Used to check something you once knew but have forgotten, asking another person or yourself. It is casual spoken Japanese; with superiors use 〜でしたっけ or 〜ましたっけ. A second use, often with よく〜たっけ, is fondly remembering the past.

Rather than adding っけ directly to the dictionary form, it is normal to insert んだ: 行くんだっけ. It is not used in formal writing.
미니 퀴즈

정답과 해설
정답: 1 だった
Huh, what kind of shop was this before? A noun takes だ or だった before っけ, so 何の店だったっけ is correct.
2すみません、次の会議は何日（ ）？
정답과 해설
정답: 3 でしたっけ
Excuse me, what date is the next meeting again? The polite form is でしたっけ. っけ does not attach to でしょう, だろう, or ます.
3鍵、どこに（ ）っけ。
정답과 해설
정답: 2 置いた
Where did I put my key again? The speaker is trying to remember a past action, so the た form 置いたっけ is correct. っけ does not attach to 置いて or 置き.
