Where FK sits
It is administratively fragmented, reaching into Falkirk, Stirling, Clackmannanshire and Fife and 2 other authorities.
Every FK 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 FK
All 21 FK districts are supplied by Scottish Water. That makes FK 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 FK area
The districts are wildly uneven: FK2 holds 1,235 postcodes around Falkirk and FK18 holds 8, a ratio of about 154 to one. They divide into 49 sectors.
Several districts share a settlement, which is a common source of confusion when a form rejects an address: FK1, FK2 and FK5 all point at Falkirk, FK17, FK18 and FK19 all point at Callander and FK4 and FK6 all point at Denny.
What borders FK
FK sits next to G (Glasgow) to the south west, ML (Motherwell) to the south, KY (Kirkcaldy) to the east, PH (Perth) to the north west and EH (Edinburgh) to the south east.
Its neighbours run in 5 different directions, so FK 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.
Download the FK data
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 FK area?
There are 21 FK postcode districts, running from FK1 to FK21, and they contain 7,789 live postcodes across 49 sectors.
What towns does the FK postcode area cover?
FK covers Falkirk, Stirling, Alloa, Denny, Grangemouth and Bridge of Allan. The area takes its name from Falkirk, and each district is listed with its settlement in the table on this page.
Which water company supplies FK postcodes?
Scottish Water supplies all 21 FK 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 FK1 and FK2 both say Falkirk?
FK1, FK2 and FK5 all serve Falkirk, 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 FK postcode map?
Yes. This page offers the FK 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 FK postcode area?
FK reaches into Falkirk, Stirling, Clackmannanshire, Fife, West Lothian and Perth and Kinross. 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 FK?
FK contains 49 postcode sectors across its 21 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.
