Surprise Call
Overview
A surprise call (Korean: 깜짝 통화) is an expression referring to a call made to or received from another party without prior notice, and it is used in various contexts such as broadcast and entertainment production techniques, corporate customer-contact marketing, and voice phishing prevention education. It carries both a positive nuance emphasizing intimacy and spontaneity and a double-sided nature of discomfort and wariness caused by unpredictable contact.

Definition and Etymology
'깜짝' (kkamjjak) is a native Korean word meaning a situation of being startled at an unexpected moment, and '통화' (tonghwa) refers to the act of speaking with someone by phone. The compound '깜짝 통화' intuitively expresses a call made without a fixed schedule or prior agreement. It is similar to the English 'surprise call,' but a characteristic of Korean usage is that it has often become fixed as a kind of proper noun, such as the name of a broadcast segment or event.
Use in Broadcasting and Entertainment
Segments such as 'surprise phone calls,' in which a host makes an impromptu call to a celebrity or acquaintance on a live radio show or variety program, have long been popular. The core production principle of such segments is that the flustered reactions of a person receiving a call at a completely unexpected moment create laughter and buzz. Recently, short and provocative 'surprise call reaction' clips on YouTube and short-form content have recorded high view counts and established themselves as a genre.
Marketing and Customer Service
Campaigns in which companies call customers without notice to express thanks or announce new products are also called surprise calls. 'Surprise calls' made only to customers of a certain tier are used as a means of emphasizing scarcity and specialness. However, when combined with random cold calls, the risk of being perceived as spam increases, so it is important to have caller ID display and prior consent procedures in place.
Distinction from Voice Phishing
Surprise calls and voice phishing look similar on the surface, but their purposes and contexts differ. A normal surprise call has a natural conversational context and does not demand money transfers, personal information, or app installation. On the other hand, if someone impersonates a financial institution or investigative agency, emphasizes urgency, and induces link clicks or installation of remote-control apps, voice phishing should be suspected. Recently, distinction has become even more difficult as caller ID spoofing and AI voice synthesis are combined.
Etiquette and Communication
A surprise call can be rude if it does not take the other person's situation into consideration. Calls outside working hours, repeated missed calls within a short time, and calls made without a text message place a burden on the other party. Therefore, it is recommended to state the purpose concisely in the first call and to convey the intention that, if a call is difficult, it can be replaced by a text message.
Recent Trends
In 2024–2025, with the spread of AI voice synthesis (deep voice) technology, new types of fraud in the form of 'surprise calls impersonating family members' have increased, creating an environment in which it is difficult to trust the other party based on a single call. In response, telecommunications companies and the financial sector have been introducing AI-based real-time voice detection, 'safe call passwords' between family members, and caller ID verification services one after another. Meanwhile, in broadcasting and short-form content, 'fake surprise call' entertainment formats using AI voices have instead become popular, and the need for media literacy education to distinguish the real from the fake is also growing.
