You should call the company that you worked at and tell them to send you another one with the correct address. They will contact the OPA office and forward a W-2 Correction Request along with other documentations. Expect the process to be 10-15 days.

Or the quickest way is to go to this link and correct it:

 By law, all companies have to mail w-2's by January 31st. You can call the reporting company and ask for a duplicate, sent to the correct address.

 2008 W-2 Forms have not been issued. If you are asking about one issued for 2007, you would need to contact your employer for an amended or duplicate with the correct address.

 You should not have a 2008 W2 yet. This year is not over. If you just quit a job they will send it to you by Jan. 31 of 2009. All you should have right now would be 2007 W2. If you have not yet received your 2007 W2 you need to call your previous job and ask for either your boss (if this is a small company) or Human Resources/Payroll Dept. If a larger company.
You can not get 2008 because this year has not yet ended.
