What does caller mean?
'Caller' is a noun denoting a person who makes contact — most often by telephone, but historically also by visiting a home or office. The word is central to the language of broadcasting, where phrases like 'first-time caller' and 'long-time listener' are familiar staples of radio phone-ins, and to customer service, where identifying whether a caller is new, returning, or anonymous shapes how a conversation begins. The rise of caller ID transformed the term's cultural weight: what was once an unknown voice on the line can now be named before it is answered, making 'unknown caller' a modern synonym for uncertainty itself. In Scottish and northern English speech, 'caller' has an older, quite different life as an adjective meaning fresh or newly caught — 'caller herring' being the classic example. As a noun it is unremarkable but indispensable, a workhorse word for anyone describing who is on the line or at the door.
A person who makes a telephone call, or who visits a place such as a house or office.
"The switchboard logged every caller's number."
In broadcasting contexts, terms like 'first-time caller' are standard.
In Scottish and northern English usage, fresh, cool, or recently caught or arrived.
"They bought caller mackerel straight off the quay at Fraserburgh."
Regional and now somewhat traditional; best known in phrases like 'caller herring'.
Standard plural; used when referring to multiple callers, e.g. on a phone line or waiting list.
"The station received hundreds of callers after the announcement."
Before caller ID existed, answering the phone meant every caller was a mystery — the phrase 'first-time caller, long-time listener' became radio shorthand for that era of anonymous voices.

Etymology of caller
'Caller' derives from the verb 'call', which entered English most likely through Old Norse 'kalla' during the Viking Age, displacing or supplementing native expressions. From this root come relatives such as 'recall' and the derived noun 'calling'. The noun 'caller' simply names the agent who performs the action of calling, and its visit-based sense reflects the older British practice of formally 'calling on' someone at their home.
How caller is actually used
Mostly neutral register, common in broadcasting, customer service, and everyday speech. In Scottish and northern English usage, 'caller' also survives as an adjective meaning fresh or newly arrived, especially applied to food such as 'caller herring'.
