About Bus Line Numbers and Letters

AC Transit's numbered lines serve the East Bay.

Lines 1–299 operate normal hours. Normal hours are, at a minimum, the commute periods, 6 a.m. – 9 a.m. and 4 p.m. – 6 p.m., weekdays. Almost all operate all day on weekdays and many operate weekday evenings and weekends as well. Lines 200-299 serve the areas of Fremont and Newark, while other lines serve other parts of the East Bay from Richmond to Hayward.

Lines 300–399 do not operate during the commute period. They operate at other times of the day: for example, mid-days only, weekends only, or evenings only. Some lines operate only a few days per week (for example, Tuesdays and Thursdays).

Lines 600–699 are timed to match the instruction hours of local schools, and operate only when schools are in session. They may have altered schedules when local schools have minimum day or alternative schedules. These lines are open to all passengers at regular fares.

Lines 800–899 are All-Nighter lines, operating from 1 a.m. – 5 a.m. daily. Some may operate somewhat earlier or later (especially on weekends).

Lettered lines (A-Z) are Transbay routes, connecting the East Bay to San Francisco or the Peninsula.
