In this paper, by using the quasi-normal frequencies for non-rotating BTZ black hole derived by Cardos and Lemos, also via Bohr-Sommerfeld quantization for an adiabatic invariant, I=∫[(dE)/(ω(E))], which E is the energy of system and ω(E) is vibrational frequency, we leads to an equally spaced mass spectrum. The result for the area of event horizon is An=2π√{[(nm ħ )/(Λ )]} which is not equally spaced, in contrast with area spectrum of black hole in higher dimension.
