What NAICS 492110 covers
NAICS 492110 is the classification for Couriers and Express Delivery Services. The federal government uses it to buy time-definite delivery of documents, packages, and small parcels using ground, air, or a combination of both. Think: secure document delivery between agency offices, overnight shipment of medical specimens, priority mail runs between federal buildings, and last-mile delivery for agency procurement orders.
It does not cover freight transportation of bulk goods (that falls under NAICS 484) or local messenger services under a courier's own brand (NAICS 492210). If you operate a route-based delivery business with scheduled pickups and deliveries, 492110 is your code.
Which agencies buy under this code
Department of Defense (DoD) is the largest single buyer. Military installations across the country run continuous intra-base and inter-installation delivery operations. The Defense Logistics Agency (DLA) alone manages billions in supply chain activity, with courier services supporting classified and unclassified document transfer, parts delivery to maintenance depots, and medical supply runs.
U.S. Postal Service contracts out last-mile delivery on specific routes and during peak volume periods. USPS Highway Contract Routes (HCR) and City Carrier Assistant support contracts fall partly under this NAICS when carriers act as agents for package delivery.
General Services Administration (GSA) procures courier services centrally for civilian agencies and manages the contract vehicles most small businesses will use to enter this market.
Veterans Affairs (VA) runs a large medical supply and specimen transport network across 170+ VA Medical Centers. Secure chain-of-custody delivery of lab samples and pharmaceuticals is a consistent procurement need.
Department of Justice and Federal Courts also appear regularly in 492110 awards for secure legal document delivery and evidence transport.
Annual federal spend and trend
Direct federal contract spending under NAICS 492110 runs between $2 billion and $2.5 billion annually based on USASpending.gov award data. The figure has held relatively steady over the past three fiscal years, with modest growth tied to VA medical facility expansion and DoD installation consolidations that create new inter-facility delivery demand.
The larger opportunity is indirect. Prime logistics contractors on large DoD and civilian agency IDIQ vehicles frequently subcontract last-mile and regional delivery work to small businesses. That indirect spend is harder to quantify but is generally estimated at several times the direct contract volume. If your target is a first contract, indirect teaming with a prime is often the fastest path in.
Set-aside contracts in this NAICS have increased as a share of total awards. In FY2023, small-business set-asides accounted for roughly 38% of 492110 awards by dollar value, a number that reflects both the SBA's size standard and the geographic nature of courier work, which lends itself to regional small-business performance.
SBA size standard
The SBA size standard for NAICS 492110 is $47 million in average annual receipts (measured over the prior three fiscal years). This is a revenue-based standard, not an employee count. Most regional courier companies qualify easily. Even mid-size regional carriers with 200 to 400 employees typically fall under this threshold.
Verify your size before certifying. The SBA's Size Standards Tool at sba.gov confirms the current threshold, and the rules for calculating average receipts include affiliated businesses.
Set-asides that apply here
8(a) Business Development Program is the most active set-aside in this NAICS for new entrants. SBA 8(a) sole-source contracts are available up to $4.5 million for goods and services (higher thresholds apply to manufacturing), making them accessible for route-based contracts and single-installation delivery vehicles. If you're 8(a) certified and within driving distance of a military installation or federal campus, this is your most direct entry point.
HUBZone certifications show up frequently in 492110 awards, particularly for DoD contracts on or near installations located in historically underutilized business zones. Check the HUBZone map against your service area before applying.
SDVOSB (Service-Disabled Veteran-Owned Small Business) is heavily used at VA. The VA is required by the Veterans Benefits, Health Care, and Technology Improvement Act to give priority to SDVOSBs and VOSBs before opening competition. If you're a veteran-owned courier, the VA's supply chain and medical center network is a natural first market.
WOSB (Women-Owned Small Business) set-asides apply to this NAICS because courier services fall under a federally designated underrepresented industry for women. Confirm current WOSB-eligible NAICS status at sba.gov; the list is updated periodically.
Key contract vehicles
GSA Multiple Award Schedule (MAS) — Transportation and Logistics Services (SIN 531 series): GSA Schedule SIN 531 covers transportation, delivery, and relocation services. Getting on schedule gives you access to the entire federal civilian market through a single vehicle. Agencies can issue task orders against your schedule contract without a full competition. The schedule is competitive to win but worth pursuing if you plan to sell to multiple civilian agencies.
