Endorsement
An endorsement is a written amendment to an insurance policy. It can add, remove, or change coverage, insureds, property, or terms, either at issuance or mid-term. Once issued, the endorsement is part of the policy contract and overrides the base form wherever the two conflict.
Everyday examples
Add a vehicle or a driver. Add an additional insured or a waiver of subrogation. Raise a limit, change a mailing address, add a newly acquired location. Some endorsements are premium-bearing, meaning they change what the client pays. Others, like an address correction, do not.
Terminology note: in property and casualty the word is endorsement. In life and health the same idea is usually called a rider.
How the work flows in an agency
A change request arrives by email or phone. The account manager processes it in the carrier portal or sends it to underwriting, updates the agency management system, and confirms the change to the client in writing with the effective date. Skipping the written confirmation is how disputes start.
The requested date and the approved effective date can differ. Follow the policy provisions, delegated authority, and carrier process, and confirm the actual date and time of the change. Do not promise backdating or assume a request has taken effect because it was sent.
Keep three dates distinct
Record when the client requested the change, when it was submitted, and the approved effective date. If they differ, make the difference visible in the account record and client confirmation. That is more useful than a single activity marked done.

Common questions
Is an endorsement the same as a rider?
Same concept, different lines. Property and casualty policies use endorsement. Life and health policies usually say rider.
Does every endorsement change the premium?
No. Premium-bearing endorsements like adding a vehicle or raising a limit change the bill. Administrative changes like a corrected address usually do not.
