ACS Courier is a Greek courier and postal-services company that has operated in Greece since 1981. It runs an extensive service network across Greece, Cyprus, Albania and Bulgaria, with more than 600 service points across these four countries. ACS serves individuals, businesses and e-commerce merchants with domestic and international shipment services.
Within its own network, ACS provides collection, sorting, transportation and delivery of documents and packages, along with options for delivery to an address, collection from service points and ACS Smartpoint Lockers. Customers can also use services such as online pickup requests, shipment redirection, cash on delivery and return shipments, depending on the market and service selected.
For international transportation, ACS Net Express connects Greece with the other countries in its autonomous international network: Cyprus, Albania and Bulgaria. ACS also serves destinations outside its own network through partnerships with international courier companies. Other international options include ACS Europe 5 for less urgent European Union shipments, ACS World Express, import services and economy products for selected routes.
Technology is an important part of ACS operations. Its online tools and mobile application support Tracking, pickup requests, shipment management and delivery changes, while ACS Smartpoint Lockers provide another way to send or collect eligible packages. For shipment visibility, every standard ACS shipment receives a unique shipping number that can be used for package tracking throughout its journey.
How ACS Courier shipment tracking works
To Track an ACS Courier package with 4Tracking, enter the shipment tracking number in the tracking field. Select ACS Courier if a carrier button is available, or allow 4Tracking's automatic carrier detection to identify the courier. Press the Track button, and you will be redirected to the results page where available shipment events, locations and delivery-status updates are displayed.
ACS also provides Track and Trace on its own website. The official system allows customers to search using a shipping number or the number from an absent-delivery notice. Multiple shipments can be searched at once on the ACS website by entering their numbers separated by spaces. ACS also provides Tracking through its mobile application and digital-assistant services.
A tracking event appears when ACS records a new operational step for the shipment. Therefore, there may be periods without a new scan while a package is traveling between facilities, awaiting local processing or moving toward its delivery area. For the clearest result, enter the complete ACS shipment number exactly as it was supplied by the sender or ACS.
ACS Courier tracking number formats
ACS officially identifies its normal shipment number as a 10-digit number. The company uses this 10-digit shipment code for services including ACS Smartpoint Locker shipments and its shipment-return service, where a new return shipment receives its own unique 10-digit code.
The tracking number should therefore normally appear as 10 numerical digits. Because ACS does not publish a broader public specification listing every possible identifier used by every international partner or specialized service, do not change a number supplied with your shipment simply to make it fit a pattern. The ACS Track and Trace system can also accept an absent-delivery note number, which is a different identifier used when a delivery attempt has been recorded.
If you receive an international package that was initially handled by another courier, you may receive a separate ACS tracking number after the shipment enters ACS handling. For example, ACS Cyprus specifically states that certain DPD or SPEEDY shipments receive a 10-digit ACS Tracking number when they arrive in Cyprus.
ACS Courier delivery times and examples
Delivery time depends on the service, origin, destination and whether the address is considered a standard, island or difficult-to-access destination. ACS publishes indicative business-day delivery times rather than one universal promise for every package.
For basic Next Day domestic services in Greece, ACS lists approximately 1 business day within the same city, 1–2 business days within the same region, 1–2 business days to mainland destinations, 1–3 business days to island destinations and 1–5 business days to difficult-to-access areas. These are normal operational delivery times and can be affected by shipment conditions or service disruptions.
For international examples, ACS Europe 5 is described as a less urgent service to and from European Union countries with collection and delivery in approximately 2–8 business days. ACS Net Express is intended for urgent shipments to and from ACS international-network countries, including Cyprus, Albania and Bulgaria, but ACS does not state one single transit time that applies to every route between those countries.
Cyprus also has destination-specific considerations. ACS states that delivery to remote or difficult-to-access areas in Cyprus can require an additional 1–5 working days. Because exact transit time varies by route, ACS provides a Cost and Transit Time tool that can calculate the expected delivery time for a particular origin and destination.
How to contact ACS Courier about shipment issues
If your Tracking has stopped updating, a delivery is delayed or the package appears to have a problem, first check that you are using the correct 10-digit shipment number and review the latest tracking event. ACS recommends having the tracking number available whenever you contact customer service because it is needed to identify the shipment.
For shipments handled through ACS Greece, the official Customer Service Department can be reached at +30 210 8190000 or +30 211 5005000. ACS lists customer-service hours as Monday to Friday from 08:00 to 20:00 and Saturday from 08:00 to 15:00. Customers can also submit a request through the Contact section of the ACS website at any time.
ACS provides a formal claim procedure for issues such as delayed delivery, loss, damage, billing problems or service problems at an ACS location. Customers in Cyprus have separate local support channels, including the ACS Cyprus call center, while customers in other ACS markets should use the relevant local ACS website or service point for country-specific assistance.
Frequently asked questions about ACS Courier package tracking issues
Why is my ACS Courier tracking number not working?
Check that you entered the full shipment number correctly. Standard ACS shipment numbers are officially described as 10-digit numbers. A newly created shipment may also take some time to receive its first operational scan. If the number continues to produce no Tracking information, confirm it with the sender or contact ACS.
How many digits are in an ACS Courier tracking number?
ACS official documentation identifies the standard shipment number as a 10-digit number. The same 10-digit format is referenced for ACS Smartpoint Locker shipments and return-shipment codes.
Can I Track ACS Courier packages from Greece to Cyprus, Albania or Bulgaria?
Yes. ACS identifies Greece, Cyprus, Albania and Bulgaria as countries within its own network, and ACS Net Express handles urgent shipments to and from these international-network countries. Enter your ACS shipment number on 4Tracking to follow the available package tracking updates.
Why has my ACS Courier Tracking stopped updating?
A package may travel between ACS facilities without generating a new public event at every stage. Wait for the next operational scan and compare the shipment's progress with its expected delivery time. If the shipment remains unchanged beyond the expected transit period, contact ACS with the tracking number ready.
How long does ACS Courier delivery take in Greece?
For basic domestic Next Day services, ACS publishes indicative times of 1 business day within the same city, 1–2 business days within the same region or to mainland destinations, 1–3 business days to islands and 1–5 business days to difficult-to-access areas. Actual delivery depends on the shipment and route.
How long does ACS Courier take for international shipments?
There is no single international transit time for every destination. As one official example, ACS Europe 5 provides estimated collection and delivery within 2–8 business days for eligible European Union shipments. For shipments within the ACS network in Cyprus, Albania and Bulgaria, the exact time depends on the origin and destination and should be checked using ACS transit-time information.
Can I track several ACS Courier packages at once?
Yes. ACS's own Track and Trace page supports searches for multiple shipments, while 4Tracking can also be used to follow package tracking information by entering your shipment numbers as supported by the tracking page.
What should I do if ACS says my package was delivered but I cannot find it?
Review the Tracking information and check whether another person at the address accepted the shipment or whether it was redirected to an ACS service point or Smartpoint Locker. If you still cannot locate it, contact ACS customer service promptly and provide the 10-digit shipment number so the delivery can be investigated.
What should I do if my ACS Courier package is delayed, lost or damaged?
Contact ACS customer service with the tracking number and shipment details. ACS accepts requests and complaints concerning delayed deliveries, lost shipments, damage, billing problems and service issues, and its website provides a formal claim process when further investigation is required.
