ACX Courier Tracking: Real-Time Parcel Status Using Your AWB Number
Need to track an ACX shipment right now? Enter your AWB number — also called your ACX bill number, consignment number, or docket number — in the tracking box below. You’ll get a live status update in seconds. No login. No charge. No waiting.
This guide covers everything: how the tracking system works, what every status means, realistic delivery timelines, how to fix tracking problems, and exactly who to call when something goes wrong. Whether you’re tracking a domestic parcel across India or an international shipment from Sri Lanka, every answer is here.
How ACX Courier Tracking Works
ACX International Courier Services was founded in Sri Lanka in 1989 and has since grown into a logistics network covering 240+ countries. Their tracking system isn’t a basic status page — it’s a live, scan-driven database that logs every physical movement of your parcel from the moment it’s booked to the moment it’s delivered.
Here’s exactly how the system works, step by step:
Step 1 — Booking generates your ACX bill number. The instant a shipment is booked, ACX’s system creates a unique identifier — your AWB number (also called your ACX bill number or consignment number). Every event in your parcel’s journey is logged against this number.
Step 2 — Barcode scanning at every touchpoint. Your parcel gets a barcode label at pickup. Every time it moves through an ACX facility, hub, or delivery vehicle, an operative scans that barcode. Each scan pushes an instant update to ACX’s central database.
Step 3 — Live database sync. ACX uses an integrated ERP (Enterprise Resource Planning) and MIS (Management Information System) to process and sync scan data in real time. When you enter your consignment number into the tracker, you’re pulling from this live system — not cached data.
Step 4 — Silent legs are normal. Air freight, long road routes, and mid-transit stretches between hubs have no scanning infrastructure. This is why tracking occasionally goes quiet for 48 hours on domestic routes, or up to 10 days on international ones. Your parcel is moving — it’s just between scan points.
Step 5 — Delivery triggers proof of delivery (POD). When the delivery executive hands over the parcel, a final scan generates an official POD record — logging the recipient’s name, signature, and the exact time of handover. This is when the “Delivered” status appears in your tracking.
ACX Bill Number — What It Is, Where to Find It, and What It Looks Like
What is an ACX bill number?
Every ACX shipment has one master identifier that follows it from pickup to delivery. Depending on where you see it, it may be called different names — but they all refer to the same number:
- AWB number (Air Waybill number) — the standard tracking term used in the portal
- ACX bill number — printed on physical receipts at ACX branches
- Consignment number — used in booking confirmations and by customer care
- Docket number — used by some ACX branches for domestic bookings
- Tracking number / reference number — used by e-commerce platforms and third-party sellers
All of these work in the same tracking field. If you have any one of them, you can track your shipment.
Where to find your ACX bill number
- On the physical booking receipt handed to you at pickup or at the branch
- In the SMS sent to the registered mobile number at time of dispatch
- In the email confirmation from ACX or the sender
- In your e-commerce order history under “Shipping Details” (Meesho, Flipkart, D2C brands)
- Printed on the barcode label attached to your parcel
Example ACX Bill Number Format
ACX bill numbers are alphanumeric codes, typically 10–14 characters long. Here are the common formats so you know exactly what you’re looking for:
| Format Type | Example | Length | When You’ll See It |
|---|---|---|---|
| Standard domestic AWB | ACX1234567890 | 13 chars | Most ACX branch bookings |
| Alphanumeric with country code | AC123456789IN | 13 chars | Domestic e-commerce shipments |
| Numeric docket | 1234567890 | 10 digits | Some branch-issued receipts |
| International AWB | ACXI12345678 | 12 chars | Cross-border shipments |
Watch for these common errors: The letter “O” and the number “0” (zero) look identical in many fonts. So do capital “I” and lowercase “l”. A single wrong character produces an “invalid tracking number” error. Always copy your ACX bill number from the original receipt or SMS — not from a screenshot or forwarded message where characters may have changed.
How to Track Your ACX Shipment Step-by-Step
Step 1 — Find your ACX bill number or AWB number
Check your booking receipt, dispatch SMS, order confirmation email, or e-commerce order page. It will be 10–14 characters, a mix of letters and numbers.
Step 2 — Enter it in the tracking field above
Type or paste it carefully. If you see an “invalid tracking number” error, re-check for character confusion and make sure at least 4–6 hours have passed since booking — new ACX bill numbers take time to activate in the system.
Step 3 — Click Track
The system returns live results within seconds — a full chronological history of every scan, the current location, and an estimated delivery date.
Step 4 — Can’t find your number? Try tracking by reference
If you don’t have the AWB, check the tracking portal for a “Track by Reference” option. ACX sometimes allows lookup using a seller’s order reference number. If that doesn’t work, contact ACX customer care with your name, the sender’s details, and the approximate dispatch date — they can locate the shipment manually.
