Coverage
Coverage is a claim, so it is worth being specific about.
Almost every recovery agency’s website says it covers more ground than it works. Eight named counties and 255 ZIP codes can be checked. A shaded region on a map cannot.
Check a ZIP code.
The lookup runs against the 255 ZIP codes Shield published on its own coverage page, covering the same eight counties Shield works today. A ZIP that is not on it is not an automatic refusal — ZIP boundaries and county lines do not agree everywhere, so an address near the edge gets confirmed by operations rather than guessed at by a website.

If the ZIP is not on the list, ask anyway.
The list is conservative by design. Operations can give a straight answer on a specific address faster than a coverage map can imply a wrong one.
