In combination, an identifier assembly is mounted to a tubular of a drill string to uniquely identify the tubular. The identifier assembly is provided with a radio-frequency-identification tag having a unique identification code stored therein, and means for mounting the radio-frequency-identification tag to the tubular such that the radio-frequency-identification tag is disposed outside of an arcuate external perimeter of the tubular.
