ACS Courier Tracking

ACS Courier tracking lets you follow a parcel, document, or cash-on-delivery (COD) order handled by ACS, the largest courier company in Greece, from the moment it is picked up until it reaches your door, an ACS branch, or an ACS Smart Point locker. Paste your ACS voucher number into the tracker on this page to see the latest scans in one place, whether the shipment is moving across Athens, travelling to a Greek island, or crossing a border into the European Union.

ACS Postal Services S.M.S.A. was founded in 1981 and handles roughly 54 million shipments a year across its courier and postal operations, serving more than 30% of all business-to-consumer e-commerce parcels in Greece. This guide explains how to read your ACS tracking number, what each tracking status means, how long domestic and EU delivery takes, how returns and customs work, and which marketplaces rely on ACS for the last mile. Every number format and delivery estimate below is drawn from ACS service pages and corroborating sources.

ACS Courier Tracking Number Format

A standard ACS Courier tracking number is a 10-digit numeric voucher code made up of digits only, with no letters, spaces, or hyphens (for example, 1234567890). ACS calls this number the voucher or AWB (air waybill) number, and it is printed on the shipping receipt the sender receives at the counter or generated in the order confirmation when a store ships your purchase. This is the number to paste into the tracker on this page.

Because the ACS voucher is a private courier reference rather than a Universal Postal Union S10 code, it does not carry the two-letter prefix or the country-code suffix you see on national-post items. A typical Greek national-post number from ELTA Hellenic Post tracking ends in the letters GR, while an ACS number is a plain string of ten digits. If your reference has letters in it, you are most likely holding either a national-post number or a seller order ID, not the ACS voucher.

You will usually find the ACS voucher number in one of three places: on the paper voucher attached to the parcel, in the dispatch or shipping-confirmation email from the online store, or inside your account on the marketplace where you placed the order. When ACS creates a return, it issues a brand-new 10-digit return voucher, so the outbound parcel and the return parcel each have their own separate tracking number.

One point that confuses many shoppers is the difference between a seller order ID and the ACS voucher. An order reference from a store such as Amazon tracking or AliExpress tracking is not the same as the 10-digit number ACS assigns once the parcel enters its network. Use the order ID inside the retailer account to find the ACS carrier reference, then track that voucher number here.

ACS Courier Tracking Number Example

The table below lists the ACS reference formats you are most likely to encounter, with the typical length and what each one indicates. ACS uses a single numeric voucher format for shipments, so the main thing to watch is whether you are holding the ACS voucher or a different reference entirely.

If you bought from an overseas marketplace, an inbound item may first travel under a tracking number issued by the origin carrier, such as a Bulgaria Post tracking number for a parcel routed through the Balkans, before ACS takes over the final delivery inside Greece. Both numbers describe the same parcel; the ACS voucher reflects the last domestic leg.

ACS Courier Tracking Status Guide

ACS Courier tracking statuses follow your parcel through pickup, sorting, transport, and final delivery, with extra steps for COD orders and cross-border shipments. The table below explains the events you are most likely to see and what each one means for your item.

What to Do If an ACS Courier Parcel Is Delayed or Not Updating

An ACS tracking page that has not updated for a day or two usually means the parcel is moving between scan points rather than that it is lost, because ACS records events at handover points rather than continuously. Domestic parcels in Greece are typically delivered the next business day, so a short gap is normal, especially over weekends and public holidays.

If your number shows no movement, first confirm you are tracking the ACS voucher and not the seller order ID, since the two look very different. Allow extra time during peak periods such as the Christmas season and major sales events, when parcel volumes rise sharply. For an EU shipment handled with GLS, the tracking may pause while the parcel crosses the border and the partner carrier takes over. If a domestic parcel is genuinely overdue, contact ACS customer service on +30 210 81 90 000 with your 10-digit voucher number, or ask the sender to open an inquiry with the originating ACS branch.

ACS Courier Services and Delivery Times Compared

ACS Courier offers a tiered range of services from next-day domestic delivery to EU cross-border parcels, each with its own speed and coverage. The comparison below summarises the main services and their typical delivery windows.

For international shipping, ACS sets a maximum total weight of 50 kg per shipment, and its EU services are run in cooperation with GLS and other established international carriers. COD courier services can be paid either by the sender or the recipient, and the collected amount is deposited to the sender, which is why COD remains central to Greek online retail.

ACS Courier Delivery and Transit Times Across Greece

Within Greece, ACS delivers to all major cities including Athens, Thessaloniki, Patras, Heraklion, Larissa, and Volos, with next-business-day service to most postcodes and same-day delivery within many city areas. Deliveries between the two largest cities, Athens and Thessaloniki, are generally completed within one business day.

ACS reaches mainland addresses and the Greek islands through a network of more than 600 service points across Greece, Cyprus, Albania, and Bulgaria, complemented by its ACS Smart Point locker and shop network. Island and remote-area deliveries can take an extra day depending on ferry and transport schedules, but the same voucher number tracks the parcel the whole way.

Recipients can choose how to collect a parcel: home or office delivery, pickup from a local ACS branch or partner shop, or collection from an ACS Smart Point locker available around the clock. The locker network has expanded quickly: by 2025 ACS operated more than 470 automated parcel lockers with over 13,000 compartments at more than 360 locations, concentrated in Athens and Thessaloniki.

