Keep 0 Before a Phone Number in Excel (6 Methods)

In some cases, a number starts with zero (0). Such as phone numbers, credit card numbers, product codes, postal codes, personal identification numbers, etc. When you insert any of these numbers in an Excel worksheet having a leading zero, Excel automatically removes the zeros (0) from the front side. The way you can skip this problem is to apply the Text format to the numbers. In this article, you will get to know 6 methods to put 0 before a phone number in Excel.

Why Excel Removes Leading Zeros?

When you insert numbers in an Excel worksheet having leading zeros, Excel automatically removes all of them. For example, if you insert 007 in a cell in Excel, you will see only 7 is there. The two zeros before 7 are no more.

This happens because any number of zeros, before real numbers, is meaningless. So, when you insert numbers with leading zeros in an Excel worksheet, Excel automatically removes them from a cell. It only keeps the digits that make sense.


Retain Leading Zeros in Excel

There are two possible ways that you can follow to retain the leading zeros in Excel.

  • Format the numbers into Text. This will prevent Excel from removing the leading zeros. Put an apostrophe (‘) in front of the numbers. This will change the format into Text.
  • You can set the cell format in such a way that it always displays a certain number of digits. For example, you have set a cell to display 7 digits in total. Now you are inserting only 5 digits. Excel will automatically insert two leading zeros to make it 7 digits in total. This is how you can retain the leading zeros too.

6 Methods to Keep 0 (Zero) Before a Phone Number in Excel

1. Apply Text Format to Retain 0 Before a Phone Number in Excel

When you insert a number with leading zeros in a cell, Excel automatically removes that zero. So you might face problems while inserting phone numbers in your Excel worksheet.

To keep that leading zero of phone numbers, follow the process below:

  • Highlight all the cells where you want to keep the numbers with a leading zero.
  • Go to the HOME ribbon.
  • From the Number group, select the Text format.

So, all the cells in your selected area are now under the Text format.

2. Use Apostrophe to Keep the Leading Zeros of a Phone Number in Excel

Using an apostrophe before inserting numbers in an Excel cell is the quickest way to apply the Text format. This is how you can keep 0 before any kind of numbers such as personal identification numbers, postal codes, credit card numbers, bank account numbers, area codes, product numbers, etc.

All you need to do is,

  • Insert an apostrophe (‘) in an Excel cell first.
  • Then type the numbers started with a zero (0).
  • Finally hit the ENTER button.

Add an extra apostrophe before the numbers will convert the cell format into Text. Thus Excel won’t remove that zero in this case.

  • Press CTRL + 1 to open the Format Cells dialog box.
  • Or you can right-click on the selection area. Then from the pop-up list, select Format Cells.

4. Apply Custom Format to Keep the Preceding Zero in a Phone Number in Excel

To apply the Custom format upon the cells,

  • Highlight the cells to insert numbers with preceding zeros.
  • Press CTRL +1 to open the Format Cells dialog box.
  • Select the Number ribbon.
  • Click on Custom under the Category list.
  • Then Insert
    “0”##########
    into the Type box and hit OK.

Here the zero (0) within the double quotation mark will ensure that 0 stays in a cell in Excel. Then the following hashes (#) define the number of digits that you want to allow after the leading zero.

This makes 11 digits in total. Now if you insert 11 digits with a zero at the front, Excel will keep the zero untouched.

  • After that hit the ENTER button from your keyboard.
