Experts know the importance of serial numbers.
Serial numbers are like salt. You never feel their presence but their absence makes your data tasteless.
Yes they are important.
Because with a serial number you can have a unique identity to each entry of your data.
But the sad news is, adding them manually 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 a column.
14 Ways to Insert Serial Number Column in Excel
And today, in this post, I’d like to share with you 14-Quick Methods. 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.
(1) Row Numbers as Serial Numbers
By default, in a spreadsheet, you have row numbers which act as a serial numbers for the data.
If you don’t want to use serial numbers for filtering or any other purpose then it’s better use the row headers.
Otherwise follow ahead mention methods to create a separate column of serial numbers.

(2) Use Fill Handle to Add Serial Numbers
To simply add serial numbers using fill handle you can use following 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 the cell where you want the last serial number.
- Once you get serial numbers up to you want, just release your mouse from the selection.
Quick 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.
(3) Fill Series To Automatically Add Serial Numbers
Now let’s say you want to automatically number rows 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 works like a serial number generator and you can use it even if you want up to one million.
Quick Note: This method is also not dynamic. If you want to extend the list, you need to insert serial numbers again.
(4) Use ROW Function to Drag Serial Numbers
Quick Note: If you are not starting your serial numbers from row 1, you have to add the count of rows in the formula which you have skipped. It has a benefit over other methods that it works even when you sort your data.
(5) Generate Serial Numbers by Adding One in the Previous Number
This is my favorite method and believe me, it's lighting fast.
Follow these steps
- Enter 1 in the cell from where you want to start your serial numbers.
- In next down cell, enter formula =G1+1 (G1 is the starting cell here).
- Drag this formula to down, up to the serial numbers you want.
Quick Note: It will create incremental number by adding 1 to the previous number. It is also a dynamic method, you just have to drag the formula when you want to add a new serial number.
(6) Get Serial Numbers with COUNTA Function
- Enter the following formula in the cell from where you want to start your serial numbers. (For example, your first data entry is starting from F1, enter below formula in E1).
- Drag down the formula up to the serial number your want.
Quick Note: This also a dynamic method to add serial numbers. The benefit of this method is, it will return blank if you have any blank row in your data.
(7) Add Roman Numbers as Serial Numbers
- Enter the following formula in the cell from where you want to start.
- Drag down the formula up to the serial number your want.
(8) Add Serial Numbers with a VBA Code
Sub AddSerialNumbers() Dim i As Integer On Error GoTo Last i = InputBox("Enter Value", "Enter Serial Numbers") For i = 1 To i ActiveCell.Value = i ActiveCell.Offset(1, 0).Activate Next i Last: Exit Sub End Sub
Sub AddSerialNumbers() Dim i As Integer On Error GoTo Last i = InputBox("Enter Value", "Enter Serial Numbers") For i = 1 To i ActiveCell.Value = i ActiveCell.Offset(1, 0).Activate ActiveCell.Value = i ActiveCell.Offset(1, 0).Activate Next i Last: Exit Sub End Sub

(9) Dynamic Serial Numbers for Filters
Let’s you have serial numbers in a data table and when you filter some specific data from it show you actual serials.
But, if you use a dynamic method to insert serial numbers then you can get double benefits.
First, when ever you filter data it’ll show you serial number according to the filtered item.
Second, if you want to paste that filtered data to somewhere else, you don’t have to insert them again.
For this, you can use SUBTOTAL function and the formula will be like below.
After that, drag this formula up to the last cell of the table. Now. when ever you filter data you’ll dynamic serial number.
Quick Note: If you copy data from a table where you have dynamic serial numbers and then paste those numbers to any other place. The formula which you have used for the numbers will work in the same way.
(10) Serial Numbers in a Table
The best way to automate your serial numbers is by using a table for your data. When you add a new entry, table automatically drag-down formula into the new cell.
You just need to insert a formula in first two one or two entries, after that, you’ll get it automatically.
In the below table when you enter a new entry in a new serial number automatically generates.
(11) Incremental Serial Number by Multiplying
In the comment section, Vikas asked me to add serial numbers which number should be increased by multiple of 3.
A simple solution is to enter 1 in the first cell and then multiply it with 3 and drag the formula below.
(12) Serial Numbers in a Pivot table
To add serial numbers to a pivot table you need to add an extra column in the source data.
And one more point which you need to understand that this number column will be placed after row item columns, just like below.
For this, please follow below steps:
- First of all, add a new column in your source data with 1 in each cell.
- Now, right click on that column on values section and open “Value Field Settings”.
- From here go to “Show Values As” tab and select running total in and then click OK.
Now you have a new column in your pivot table with staring from one to the maximum row.
Quick Note: This is a dynamic column and when you filter pivot numbers will change automatically.

(13) Add a Serial Dates in a Column
Now, let me show you something different. Imagine you want to enter serial wise dates in a column, you have two different methods for this.
First is, you can add starting date in a cell and then in the next cell downward refer to the above cell and add “1” into it.
Just like serial numbers, you will get a sequence of dates in the column.
Quick Note: If you want to insert dates only for one time then the second method is perfect, but if you going to expand them frequently then go with the first one.
(14). Convert Serial Numbers to Serial Dates
If you already have serial numbers in your worksheet and you want to convert them to serial dates then you can simply do that with the following formula.
Please note, with this method, you are using the serial number as a day and then you create a date.
Let’s say you you have serial numbers starting from A1, then in cell B1, add below formula.
After that, drag-down it up to the last serial number cell and you’ll get a sequence of dates.
Quick Note: Once you convert these numbers into dates then you can use method 10 to insert serial dates further.
If you have data whether small or large it is must to add serial numbers to it.
The one thing which you really need to understand that a serial number give a unique identity to each entry.
And, with all the methods you have learned above it’s no big deal to create a serial number column in the data, no matter which situation you are in.
I hope you found this useful, but now, tell me one thing.
Which method you prefer to insert serial numbers?
Please share your views with me in the comment section. I'd love to hear from you and please don’t forget to share it with your friends, I am sure they will appreciate it.
