GR Prefix and Three-Letter Port Code
Greece uses the ISO 3166-1 alpha-2 prefix GR. A UN/LOCODE normally combines GR with a three-letter location identifier, such as GRPIR for Piraeus, GRTHE for Thessaloniki and GRPAT for Patras.
Greece has 257 ports and terminals indexed in the Ecer Freight database and serves as a strategic maritime gateway between the Eastern Mediterranean, Europe, the Black Sea and global trade lanes.

Greece combines large container gateways, multipurpose commercial ports, ferry terminals and island facilities. The figures below distinguish Ecer Freight’s indexed port coverage from national and port-authority statistics.
How many seaports does Greece have?
Greece has 257 seaports and terminals indexed by Ecer Freight in its country port database as of October 2026. This is an indexed database coverage figure, not a statutory count of every harbour or marina.
What is the largest or busiest cargo port in Greece?
Piraeus, UN/LOCODE GRPIR, is generally Greece’s leading container and gateway port by cargo activity. Thessaloniki, coded GRTHE, is the principal northern Greek commercial and container gateway.
Which areas handle most of Greece’s freight?
The Attica and Saronic Gulf cluster around Piraeus, Eleusis and Aspropyrgos handles a major share of gateway and industrial cargo, while Thessaloniki serves northern Greece and Balkan hinterlands. Patras and Volos provide important regional and ferry-linked freight roles.
The table uses the most commercially active port records in the Ecer Freight sample. World ranking and 2025 throughput are shown only where a comparable, publicly reported 2025 container series is available; port-level reporting conventions can differ.

Greece uses the ISO 3166-1 alpha-2 prefix GR. A UN/LOCODE normally combines GR with a three-letter location identifier, such as GRPIR for Piraeus, GRTHE for Thessaloniki and GRPAT for Patras.
A city-level location and a terminal or operational record may appear as separate entries. For example, Thessaloniki is represented in the sample by GRTHE and GRSKG, so the exact code should be matched to the booking, bill of lading and carrier instructions.
Verify the location against the UNECE UN/LOCODE directory and cross-check the operational record in the Ecer Freight port directory before quoting or filing shipping documents.
Routing, transhipment, equipment availability and sailing schedules are subject to carrier confirmation, seasonal conditions and the selected Greek gateway.
Containerised exports and imports commonly move through Piraeus and connect with Northern European hub ports.
Short-sea and feeder services link Greek gateways with Turkey, Cyprus, Egypt and Levant markets.
Piraeus is a major Mediterranean entry point for Asia–Europe container flows, with onward feeder and inland distribution options.
Patras and other western ports support ro-ro, ferry and short-sea flows between Greece, Italy and the Adriatic region.
Port coverage, code presentation and commercial descriptions are maintained separately from official throughput league tables. Figures are reviewed against available public releases and should be confirmed for a live shipment.
Greece has 257 seaports and terminals indexed by Ecer Freight as of October 2026. The figure represents database coverage and does not necessarily equal the number of legally designated ports, harbours or marinas.
Piraeus, UN/LOCODE GRPIR, is generally the main container gateway in Greece. Its role and current throughput should be confirmed with the carrier or port authority for the relevant sailing period.
The Ecer Freight sample lists Piraeus as GRPIR. Shipping documents should still be checked against the carrier booking and the latest UNECE location-code data.
Thessaloniki, listed as GRTHE, is the principal northern Greek commercial gateway and supports cargo flows to northern Greece and nearby Balkan markets.
The Attica and Saronic Gulf cluster, northern Greece around Thessaloniki, western Greece around Patras, and Crete around Heraklion are key areas. Volos and Alexandroupolis also support important regional or specialised cargo roles.
The Ecer Freight country-page snapshot is October 2026, while the most recent complete statistical reference year is 2025. Port schedules, berth conditions, throughput and carrier rotations remain subject to periodic revision.
FCL and LCL rate searches can be made through the relevant Ecer Freight quotation pages. A usable request normally includes origin port, destination, cargo description, container or volume details, weight and expected shipping date.
