Display only the last few digits of Social Security numbers
For common security measures, you may want to display only the last few digits of a Social Security number and replace the rest of the digits with zeros or other characters. You can do this by using a formula that includes the CONCATENATE, and RIGHT functions.
The following procedure uses example data to show how you can display only the last four numbers of a Social Security number. After you copy the formula to your worksheet, you can adjust it to display your own Social Security numbers in a similar manner.
- Create a blank workbook or worksheet.
- In this Help article, select the following example data without the row and column headers.
|Social Security Number
||Displays the "000-00-" text string instead of the first 5 digits of the Social Security number and combines it with the last four digits of the Social Security number (000-00-1234)
How to select example data
- Click in front of the text in cell A1, and then drag the pointer across the cells to select all the text.
- To copy the selected data, press CTRL+C.
- In the worksheet, select cell A1.
- To paste the copied data, press CTRL+V.
- To switch between viewing the result and viewing the formula that returns the result, on the Formulas tab, in the Formula Auditing group, click Show Formulas.
Keyboard shortcut You can also press CTRL+` (grave accent).
- To prevent other people from viewing the entire Social Security number, you can first hide the column that contains that number (column B in the example data), and then protect the worksheet so that unauthorized users cannot unhide the data.
For more information, see Hide or display rows and columns and Protect worksheet or workbook elements.
Important As a best practice, you may want to avoid storing complete Social Security numbers in your workbooks. Instead, store the full Social Security numbers in a location that meets stringent security standards (for example, a database program, such as Microsoft Office Access), and then use only the last four digits of the numbers in your workbooks.
