1. Formatting Cells to Keep Leading Zeros

To keep leading zeros in Excel, formatting cells provides the simplest option to follow. You can customize the number or convert it into text format with a few clicks only.

1.1 Customizing Number Format

Here’s the list of 8 states with their Zip Codes. Now we want to keep the same format for all zip codes by adding 0’s before them where necessary.

1.2 Using Built-In Special Formats

We can do the same thing by choosing the Special option in the Format Cells dialogue box. Then select the Zip Code option, press OK & you’re done.

  • For this, you can go for other common formats here available like- Phone Number, Serial Security Number, etc. These are all assigned to the default location USA. You can also change the location by selecting another area or country from the Locale drop-down & then you’ll be able to find similar options as number formats for the selected region.

Using Built-in Special Formats to Apply ZIP Code format

  • As a result, you will see that there will be leading zeros in front of the numbers.

1.3 Applying Text Format

By using Text format, we can also keep the leading zeros as required.

📌 Steps:

  • Select the cells where you want to input zip codes.
  • From the Number group of commands, Select the format as Text from the drop-down.
  • Now start typing all the zip codes in the cells & you’ll see no leading zero is removed.

  • As this method takes some time to execute for all data manually, so this method is effective when you need to input data rather than formatting a range of stored data.


2. Using TEXT Function to Add Preceding Zeros

The TEXT function is another fruitful way you can use to format the numbers by adding leading zeros.

📌 Steps:

  • Here. in Cell D5 insert the following formula:


🔎 Formula Breakdown:

  • The TEXT function converts a number to text in a specific value format.
  • Here inside the parenthesis, C5 is the cell value that is formatted in “00000” text format.
  • Press Enter & you’ll see the desired result.
  • Now to do the same for all cells, use the Fill Handle option from Cell D5 to fill down to the last Cell D12 & you’ll find all the zip codes with a similar format.

3. Adding Apostrophes Before Numbers

We can also use an apostrophe before a number & then add zeros as required. This will convert the cell into a text format.

  • For this, you have to add apostrophes manually before each number and then add the leading zeros. Thus you can simply convert the numbers to text format.

  • As this method represents the text format, so you’ll find the error message again containing “Number Stored as Text. So you’ll have to select Ignore Error for all the cells having error messages.

4. Combining RIGHT Function with Ampersand Operator

Now, this is another perfect method that returns the result using the RIGHT function and Ampersand operator (&). You can also use the CONCATENATE function instead of & operator.

📌 Steps:

  • In Cell D5 insert the following formula:


  • Press Enter button.
  • Use Fill Handle to fill down all other cells containing zip codes.

Combining RIGHT Function with Ampersand Operator to Keep Leading Zeros

🔎 Formula Breakdown:

  • Here, the RIGHT function returns the specified number of characters from the end of a text string.
  • We’re concatenating 00000 before each number by using Ampersand(&) between the 00000 & the cells.
  • Now, the RIGHT function is allowing only the last 5 characters of each resultant data to be input into the cells.

5. Using BASE Function

BASE function is used to convert a number to different number systems (Binary, Decimal, Hexadecimal or Octal). You can also define how many characters you want to see through this function.

📌 Steps:

  • In Cell D5 insert the following formula:


  • Press Enter.
  • Use Fill Handle to autofill all other cells as required.

🔎 Formula Breakdown:

Inside the arguments of the BASE function,

  • C5 is chosen as the Cell value for C5.
  • 10 is the radix or number system for decimal values.
  • And 5 is the number of characters we want to see as a result.

📌 Steps:

  • In Cell D5, type-


  • Press Enter & you’ll be displayed the formatted values right away.

Using REPT and LEN function

🔎 Formula Breakdown:

  • REPT function has come from Repeat word & this function repeats text a given number of times.
  • LEN function returns the number of characters of a text string.
  • Now, inside the arguments, 0 has been added first as this is the text value we want to repeat as leading zeros before numbers as required.
  • 5-LEN(C5) denotes the number of leading zeros(0’s) that need to be added or repeated.
  • Lastly, C5 Cell is added to the whole function by using Ampersand(&) as this cell value has to be placed after leading zeros.

Hello, Welcome to my profile. I'm a Technical Content Creator as well as a Naval Architect & Marine Engineer. I have preferences to do analytical reasoning & writing articles on various statistical data. Here, you'll find my published articles on Microsoft Excel & other topics related to my interests!

  1. Unfortunately none of these methods works for me.
    I have a list of article numbers. They come in lots of different ways (different lengths, only numbers, only letters, numbers+letters, some with an a – or a . or a / somewhere,… So there is no predefined special format applicable for all references.
    Some are preceded by a 0 (or more 0s).
    I need to use vertical lookup function to link tables.
    When I copy a cell or the column, the leading 0 is still showed in the copied cell(s).
    But with every action I do in excel, the leading 0 disappears. Even when I just make the cell format as “text”, the 0 still disappears. So I don’t want to add a 0, I just want to keep those that are there.
    The list is also to long to add a ‘ in front of each number.
    Note: When I click on a cell with a leading 0 visible in the cell, the formula bar doesn’t show that leading 0.
    How to resolve?

    • Hi Amelie,
      Thanks for your comment. As your dataset doesn’t follow any regular pattern, so I think we need an additional column to solve this issue. The procedure is:
      1) First, insert a new column just right after your data column.
      2) Then, at the first cell of that column, write down ‘[Value].
      Here, the [Value] represents the data of the previous column.
      3) Now, double-click on the Fill Handle icon.
      4) The same result will be pasted on every cell. Click on the Auto Fill Options > Flash Fill option.
      5) The apostrophe will add to every cell value, and it will prevent the disappearance of zero (0) from your dataset.
      I hope you will be able to restore your cell values accurately. Please inform us if you are still facing any trouble.
