1. Why brokers really reject new MC authorities
A broker who books a load with your truck is trusting you with a customer's freight, often worth far more than the load pays. When they check your MC number, they are not judging your driving. They are looking for evidence that your company is real, insured, and likely to still exist when a claim lands. A brand new authority provides almost none of that evidence, and the broker's system treats missing evidence as risk.
Three reasons drive most rejections. First, no history: a new MC has no inspection record, no safety data, no delivered loads, and no payment track record for a broker to lean on. Second, fraud: freight fraud has made brokers wary of new authorities in particular, because stolen identities and double-brokered loads frequently hide behind recently created carrier accounts with new phone numbers and email addresses. A broker who has been burned once writes a rule that keeps every new carrier out, honest ones included. Third, internal age policies: many brokerages simply set a minimum authority age in their carrier setup system, commonly somewhere between 90 days and 6 months. Below that age the system will not onboard you no matter who you talk to, and the person on the phone often cannot override it.
Understanding this changes how you respond. Arguing with a broker whose policy is 6 months wastes your day. The useful questions are: what is your minimum age, and what would you need to see from me when I reach it? Note the answer, move on, and spend your energy on brokers whose policies you already meet.
2. The honest timeline: days 0 to 30, 30 to 90, 90 to 180
Expect the first 180 days to fall into three distinct phases, because planning around the real timeline keeps you from making desperate decisions in week two.
Days 0–30. Your authority may still be inside its initial activation window, and many brokers will not consider you at all. This month is for setup done properly: equipment ready, insurance certificates in order, your carrier packet assembled (section 4), load board accounts active, factoring arranged if you plan to use it, and a list of brokers and small brokerages that accept new authorities. The loads available now are mostly short, local, and less popular freight. Take them anyway. Every on-time delivery is a reference you did not have in week one.
Days 30–90. More mid-size brokers will talk to you, especially if you can show a clean packet and a few completed loads. Consistency matters more than rate in this phase: brokers remember the new carrier who communicated well and delivered without drama. Keep records of every load and every broker who said yes, because that list is your working book of business.
Days 90–180. A large share of the 90-day policies fall away, and brokers who rejected you in month one will onboard you without discussion. Rates and lane choice improve because you are choosing loads instead of accepting whatever is left. By 180 days most age gates are behind you, including Amazon Relay's activity requirement, covered in section 7. The carriers who struggle at this stage usually spent the first 90 days parked waiting for the wall to drop, instead of building the record that makes brokers want them once it does.
3. Brokers and boards that will onboard a new carrier, and how to approach them
How to get loads with a new MC authority comes down to working the channels that are actually open to you. Start with smaller and mid-size brokerages. They set their own risk rules rather than a corporate age minimum, and many will onboard a new carrier who presents a complete packet and sounds professional on the phone. Regional brokers who move freight in your area are a particularly good fit, because a short first load lets both sides test the relationship cheaply.
Load boards remain the daily hunting ground. Post your truck with your real availability and equipment, dry van, reefer, flatbed and step deck, box truck, or hotshot, and respond fast when a broker calls. Speed matters with new authorities: a broker working down a list will book the carrier who answers and sends documents immediately. Direct shippers are worth approaching locally too, especially smaller warehouses and manufacturers whose freight is too small or too regular for large carriers. A weekly short run with a direct shipper is stable revenue while your authority ages.
Approach matters as much as the channel. Call rather than only emailing, introduce your company in one sentence, state your equipment and where the truck sits, and ask directly whether they work with new authorities. If no, ask for the minimum age and note it. If yes, send the packet while you are still on the call if you can. Brokers judge new carriers on responsiveness, because a carrier who is hard to reach at booking is usually hard to reach at a problem.
4. Your carrier packet: make approval a 60-second yes
Broker setup is a scanning job. The person approving you looks at dozens of packets and approves the ones where every answer is present, consistent, and signed. A complete packet cannot override an age policy, but wherever you are eligible, it decides whether setup takes ten minutes or three days of follow-up emails. Our guide to the truck dispatch documents checklist covers the full set of paperwork; the packet itself should contain your MC authority letter, your W-9 with the company name matching your authority exactly, your certificate of insurance with the broker named as certificate holder when they ask for it, your signed carrier-broker agreement, a voided check or bank letter for payment setup, and your Notice of Assignment if you factor, so the broker pays the right party the first time.
Three details cause most avoidable delays. The company name must be spelled identically on every document; a W-9 that shortens the name on your authority letter restarts the review. Insurance must show current dates and the coverage the broker requires, and an expired certificate ends the conversation. Contact details must be consistent: the phone and email on your packet should match the ones on your FMCSA registration, because mismatched contact details are one of the fraud signals brokers are trained to catch.
Keep the packet as one clean PDF, named with your company and MC number, ready to send from your phone. When the full packet lands in a broker's inbox a minute after they ask, you have answered the question every broker is really asking about a new carrier: is this company organised?
