TBC most often means “to be confirmed.” In a text, email, or calendar invite, it tells you a detail such as a date, time, or venue is planned but not final. In storytelling and social media captions, TBC can also mean “to be continued.”
This guide explains both meanings, where each one appears, and how to reply so nobody ends up confused.
So, What Does TBC Actually Mean?
TBC is an abbreviation for “to be confirmed,” used when a detail has been proposed but not yet finalized.
The message behind it is simple: “This is the current plan, but don’t lock it in.” Compare these examples:
- “Dinner at 8 pm, TBC.” (8 pm is the likely time, but it could change.)
- “Meeting room B, TBC.” (A room is pencilled in, not booked.)
- “Delivery Friday, tbc.” (Friday is the estimate, not a promise.)
The second meaning, “to be continued,” turns up when a story, thread, or conversation is unfinished. A creator might write “TBC” at the end of a video series or a long post. A friend might text “Wait till you hear what happened next, TBC” to signal they’ll explain later.
How to tell which one you’re reading:
| Clue | Likely meaning |
| Sits next to a date, time, price, or place | To be confirmed |
| Appears at the end of a story, caption, or chapter | To be continued |
| Follows a plan or schedule item | To be confirmed |
| Follows a cliffhanger or unfinished thought | To be continued |
A Brief Background: Where Did TBC Come From?
The two meanings have separate histories. “To be continued” comes from serialized fiction. Newspapers and magazines published novels in installments, and each one ended with a note promising more. Early film serials and later television cliffhangers kept the habit going.
“To be confirmed” comes from administrative and scheduling language. Organizers of timetables, sports fixtures, and conferences needed a short way to mark unsettled details. Dictionaries such as Collins and Oxford list it as a notice-style abbreviation, and it is especially common in British English. American writers more often reach for TBD or TBA.
Text messaging and social media then pushed both meanings into everyday slang, where they are often typed in lowercase (“tbc”) without punctuation.
How TBC Plays Out Across Different Platforms
TBC keeps the same core meaning on every platform, but its tone changes with the setting.
- WhatsApp and iMessage: Mostly “to be confirmed,” used for casual plans like meetups and lifts.
- Instagram and TikTok: Often “to be continued,” attached to multi-part videos or story posts.
- Snapchat: Either meaning, usually inside quick, informal replies.
- Email and Slack: Nearly always “to be confirmed,” in a neutral, professional tone.
- Calendars and event listings: “To be confirmed,” attached to a venue, speaker, or start time.
Because the same three letters serve two purposes, context does the work. If you’re unsure, ask.
TBC in Technical Fields: Physics, Medicine, and Aviation
Outside everyday messaging, TBC can be a specialist abbreviation with a different meaning entirely.
- Aviation and engineering: TBC can stand for thermal barrier coating, a ceramic layer applied to turbine blades and combustion parts so they survive extreme heat. Airline and airport schedules also use TBC in the ordinary sense for flight details not yet fixed.
- Medicine: In some countries, especially where Spanish, Italian, or Portuguese medical terminology is common, TBC abbreviates tuberculosis. English-language clinical documents usually write TB instead.
- Physics and lab work: Research teams use TBC in the standard “to be confirmed” sense for results awaiting verification, and in some documents the letters belong to a project-specific term. Always check the document’s glossary.
Rule of thumb: in a technical document, look for a definitions list before assuming what TBC means.
The Funny Side of TBC in Online Culture
In online culture, TBC works as a comedic cliffhanger, a way of teasing that a story is unfinished.
People use it to build suspense over trivial things: “I just walked into the wrong wedding. TBC.” It also shows up as a joke about commitment, as in a friend who replies “TBC” to every invitation, meaning “maybe, but don’t count on me.”
Memes lean on the second reading too. A dramatic freeze-frame with a caption in an old-style font is a familiar way of signaling “to be continued.” The abbreviation lets a poster get the same punchline in three letters.
TBC Meaning in Business
In business, TBC marks any commercial detail that is expected but not contractually or operationally final.
