Where the ZE districts sit
Where ZE sits
The whole area sits inside Shetland Islands, which is unusual at this size.
Every ZE postcode is in Scotland. Water there is regulated by the Scottish Environment Protection Agency, and Temporary Use Bans under the Water Industry Act 1991 do not apply in Scotland at all.
Water supply across ZE
All 3 ZE districts are supplied by Scottish Water. That makes ZE simple in a way many areas are not: one company, one set of rules, one status to check.
We are re-checking Scottish Water's status. It was last confirmed on 17 August 2026 as no restrictions, and until it is confirmed again this page does not assert a current position for it.
The shape of the ZE area
ZE1 is the largest district with 327 postcodes around Lerwick, and ZE3 the smallest with 12. The area divides into 4 postcode sectors.
ZE1 alone holds about 50 per cent of every postcode in ZE,.
District by district: ZE1 serves Lerwick, ZE2 serves Lerwick and ZE3 serves North Town.
Several districts share a settlement, which is a common source of confusion when a form rejects an address: ZE1 and ZE2 all point at Lerwick.
What borders ZE
ZE sits next to KW (Wick) to the south west, AB (Aberdeen) to the south, IV (Inverness) to the south west, DD (Dundee) to the south and PH (Perth) to the south west.

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.

Frequently asked questions

What towns does the ZE postcode area cover?
ZE covers Lerwick and North Town. The area takes its name from Lerwick, and each district is listed with its settlement in the table on this page.
Which water company supplies ZE postcodes?
Scottish Water supplies all 3 ZE 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 ZE1 and ZE2 both say Lerwick?
ZE1 and ZE2 all serve Lerwick, 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.
