What Does TBA Stand For?

What does TBA stand for, and what does it promise?

Each letter is one word: T for to, B for be and A for announced. The key word is announced. It suggests the answer may already exist inside the organization, or will soon, and the public will hear it once it is ready to share.

That sets TBA apart from a plain blank. A blank could mean someone forgot. TBA says the gap is known and on purpose. Because you say each letter, it is an initialism. A side by side look in acronym vs abbreviation shows why schedulers' shorthand like TBA lands in that group.

Where TBA shows up

• Sports schedules: "Game 7, if needed, time TBA." The league will set the time once it knows whether the game is needed and which network carries it.
• College course listings: "Instructor: TBA" or "Room: TBA" means the school has not yet assigned that person or space.
• Concerts and festivals: "More artists TBA" signals a lineup that is still growing.
• Work meetings: "Location TBA" in a calendar invite means watch for an update.
• Book and show releases: "Release date TBA" means a date is coming but not public.

TBA, TBD and TBC compared

These three look and work alike, and people often swap them. There is a small but useful difference.

So "speaker TBD" means the team is still choosing, "speaker TBA" means they may have chosen but are not saying, and "speaker TBC" means a name is penciled in. In casual American use, TBA and TBD are often treated as the same thing, and readers will understand either.

Other things TBA can mean

A few other meanings appear in specific fields, and the setting nearly always makes them clear.

• To be arranged: common in college catalogs for courses with times set later, such as an independent study.
• To be advised: used in some offices, travel notices and military messages. TBA in this sense is close to "we will tell you."
• Tires, batteries and accessories: a car industry term for the parts and add ons sold at service centers.

If you see TBA next to a date, time, room or name, it nearly always means to be announced or to be arranged. Both point to the same idea: the detail is coming.

Using TBA in writing

TBA is fine in schedules, tables, flyers and quick notes, where space is short. In a formal letter or article, it reads better to write the phrase out: "The date will be announced next week."

• Three capitals, no dots, is the modern habit.
• Use "a TBA," since T is said "tee."
• Place it right where the missing detail would go: "Time: TBA."
• When you can, add when the answer will come: "Room TBA by Friday."

A related label you will see on the same kinds of flyers is ETA, estimated time of arrival. On invitations, RSVP asks you to reply, even when the place is still TBA. For more letters people see every day, try the famous acronyms list.
