| `AT` | personnel administratif et technique | administrative and technical staff |

## About this plate

THE AT SERIES, administrative and technical staff of diplomatic missions. Switzerland is unusual in giving A&T staff their own SIGN at all: most jurisdictions fold them into the diplomatic or the ordinary series.
