How to keep Leading Zeros in Excel

Excel is an amazing tool that can help you keep track of important data, create charts, and even perform complex calculations. However, sometimes you need to enter numbers with leading zeros in Excel, such as phone numbers or zip codes. Fortunately, there are a few easy ways to keep those leading zeros in Excel.

Method 1: Format the cells as text

The easiest way to keep leading zeros in Excel is to format the cells as text. Here's how:

  1. Select the cells that you want to format.
  2. Right-click the selected cells and choose "Format Cells".
  3. In the Format Cells dialog box, select "Text" from the Category list.
  4. Click "OK" to apply the text format to the selected cells.

Once you've formatted the cells as text, Excel will treat any numbers you enter as text, which means the leading zeros will stay in place. This is a great solution for small datasets, but can be time-consuming for larger ones.

Method 2: Use an apostrophe before the number

If you don't want to format the cells as text, you can also add an apostrophe before the number. Here's how:

  1. Type an apostrophe in the cell where you want to enter the number, such as '0123.
  2. Enter the number you want to enter after the apostrophe.

Excel will display the apostrophe in the formula bar but ignore it when calculating the value of the cell. This is a quick solution, but it means you have to remember to add the apostrophe every time you enter a number with leading zeros.

Method 3: Use the TEXT function

If you want to keep leading zeros in Excel without having to manually enter an apostrophe or format the cells as text, you can use the TEXT function. Here's how:

  1. Type the number you want to enter in a cell without leading zeros.
  2. Select a blank cell and type the following formula: =TEXT(A1, "0000")
  3. Replace A1 with the cell reference of the cell you want to format. The "0000" tells Excel to display the number with four digits, including leading zeros.
  4. Press Enter to calculate the formula.

The result will be the number with leading zeros displayed correctly. This method is great for larger datasets because you can copy and paste the formula to other cells without having to manually add an apostrophe or format each cell as text.


Keeping leading zeros in Excel may seem like a small issue, but it can make a big difference when you're working with phone numbers, zip codes, or other types of data that require leading zeros. Whether you choose to format the cells as text, use an apostrophe, or the TEXT function, all three methods will help you keep leading zeros in Excel.

So, next time you need to enter data with leading zeros, give one of these methods a try and see which one works best for you. Happy Excel-ing!