DoD IDIQ vehicles: The Defense Logistics Agency runs several delivery and logistics IDIQs. DLA Troop Support in Philadelphia and DLA Distribution at New Cumberland are the relevant buying offices. Look for open Requests for Proposals through SAM.gov and their forecast pages.
USPS Highway Contract Routes: USPS posts HCR solicitations separately from SAM.gov at about.usps.com/doing-business. These are structured as competitive fixed-route contracts and run three to five years. Small businesses dominate this vehicle.
Agency-specific BPAs and IDIQ contracts: Many large federal campuses (NIH in Bethesda, the Pentagon, GSA regional offices) maintain internal blanket purchase agreements for on-call courier services. These are often competed locally and award to small businesses by default.
Certifications that improve your competitive position
For federal work, the government certifications above (8(a), HUBZone, SDVOSB, WOSB) are the priority. Get SAM.gov registration current before anything else; no federal award is possible without it.
For state and corporate work — which is where DBE and MBE certifications pay off — the picture shifts. State Departments of Transportation use DBE (Disadvantaged Business Enterprise) certification for contracts that involve federal highway and transit funding. If any of your delivery routes touch transit agencies or state-funded logistics programs, DBE status with your state's Unified Certification Program opens that pipeline.
MBE certification through an NMSDC affiliate is relevant if you're pursuing corporate supplier diversity programs. Large retailers, healthcare systems, and manufacturers with federal supplier diversity goals actively source from NMSDC-certified MBEs for their delivery vendor networks. This is separate from federal government contracting but can run in parallel.
Neither DBE nor MBE substitutes for 8(a) or WOSB in federal competitions. They address different buyers.
Finding active solicitations
Start at beta.SAM.gov. Use NAICS code 492110 as your primary filter. Add a second filter for your state or metropolitan area under place of performance. Check "Active" opportunities and set a keyword alert for "courier," "express delivery," and "document delivery."
Set the "Set-Aside Type" filter to "Small Business," "8(a)," "HUBZone," "SDVOSB," or "WOSB" based on your certifications. This narrows the field to opportunities where your status is a direct advantage.
Agency forecast pages are underused. The DoD, VA, and GSA each publish procurement forecasts for the upcoming fiscal year. The VA's Electronic Contract Management System (eCMS) vendor portal lists upcoming procurement actions. DoD's OSBP (Office of Small Business Programs) at installations post forecasts quarterly. These give you 60 to 90 days of lead time before a solicitation appears on SAM.gov.
PTAC (Procurement Technical Assistance Centers) are free counseling offices funded by DoD to help small businesses enter federal contracting. There are over 300 locations nationally. A PTAC counselor can help you read a solicitation, write a capability statement, and review your past performance documentation before submission.
Realistic first-contract path
The single biggest mistake new entrants make is targeting large, full-and-open competitions before they have past performance. Federal contracting officers can't award to a company with zero federal history on a $10 million delivery contract.
Here is a realistic 12-to-18 month path:
Month 1 to 3: Register on SAM.gov. Get your business certifications in order (8(a) applications take 90 days minimum; start immediately if you're eligible). Write a one-page capability statement focused on your service area, fleet size, and any specialized capability (secure chain-of-custody, HIPAA compliance for medical delivery, hazmat endorsement).
Month 3 to 6: Contact your nearest PTAC and schedule a matchmaking session. Attend a local DoD or VA small business outreach event. Most installations hold these two to four times per year. Show up with your capability statement and ask about upcoming needs.
Month 6 to 12: Target a small task order or BPA. A single-installation delivery contract at a federal campus is often under $150,000 and within reach of a small business. Win it, perform, and document it. That past performance reference is what unlocks larger opportunities.
Month 12 to 18: Apply for a GSA Schedule SIN or pursue a subcontracting relationship with a prime logistics contractor. Primes like CEVA, Crowley, or XPO Logistics regularly subcontract regional delivery to certified small businesses. A teaming agreement where you provide last-mile capability while the prime handles the prime contract vehicle is a legitimate path to volume.
The federal courier market rewards reliability and certification status. Agencies want to hit their small-business utilization goals; they need you to make it easy by showing up with clean registration, current certifications, and documented past performance. Start small, perform well, and scale from there.
