Great question! These two documents serve different purposes:
Certificate of Incumbency

Lists the current officers, directors, and key executives of the company.

Confirms
who has authority to act on behalf of the business (sign contracts, open bank accounts, etc.).

Issued by the company itself (often signed by the secretary and sometimes notarized).
Certificate of Good Standing

Confirms that your business is
legally registered and up-to-date with required filings (taxes, annual reports, fees).

Issued by the
state or country where your business is incorporated.

Often required when applying for loans, contracts, or foreign business operations.
TL;DR
- COI = Who’s in charge?

- CGS = Is your company legit & compliant?

If you’re setting up bank accounts or dealing with contracts, you’ll likely need
both at some point.
