The country's largest carriers have suspended service in some Florida ZIP codes impacted by Hurricane Ian.

The trio of UPS, FedEx and the U.S. Postal Service have identified on their respective websites a list of area codes where service will be suspended temporarily.

As of noon Thursday, UPS' service alerts page listed nearly 1,000 ZIP codes that have been affected, while FedEx on Wednesday shared a list of 383 Florida cities — including Tampa, Orlando and Miami — in which its Ground segment will not run for the time being. 

The Postal Service, meanwhile, issued a notice that all retail and delivery operations will be suspended in the 328-, 329-, 342- and 347- ZIP code areas, which designate Orange, Brevard, Indian River, Manatee and Sarasota counties, among others.
