You can make changes to your AdWords account, such as viewing it in a different language or viewing numbers in a different format. Account time zones may be changed once over the life of an account. If you need to correct your time zone selection, please contact us to request a change. One thing that can't be changed in your AdWords account, however, is the currency.
You can also change settings -- such as the language, country, and zip code -- for all your Google products. No matter what changes you make, however, these settings don't change how people see your ads.
To change the language or number format -- such as how dates or currencies appear -- in your AdWords account:
  1. Sign in to your AdWords account at https://adwords.google.com.
  2. Click the gear icon  and select Account settings .
    Preferences Tab
  3. Select Preferences.
  4. Next to "Language and number preferences," click Edit.
    Language and number preferences
  5. Select the language in which you'd like to view your AdWords account and the format you'd like for your account's times, dates, and numbers.
  6. Click Save changes.
