Methods, systems, and devices related to host identification for a memory system are described. A memory system may receive an index value from a host system that is associated with an identification of the host system. The memory system may identify one or more operating parameter associated with the index value based on receiving the index value. The memory system controller may configure the memory system to utilize one or more operating parameters associated with the index value based on identifying the operating parameters. The memory system may output an indication to the host system that the operating parameters associated with the index value are configured to be utilized by the memory system.
