria id) will be a unique combination. Please check this guide for more clarity.
