The invention relates to a reflective membrane for a license plate and a method for manufacturing the same and the license plate. The reflective membrane for the license plate comprises a resin layer, single glass microballoon layers arranged tightly and evenly, a focusing coating layer, a metal reflecting layer and an anti-sticking bottom layer, wherein the surface of the resin layer has a frosted structure. The method for manufacturing the license plate comprise the following steps: cutting the reflective membrane for the license plate into certain specifications, frosting the surface of the reflective membrane, and printing out required patterns or characters; and then selecting a license plate carrier, then sticking, flatly pressing and compounding the reflective membrane and the license plate carrier through a double-faced adhesive membrane, and finally manufacturing the license plate. The reflective membrane for the license plate and the production process for the reflective membrane are simple and mature, have strong controllability, and are convenient for large-scale industrialized production; and the process for manufacturing the license plate is convenient, has short period, has no pollution to the environment, and is convenient for field issue and implementation and popularization of personalized license plates.
