Water supply across WS
All 15 WS districts are supplied by South Staffs Water. That makes WS simple in a way many areas are not: one company, one set of rules, one status to check.
We are re-checking South Staffs Water's status. It was last confirmed on 18 August 2026 as voluntary appeal, and until it is confirmed again this page does not assert a current position for it.
The shape of the WS area
WS15 is the largest district with 1,075 postcodes around Rugeley, and WS8 the smallest with 323. The area divides into 64 postcode sectors.
Several districts share a settlement, which is a common source of confusion when a form rejects an address: WS1, WS2, WS4 and WS5 all point at Walsall, WS6, WS11 and WS12 all point at Cannock and WS13 and WS14 all point at Lichfield.
What borders WS
WS sits next to WV (Wolverhampton) to the south west, B (Birmingham) to the south, ST (Stoke-on-Trent) to the north, DY (Dudley) to the south west and TF (Telford) to the west.
Its neighbours run in 4 different directions, so WS is landlocked by other postcode areas on most sides.

Hardness is published per census area, not per postcode, so these figures characterise a district rather than measuring one address. They are a scale and taste matter, not a safety one. Hardness data version wessex-water@2022-2025+yorkshire-water@2026.

No signup, no email wall. GeoJSON carries the district points, the supplier and the live status, so it can be dropped straight into a map.
District positions are averaged postcode centroids from OS Code-Point Open. They show roughly where a district sits, not where its boundary runs, and are not legal boundaries.
Frequently asked questions
How many postcode districts are in the WS area?
There are 15 WS postcode districts, running from WS1 to WS15, and they contain 10,307 live postcodes across 64 sectors.
What towns does the WS postcode area cover?
WS covers Cannock, Walsall, Lichfield, Rugeley, Bloxwich and Darlaston. The area takes its name from Cannock, and each district is listed with its settlement in the table on this page.
Which water company supplies WS postcodes?
South Staffs Water supplies all 15 WS districts. Supply boundaries follow the pipe network rather than postcode geography, so confirm against your water bill if you are near the edge of the area.
Why do WS1 and WS2 both say Walsall?
WS1, WS2, WS4 and WS5 all serve Walsall, covering different parts of it. A single town routinely needs more than one postcode district once it passes a few thousand delivery points, so this is normal rather than an error in an address.
Can I download a free WS postcode map?
Yes. This page offers the WS districts as GeoJSON, CSV and SVG, free and with no signup or email address required. The GeoJSON carries each district's position, its water company and its current restriction status, so it can be dropped straight into a mapping tool.
Why is the WS area called Walsall when it covers Rugeley?
WS takes its letters from Walsall, where the sorting office that served the area was based when the code was allocated. Rugeley is the largest settlement in the area today, in WS15, but the area code follows the historic sorting geography rather than current population.
Which councils cover the WS postcode area?
WS reaches into Staffordshire, Walsall and Sandwell. A postcode area is not a council area: they were drawn for different purposes and a single district can sit across a council boundary, so your postcode does not tell you which authority you pay.
