ACI Logistix is a California-based parcel consolidator and e-commerce fulfillment specialist that injects millions of small parcels into the USPS network every week. Its proprietary tech platform delivers real-time shipment tracking, nationwide two- to eight-day transit times, and an easy web form for customer support.
What Is ACI Logistix and Its Services
ACI Logistix is a U.S. logistics provider that blends five decades of mail-distribution know-how with technology built for modern e-commerce. The company acts as a postal consolidator, collecting small parcels from online merchants, presorting them, and injecting them directly into the USPS last-mile network. By bypassing upstream sort centers, ACI shortens delivery times while driving down costs for retailers of every size.
Its service portfolio spans domestic parcel consolidation, international parcel forwarding, and full third-party fulfillment. Merchants can outsource storage, pick-pack, labeling, and transportation, then surface live tracking events through an API. Flexible service tiers—Express, Standard, and Economy—let shippers control the speed-versus-price trade-off for every order.
Behind the scenes, a proprietary logistics operating system optimizes routing, predicts ETAs, and pushes shipment-tracking alerts by e-mail or SMS. Clients get a branded portal that merges multi-carrier status feeds, while shoppers enjoy a single, mobile-friendly “Track Now” screen. With distribution hubs on both coasts and partnerships that reach 230-plus countries, ACI Logistix supports everything from heavyweight catalog drops to lightweight fashion parcels.
How Shipment Tracking Works
Every parcel is scanned at pickup, hub sort, USPS injection, and final delivery. Those scan events feed ACI’s Track & Trace engine, providing end-to-end visibility for senders and recipients alike.
Tracking Number Format
All ACI Logistix tracking numbers begin with the prefix ACI followed by a series of digits (for example, ACI1234567890). This consistent structure makes automated carrier detection simple on multi-tracker websites.
How to track ACI Logistix shipments?
To track ACI Logistix shipment, enter your tracking number into the designated field and click on the "Carrier" button. Then, select "ACI Logistix" from the list of options. If you're unsure which carrier is handling your shipment, the system can automatically identify it for you. Afterward, click the "Track" button. You will be redirected to a tracking results page, where detailed information about your shipment's status and location will be displayed.

Frequently asked questions about ACI Logistix shipment tracking issues
Why does my tracking number return “No information found”?
Newly created labels may take up to eight hours to appear in the ACI Logistix database. Double-check that your tracking number begins with the “ACI” prefix and contains only digits afterward. If no events appear after one full business day, contact the seller or submit the web form on ACI’s Contact Us page.
My parcel’s status hasn’t updated for 24–48 hours—should I worry?
Short gaps between scans are common while parcels travel between ACI hubs and the USPS processing center. Most domestic shipments receive an update at least once every business day. If nothing changes for more than three business days, open a support ticket with your tracking number and delivery ZIP.
The shipment is stuck on “In Transit.” Does that mean it’s lost?
“In Transit” simply means your package is moving through the network but has not yet reached the next scan point. Continue monitoring the timeline; if there is still no movement after five business days, file a trace request through the Contact Us form.
Why does the USPS page say “Awaiting item” even though ACI shows movement?
ACI injects parcels directly into the destination USPS facility. Until USPS receives the physical hand-off, its system will show “Awaiting item.” You should see a USPS scan within 24 hours of ACI’s “Tendered to USPS” event.
My package shows “Delivered” but I haven’t received it—what now?
First, examine any delivery photo in your tracking portal, then check around porches, garages, and with neighbors or building staff. If it is still missing after those checks, report “Delivered but not received” via ACI’s support form and include your tracking number and full delivery address.
What does “Held in Customs” mean?
For cross-border shipments, this status indicates your package is awaiting clearance. Customs processing can add several days. Provide any requested documentation promptly and keep monitoring your tracking timeline for updates.
Why am I seeing an “Invalid tracking number” error?
Ensure you entered the full code exactly: it must start with ACI followed by numbers only. Common mistakes include extra spaces and swapping the letter “I” with the number “1.” If the code still fails, verify it with the sender.
Can I change my delivery address after the parcel has shipped?
Address changes are possible only before ACI hands the parcel to USPS. Submit a request through the Contact Us form with the correct address and your tracking number; rerouting is not guaranteed and may add one or two days to transit time.
When should I open a lost-package claim?
For domestic U.S. deliveries, wait five business days after the last scan. For international or APO/FPO addresses, allow ten business days. Then use ACI’s Contact Us form to start an investigation and, if applicable, a compensation claim.
