Company ID in Company Object
I understand that each Person's Company Object has a Company ID value.
What standard is this company ID? Is it a Company Name or is it have a unique number?
I wonder if there is a way to check the Company ID value by Person or to modify it myself.
(This is the case if CRM or API is not linked.)
And if there are People from the same Company(Company Name field value), I wonder if their company ID is the same.
Thank you in advance!
