A broker of record (BOR) letter, also called an agent of record (AOR) letter, is a signed letter from an employer to an insurance carrier naming the licensed broker who represents the company on its policy. It changes who services the account. It does not change the plan, the rates, the network or anyone’s ID card.

- One letter per carrier. Medical, dental, vision, life and disability each need their own.
- Any time of year. You do not have to wait for renewal to change brokers.
- Employees notice nothing. Coverage, claims and networks carry on exactly as before.

Most employers discover the broker of record letter at an awkward moment: they have decided their benefits advisor is not earning the commission, renewal is six weeks out, and nobody wants to blow up the health plan to fix a service problem.
The good news is that the two things are separate. Changing brokers does not change your insurance. A broker of record letter is the short, unglamorous document that makes that separation possible, and it is worth understanding before you need it.

What the Letter Actually Does
A broker of record letter — BOR letter, or agent of record letter — is a signed notice to your insurance carrier telling them that a new agency now represents you on a specific policy, and that the previous agency no longer does.
That is the whole function. It is one page on your company letterhead. The signature is essentially the entire lift on your side; your new employee benefits broker prepares the document and submits it.
What it is not is a cancellation, a plan change, or a re-enrollment.
What Does Not Change
This is the part employers most often get wrong, and the reason a broker change gets postponed for years longer than it should be.
When a BOR letter takes effect, your carrier stays the same. Your plan design stays the same. Your network, your premiums, your deductible and out-of-pocket accumulators, and your employees’ ID cards all stay exactly as they are. Nobody has to re-enroll. No employee sees a different doctor or restarts a deductible.
The only thing that changes is which agency the carrier pays commission to, and therefore which agency owns the service relationship — the renewal negotiation, the claims escalations, the compliance calendar, the open enrollment meetings.
An employer who is unhappy with their advisor but happy with their plan can act on the first without touching the second.
Agent of Record or Broker of Record?
The two terms are used interchangeably, and carriers are not consistent about which appears on their own paperwork. Both name the party authorized to service the policy and receive its commission, and a letter using either term is generally accepted. Use whichever wording your carrier uses and the intent will be clear.
What Has to Be in a Valid Letter
Carriers reject BOR letters for administrative reasons more often than for substantive ones. A letter that gets processed on the first pass contains:
- Your legal entity name, on company letterhead. Not a DBA, not a trade name — the name on the policy.
- The carrier and the specific policy or group number for each line being moved.
- The new agency’s details — legal name, address, and whatever producer or tax identification that carrier requires.
- Explicit appointment language. The letter must both name the new agency as broker of record and remove the prior one. Naming only the new agency leaves the change ambiguous.
- An effective date. This is the field that determines everything downstream, and the one most worth thinking about.
- A signature and title from someone with authority to bind the company. An HR coordinator’s signature will usually be bounced back; an officer’s or owner’s will not.
A Broker of Record Letter Template
Most carriers accept a letter in roughly this form, on company letterhead, signed by someone authorized to bind the plan. Some carriers have their own form and will ask you to use it instead, which is worth checking first.
[Company letterhead] [Date] [Carrier name] [Carrier address] RE: Appointment of Broker of Record — [Group name], Group/Policy No. [number] To whom it may concern: Effective 2026, [Company name] appoints [Agency name] as Broker of Record for all group insurance coverage currently in force with [Carrier name] under the group or policy numbers listed above. This appointment supersedes any prior broker or agent of record designation and remains in effect until revoked in writing by [Company name]. [Agency name] is authorized to receive all information regarding these policies, including claims experience, renewal and rating information, and to act on our behalf in servicing this coverage. This letter does not authorize any change to plan design, carrier, rates or covered members. Sincerely, _______________________________ [Name], [Title] [Company name] [Phone] | [Email]
You Will Probably Need More than One
A single letter rarely covers a whole benefits program, and this catches employers off guard. Carriers generally require a separate BOR letter for each one. A blanket document naming every carrier at once is typically not accepted.
A Michigan employer with medical at Blue Cross Blue Shield of Michigan or Priority Health, dental at one carrier, vision at another, and group life and disability at a third is looking at four or five separate letters, each with its own policy numbers and its own processing queue. They will not all take effect on the same day.
Ask your prospective broker to inventory every line of coverage before anything gets signed, so nothing gets orphaned. An ancillary line that quietly stays with the old agency is the usual casualty.
Timing: you do not have to wait for renewal
There is a widespread belief that broker changes happen at renewal. They do not have to. A broker change is not a plan change, and it can be made in March as easily as in October.
In practice, mid-year is often the better choice. A broker who arrives eight weeks before renewal inherits a process already in motion: the census is submitted, the carrier has issued its number, and the window for doing anything strategic has closed. A broker who arrives in the spring has time to work the actual cycle — clean the census, look at the claims data, test the funding structure, and go to market properly. That is where benefits strategy work actually happens.
If you are already inside your renewal window and considering a change, the honest question to ask a prospective broker is what they can realistically accomplish in the time remaining. Sometimes the right answer is to move now and let them own the following year.
What Happens After You Sign
Expect two overlapping clocks.
The countermand window. Your incumbent broker is notified and generally has a window — commonly five to ten business days, though it varies by carrier — to contest the change or ask you to rescind it. Many use it to come back with a fee concession or a warning about the transition. This is normal, and it is worth deciding before you sign rather than during the window, when the conversation is emotional and the clock is running.
Carrier processing. Once the window closes, appointment processing typically takes anywhere from a few days to about two weeks depending on the carrier. A complete handoff — files, service history, open claims issues, pending eligibility items — usually runs 30 to 60 days from the signed letter.
Some carriers impose their own waiting periods or blackout rules around renewal. Confirm each carrier’s rules before you fix an effective date rather than after.
The One Risk Actually Worth Checking
Everything above is administrative. There is one substantive risk, and it has nothing to do with your insurance.
Brokers frequently bundle services that are contracted through the agency, not the carrier: a benefits administration platform, COBRA administration, an HR or compliance portal, sometimes an ACA reporting service. Those agreements can end when the broker relationship ends, and unlike your health plan, they will not simply carry over.
Before you sign anything, list every system your HR team touches for benefits and establish, for each one, who holds the contract. Where the incumbent agency holds it, you need either a transition plan or a replacement ready on day one. An employer who loses their benefits administration platform mid-plan-year has a real operational problem, and it is entirely avoidable with one conversation in advance. The same goes for the ERISA compliance calendar — make sure someone owns it on the day the handoff happens.
The Mistakes That Cause Rework
- Backdating the letter. Carriers reject it, and the whole sequence restarts.
- Wrong or missing policy numbers. The single most common cause of a bounced letter.
- Missing signature, or a signature without authority to bind the company.
- Sending it too close to renewal and leaving the new broker no room to remarket.
- Forgetting the ancillary lines, which then sit with an agency that no longer has any reason to service them.
What to Ask Before You Sign
A prospective broker should be able to answer these without hedging:
- Which lines of coverage are you moving, and how many separate letters is that?
- What is each carrier’s processing time and countermand window?
- Which of our current benefits services are contracted through our existing agency rather than a carrier?
- Given today’s date and our renewal date, what will you actually be able to do this cycle?
- How are you compensated on this account, and does that change anything about our current rates?
If the answers are vague, that is information too.

