Many homes and businesses were caught unaware of new zip codes in Lee County Florida.  33912, located in South Fort Myers, has approximately 13,500 residences that split off into two new zip codes, 33966 and 33967 last year.  The postal service will no longer accept the old 33912 on those residences, and mail may be returned as undeliverable.

Lehigh Acres received three new zip codes, 33973, 33974 or 33976.
