We investigate anisotropic inflation within the single-field model featuring an intermediate scale factor. Our analysis reveals that the anisotropic nature of the Friedmann equations in this framework affects the slow-roll parameters, which in turn influence key perturbation parameters. Using a numerical approach, we derive constraints on the intermediate parameter β and the anisotropic parameter c. Our results show that the model is consistent with Planck2018TT, TE, EE+lowE+lensing+BK14+BAO data at 68% CL, for 0.84<β<1 and 7.34<c<27.7. At 95% CL the consistency holds for 0.77<β<1 and 7.17<c<28.9. The model is also consistent with Planck2018TT, TE, EE+lowE+lensing+BK18 +BAO data, for 0.91<β<1 and 8.00<c<27.4 (at 68% CL), and 0.88<β<1 and 7.40<c<28.8 (at 95% CL). Additionally, we examine the reheating phase using these constraints on constraints on β and c and determine the observationally consistent ranges for the number of e-folds and the temperature during the reheating phase