5. Loads to take, and loads to avoid, while your authority ages
In the first 90 days, choose loads for the record they build, not only for the rate on the screen. Short to medium hauls with straightforward loading and delivery suit a new authority: they turn over quickly, pay sooner, and give you more completed loads per month to point to. Loads from brokers you want a long-term relationship with are worth priority even at an average rate, because a broker who has run five clean loads with you stops checking your authority age entirely.
Freight that fits your equipment and your hours is the other filter. A load you cannot legally deliver on time helps nobody; a late first load with a new broker does more damage than declining it. Be honest about your position and your hours of service, and take loads you can cover without cutting corners.
There are loads to avoid. Anything with unclear details, a rate confirmation that does not match what was agreed on the phone, or a broker who pressures you to skip the written confirmation is a risk you do not need while your record is thin. Avoid freight far outside your equipment's proper use, very long deadhead for a marginal rate, and any arrangement where you are asked to haul under another carrier's authority. That last one can end your authority rather than build it. Walking away costs a day; a claim or a fraud flag in your first months costs far more.
6. Factoring in the first 90 days
Cash flow is the quiet problem of a new authority. Brokers commonly pay in 30 days or more, while fuel, insurance, and repairs are due now. Factoring, selling your invoices to a factoring company for an advance at a small percentage fee, exists to close exactly that gap, and many new carriers factor their first invoices whether they intend to factor long term or not.
If you factor, set it up before your first load, not after your first invoice. The factoring company's Notice of Assignment has to be in your carrier packet so brokers pay the factor directly, and retrofitting that after setup confuses payment and delays it. Check three things in the contract: whether it is recourse or non-recourse, because that decides who carries the loss if a broker never pays; what the fee actually is per invoice and whether it rises with how long the broker takes to pay; and whether the contract locks in a minimum volume or a long term you cannot leave. A dispatcher or a fellow carrier who has used the company is a better reference than the sales pitch.
Factoring is a tool, not a business model. As your broker list grows and direct relationships improve your cash cycle, many carriers factor less. What matters in the first 90 days is that a slow-paying first broker does not park your truck.
7. When Amazon Relay and the big brokers unlock
Two milestones change the picture. The first is the cluster of broker age policies expiring between 90 days and 6 months: as each one passes, re-contact the brokers who told you their minimum age and ask for setup again. A simple list kept from day one, broker name, minimum age, date you become eligible, turns your early rejections into a scheduled pipeline.
The second milestone is Amazon Relay. As a general market rule, Relay requires a carrier's authority to have been active for about 180 days, alongside insurance and safety requirements, before a carrier can haul Relay loads. For box truck and smaller equipment operators especially, Relay becomes a useful source of posted loads once you qualify, because the work is booked in an app with clear requirements rather than negotiated load by load. Do not plan your first six months around Relay income you cannot access yet; plan to arrive at day 180 with a clean record so approval is straightforward when you get there.
The larger national brokerages follow the same pattern. Once your authority passes 6 months with deliveries behind it and no claims or fraud flags, the conversation changes from whether brokers will work with you to which freight you want. That is the finish line of the new-authority period, and the first 180 days are about reaching it with your record intact.
Common questions
How long before most brokers will work with a new MC authority?
It varies by brokerage. Many set a minimum authority age somewhere between 90 days and 6 months, while smaller brokerages and direct shippers often work with new carriers from the start if the packet is complete. Ask each broker for their minimum and note the date you qualify.
Can I get loads in my first 30 days at all?
Yes, but expect short, local, and less popular freight, mostly through smaller brokers, load boards, and local shippers. Treat those loads as record building: every clean, on-time delivery makes the next broker conversation easier.
Does hiring a dispatcher help a new authority get loads?
A dispatcher who works with many brokers can put your truck in front of brokerages that trust them, keep your packet moving, and negotiate while you drive. It does not waive a broker's age policy, but it removes the hours of calling and paperwork that are hardest to do from the cab. Look for no forced dispatch, meaning you approve every load before it is booked.
Should a new carrier use factoring?
Many do, because broker payment terms of 30 days or more clash with weekly costs. If you factor, set it up before your first load, understand recourse versus non-recourse, the real fee, and any minimums or term, and put the Notice of Assignment in your packet from day one.
When can a new carrier haul for Amazon Relay?
As a general market rule, Relay expects about 180 days of active authority, plus its insurance and safety requirements. Use the first 180 days to build a clean delivery record so that when you reach the threshold, onboarding is a formality rather than another wall.
New authority and tired of hearing no? Let a dispatcher work the phones.
Our truck dispatch service calls brokers, sends your packet, and negotiates loads for dry van, reefer, flatbed and step deck, box truck, and hotshot equipment, at 5–10% of linehaul or $250–$350 per truck per week, with no setup fees and no long-term contract. The first week is free, and there is no forced dispatch: you approve every load before it is booked.