Important for Indian shoppers: Always use the AWB or ACX bill number from your order’s Shipping Details page — never the seller’s internal order ID. They are different numbers and only the ACX bill number works here.
Understanding ACX Shipment Status Updates
Every status in the ACX tracking system has a precise meaning. Here is a complete breakdown — what each status means, the normal timeframe, and exactly when you need to take action.
Complete ACX tracking status reference
| Status | What It Means | Normal Duration | Do You Need to Act? |
|---|---|---|---|
| Shipment Booked / Information Received | Label created; parcel not yet physically with ACX | Up to 12 hours | No — wait for “Picked Up” |
| Picked Up / Dispatched | ACX has collected the parcel; journey begins | — | No action needed |
| In Transit | Parcel moving between hubs via road or air | 1–3 days domestic; 3–7 days international | No — wait 72 hours before contacting |
| Arrived at Sort Facility | Reached a major ACX sorting hub | Hours to 1 day | No action needed |
| Customs Clearance in Progress | International shipment under review at Indian customs | 3–5 business days | Prepare commercial invoice and import docs |
| Held at Facility | Parcel physically stopped — address issue, COD pending, or security check | Should resolve in 24 hours | Yes — contact ACX customer care immediately |
| Out for Delivery | Loaded onto local delivery vehicle for today | Same day | Be present at the delivery address |
| Delivery Attempted / Failed | Courier showed up but couldn’t complete delivery | — | Call your local ACX branch within 2 hours |
| Delivered | Parcel handed over; POD generated | — | If not received, email ACX within 24 hours |
| Returned to Sender | Multiple failed deliveries; parcel heading back to origin | — | Contact the sender immediately |
What “In Transit” actually means
“In Transit” is the most misunderstood status — and the source of most unnecessary support calls. It does not mean your parcel is stuck. It means the parcel is physically moving between scan points, on a truck or aircraft, where barcode reading is impossible.
For domestic Indian shipments, a 48-hour gap in updates is completely standard — especially on long-haul routes like Chennai to Delhi, Mumbai to Northeast India, or metro to Tier-3 locations.
For international shipments, a silence of 5–7 days is expected during the air freight leg. There will be no updates between the origin country’s departure scan and the first Indian customs scan. This is not a failure — it is how cross-border logistics physically works.
The right time to raise a concern: 72 hours with no update for domestic shipments. 10 business days with no update for international. Not before these thresholds.
What “Held at Facility” means — and why it needs immediate action
Unlike “In Transit,” this status requires you to act. “Held at Facility” means the parcel has physically stopped and will not move until a person resolves it. Common causes:
- Delivery address is incomplete or incorrect
- A COD payment verification is pending
- A documentation issue during a security or customs check
- The recipient needs to confirm identity before handover
Contact ACX customer care immediately with your consignment number. Every hour of delay increases the risk of the parcel being returned to sender.
Service Timelines: When Will Your Courier Arrive?
Domestic India delivery timelines
| Service | Metro to Metro | Metro to Tier-2 City | Metro to Tier-3 / Remote | Tier-2 to Tier-2 |
|---|---|---|---|---|
| ACX Express | 1–2 business days | 2–3 business days | 3–5 business days | 2–4 business days |
| ACX Standard | 3–4 business days | 4–5 business days | 5–7 business days | 4–6 business days |
| Acx international Courier mumbai | 1–2 business days | 2–4 business days | 3–6 business days | 2–4 business days |
| ACX Courier chennai | 1–3 business days | 4–5 business days | 5–8 business days | 4–7 business days |
| ACX Courier Ahmedabad | 1–2 business days | 2–3 business days | 3–5 business days | 2–4 business days |
International shipments into India — delivery timelines
| Origin | Air Transit | Customs Clearance | Total Estimated Time |
|---|---|---|---|
| Sri Lanka | 2–4 days | 2–5 business days | 4–9 business days |
| Southeast Asia | 3–6 days | 2–5 business days | 5–11 business days |
| Middle East | 3–5 days | 2–5 business days | 5–10 business days |
| Europe / UK | 5–8 days | 3–7 business days | 8–15 business days |
| USA / Canada | 6–10 days | 3–7 business days | 9–17 business days |
Note: All timelines are estimates for standard conditions. Public holidays, peak seasons (Diwali, Eid, year-end), and incomplete documentation can add 1–5 extra days to any timeline. Remote Tier-3 pin codes and Northeast India add 1–3 additional days beyond the estimates above.
