You have to sign in to your old account and the codes should be there. Once a code is used it is locked to the account in use at that time. If you have trouble accessing your old account you will have to contact customer service. This is a public forum for user by users and accounts can not be accessed here.
Did you check your Origin account? Some TS3 packs registered automatically. Open the Origin account you used to play TS3 - click the TS3 icon - click the small i. If the packs registered they will be there for download.
If you have access to the computer the packs were installed on try:
1. Press the Windows key on your keyboard and type regedit in the search bar and press Enter.
2. Click on 'File' at the top left of the window that opens then click on 'Export'.
3. Choose a location and name for the file as this will be your backup registry file.
4. Click Save.
5. This backup is created just as a precaution.
Now to find your serial codes for each specific EP or SP installed on your computer:
1. Expand the HKEY_LOCAL_MACHINE folder.
2. Expand the SOFTWARE folder
• For 64-bit systems, expand Wow6432Node
1. Expand the Electronic Arts folder.
2. Expand the Sims folder
3. Expand the EP or SP you need the code for
4. Click on ergc and in the box to the right under 'Data' you will see the code
5. You will have to manually write the code down somewhere as you can't copy and paste.
6. You will need to expand each individual EP/SP and click on the corresponding ergc line for each serial code needed.
If the above don't work redouble yoour efforts to find the jewel cases the discs came in and hope the code is still there.
good luck