Questions We Get
What is a broker of record letter?
A short signed letter from the employer to its insurance carrier naming a new broker or agency as the broker of record for a policy. It is an instruction to the carrier, not a contract with the new broker, and it transfers servicing rights and commission on the existing policy.
What does AOR mean in insurance?
Agent of record. In practice AOR and BOR are used interchangeably — both name the person or agency authorized to service a policy and receive its commission. Carriers use different wording on their own forms, so use whichever term appears on your carrier’s paperwork.
Does changing your broker of record disrupt employee benefits?
No. A broker of record letter changes who services the policy, not the policy itself. Your carrier, plan design, network, rates, deductibles and member ID cards all stay the same, nobody re-enrolls, and employees generally never notice it happened.
How do I change my broker of record?
Put the request in writing on company letterhead, naming the current carrier, the group or policy number, the new agency and the effective date, signed by someone authorized to bind the plan. Send it to the carrier, usually copying the incoming broker. Most carriers acknowledge it in writing once processed.
How long does a broker of record letter take?
Carriers commonly apply a short waiting period — often around ten days — before the change takes effect, which gives the incumbent broker an opportunity to respond. Timing varies by carrier, so confirm the specific process with yours.
Can a broker of record letter be rescinded?
Yes. An employer can withdraw or replace a broker of record letter by sending the carrier a further signed letter. The most recent valid letter on file governs.
Does changing brokers change my rates?
Not by itself. Your rates are set by your carrier based on your group, not by who services the account. A new broker can affect future renewals by marketing your group or changing plan design, but the act of signing a letter does not alter current pricing.
Do I need a separate letter for each carrier?
Usually yes. A broker of record letter applies to the carrier it is addressed to, so an employer with medical, dental, vision and life coverage with different carriers generally sends a separate letter to each.
When is the best time to change brokers?
A letter can be sent at any point in the year, but the leverage sits before renewal. A broker appointed with enough runway can market your group and influence the renewal; one appointed after rates are set is mostly limited to service until the next cycle.
