PH postcode district map, Perth
Supplier statuses last checked .
The PH postcode area covers 43 districts and 6,235 live postcodes, from PH1 to PH50. It is centred on Perth and also covers Blairgowrie and Rattray, An Gearasdan, Crieff, Pitlochry and Alyth.
Its districts are sparse, averaging 145 postcodes each.
Where the PH districts sit
15 districts are plotted without a label where labels would overlap; every one is in the table below.
Where PH sits
It falls across Perth and Kinross, Highland and Angus.
Every PH 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 PH
All 43 PH districts are supplied by Scottish Water, which is notable at this size: an area with this many districts usually crosses at least one supply boundary, and this one does not.
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 PH area
The districts are wildly uneven: PH2 holds 1,271 postcodes around Perth and PH44 holds 1, a ratio of about 1271 to one. They divide into 62 sectors.
PH2 alone holds about 20 per cent of every postcode in PH,.
The numbering is not continuous. PH runs up to 50 but has only 43 districts, so 7 numbers are unused:.
Several districts share a settlement, which is a common source of confusion when a form rejects an address: PH31, PH33, PH34, PH37, PH49 and PH50 all point at An Gearasdan, PH5, PH6 and PH7 all point at Crieff and PH9, PH16 and PH18 all point at Pitlochry.
What borders PH
PH sits next to FK (Falkirk) to the south east, PA (Paisley) to the south west, IV (Inverness) to the north, G (Glasgow) to the south and KY (Kirkcaldy) to the south east.
Its neighbours run in 4 different directions, so PH 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 PH 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 PH area?
There are 43 PH postcode districts, running from PH1 to PH50, and they contain 6,235 live postcodes across 62 sectors.
What towns does the PH postcode area cover?
PH covers Perth, Blairgowrie and Rattray, An Gearasdan, Crieff, Pitlochry and Alyth. The area takes its name from Perth, and each district is listed with its settlement in the table on this page.
Which water company supplies PH postcodes?
Scottish Water supplies all 43 PH 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 PH31 and PH33 both say An Gearasdan?
PH31, PH33, PH34, PH37, PH49 and PH50 all serve An Gearasdan, 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 PH postcode map?
Yes. This page offers the PH 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 PH postcode area?
PH reaches into Perth and Kinross, Highland and Angus. 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.
Why is there no PH29 postcode district?
PH29 is not in use. Postcode districts are allocated as sorting requirements change rather than numbered straight through, and a code that is retired or never brought into service is not reissued, so gaps in the sequence are normal.
