Classification of route numbers
Historic classification
When the bus system of Thessaloniki was first established in 1957 all lines were numbered from the eastern to the western routes starting with 1. This applied to all routes from 1 to 29. However, after 1979 the rest of the lines were numbered based on the date of their creation.

Nowadays, there is no official classification however unofficially the routes are classified as follows: trunk routes, urban routes (OASTH operated routes), metropolitan - regional routes (KTEL operated routes).
Lines 42, 43, 45, 59 and 60 are within Thessaloniki's urban area. Lines 52 and 72 are operated by OASTH despite being outside Thessaloniki's urban area.

List of routes
All routes operate in both directions unless detailed. Operatings hours and frequencies are based on OASTH's summer everyday schedule. NOTE: the operating hours and frequencies may defer during the weekend. Average frequencies also differ based on the time of the day, see OASTH's official site or the references for the exact times.
In 2023, the Transport Authority of Thessaloniki started operating 4 special temporary express lines until the "Flyover" road of Thessaloniki was complete, presumably in 2028.
^Lines 27A and 27B were abolished and replaced by line 56A
^Lines 28A and 28B were the same line, transition and return respectively, but they were denoted with different letters in order to make it easier for commuters to understand the line's sequence. The lines were merged into line 28 in 2024.
^Line 41 was abolished in 2010 when line 1 and 28 were expanded from the terminal station of Neapoli to the terminal station of Efkarpia.
^Line 57Y was established in 2020 in order to assist the medical staff of Nosokomeio Papageorgiou (Hospital) with more routes (specifically for the hospital's staff). The line was later abolished as it was identical with line 57.
