Carrier Document Storage: Best Practices
CarrierLeads Research Team
We build and operate CarrierLeads, the tool that ingests FMCSA authority records every week, verifies them against live federal sources, and runs cold email sequences for dispatchers, brokers and factors.

Carrier documents contain EINs, bank details, and driver licenses. Where they live matters as much as whether you collected them.
The bar is low and most small operations do not clear it: paperwork sits in an email inbox, a phone's photo roll, and a shared drive nobody has audited.
The four rules
Apply these and you will be ahead of most dispatch services.
- One record per carrier — every document for that MC in one place, not by date received
- Expiration date attached to the document, not kept in someone's head
- Private by default — no public links, no shared folder open to anyone with the URL
- Short-lived view links when you need to show a certificate to a broker or shipper
What not to do
Do not keep the only copy in a text message thread. Do not store W-9s in a shared drive that every contractor can browse. Do not email a carrier's voided check to a broker — send the certificate of insurance alone, and only to the party that needs it.
Retention
Keep executed agreements and load-related paperwork for the life of the relationship plus the statute of limitations on contract claims in your state — commonly four to six years. Superseded certificates of insurance can go once a replacement is on file, but keeping them costs nothing and proves you were covered on a given date.
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
- Where should carrier documents be stored?
- In a single per-carrier record with access limited to people who need it, expiration dates attached, and no publicly shareable links.
- How long should I keep carrier paperwork?
- Executed agreements and load documents for the life of the relationship plus your state's contract limitations period, commonly four to six years.
- Is it safe to store W-9s and voided checks in email?
- No. Email inboxes are the most commonly breached place small businesses keep sensitive documents, and they are not searchable by carrier when you need one fast.
- Can I share a carrier's insurance certificate with a broker?
- Yes, and it is routine. Share the certificate alone, ideally via a link that expires, rather than forwarding the whole packet.
