West Valley City is trying to get their 84118, 84119, 84120, and 84128 zip codes to read "West Valley City" instead of "Salt Lake City." A survey went out to the residents of those zip codes, but instead of going to 84128, there was a typo and it was sent to 84129.
If you received one of these in the mail, and you are in the 84129 zip code, you can ignore it. It does not affect Taylorsville zip codes! The postmaster is in the process of getting an apology letter out to the 84129 zip codes about the typo.
