Greece has a national telephone numbering plan with ten-digit telephone numbers. The first digit represents the type of service. 1 is used for short codes, 2 for geographical numbers (3 and 4 are reserved for that purpose too), 5 is used for inter-network routing purposes (non-dialable codes) and VPNs, 6 for mobile services, 7 is reserved for universal access numbers (not active), 8 for reduced-fee services (like 800 toll-free, 801 local call, 89 dial-up and data services), 9 is used for premium rate services (901 for general purpose and 909 for adult-only services). All dialable numbers are ten digits, except for short codes (3–5 digits in the 1 range), 807-XXXX (seven digits) used for calling card access codes, and numbers in the 5 range, used for routing purposes and not dialable by end-subscribers.
