Does 401K Expire? 
That is a great question ! If what you are asking is something along the lines of `` I had this job once , with a 401k , and I left the job , does the 401k still exist ? '' , the answer is yes , it does ! It may be hard to find if the company is n't around anymore , but it does still exist in some financial institution that is overseeing it . Start with the company HR department if they still exist , or hunt up the bank that used to do your paychecks , you might get lucky . If that does n't work , try your Secretary of state , it should be on file who they used . Thanks for asking , and happy hunting !
