My mom checked into her hotel and noticed a tiny blue dot sticker on the door. She’s freaking out—what does a blue dot mean?.

For example, if only one room on an entire floor has a strange dot and no one else’s door does, it’s reasonable to ask the front desk—calmly.

But even in those cases, 90% of the time, staff will say:

“Oh, that’s just a maintenance sticker. Sorry about that—we should have removed it.”

🏢 How Hotels Actually Use Stickers Behind the Scenes
To give a clearer picture, let’s explore how hotels organize rooms internally. Most hotels have systems such as:

🔹 Color-coded inspection dots
Blue = inspected
Yellow = needs attention
Green = ready for guest

🔹 Stickers for contractors
Cleaning crews, pest-control companies, and renovation teams may mark inspected areas and forget to remove labels.

🔹 Lost item indicators
