Changing names
City Hall Riverview
City Hall, a place where you can change your Sim's name in The Sims 3.

Many times in The Sims series, players will end up wanting to change their Sims' names. Maybe they spelled it wrong, maybe they changed their mind, maybe they married someone with a weird name. Here is a tutorial on how to change an unwanted name.

The Sims 2 Edit

Changing First NamesEdit

  1. Download the FFS Lot Debugger and place it onto the lot.
  2. Select the Sim to be renamed.
  3. Open the console menu by pressing CTRL + SHIFT + C.
  4. Type in "boolProp testingCheatsEnabled true" without the quotes.
  5. Hold SHIFT and click on the debugger.
  6. Click on "Rename Me", and then on "Change First Name - Cancel Error".
  7. An error dialog will pop up. Click on "Cancel".
  8. The dialog used to name a baby will appear. Change the Sim's first name as you see fit.
  9. Hit "OK".

Changing Last NamesEdit

  • This way of changing names requires SimPE.
  1. Open SimPE.
  2. Click "Neighborhood Browser," and choose the neighborhood the Sim you want to rename lives in.
  3. After the files open up, click on "Sim Browser," and look for that Sim.
  4. After the Sim files open up, look at the two text boxes in the plugin view. The first one is the Sim's first name, and the second is their last name.
  5. Click on the second text box and change it to the name you prefer.
  6. Click the "Commit" button.
  7. Save.


Info information icon
Do not change first names in SimPE, and last names in-game, as certain references may not be changed correctly. First names must be changed in-game and last names must be changed in SimPE. To remember this, memorize the acronym "FILS" - First name In-game Last name SimPE.[1][2]
Info information icon
If you are not familiar with TestingCheatsEnabled or SimPE, you are advised not to try changing names.

The Sims 3Edit

City HallEdit

City hall allows Sims to change their names. The option is available between 9 AM and 6 PM. To change Sims' names, simply choose "Change Name..." option on the city hall. Sims will enter the city hall, and a text box will appear prompting the players to insert Sims' new names. It will take a while inside the city hall.

Note: To change a baby, toddler, or child's name, select the parental guardian instead of the baby, toddler, or child.

Brain Enhancing MachineEdit

This method requires University Life. A level 3 brain enhancing machine or the pro brain enhancing machine has the ability to change a Sim's personality. This will allow Sims to change their traits as well as their names. Be careful though, as personality programming can fail and randomize the Sim's traits, and may possibly burn them if they're singed.

By cheatingEdit

As of patch 1.22, players can use the testingCheatsEnabled true cheat and shift+click the target Sim to access the CAS menu by using the "Edit in CAS" option. This will send Sims to CAS, where the players are able to modify them. This method might cause some glitches, however. It might reset the Sim's age. Also, do not be tempted to make any drastic changes such as the Sim's supernatural type, the Sim's state will not be properly changed.

The Sims 4Edit

  1. Use CTRL + SHIFT + C to open the cheat console and enter 'testingcheats on'.
  2. After that, enter the cheat 'cas.fulleditmode'.
  3. Shift + click the Sim and select 'Edit in CAS'.
  4. In CAS the Sim's name can now be edited, along with anything else including traits, walk style etc. Select OK to save the renamed Sim.
