# How to Enter 16 Digit Number in Excel: A Step-by-Step Guide

Entering a 16 digit number in Excel can be tricky because Excel treats long numbers as scientific notation by default, making it hard to work with precise values. By following a few simple steps, you can easily enter and maintain the integrity of 16-digit numbers in Excel.

## How to Enter 16 Digit Numbers in Excel

In this section, you’ll learn how to properly input a 16-digit number into Excel, ensuring it doesn’t get converted into scientific notation. Just follow these steps, and you’ll have your long numbers displayed correctly.

### Step 1: Open Excel

The first step is to open Microsoft Excel.

Open Excel on your computer. You can either open a new workbook or an existing one, depending on where you want to enter your 16-digit number.

### Step 2: Select the Cell

Next, select the cell where you want to enter the 16-digit number.

Click on the specific cell in which you want to type your 16-digit number. This could be any cell in the worksheet.

### Step 3: Format the Cell as Text

Format the selected cell as text to prevent Excel from converting the number to scientific notation.

Right-click the selected cell, choose "Format Cells" from the context menu, and select "Text" under the Number tab. This ensures that whatever you type in the cell will be treated as text rather than a number.

### Step 4: Enter the 16 Digit Number

Now, you can type the 16-digit number into the formatted cell.

After formatting the cell as text, simply type your 16-digit number and press Enter. Because the cell is set to text format, Excel will not change the number to scientific notation.

### Step 5: Verify the Number

Finally, verify that the number appears exactly as you entered it.

Double-check the cell to make sure the 16-digit number is displayed correctly without any changes or errors.

After completing these steps, your 16-digit number should appear exactly as you entered it, without any unwanted changes or formatting.

## Tips for Entering 16 Digit Numbers in Excel

Here are some additional tips to help you maintain accuracy when working with long numbers in Excel:

• Double-check formatting: Always ensure the cell is formatted as text before entering long numbers.
• Use an apostrophe: You can also enter a 16-digit number by placing an apostrophe (‘) before the number, which tells Excel to treat it as text.
• Avoid copy-pasting: When pasting long numbers, ensure the destination cells are pre-formatted as text.
• Cell formatting shortcuts: Use keyboard shortcuts like Ctrl+1 to quickly open the Format Cells dialog.
• Formula bar review: Check the formula bar to verify that the full number is displayed correctly.

### Why does Excel change my 16-digit number to scientific notation?

Excel automatically converts long numbers to scientific notation because it is designed to handle numerical values up to 15 digits accurately.

### Can I prevent Excel from changing long numbers?

Yes, by formatting the cell as text before entering the number, Excel will treat it as text and not change it to scientific notation.

### What if I’ve already entered the number?

If you’ve already entered the number and it changed to scientific notation, you can reformat the cell as text and re-enter the number.

### Is there another way to enter long numbers without formatting the cell?

Yes, you can use an apostrophe (‘) before typing the number. This method also forces Excel to treat the number as text.

### Can I apply text formatting to multiple cells at once?

Absolutely. Select all the cells you want to format, right-click, choose "Format Cells," and select "Text."