What affects your delivery timeline the most
Peak seasons slow everything down. During Diwali, Republic Day, Eid, and year-end periods, ACX — like every courier — handles significantly higher volume on the same infrastructure. Add 1–3 days across all service tiers during these windows.
An incomplete address is the biggest single cause of delay. A missing flat number, wrong PIN code, or no landmark reference can produce a “Held at Facility” or “Delivery Attempted” status that consumes multiple days. Verify the address at the time of booking, not after.
COD verification adds processing time. COD shipments go through an additional verification step before dispatch and at delivery. If anything flags, the parcel stops until manually cleared.
International customs is outside ACX’s control. Indian customs authorities set their own clearance timelines — ACX cannot speed this up. What ACX can do is help you prepare the right documentation. The sooner you submit the correct paperwork, the sooner your parcel clears.
Solving Common ACX Tracking Issues
Problem: “Invalid tracking number” error
Work through these checks in order:
- Has it been at least 4–6 hours since booking? New consignment numbers take time to activate.
- Re-enter the number manually rather than pasting — check for O/0 and I/l confusion.
- Get the number directly from the sender’s original booking receipt, not a forwarded message.
- Use the tracker on this page — third-party aggregator sites sometimes display stale ACX data.
Problem: No tracking update for 2–3 days
Before contacting support, run through this checklist:
- Is today a public holiday or Sunday? ACX runs reduced operations; updates resume the next working day.
- Is it a long domestic route? A 48-hour scan gap on routes like Mumbai–Northeast or Chennai–Delhi is normal.
- Is it an international shipment in air transit? Up to 10 days of silence between origin and Indian customs is standard.
- Is the parcel in Indian customs? Customs can hold a shipment for 3–5 business days with no update. This is a government process — not an ACX delay.
If the estimated delivery date has passed by more than 72 hours and none of the above applies, move to the next step.
Problem: Parcel overdue — how to raise a tracer request
If your shipment is 72+ hours past its estimated delivery date (domestic) or 10+ business days late (international), contact ACX customer care and explicitly ask them to raise a tracer request. This is ACX’s formal internal search process — it triggers a physical search across the hub network, not just a system check.
When raising a tracer, have ready:
- Your AWB number or ACX bill number
- Origin and destination city
- Date of dispatch
- The last recorded status and its timestamp
A tracer request resolves most delayed-parcel cases significantly faster than a general enquiry. Be specific when you call or email.
Problem: Tracking shows “Delivered” but nothing arrived
- Check with neighbours, building security, and management — ACX may have handed the parcel to an authorised person at your address.
- Look for a delivery slip under your door or in your letterbox.
- Ask household members or office colleagues if they accepted it.
- Email cs@acxcouriers.in within 24 hours with your consignment number, full delivery address, and a written statement that you did not receive the parcel.
- Request the proof of delivery (POD) document — it shows exactly who signed for the parcel and when. If the name doesn’t match anyone at your address, this becomes a formal delivery dispute.
Problem: “Delivery Attempted” but you were not home
Call your local ACX branch — not the national helpline — within 2 hours of the notification. Local branches have direct contact with the delivery executive assigned to your route. They can arrange a same-day reattempt in many cases. The national helpline can only schedule a reattempt for the next available slot.
Problem: COD parcel not moving or held
If your COD shipment shows “Held at Facility,” contact ACX customer care immediately with your consignment number and confirm the COD amount. Once payment details are verified, the hold is usually cleared within a few hours.
Problem: Return pickup not updating
Return pickups use a separate AWB number issued specifically for the return — it is different from your original delivery AWB. Get this return consignment number from the seller or the platform you bought from. Once you have it, track it the same way using the portal above.
International Tracking: Sri Lanka to India and Beyond
ACX has operated the Sri Lanka–India corridor since its founding and it remains one of their highest-volume routes. The same ACX bill number issued at origin tracks your shipment end-to-end into India — you do not need a separate tracking number.
The standard journey for an international shipment into India:
Booked at Origin → Picked Up → Departed Origin Country → [air transit — no updates for 5–10 days] → Arrived at Indian Customs → Customs Clearance in Progress → Cleared Customs → In Transit to Destination City → Out for Delivery → Delivered
If your parcel is stuck at “Arrived at Indian Customs”
If this status hasn’t moved in more than 5 business days, Indian customs likely needs additional documentation. Contact ACX customer care with:
- Your AWB or consignment number
- The commercial invoice for the shipment
- Any import permits or NOCs relevant to the goods
- Your IEC (Import Export Code) if this is a commercial shipment
Customs delays are almost always documentation issues, not parcel issues. Getting the right paperwork in promptly resolves most cases within 1–2 business days after submission.
ACX Courier Tracking for E-Commerce Businesses
If you’re dispatching 30–50+ parcels per month through ACX, checking consignment numbers individually is unsustainable. Here’s how serious sellers handle it.
