Serial numbers are like salt. Their presence is not felt, but absence makes your data tasteless. Yes, they are important.

With a serial number, you will have a unique identity to each data entry. But the sad news is, adding them is a pain. It’s really hard to add a number in every row one after another.

The good news is, there are some ways which we can use to automatically add serial numbers in Excel.

And today, in this post, I’d like to share with you 6 quick methods which will tell you how to insert serial numbers in Excel without wasting much time.

You can use any of these methods which you think is perfect for you. These methods can generate numbers up to a specific number or can add a running column of numbers.

So without further ado, here are the methods.

Seven Methods To Add Serial Numbers in Excel

Fill handle is one the easiest ways to get serial numbers. Here are the steps.

- Enter 1 in a cell and 2 in the next cell downward.
- Select both the cells and drag down with fill handle (a small dark box at right bottom of your selection) up to up to the cell where you want serial number.
- Once you get serial numbers up to you want, just release your mouse from the selection.

Important Note

- This is not a dynamic method, you have to insert serial numbers again when you update your data.
- Inserting 1 and 2 in the cells is a must. If you try to drag by using only 1, it will start to repeat 1 in all cells.

Now, let’s say you want to add numbering up to 10000 or 100000. And, you want to do this in a one go.

Maybe it’s a pain with fill handle but, you can use fill series to generate a column with serial numbers in a one go.

Here are the steps.

- Select the cell from where you want to start your serial numbers and insert “1” in it.
- Now, go to home tab -> editing -> fill -> series.
- In the series window, do the following.
- Series In = Column.
- Step Value = 1
- Stop Value = 10000 or whatever you want up to.
- Click OK.

The best part of this method is it will automatically add serial numbers even if you want up to one million.

Important Note:

- This method is not dynamic. If you want to extend serial numbers you have to insert them again.

This is my favorite method and believe me, it's lighting fast.

Follow these steps.
