SIP Trunk Greece — +30 Termination & DID Numbers
Greek numbers are ten digits with the area code built in, with no trunk prefix: Athens landlines begin 21 and mobiles 69. Tourism makes Greece a seasonal destination, and inbound demand from abroad peaks over the summer.
Overview
Routing calls to Greece
Most Greece traffic we see ends in Athens, Thessaloniki and Patras, Heraklion and Larissa. Each +30 prefix is mapped to at least two carriers, and we watch ASR, ACD and PDD per prefix so a degrading route is replaced before your agents notice.
EETT sets the Greece numbering plan, and our prefix tables follow it closely. Supported number types: geographic, national, mobile and toll-free. There is no trunk prefix to strip: send 30 followed by the national number as written.
Outbound termination to Greece starts as soon as your balance is topped up. Local DIDs are different: EETT rules usually require address and identity documents, which our team collects and checks before activation.
