Although there is not a command to insert sequence numbers in Excel, you can insert sequence numbers in contiguous cells with clicking and dragging mouse.

Step 1: Enter 1 in a cell, and enter 2 in a cell beside the first cell.

Step 2: Select both the cells, and drag the fill handle Description: Selected cell with fill handle across the range that you want to fill.

With dragging this fill handle, you can also fill the column of cells with sequence numbers such as these formats: “000-001,000-002,000-003…” and the sequence numbers with prefix “KTE-0001, KTE-0002, KTE-0003… ”.

Notes: 1. This way is only able to insert sequence numbers in contiguous cells.

2. If you want to create the sequence numbers with suffix or prefix and suffix, this method will not work.

I was successful in setting up 'Customize and insert unique sequence numbers with suffix and prefix' But, when I print it will only print the first number. It will not print my 50 pages with sequential numbers (201500941, 201500942, 201500943, etc) What am I doing wrong?