Common examples include:
- Delivery dates on quotes and order confirmations
- Pricing on proposals awaiting supplier figures
- Speaker names on conference agendas
- Launch dates on product roadmaps
- Attendee counts on booking forms
A TBC label keeps documents moving without pretending every answer is known. It is an honest placeholder, and it gives the reader a cue to check back.
Note on other TBC meanings: TBC is also the name of some organizations, such as TBC Bank in Georgia and Taegu Broadcasting Corporation in South Korea. If a company name appears next to the letters, it is probably a brand, not an abbreviation.
TBC Meaning in Work
At work, TBC in a message means the sender expects to give you a firm answer later.
Everyday workplace uses look like this:
- Meeting invites: “Kick-off call Thursday, time TBC.”
- Task lists: “Owner: TBC” means nobody has been assigned yet.
- Shift rosters: “Cover for Saturday TBC” signals a gap still being filled.
- Status updates: “Budget approval TBC” means the sign-off hasn’t happened.
Teams that use TBC well pair it with a follow-up point, such as “TBC by Wednesday.” That turns a vague placeholder into a commitment.
TBC in Business: More Than Just “We’ll Confirm Later”
TBC can also carry information about risk, priority, and responsibility.
A TBC item tells a reader that the plan depends on something outside the writer’s immediate control. Typical dependencies include a client’s approval, a supplier’s stock, a regulator’s decision, or a colleague’s availability.
In project management, a list of TBC items works like an informal risk register. A project manager reviewing a schedule with six TBC entries knows where delays are most likely to appear. Sales teams use the same signal on quotes: “price TBC” warns the customer that final costs may shift.
A related official use comes from the British Board of Film Classification, which uses “tbc” to mean “to be classified” for films awaiting a rating.
TBC in Hospitals: What It Means at the Clinical Level
In hospitals, TBC generally means a clinical decision or result is pending and has not been verified.
You may see it on:
- Appointment letters: “Clinic time TBC” means the slot is not yet allocated.
- Test records: A result marked TBC is awaiting confirmation or a repeat sample.
- Discharge planning: “Discharge date TBC” depends on how the patient recovers.
- Diagnoses: “Diagnosis TBC” means suspected but not confirmed by testing.
TBC on a medical document does not indicate a bad result. It only means the information is incomplete. Patients who see it should ask the care team what is pending and when it will be finalized.

What’s the Difference Between TBC, TBD, and TBA?
TBC, TBD, and TBA are all placeholders, but they differ in how much has already been decided.
| Abbreviation | Full form | What it signals | Example |
| TBC | To be confirmed | A detail exists but may change | “Venue: Hall A (TBC)” |
| TBD | To be determined | Nothing has been decided yet | “Venue: TBD” |
| TBA | To be announced | It may be decided, but isn’t public yet | “Guest speaker: TBA” |
In short: TBC means “probably this, but not certain,” TBD means “we don’t know yet,” and TBA means “we know, but we’re not saying yet.” Usage varies by region and industry, and some writers treat the three as interchangeable, so context matters.
How to Respond When Someone Sends You “TBC”
The best reply to TBC acknowledges the uncertainty and sets a way to finalize it.
Here is a simple approach:
- Note the current detail. “Got it, Friday at 7 for now.”
- Ask for a deadline. “When do you think you’ll know?”
- Keep your own plans flexible. Avoid non-refundable bookings until the detail is confirmed.
- Follow up. If the promised date passes with no update, send a polite nudge.
Sample replies:
- Casual: “No worries, ping me when it’s locked in.”
- Professional: “Thanks for the update. Could you confirm by Wednesday so we can finalize the booking?”
- For “to be continued”: “Okay, you can’t leave me hanging. Finish the story!”
TBC as a Trust Signal
Used honestly, TBC builds trust because it tells people exactly how reliable a detail is.
Saying “TBC” is better than stating a guess as fact. It shows the writer is being transparent, which readers value. The habit only works if it is followed through: a TBC that never gets resolved trains people to ignore your updates.
Three habits make TBC a credible signal:
- Use it only when a detail is genuinely unsettled.
- Say what the item depends on.
- Update it as soon as the answer arrives.