API integration — ACX provides a tracking API that connects to Shopify, WooCommerce, Magento, or any custom OMS. It pushes live status updates directly to your customers with no manual intervention.
Bulk tracking dashboards — Multi-courier aggregator tools let you enter all your ACX AWBs at once for a complete status overview across every active shipment on a single screen. Standard practice for sellers processing 100+ daily orders.
Automated customer notifications — Configure your OMS to send customers their ACX consignment number and a tracking link the moment their order is dispatched. This one automation consistently reduces “Where is my order?” queries by 35–40%.
Proof of delivery for compliance — If you operate in legal services, finance, healthcare, or any regulated sector where delivery confirmation has legal weight, ACX’s computerised POD serves as an official delivery record. Request POD copies from ACX customer care for any delivered shipment — valuable for disputes, audits, insurance claims, and client billing.
COD remittance and returns management — ACX supports COD collection and reverse logistics for business accounts. If you run high COD volumes or manage product returns at scale, ask ACX about a dedicated business account for consolidated billing and priority support.

How to contact ACX customer care effectively
Always have your ACX bill number or consignment number ready before you call or email. Without it, support agents can’t locate your shipment and the call becomes a callback request.
- For delayed or missing parcels, don’t just ask “where is my parcel?” — specifically say you want to raise a tracer request. This triggers an operational search, not just a system lookup.
- For international shipments in customs, email cs@acxcouriers.in with your consignment number and commercial invoice attached. Email is faster for customs cases because the team works from documentation — not verbal descriptions.
- For proof of delivery requests, include your AWB number and delivery address in the email subject line — it speeds up retrieval.

Frequently Asked Questions About ACX Courier Tracking
What is an ACX bill number?
It is the unique identifier assigned to your shipment at the time of booking. Also called an AWB number, consignment number, or docket number — all refer to the same code. It’s 10–14 alphanumeric characters and is your key to tracking the parcel at every stage.
What does an ACX bill number look like?
Common formats include “ACX” followed by 10 digits (e.g. ACX1234567890), a two-letter prefix with digits and a country code suffix (e.g. AC123456789IN), or a 10-digit numeric docket for branch bookings. Always verify from your original receipt.
How do I track my ACX courier shipment?
Enter your AWB number, ACX bill number, or consignment number in the tracking field at the top of this page. Results appear within seconds — no login required.
Can I track without a tracking number?
It is difficult. Try the “Track by Reference” option in the portal using the seller’s order number. If that doesn’t work, contact ACX customer care with your name, the sender’s details, and dispatch date for a manual lookup.
Why is my ACX tracking not updating?
Most likely: the parcel is in transit between hubs (no scanning possible), it’s a weekend or holiday, or it’s clearing Indian customs. Wait 48 hours for domestic and 7–10 days for international before raising a query. If the EDD has passed by more than 72 hours, request a tracer.
What does “In Transit” mean on ACX tracking?
It means your parcel is physically moving between ACX hubs — by road or air — where barcode scanning isn’t possible. It is not stuck. A 48-hour domestic silence and a 5–7 day international silence are both completely normal.
What is proof of delivery (POD) and how do I get it?
POD is ACX’s official delivery record showing who accepted the parcel, when, and where — typically including the recipient’s name or signature. Email cs@acxcouriers.in with your consignment number to request a copy. Available within 24 hours of the “Delivered” status for most shipments.
Can I track an ACX shipment from Sri Lanka to India?
Yes. The same AWB or ACX bill number issued in Sri Lanka tracks the shipment end-to-end into India. Expect a 5–10 day silent period during air transit with no scan updates — this is normal.
How long does ACX Express take to deliver in India?
1–2 business days metro to metro; 2–3 days metro to Tier-2 cities; 3–5 days for remote or Tier-3 locations. These are working-day estimates and exclude public holidays.
What does “Held at Facility” mean?
Your parcel has physically stopped and needs manual intervention to move again. Common causes: incomplete address, pending COD payment verification, documentation issue, or a security check. Contact ACX customer care immediately with your consignment number.
Is ACX courier tracking free?
Yes — completely free. You only need your AWB number, ACX courier tracking number, or consignment number. No registration required.
What should I do if my parcel is lost?
Contact ACX customer care immediately and ask them to raise a formal tracer request. Provide your consignment number, dispatch date, origin city, destination city, and last recorded scan. The tracer process is ACX’s official mechanism for locating missing or misrouted shipments.
Conclusion
ACX Courier’s tracking system gives you real, checkpoint-by-checkpoint visibility across your entire shipment journey — from the first pickup scan to final POD confirmation.
