The short answer for Charleston, WV
There is no single Charleston ZIP. Mail to the capital city of West Virginia uses a block of 253xx codes. DialWick's table is built from GeoNames' US postal-code export (CC BY 4.0), which compiles public USPS and Census fields into one row per ZIP and place name. For the exact place string Charleston in West Virginia, that export currently yields 45 rows, all in Kanawha County.
Commercial directories often advertise a shorter "standard" list and a longer "PO Box / unique" list. Both can be right for different jobs. A street address in downtown Charleston commonly uses 25301; a Cross Lanes delivery may still carry a Charleston place label on 25313; a government or corporate unique ZIP such as 25317 is not a neighborhood map. Match the five digits on the address rather than assuming one downtown code covers the whole city.
Area codes for the Charleston region are 304 and 681 in the North American Numbering Plan. ZIP boundaries and telephone NPAs are managed by different systems, so a ZIP change does not automatically move your area code.
Street-delivery ZIPs locals actually use
The rows below are the Charleston place-name ZIPs that commercial city pages most often treat as standard street delivery, plus a few unique or low-population codes that still appear in GeoNames under Charleston. Notes summarize common local aliases from public ZIP directories; they are delivery hints, not legal neighborhood boundaries.
South Charleston is a separate municipality and a separate GeoNames place name. Its primary rows are 25303 and 25309. Some directories still list those codes under a Charleston heading because mail and commuting patterns overlap; this page keeps GeoNames' place-name split so you can see which five-digit codes actually say Charleston versus South Charleston.

The long PO Box and unique tail
Beyond the street-heavy codes, GeoNames still lists many Charleston place-name rows in the 25321–25375 band that public ZIP sites classify as PO Box or unique assignments. Those codes matter for box holders and institutional mail, but they are poor choices if you are trying to guess a neighbor's street ZIP from a map.

Compare that to Augusta, Georgia on DialWick, where one busy ZIP (30907) disagrees across county columns. Charleston's GeoNames place-name set does not show a county split: every Charleston, WV row stays in Kanawha. The hard part here is place-name overlap with South Charleston and metro neighbors, not a Richmond/Columbia-style dual-county tag.
What this table is not
It is not a census tract map of the City of Charleston. Municipal limits, school districts, and ZIP polygons are drawn by different agencies for different jobs. A house can sit inside city limits while its mail place name points elsewhere, and the reverse also happens along metro edges.
It is also not a list of every ZIP in Kanawha County. Dunbar (25064), Elkview (25071), Nitro (25143), Saint Albans (25177), and many coal-camp or river-town codes sit in the same county without carrying Charleston as their primary place string. For those, look up the place name on the envelope, not the county seat.
USPS does not publish a free bulk ZIP-to-city-to-county file for reuse. GeoNames' export is the public compilation DialWick uses across city pages such as Augusta GA ZIP codes and Boynton Beach ZIP codes. When a commercial site and GeoNames disagree on a single row, this page keeps the GeoNames place-name field and flags the conflict instead of silently picking a favorite.
How to pick the right Charleston ZIP
If you already have a street address, use USPS ZIP Lookup or the five digits printed on recent mail for that address. Do not copy a neighbor's code across a major road; Charleston's 253xx block is dense enough that adjacent blocks can differ.
If you only know a neighborhood nickname (South Hills, Kanawha City, Cross Lanes, Sissonville), treat the alias column above as a starting hint, then confirm against an address. Nicknames travel farther than ZIP polygons.
If you are shipping to a PO Box, use the box ZIP the holder gives you. Many 2532x–2536x Charleston place-name codes exist for boxes and will bounce street carriers if you invent a house number.
