Creating Unique ID number

[ExcelDud91]

Hi All,

I'm so close to having a formula work for me but fallen just short at the end:

I have A Unique ID column which i want to auto populate based on the columns [first 2 letters of category]-[3 numbers in event]-[auto list number starting from 001 and going up]

With the Code I have now i can get
DM-001
DM-001
DM-001

Which is correct however I want to add the -001 -002 and so on so it reads
DM-001-001
DM-001-002
DM-001-003

The formula im using is:

To best describe or illustrate your problem you would be better off attaching a dummy workbook. The workbook should contain the same structure and some dummy data of the same type as the type you have in your real workbook - so, if a cell contains numbers & letters in this format abc-123 then that should be reflected in the dummy workbook.

To attach a file to your post,
click advanced (next to quick post),
scroll down until you see "manage file",
click that and select "add files" (top right corner).
click "select files" find your file, click "open" click "upload" click 'done" bottom right. click "submit reply"

Once the upload is completed the file name will appear below the input boxes in this window.
You can then close the window to return to the new post screen.

Hi ExcelDud,

Something like this formula using a helper column might be what you need.

Without the helper Column this formula should work:

Hi,

I worry about all solutions above. The idea of a Unique ID is that they don't change even after a sort from another column. Both formulas might change IDs after sorting. If you get an answer you like with a formula, I'd past the Values Only over the top of the formula so they wouldn't change when sorting the table.
