How Old Is a Carrier's Authority? Why the Date Matters (2026)

Authority age — the number of days since the FMCSA granted operating authority — is the most predictive field in the entire carrier record for anyone selling to carriers.
It also matters on the risk side: many shippers and insurers treat carriers under twelve months old differently.
Why the date predicts everything
A carrier under thirty days old has no dispatcher, no broker relationships, and usually no factoring company. A carrier at eighteen months has all three and no reason to change.
Reply rates on cold outreach fall off a cliff after the first month. That is not a copywriting problem — it is a timing problem.
- 0–30 days: unattached, highest reply rate, decision window open
- 1–6 months: partially attached, still switchable if something is broken
- 6–24 months: attached, but MCS-150 refilings signal renewed activity
- 24+ months: established, needs a displacement pitch not an introduction
Where the date comes from
The authority grant date is published in FMCSA licensing records. The MCS-150 biennial update date is a separate field and a useful second signal — a carrier who just refiled is actively operating rather than dormant.
Reading the record field by field
The authority age check pulls a handful of dates and status fields off the FMCSA record, and each one means something different. Confusing them is the single most common mistake in this kind of prospecting.
- Authority grant date — when the MC number was first activated, the field this whole page is about
- MCS-150 last update — when the carrier last filed its biennial census update, a proxy for how active the operation currently is
- Operating status — active, revoked, or out-of-service; a carrier with an old grant date can still show inactive status
- Insurance filing date — when the current BMC-91/91X or equivalent was filed, which can change independently of the authority date
- Entity type — sole proprietor, LLC, or corporation, useful context when the same person reappears under a new MC number
What goes wrong when people read this data
The most common error is treating MCS-150 date as authority age. A carrier who has run for six years but refiled its census update last week will look brand new if you read the wrong field — it is not, and pitching it as a first-time authority will read as a research failure, not a pitch.
The second common error is trusting a single snapshot. A carrier can look active on Monday and show a lapsed insurance filing on Friday. If you are working a list over more than a few days, re-check status rather than relying on the day you first pulled the record.
The third is ignoring reinstated authority. Some MC numbers were revoked and later reinstated — the grant date on file may reflect the original grant, not the reinstatement, which can make a carrier look older or newer than its actual operating history.
A short worked example
Say a lookup returns an authority grant date of twenty-two days ago, an MCS-150 filed the same week, and active status with a current insurance filing. That combination is the strongest possible new-authority signal: freshly granted, freshly filed, and compliant — the carrier almost certainly has no dispatcher or broker relationship yet.
Compare that to a carrier with a grant date three years back but an MCS-150 filed last month. That is not a new-authority lead at all — it is an established carrier that just completed its routine biennial update. Read together, the two dates tell you which pitch to use.
Using authority age on the risk side
Some shippers require twelve months of authority before a carrier can haul their freight, and insurance premiums are materially higher under that mark. If you are brokering, know your customer's threshold before you tender.
Verifying against live FMCSA records before you act
Any authority age figure is only as good as the moment it was pulled. Before you tender a load or send an outreach message based on it, re-check the live FMCSA record for operating status, insurance filing currency, and any recent out-of-service order — a number that was accurate last week is not a substitute for a same-day check on anything that affects payment or liability.

How we source this
Primary federal sources
Authority, insurance and safety facts come from FMCSA registration data, the Licensing & Insurance system, and the QCMobile API — not resold list files.
Refreshed weekly
Our ingest re-pulls new and re-filed authorities every week, then re-checks status before a record is ever shown or emailed.
Written from operating experience
Sequence structure, timing and copy guidance reflect the outreach we run inside the product from members' own mailboxes, under CAN-SPAM and TCPA constraints.
Verify any single carrier yourself with our free USDOT authority lookup, which queries the federal record live.
Frequently asked questions
- What counts as a 'new' motor carrier?
- Most people in freight sales mean authority granted within the last thirty days. Insurers and shippers usually draw the line at twelve months.
- Where do I find a carrier's authority date?
- FMCSA licensing records publish the grant date. Our free authority age checker returns it from an MC or USDOT number.
- Is the MCS-150 date the same as the authority date?
- No. MCS-150 is the biennial update filing. A recent refiling means the carrier is actively operating, which is a separate and useful signal.
- Why do shippers care about authority age?
- Loss history is thin under twelve months, so insurers price it higher and some shippers exclude those carriers entirely.
- Can a carrier's authority age reset?
- The original grant date usually stays on file even after a revocation and reinstatement, so check operating status separately rather than assuming a clean record means a fresh grant date.
- How often should I re-check authority age on a working list?
- Weekly is reasonable for an active prospecting list, since the newest, most valuable records age out of the window fast and status can change in between checks.