ACS Courier Returns and Cash on Delivery for Online Orders

ACS provides a structured returns service that lets shoppers send part or all of an order back to the seller through the ACS network within the retailer's return window. When a return is booked, ACS generates a new unique 10-digit return voucher, so the return parcel is tracked independently of the original delivery. This reverse-logistics service is one reason many Greek online stores use ACS as their default carrier.

Cash on delivery is a defining feature of the Greek e-commerce market, and ACS handles COD at scale. The courier collects the order value from the recipient at the doorstep or pickup point and then deposits the amount to the sender, typically by automatic bank transfer. Because a large share of Greek shoppers still prefer to pay on receipt, reliable COD handling is a core part of the ACS service rather than an add-on.

Which Countries Does ACS Courier Deliver To?

ACS Courier is primarily a domestic Greek operator that also runs cross-border services to the European Union and, through partners, to destinations worldwide. Its own branch network spans four countries, Greece, Cyprus, Albania, and Bulgaria, while international parcels beyond that footprint are carried in cooperation with GLS and other global carriers.

Domestically, ACS covers the whole of Greece, from the Athens metropolitan area and Thessaloniki to regional cities and the islands, through 600-plus service points and its Smart Point network. For EU shipments, the ACS Europe Economy and Large Parcel services hand parcels to GLS for delivery across the continent, with the destination country's local carrier completing the final leg.

• Domestic: Athens, Thessaloniki, Patras, Heraklion, Larissa, Volos, and the Greek islands.
• ACS regional network: Cyprus, Albania, and Bulgaria, where ACS operates its own service points.
• Europe: Germany, France, Italy, the Netherlands, and other EU destinations via GLS.
• Worldwide: Other regions through partner international carriers.

Because ACS works alongside national posts and regional couriers, an item to or from a neighbouring country may pass through another operator at one end. Parcels to and from Cyprus often connect with Cyprus Post tracking, while domestic Greek competitors that you may see on the same routes include ELTA Hellenic Post and private couriers such as Geniki Taxydromiki and Speedex.

ACS Courier Customs and VAT on Inbound Parcels

Parcels arriving from outside the European Union are subject to Greek import VAT, charged at the standard rate of 24%, before ACS or the handling carrier releases them for final delivery. Goods moving within the EU are not subject to customs because of the single market, which is why an EU parcel handled by ACS and GLS clears without an import charge.

Many large marketplaces now collect EU VAT at checkout for goods valued under 150 euro through the Import One-Stop Shop (IOSS) scheme, which means the parcel is marked as VAT-paid and is released without an extra charge on arrival. When VAT has not been prepaid, the recipient may need to settle the import VAT and any handling fee before the parcel is delivered or made available at an ACS Smart Point.

"ACS handles more than 30% of all business-to-consumer e-commerce parcels in Greece and operates a blended Smart Point network of franchised shops, lockers, and parcel kiosks." (Greek logistics market analysis, 2025-2026.)

What Is ACS Courier and How Large Is Its Network?

ACS, legally ACS Postal Services S.M.S.A. and originally founded in 1981 as ACS Air Courier Services International, is the largest courier company in Greece and a member of the Athens-listed Quest Group (Quest Holdings). Over more than four decades the company built its position through continuous expansion and investment in sorting, transport, and last-mile technology, and it now processes around 54 million shipments a year.

The company operates more than 600 service points across Greece, Cyprus, Albania, and Bulgaria, plus an ACS Smart Point network that the market estimates at over 850 pickup locations blending franchised shops, lockers, and parcel kiosks. Its automated locker estate alone passed 470 machines with more than 13,000 compartments at over 360 sites by 2025, one of the largest parcel-locker networks in Greece.

In October 2024, GLS, the pan-European parcel carrier owned by International Distributions Services, acquired a minority stake in ACS and holds contractual options to buy the remaining shares. The tie-up strengthens ACS's cross-border reach into the rest of Europe while keeping its dense Greek domestic network at the centre of its business. ACS also provides supporting services such as money transfer in partnership with MoneyGram.

ACS Courier Marketplace Collaborations and Online Shopping Deliveries

ACS Courier is the centre of gravity of Greek parcel logistics, delivering for both domestic marketplaces and international platforms whose parcels arrive in Greece. With more than 30% of the country's B2C e-commerce parcels moving through its network, ACS is the default carrier for a large share of Greek online orders.

The most important domestic partnership is with Skroutz, the number-one marketplace in Greece, which offers over 26 million products from around 9,000 partners. Outside the Attica and Thessaloniki areas, Skroutz marketplace orders commonly default to ACS for last-mile delivery, and a newer agreement lets Skroutz shoppers collect orders not only from Skroutz Points but also from ACS branches and Shell service stations. ACS also carries orders for many independent Greek online shops that integrate its voucher and COD systems at checkout.

For cross-border shopping, ACS frequently completes the final delivery of parcels ordered from global marketplaces. Inbound orders from Amazon order tracking and AliExpress order tracking, along with fast-fashion and budget platforms such as Shein and Temu, are often handed to ACS or its EU partner GLS for delivery to Greek addresses and Smart Points. When VAT has been collected at checkout through IOSS, these parcels clear customs without an extra charge; when it has not, the import VAT is settled before the parcel is released.
