GR Prefix and Three-Letter Location Code
Greek UN/LOCODEs begin with the two-letter country prefix GR, followed by a three-letter location identifier. For example, GRPIR identifies Piraeus and GRTHE identifies Thessaloniki.
Greece has 257 ports and terminals indexed in the Ecer Freight database and serves as a strategic gateway between European, Mediterranean, Black Sea and global shipping markets.

Greece combines major container gateways, energy and bulk facilities, ferry ports and island terminals. The figures below distinguish Ecer Freight indexed coverage from publicly reported national and port-level operating statistics.
How many seaports does Greece have?
Greece has 257 seaports and terminals indexed by Ecer Freight in its Greece port database as of November 2026. This is an indexed coverage count, not a legal classification of every Greek harbor.
What is the largest or busiest container port in Greece?
Piraeus is generally Greece’s leading container gateway by throughput and international liner connectivity. Its UN/LOCODE is GRPIR, while Thessaloniki, coded GRTHE, is the principal northern container gateway.
Which areas handle most Greek maritime freight?
The main freight concentrations are the Attica and Piraeus area, the Thessaloniki and northern Greece gateway, and western and central ports such as Patras, Volos and Eleusis. The Ecer Freight sample lists GRPIR, GRTHE, GRVLS, GRPAT and GRELE among these locations.
This indicative league table separates publicly reported container throughput from the broader Ecer Freight indexed port count. Rankings are global context rather than an official national ranking, and figures remain subject to port and statistical authority confirmation.

UN/LOCODE references help carriers, forwarders, customs teams and booking systems identify Greek maritime locations. A code should be checked against the operational port, terminal and transport document.
Greek UN/LOCODEs begin with the two-letter country prefix GR, followed by a three-letter location identifier. For example, GRPIR identifies Piraeus and GRTHE identifies Thessaloniki.
A city may appear under more than one operational reference in shipping systems. The sample includes GRVOL and GRVLS for Volos and GRTHE and GRSKG for Thessaloniki, so the exact booking or terminal instruction should be confirmed.
Cross-check the code with the UNECE UN/LOCODE resource and compare it with the searchable Ecer Freight port directory before issuing shipping instructions.
Transit times are indicative port-to-port ranges and may change with carrier schedules, transshipment, seasonality, customs clearance and inland delivery requirements.
Regular container services connect Greek gateways with North European hub ports and onward inland distribution networks.
Short-sea and feeder networks support trade with Italy, Spain, France, Türkiye and other Mediterranean markets.
Piraeus and other Greek gateways can serve Levant, Gulf and Red Sea connections through direct or transshipment services.
The eastern Mediterranean position of Greece supports Asia–Europe container flows, with schedules dependent on carrier rotations and transshipment arrangements.
The page combines first-party indexed coverage with public port, transport and trade references. Port-level operating figures can use different reporting boundaries, fiscal periods and definitions.
This Greece port guide was prepared from the Ecer Freight port database, public UN/LOCODE references, Greek statistical sources, European maritime statistics and port-authority information. Indexed coverage is reviewed with database updates, while time-sensitive port activity and trade-lane information are checked quarterly where public data are available.
