‘Checking In’: Definition, Meaning, and Examples

By Sophia Merton, updated on November 10, 2022

What does it mean if someone says they’re just ‘checking in’? What about when somebody says they’re ‘checking in’ at a hotel?

The phrase ‘checking in’ has a number of different meanings, including:

  • Confirming one’s arrival at a place where one is expected
  • Returning something that has been borrowed, as in a library book
  • Communicating with someone to provide a status update, to ask for a status update, or just to talk
  • Using a social media platform to report one’s location

What Does ‘Checking In’ Mean?

The term ‘checking in’ actually has a few different meanings. They are:

  1. Confirming one’s arrival at a specific location where one is expected (for example, a hotel, a doctor’s appointment, or a convention)
  2. Communicating with another individual in order to ask for or provide a status update or to simply to chat at a certain interval in time
  3. To return something while satisfying all requirements
  4. To self-report where you are through specific social media platforms

How ‘Checking In’ Is Used

You can usually understand which meaning is implied by the phrase ‘checking in’ or ‘check in’ depending on its context.

For example, if someone is talking about their itinerary for a trip and their arrival at an airport or a hotel, they are most likely using the first definition of ‘checking in’ listed above.

On the other hand, if your friend messages you online and says they’re “just ‘checking in,’” the meaning implied is definition number two on our list. In this use of the phrase, the implication is that they want to see how you are doing and what has been going on in your life. If you spoke to them recently, they might simply be asking how your day is going, while if it’s been some time since you spoke, they might be asking more generally about how things in your life are.

If your boss at your new job says that they are going to ‘check in’ periodically, they are implying that they will be contacting you (either in person, through the phone, or online, depending on what is standard in your office,) to see how you are settling in and to find out if you have any questions.

‘Checking in’ and ‘check in’ are also used in relation to returning a library book or something else you’ve rented or ‘checked out.’ For example, if a librarian asks if you’re planning on ‘checking in’ your overdue book, they are asking if you are ready to return it to the library’s circulation.

Finally, a number of social media platforms have ‘check-in’ features where you can report your location. For example, if you go to a hip restaurant in town, you can let your friends and followers know where you are by ‘checking in.’

The Origin of ‘Checking In’

The word ‘check' in itself has several different meanings– it can refer to:

  • A situation in chess where an opposing piece is directly threatening the king
  • A limit or stop; a control
  • A mark used to indicate something (for example, a checkmark)
  • A bill at a restaurant
  • A specific paper that orders a bank to pay money to a specific entity or person (such as those found in a checkbook)
  • A token used in gaming machines and gambling activities instead of cash
  • A small crack
  • A sports maneuver made by a player to remove another player from the play

As you can see, this is a versatile word indeed. It even has a definition specific to the sport of falconry– when a hawk forsakes its proper game and instead follows other birds.

Many of the ways that the word ‘check’ is used seem to have developed from the way that ‘check’ is used in chess, i.e., ‘to arrest, stop.’

The use of the phrases to ‘check in’ or ‘check out’ in relation to a hotel and other things, such as library books, dates back to at least 1909. ‘Check up,’ on the other hand, which is related to the meaning of ‘checking in’ refers to communicating for a status update, dates back to 1883.

Using the Google Books Ngram Viewer, we can see that the phrase ‘checking in’ was already in use in the early 1800s, but only nominally. It isn’t until around 1900 that the use of this phrase begins to increase, reaching a new high in the 1940s before plateauing until about 1980.

Sentence Examples of ‘Checking In’

Now that we have a better sense of the meaning and origin of ‘checking in,’ let’s look at some of the practical ways you might use the phrase in a sentence.

Confirming Your Arrival at a Location Where You Are Expected

If you are arriving at a hotel, you are commonly expected to stop by the front desk in order to let them know you are there, receive your room key, and potentially make arrangements for payment. Other common places you might ‘check in’ include the airport or a convention.

  • We are going to find a nice place to eat breakfast downtown before checking in at the hotel.
  • Last year, checking in at the convention on Friday was extremely chaotic, so I am going to arrive a day early to avoid the hassle.
  • When I was checking in at the gate for my flight, I was informed that there were mechanical issues and that the flight was indefinitely delayed.
  • The process of checking in at the conference seemed unnecessarily complex.

Returning an Item

When you take out a library book, rent a tool, or otherwise borrow something you are expected to return, it is generally said that you are ‘checking out’ the item. You are ‘checking in’ the object when you bring it back.

  • When you are ready to check in the table saw you are renting, you simply have to bring it back to the front desk.
  • If you are checking in those library books, would you mind returning my books as well?
  • As a security precaution, they are asking people to check in their personal items, including things like keys, wallets, and pocket knives.
  • The university library rents out laptops for students to use, but you have to check them in 24 hours later in order to avoid a hefty fine.

Communicating With Another Person to Provide or Ask For a Status Update

Perhaps the most common usage of the phrase ‘checking in’ in a casual conversation has to do with connecting with another person in order to talk or exchange a status update.

For example, your boss might say they are ‘checking in’ about a project with an upcoming deadline, or a friend might call and say they are just ‘checking in’ after you haven’t spoken in a little while.

  • I’ve been meaning to check in with you for weeks now, but I’ve been completely swamped at work.
  • Sally is planning on checking in on the development team twice a week to make sure they stay on schedule.
  • He wasn’t calling for any particular reason– he was just checking in.
  • I wanted to check in with you about your plan for the weekend. Are you planning on being at the office, or are you going to stay home?

In a related use, you can also ‘check in’ on something other than a person. For example, the morning routine of a pig farmer likely includes ‘checking in’ on his swine, while a pest control company might schedule appointments to periodically ‘check in’ on the property of a homeowner to make sure a mice infestation is still under control.
