Numbering Structure and Overlays
Greek fixed-line numbers typically consist of 10 digits in total, including the trunk prefix '0'. The NDC (2323) is followed by a 5-digit subscriber number, making the complete national significant number (NSN) 10 digits (including the leading '0'). As of the latest EETT updates, there is no overlay code for this area; the 2323 code is exclusively used for Sidirokastro. However, subscribers may have the option to retain their numbers when switching providers, thanks to number portability regulations.
