Where the TD districts sit
Where TD sits
It is administratively fragmented, reaching into Scottish Borders, Northumberland, Cumberland and East Lothian and 0 other authorities.
TD spans the border: 3,904 of its postcodes are in Scotland and 634 in England, about 14 per cent. That matters here in a way it does not on a plain postcode map, because water is regulated separately either side of it. In England the Environment Agency oversees drought and abstraction; in Wales it is Natural Resources Wales, and restrictions are set by whichever company supplies the address, not by which country it sits in.
Water supply across TD
All 15 TD districts are supplied by Scottish Water. That makes TD 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 TD area
TD9 is the largest district with 756 postcodes around Hawick, and TD13 the smallest with 42. The area divides into 33 postcode sectors.
Several districts share a settlement, which is a common source of confusion when a form rejects an address: TD2 and TD3 all point at Lauder, TD4 and TD6 all point at Melrose and TD10 and TD11 all point at Duns.
What borders TD
TD sits next to EH (Edinburgh) to the north west, NE (Newcastle upon Tyne) to the south east, KY (Kirkcaldy) to the north west, ML (Motherwell) to the west and DD (Dundee) to the north.
Its neighbours run in 4 different directions, so TD 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.

Frequently asked questions
How many postcode districts are in the TD area?
There are 15 TD postcode districts, running from TD1 to TD15, and they contain 4,538 live postcodes across 33 sectors.
What towns does the TD postcode area cover?
TD covers Hawick, Galashiels, Berwick-upon-Tweed, Melrose, Kelso and Duns. The area takes its name from Hawick, and each district is listed with its settlement in the table on this page.
Which water company supplies TD postcodes?
Scottish Water supplies all 15 TD 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.
Is the TD postcode area in Scotland or England?
Both. 3,904 TD postcodes are in Scotland and 634 are in England. The postcode does not decide which applies: your water company does, and water is regulated separately either side of the border.
Why do TD2 and TD3 both say Lauder?
TD2 and TD3 all serve Lauder, 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 TD postcode map?
Yes. This page offers the TD 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 TD area called Galashiels when it covers Hawick?
TD takes its letters from Galashiels, where the sorting office that served the area was based when the code was allocated. Hawick is the largest settlement in the area today, in TD9, but the area code follows the historic sorting geography rather than current population.
