Since masking of quantum information was introduced by Modi et al. in [PRL120, 230501 (2018)], many discussions on this topic have been published. Inthis paper, we consider relationship between quantum multipartite maskers(QMMs) and quantum error-correcting codes (QECCs). We say that a subset $Q$ ofpure states of a system $K$ can be masked by an operator $S$ into amultipartite system $\H^{(n)}$ if all of the image states $S|\psi\>$ of states$|\psi\>$ in $Q$ have the same marginal states on each subsystem. We call suchan $S$ a QMM of $Q$. By establishing an expression of a QMM, we obtain arelationship between QMMs and QECCs, which reads that an isometry is a QMM ofall pure states of a system if and only if its range is a QECC of anyone-erasure channel. As an application, we prove that there is no an isometricuniversal masker from $\C^2$ into $\C^2\otimes\C^2\otimes\C^2$ and then thestates of $\C^3$ can not be masked isometrically into$\C^2\otimes\C^2\otimes\C^2$. This gives a consummation to a main result andleads to a negative answer to an open question in [PRA 98, 062306 (2018)].Another application is that arbitrary quantum states of $\C^d$ can becompletely hidden  in correlations between any two subsystems of the tripartite system$\C^{d+1}\otimes\C^{d+1}\otimes\C^{d+1}$, while arbitrary quantum states cannotbe completely hidden in the correlations between subsystems of a bipartitesystem [PRL 98, 080502 (2007)].
