Postcode Boundaries, as estimated by ABS

Unlike in the United States, postal codes do not allow for a geographical division of the country. The same postal code can be used for addresses in several municipalities, and a municipality may have addresses with different postal codes. For more information, see article on Wikipedia.

Very exceptionally, it may be useful to have contours, especially when a procedure is built exclusively on the entry of a postal code.

This dataset contains a polygon by postal code significantly used in the National Address Base. Each polygon is a simple convex envelope around addresses using the same postal code. The polygons overlap quite widely.

Two attributes are proposed: ‘Codepostal’ and ‘nbNumeros’ (number of addresses attached in the BAN).

Comprehensive, weekly-updated polygon datasets covering postal and administrative boundaries for 247 countries, featuring up to 6 hierarchical levels, edge-matched polygons, and enriched with attributes like population, multilingual support, UNLOCODEs, IATA codes, and time zones.

Postal Areas (POA)

Postal Areas (POAs) are designed to approximate postcode boundaries, as closely as possible. There is not a one-for-one correspondence between Australia Post postcodes and POAs, but these are a good starting point for comparison of Census data with other data collected using postcodes.

Census Postal Areas exclude non-mappable Australia Post postcodes such as:

• post office box postcodes
• some delivery route postcodes, which are also covered by other postcodes (a situation which often occurs in rural areas)
• some postcodes which, because of the application of the 'best fit' principle, do not get a Mesh Block allocated to them.

Dataset contains polygons corresponding to the top level (Postcode Area) of the GB Postcode Hierarchy. Thiessen polygons were generated from all records in OS OpenData Code-Point Open. Resulting coverage was dissolved up to postcode area level and then clipped to GB extent of the realm using OS OpenData Boundary-Line. Names of postcode areas were added from Wikipedia. GIS vector data. This dataset was first accessioned in the EDINA ShareGeo Open repository on 2010-07-22 and migrated to Edinburgh DataShare on 2017-02-21.

1. Zip code boundaries change, in ways small and large - these are not a stable analysis unit. Data you received keyed to zip codes may have used an earlier and very different boundary for your zip codes of interest.
2. Historically, the United States Postal Service has not published zip code boundaries, and instead, boundary datasets are compiled by third party vendors from address data. That means that the boundary data are not authoritative, and any data you have keyed to zip codes may use a different, vendor-specific method for generating boundaries from the data here.
3. Zip codes are designed to optimize mail delivery, not social, environmental, or demographic characteristics. Analysis using zip codes is subject to create issues with the Modifiable Areal Unit Problem that will bias any results because your units of analysis aren't designed for the data being studied.

The PTV Postcode Boundaries Germany data set is based on information from a wide range of sources and, in addition to the postcode boundaries (5-digit postcodes), also contains the postcode regions (2-digit postcodes) and postcode zones (1-digit postcodes) as well as the postcode districts (PLB, 4-digit).

This is the ONS Postcode Directory (ONSPD) for the United Kingdom as at February 2023 in Comma Separated Variable (CSV) and ASCII text (TXT) formats. This file contains the multi CSVs so that postcode areas can be opened in MS Excel. To download the zip file click the Download button. The ONSPD relates both current and terminated postcodes in the United Kingdom to a range of current statutory administrative, electoral, health and other area geographies. It also links postcodes to pre-2002 health areas, 1991 Census enumeration districts for England and Wales, 2001 Census Output Areas (OA) and Super Output Areas (SOA) for England and Wales, 2001 Census OAs and SOAs for Northern Ireland and 2001 Census OAs and Data Zones (DZ) for Scotland. It now contains 2021 Census OAs and SOAs for England and Wales. It helps support the production of area based statistics from postcoded data. The ONSPD is produced by ONS Geography, who provide geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations. The ONSPD is issued quarterly. (File size - 234 MB)NOTE: The 2022 ONSPDs included an incorrect update of the ITL field with two LA changes in Northamptonshire. This error has been corrected from the February 2023 ONSPD.NOTE: There was an issue with the originally published file where some change orders yet to be included in OS Boundary-LineÔ (including The Cumbria (Structural Changes) Order 2022, The North Yorkshire (Structural Changes) Order 2022 and The Somerset (Structural Changes) Order 2022) were mistakenly implemented for terminated postcodes. Version 2 corrects this, so that ward codes E05014171–E05014393 are not yet included. Please note that this product contains Royal Mail, Gridlink, LPS (Northern Ireland), Ordnance Survey and ONS Intellectual Property Rights.

This layer is part of Vicmap Lite and contains polygon features delineating postcode areas. Vicmap Lite datasets are suited for use between scales of 1: 250,000 and 1 : 5 million. The polygons were sourced from Vicmap Admin. The level of attribute information and the number of vertices has been simplified to suit the 1: 250,000 - 1 : 5 million scale range. The concept of a Scale Use Code has been introduced to help control the level of detail displayed.

The 2019 cartographic boundary shapefiles are simplified representations of selected geographic areas from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). These boundary files are specifically designed for small-scale thematic mapping. When possible, generalization is performed with the intent to maintain the hierarchical relationships among geographies and to maintain the alignment of geographies within a file set for a given year. Geographic areas may not align with the same areas from another year. Some geographies are available as nation-based files while others are available only as state-based files. ZIP Code Tabulation Areas (ZCTAs) are approximate area representations of U.S. Postal Service (USPS) ZIP Code service areas that the Census Bureau creates to present statistical data for each decennial census. The Census Bureau delineates ZCTA boundaries for the United States, Puerto Rico, American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, and the U.S. Virgin Islands once each decade following the decennial census. Data users should not use ZCTAs to identify the official USPS ZIP Code for mail delivery. The USPS makes periodic changes to ZIP Codes to support more efficient mail delivery. The Census Bureau uses tabulation blocks as the basis for defining each ZCTA. Tabulation blocks are assigned to a ZCTA based on the most frequently occurring ZIP Code for the addresses contained within that block. The most frequently occurring ZIP Code also becomes the five-digit numeric code of the ZCTA. These codes may contain leading zeros. Blocks that do not contain addresses but are surrounded by a single ZCTA (enclaves) are assigned to the surrounding ZCTA. Because the Census Bureau only uses the most frequently occurring ZIP Code to assign blocks, a ZCTA may not exist for every USPS ZIP Code. Some ZIP Codes may not have a matching ZCTA because too few addresses were associated with the specific ZIP Code or the ZIP Code was not the most frequently occurring ZIP Code within any of the blocks where it exists. The generalized ZCTA boundaries in this file are based on those delineated following the 2010 Census.
