How are postcodes allocated in UK?
The allocation of postcodes depends on the amount of mail received. The unit postcodes are used to find about 30 million actual addresses or delivery points, the minimum number of delivery points for a postcode is one, the maximum is 100, and on average the postcode is allocated to 17 delivery points.
How do they assign postcodes?
It is a hierarchical system, working from left to right — the first letter or pair of letters represents the area, the following digit or digits represent the district within that area, and so on. Each postcode generally represents a street, part of a street, or a single premises.
Can a building have more than one postcode?
Note: it is possible for large buildings with many separate delivery points (for example, a tower block) to have more than one unit postcode within the building.
Does each street have a different postcode?
Codes are almost same, except for the end letter. If a small cul-de-sac then they may only have one postcode. Usually you get two postcodes, often one for even numbers and one for odd numbers. The larger the road the more postcodes it will have.

How are postcodes used in the United Kingdom?
Postcodes are a simple but convenient way to locate customers, assets, competitors – in fact, anything with an address. Enriching your address data with coordinates is a process known as geocoding and is the first step in adding location intelligence to your data assets located in the United Kingdom.
Which is the most up to date address database in the UK?
The Royal Mail PAF is widely recognised as the UK’s most up-to-date and complete address database. It contains over 30 million business and residential addresses, and 1.8 million postcodes, which are verified each day by Royal Mail’s 65,000 postmen and women.
Are there ZIP codes that match the address?
To accommodate the intense demand for data aggregated by ZIP code, the Census Bureau created ZIP Code Tabulation Areas (or ZCTAs) which are roughly what most people think of as the geography that matches a given ZIP code. But not all ZIP codes exist as ZCTAs. For example, my office address is in the ZIP code 60208, but it is in the ZCTA 60201.
Where can I find the ZIP code tabulation area?
Probably the closest approximation you could get would be to start with the Census Bureau’s ZIP code tabulation area (ZCTA) gazetteer file, which can be downloaded here. Then, using as many of the state-based “place” shape files as you need, load those into a GIS tool.
