Where DD sits
It is administratively fragmented, reaching into Angus, Dundee City, Perth and Kinross and Aberdeenshire and 1 other authority.
Every DD 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 DD
All 11 DD districts are supplied by Scottish Water. That makes DD 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.

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
How many postcode districts are in the DD area?
There are 11 DD postcode districts, running from DD1 to DD11, and they contain 9,123 live postcodes across 51 sectors.
What towns does the DD postcode area cover?
DD covers Dundee, Forfar, Broughty Ferry, Arbroath, Montrose and Brechin. The area takes its name from Dundee, and each district is listed with its settlement in the table on this page.
Which water company supplies DD postcodes?
Scottish Water supplies all 11 DD 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 DD1 and DD2 both say Dundee?
DD1, DD2, DD3 and DD4 all serve Dundee, 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 DD postcode map?
Yes. This page offers the DD 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.
Which councils cover the DD postcode area?
DD reaches into Angus, Dundee City, Perth and Kinross, Aberdeenshire and Fife. 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.
How many postcode sectors are in DD?
DD contains 51 postcode sectors across its 11 districts. A sector is the district plus the first digit of the second half of the postcode, and it is the level a delivery round is actually planned around.
