PCO Full Form
Public Call Office
What does PCO stand for? A general term, explained.
PCO Full Form in English, letter by letter
PCO (Public Call Office) was a licensed street-corner phone booth in India where people paid per call before mobile phones spread.
PCO Full Form in Indian Languages
Before smartphones, the yellow PCO board on a street corner was how many Indians made a phone call. PCO stands for Public Call Office, and the name is given here in six Indian languages.
The booth that carried a generation's calls
A Public Call Office was a telephone point run by a private person, where anyone could make a call and pay for it. For decades a home landline meant a long waiting list, so in many villages and neighbourhoods the PCO was the only phone within walking distance.
The owner's phone was connected to a meter that recorded the length of each call. When the call ended he read out the charge. Calls were priced by distance, and a call to another city cost far more than one within the town.
The best known board read STD-PCO, and later STD-ISD-PCO. It told a passer-by exactly what the shop could do, and rates were often painted or printed on a chart behind the counter.
STD, ISD and local: what the counters offered
STD is Subscriber Trunk Dialling, the system that let a caller dial long-distance numbers directly with the area code, instead of booking a trunk call through an operator. ISD is International Subscriber Dialling, which allowed calls abroad in the same way.
A local call was the cheapest, an STD call to another city cost more, and an ISD call to the Gulf, the UK or the US cost the most. Migrant workers and families with relatives abroad were the biggest users of ISD booths.
How a PCO was started and run
Telephone connections were issued by the telecom department or later by private operators, and a PCO owner took a commercial connection with a meter. After the telecom policy of 1994 opened the sector to private players, STD-PCO shops multiplied quickly across towns and villages in the late 1990s.
The business needed little capital: a phone, a meter, a stool and a signboard. Owners earned a commission or margin on each call, and many added a photocopier, a fax machine or a small stationery counter to keep the shop busy between calls.
For many families, especially in smaller towns, running a booth was a full income. Some booths employed local youth, and some were run by people with disabilities under government schemes that gave them a licence for a livelihood.
What the PCO meant for ordinary families
For migrant workers in cities and students in hostel towns, the PCO was the link home. On Sunday evenings there were queues outside the busiest booths, and the owner often knew which family called which village every week.
Messages for people without phones went through neighbours. A caller would ring the village shop or a neighbour's number and ask for someone to be called to the phone. This is why many people can still recall their relatives' PCO numbers by heart.
Public telecom companies such as BSNL and its predecessors also ran booths, alongside the private ones. A village without a booth could ask the telecom department to place one under a scheme for rural telephony.
How mobile phones ended the PCO
Cheap handsets and cheap calls changed everything. Reliance launched a Rs 501 CDMA phone in 2003, and prepaid plans and falling handset prices through the 2000s put a phone in many more hands. Call rates fell steadily, and a mobile call became cheaper than a call from a booth.
The last push came in 2016, when Reliance Jio launched with free voice calls on a 4G network. By then the PCO had few reasons to survive. A few still exist at railway stations, bus stands and remote areas with weak coverage, now selling recharges and offering money-transfer services.
Where you still see the term
Old signboards, films and photographs keep the acronym alive. It still appears in exam questions, in older government papers and in the phrase 'go to the PCO and call', which an older generation grew up with.
For anyone studying India's telecom story, the PCO shows how quickly access can change from a scarce service to something nearly everyone carries. A person who queued at a booth in the 1990s can now video-call from a pocket.
Words and habits the booths left behind
Many people still say STD for a long-distance call, even after the system changed. The missed call as a form of communication also grew in the same era, when a call was costly and a signal could be sent by letting the phone ring once and cutting it.
The trunk call booking also belonged to this period. A caller would book a call with an operator and wait for it to be connected, sometimes for hours. These terms now appear mostly in old films and in family stories.
The PCO shows what Indians did when a phone was within reach: they paid to stay in touch. The yellow boards have mostly gone, but the habit they built is what the mobile market grew on.
PCO Full Form: Common Questions
What is the full form of PCO?
Public Call Office. It was a licensed public telephone booth, usually run by a private owner, where people paid for each call.
What does STD stand for in STD-PCO?
STD is Subscriber Trunk Dialling, which lets a caller dial long-distance numbers directly using an area code. ISD is the same idea for international calls.
How much did a PCO call cost?
It depended on distance and the rates of the time. Local calls were cheapest, STD calls cost more and ISD calls cost the most. Rates varied by period and operator, so there is no single price.
Are there any PCOs left in India?
A few remain in places such as railway stations and remote villages. Most have closed or turned into recharge and money-transfer shops.
What replaced PCOs in India?
Mobile phones. Cheaper handsets, falling call rates and then Jio's free voice calls in 2016 made the booth unnecessary for most people.
Why were PCO boards yellow?
Yellow was the common colour of PCO signboards and made them easy to spot from the road. The colour became closely linked in memory with the STD-PCO booth.
