How Postcodes Work The Postcode is a group of between 5 and 7 letters and numbers that identify a group of houses or addresses. Area Postcodes - Level 1 The country is divided Areas denoted by the first two letters of the Outward half of the Postcode. Example: SW. Level 1: Area. Example: SW6. Level 2: District. Sector Postcodes - Level 3 Each District is further segmented down into Sectors 9, in total which are denoted by the first number of the second part of the Postcode.
Example: SW6 3. Level 3: Sector. Unit Postcodes - Level 4: Not Illustrated The fourth and final level of the Postcode pinpoints a group of houses or addresses. Example: SW6 3AZ. Since then, though, postal codes have been the norm, with countries expanding their formats to accommodate for additional areas.
This is most frequently done by adding digits to the code, a la changing from a 3-digit code to a 5-digit one, and so on. Today, these codes are used for a great deal. They help with geocoding , address validation , and efficient shipping, to name just a few things. They are even used as part of verifying identity and ensuring that things like credit cards aren't being stolen.
So unlike what you learned in high school algebra, these are numbers worth knowing how to use. William Shakespeare once wrote, "A postal code by any other name would smell as sweet. Just like the US calls it a "flashlight" and the UK calls it a "torch," so too are the names of the postal code different depending on where you are. Here are some of the most popular ones:. Formats for these codes vary.
There are some cornerstones that can be laid, and some generalities given on the topic, however. First thing's first: the characters used in the code. Keep in mind that the actual composition of the codes used varies from nation to nation, so not every place is going to use every character.
That said, you can expect these three kinds of symbols:. Most nations use just the numbers and sometimes spaces or hyphens, with varying levels of saturation.
There are some countries though that like to add a little bit of complexity by throwing in the letters, making the code alphanumeric. Here's the list of who uses these swanky alphanumeric codes, in reverse alphabetical order, because we're cool like that:. The way postal codes are written is frequently tied to the locations that they are attributed to.
It's better this way; rather than just randomly assigning numbers and letters and expecting everyone to remember what they mean, well-intended government organizations group things together for easier labeling.
For instance, in the US the first digit in the code which can be anything from 0 to 9 indicates what region of the country the destination is in. ZIP Codes that start with "0" are located in northern New England, while ones starting with "9" are tied to the west coast, Alaska, and Hawaii.
Meanwhile, the first digits of a UK codes are letters, indicating the city or area of the destination: "L" for Liverpool, "RH" for Redhill, and so forth. The thing is, the system varies nation to nation this is starting to seem like a trend. They're not always tied to administrative or geographical borders.
Sometimes they're tied to the old postal zones used in big cities. Ecuador has a couple of those. Then there are ones that are close but not quite; sometimes this means codes that never extend beyond a province's borders, but there are more than one code within it. Many codes are only loosely based on administrative areas, like the US, where the first number gives a reasonable indicator of the destination county. However many ZIP Codes cross county, city, and even state lines. When it boils down to it, postal codes in this category don't really bother confining themselves to the same boundaries used by the rest of the nation's administrative infrastructure.
They put themselves wherever is most convenient for the purposes of running the mail. Now sometimes, codes won't be tied to boundaries at all; they'll be tied to recipients. Here's a few examples.
The Santa Claus example is the true exception—the others will still be tied to the general geographical location where the destination is. Divisions of postal jurisdiction notwithstanding, some codes are more accurate than others. Skip to content. October 10, October 20, Ana Britovsek Kunsek. When were the postcodes introduced?
