In this work, inspired by the observation of charmoniumlike Z_c⁺(4200)% , we study the photoproduction of charged charmoniumlike Z_c⁺(4200) with an effective Lagrangian approach and the Regge trajectories model. The numerical results indicate that the Reggeized treatment can lead to a lower total cross section of the Z_c⁺(4200) photoproduction and the peak position of cross section was moved to the higher energy point when the Reggeized treatment was added. {Moreover, using the data from the COMPASS experiment and presented theoretical predictions, an upper limit of the decay width of Z_c(4200)→J/ψπ is estimated.} The relevant results not only shed light on the further experiment of searching for the charmoniumlike Z_c(4200) state via meson photoproduction, but also provide valuable informations for having a better comprehension of the nature of charmoniumlike Z_c(4200) state.
