Pakistan is a country located in the Middle East, which borders with Iran, Afghanistan, China and India. The country was founded in 1947 by parts of British India. For 100 years the country was part of the British Empire. In 1956 the independent state proclaimed itself the first Islamic republic. Pakistan was founded with the aspiration of representing a country for all Muslims in the Indian subcontinent, a central idea, to keep the different people of the country together. In that days, the Bengal Indian-British province, called East Pakistan that was 1,500 kilometers apart, was part of the state. In 1971 after the war conflicts, Eastern Pakistan became Bangladesh's independent state. The huge distance between the two sides, considering that India was full, made it difficult to develop a national identity. In addition, the West is characterized by Muslim prevalence, while the Orient is predominantly Hindu. The constitution of a united state has become an illusion. Young Pakistan faced similarly bloody conflicts with India over the province of Kashmir in the northern part of the country. Parts of the country are still claimed by China, India and Pakistan. Here are the partially autonomous areas of Jammu and Kashmir. Pakistan's political stability is still to be considered inadequate.
The history of the Post of Pakistan is very old. Already in the twelfth century there are precursor models of mail in these areas. A messenger system was set up for deliveries of the shipments, which were calculated on the basis of the weight of the goods and the distance of the route. In the 18th Century under British rule a more modern system was set up, which used camels as transport vehicles, respectively railway lines. Today, the postal system is run by the State Post Pakistan, which was founded after independence from the United Kingdom.
The postal code system was introduced in Pakistan in 1988 to deliver a faster and better postal service. Pakistan's ZIP code consists of a five-digit numeric code, which is associated with their postal centers. Pakistan is divided into four provinces: Balochistan, Khyber Pakhtunkhwa, Punjab and Sindh; It is also part of the country Islamabad besides the tribal areas under federal administration, although above all these bordering parts of Afghanistan are partially controlled by al-Qaeda or the Pakistani Taliban. The first two digits of the ZIP code refer to the respective province, the following three digits to the district or to the associated post office, GPOs (General Post Office):
In Pakistan, postal codes were introduced on January 1, 1988, to make sorting and delivering mail faster and more efficient. The Pakistan postal code is a 5-digit code placed at the end of an address, enabling automated sorting for a specific post office or address. A postcode is also called a postal code or zip code
With a population of over 200 million, Pakistan stands at the 5th number in the list of most populated countries in the world. The Islamic Republic of Pakistan is a sovereign country in South Asia. Being the 5th most populated country in the world, it covers the area of 796,095 square kilometers being the 35th largest nation on the planet. Postal code or postcode is a combination of numbers and letters that is used to sort mails when posting.
In Pakistan, the postal code is a 5-digit number that is added at the end of the shipping address to speed the sorting and delivery of the mails. It was introduced in 1988 in Pakistan. These codes are assigned to the post offices where the receiving address of the mail falls.This postal code can be used as a combination of both or sometimes the postal code can consist of only one of them. Sometimes there can be spaces or punctuation or both included in it to make it proper. The dataset shows the following information for each row:
To make the mailing system convenient for the future, out of 190, 117 members of different countries if the universal postal union decided to have the system of postal code. This happened in February 2005.
Most of the time the postal codes are assigned to a special geographical location. Other than that, some special locations or individuals also get their special codes. This is done for places like local commercial companies and government agencies where a lot of mails are received.
Postal/zip codes around the world don't follow a common pattern. In some countries they are made up by numbers, in others they can be combinations of numbers an letters, some can contain spaces, others dots, the number of characters can vary from two to at least six...
What you could do (theoretically) is create a seperate regex for every country in the world, not recommendable IMO. But you would still be missing on the validation part: Zip code 12345 may exist, but 12346 not, maybe 12344 doesn't exist either. How do you check for that with a regex?
It is not possible to guarantee accuracy without actually mailing something to an address and having the person let you know when they receive it, but we can narrow things by down by eliminating cases that we know are bad.
Please note that this is quite a hard problem, as stated by the accepted answer.I guess it didn't deter the folks at geonames.org though.They have a file a country info file, which doesn't fit whole into this answer - limit is at 30000 chars apparently. There are regexes for about 150 countries.
As others have pointed out, one regex to rule them all is unlikely. However, you can craft regular expressions for as many countries as you need using the address formatting info from the Universal Postal Union -- a little-known UN agency.
The problem is going to be that you probably have no good means of keeping up with the changing postal code requirements of countries on the other side of the globe and which you share no common languages. Unless you have a large enough budget to track this, you are almost certainly better off giving the responsibility of validating addresses to google or yahoo.
Given that there are so many edge cases for each country (eg. London addresses may use a slightly different format to the rest of the UK) I don't think that there is an ultimate regex other than maybe:
Why are you doing this and why do you care? As Tom Ritter pointed out, it doesn't matter whether you even have a ZIP/postal code at all, much less whether it's valid or not, until and unless you are actually going to be sending something to that address. Even if you expect that you will be sending them something someday, that doesn't mean you need a postal code today.
Going to post the current code from 2024 here as it's best practice on SO not to rely on links... but really the WC project is well maintained so you should probably grab the latest updated version there in the future.
I know this is an old quesiton, but I stumbled across the same problem.I have invoices from over 100 countries and am trying to get the correkt creditor over the zip (if every other check is failing).So what I did is writing a short Python Script, that creates a pattern from a string:
With that I created all the different possible regexes for all zips (by country) we have historically and wrote them back into a db table (i.e. something like this in the end:COUNTRY:RE PATTERN:(\d5)\b [what ever country this might be ;D])
Each and every area in Pakistan has been assigned with a post code to minimize mis sending of the mail and speedy sorting. Searchable post code directory of delivery and nondelivery post offices can be found here.
