Service counter
A public desk in a government office where staff handle in-person transactions such as permits, licenses, records and payments. A service counter is usually staffed by several clerks who call people from one queue.
Queue number
The number a visitor receives on arrival at an office to mark their place in the queue, often with a letter prefix for the service, such as B-042. Staff call the number to a window and a display board shows which numbers are being served.
Appointment-only office
A government office that serves visitors only at booked times and does not take walk-ins. Offices move to appointment-only service to control lobby crowding and to give each visit a known amount of staff time.
Walk-in hours
Set hours when an office serves visitors without an appointment, in order of arrival. Offices often combine walk-in hours with appointment blocks so both kinds of visitors are served on the same day.
Service window
A numbered counter position, as at a DMV, where one clerk serves one visitor at a time. When a queue number is called it is sent to a specific window, so visitors know where to go.
