I did 39 artboards, but the counter missed the 38, counting from 37 to 39.

I created a new file with 3 artboards, but they are numbered 1, 2, and 4

also, they are created too close together so the "title" for the "04-Artboard 4" is IN the Artboard 1!

Same here, I have no page 99 and two pages 100.

The number sequence is duplicated when I have multiple artboards — for example, the number “25” appears twice. This issue also occurs in my other projects. Please look into this bug.

Even had this happen opening an old file. Like years old. It duplicated 4 & 6.

Still an Issue. Even with small numbers of artboards. I have 4 and it's 1,2,4,4.
Many have said it has to do with lots of artboards. Not my case. I see this all the time under 10 as well.

In Adobe Illustrator 2025, the Artboards panel shows a numbering inconsistency. Artboard 41 is missing from the sequence. The panel jumps from artboard 40 directly to 42, and there is no artboard corresponding to number 41 on the canvas.

Steps to Reproduce:

Open Illustrator 2025 on macOS.

Create a document with multiple artboards (more than 30).

Duplicate one artboard many times (e.g., “Artboard 8 copy”).

Open the Artboards panel and check the numbering.

Notice the numbering skips from 40 to 42.

Expected Result:
Artboard numbering should be continuous (40, 41, 42, etc.), and each number should match a visible artboard.

Actual Result:
Number 41 does not exist. The panel skips directly from 40 to 42.

Impact:

Confusion when organizing and referencing artboards.

Errors when exporting by artboard ranges (e.g., 39–42).

Complicates collaboration across teams.

Environment:

Adobe Illustrator 2025

macOS

File with more than 40 duplicated artboards

Evidence:
Screenshots attached showing the panel with missing number 41.

Duplicate numbers of the artboards... (in my case numbers 19 and 26)

I'm seeing an issue where artboards are not numbered correctly. Its skipping 5 and then sometimes additional numbers further down the list. This isn't a huge deal for using Illustrator, but when exporting as a PNG it now tries to save a "filename-6" and then it saves the next "6" artboard over the first one.

Related, this has been a consistant issue for years, when renaming artboards it frequently changes the name of the artboard to either blank or a generic "Artboard." It seems to happen most often when tabbing to each artboard to rename but sometimes it happens even when renaming them individually. Today I had one where the first three artboards were fine when I saved, but when I reopened them they had reverted to "Artboard 1"

I think the space in Illustrator is less than in Photoshop. When we design, we often have to make it as large as 50 feet / 100 feet. Which is problematic when done in Photoshop. If we do it in Illustrator, the work is faster but it has to be done in inches and cannot be done in actual size. If Illustrator has space like Photoshop, it will be good for everyone. There, we can easily make a 100-foot design. Another problem is when we prepare a PDF file in a small size, later when the file is ready, while checking it, we see that there are some image problems inside the file. Many times, we see that the color is missing. If we reduce the opacity, it comes out. The resolution of the image is very low, which is not understandable when printed. It is very sad.

Artboards Number {(15,16,17,18) Show Number (15,17,17,18)

We are still experiencing the duplicate page issue in version 29.7.1

I just came across this in build 29.6.1. Never had this before. I’m working in a large document.

29.6.1 stable/ macOS

duplicate sequence of artboard numbering?

Adobe, I believe your attempted fix may be the root cause of the new bugs introduced in 26 surrounding Artboard and keeping track of active artboard, creating new artboard, name of artboard and the default naming of artboards being another number one higher than what it should be. See the bug I reported for detail if related.

Thank you for confirming that issue is still seen, will have team look into this.

The problem still exists, Illustrator 29.6

Illustrator 29.6, the problem is still there! Artboard 201 comes after Artboard 199.

I still get the issue. Usually when creating a file with lots of artboards. Over 50+
