How 80s Pagers Worked, and What 143 and 07734 Meant

In 1987, sending someone a message took a whole routine. You picked up a touch-tone phone, dialed their pager number, waited for the beeps, typed your own phone number and hit the pound key. Then you hung up and sat by that phone, because the other person now had to find a pay phone and call you back.

It sounds like a punishment, but for a while it was the quickest way to reach someone away from a phone. The radio trick behind it was clever, the number codes were half the fun, and in 1988 schools started treating the thing like contraband.

Where the beeper came from

The first telephone pager system was built in 1949 by Al Gross, an engineer born in Toronto, and it was meant for doctors. Doctors weren't sold. Reportedly they worried a beeping box would upset patients.

The first practical service started in the New York area in 1950. Physicians paid $12 a month for a 7 ounce pager that worked within about 25 miles of a single tower. Motorola coined the word "pager" in 1959, and in 1962 the Bell System showed off the "Bellboy" at the Seattle World's Fair. It only buzzed. To get the message, you called the service center.

Motorola's Pageboy I, from 1974, was Motorola's first consumer pager that really sold. It had no screen and couldn't store anything. By the 80s pagers could show numbers, and in 1986 Motorola released the Bravo, a numeric pager its own timelines describe as becoming the world's best selling pager.

How a pager actually worked

The clever part is that every pager in the city heard every page. The chain went like this:

1. You call. Each pager had its own phone number. Your call reached the paging company's computer.

2. The network shouts. The computer looked up that pager's ID, called a capcode, and broadcast your message over the radio. Many transmitters sent the same signal at once, and a pager simply locked onto the strongest one.

3. Only one pager listens. Every pager on the channel received the broadcast, but each one only reacted to its own capcode. Think of a teacher calling a name in a full classroom. Everyone hears it, one kid stands up.

4. Beep. When the address matched, the pager beeped, flashed or vibrated and put the number on its little LCD.

A common standard was POCSAG, developed by the British Post Office in the late 1970s and usually run at 1,200 bits per second. That's slow even by dial-up standards, but a phone number is tiny.

It was strictly one way. The network had no idea if your page arrived. The upside: paging transmitters pumped out around 1,000 watts, compared with well under a watt for a cell phone channel. That's why pagers worked deep inside buildings where phones didn't.

Tone, numeric, alphanumeric

Tone only. The original "beeper." It made a sound or vibrated, and that was it. You called your office or answering service to find out why.

Voice. Played back a short recorded message, about ten seconds.

Numeric. The 80s classic. A row of digits on an LCD, usually a phone number, sometimes with a code tacked on.

Alphanumeric. Showed actual text, but someone usually had to go through an operator or a terminal to type it in. These took off later.

143, 07734 and the other codes

Once people had a screen that only showed numbers, they started writing in numbers. There was never an official list. Codes changed from one friend group to the next, and homemade dictionaries got passed around. A few showed up everywhere:

143 meant "I love you," counting the letters in each word.

07734 meant "hello." Turn the pager upside down and read it. The trick came straight from calculator words.

911 meant call me right now.

411 meant I've got news.

People also stuck their own code after a callback number so you'd know who it was and how urgent before you went hunting for quarters. That 0.7734 joke is printed on our Hello Ringer 1984 ($39.99), on a little LCD panel, for anyone who still reads screens upside down.

Doctors, dealers, then teenagers

Early users were the people who had to be reachable: doctors first, then, as a 1983 New York magazine piece listed, construction workers, repairmen, pilots and flight attendants. The same piece listed drug dealers.

That second group took over the image. In 1986 a Los Angeles deputy district attorney told Time that beepers were "the single most common tool of the drug trade." A narcotics officer blamed TV, saying crooks copied what they saw criminals doing on shows like Miami Vice. Pay phones became part of the story too. In St. Paul, the phone company swapped some touch-tone pay phones for rotary ones so nobody could dial a pager from them.

Then came the school bans. In 1988 a Dade County schools official told the New York Times the beeper was "the most dominant symbol of the drug trade." Prince George's County and Baltimore schools banned students from wearing them. In November 1988 Chicago banned beepers in public and private schools, with fines of $200 to $500. New Jersey went further and later passed a law with up to six months in jail for students carrying one at school.

The irony came in the 90s, when Motorola started selling pagers to parents as a way to keep track of their kids.

How big it got

Around 3.2 million people worldwide had a pager in 1980. By 1990 it was more than 22 million, and by 1994 more than 61 million. In the US, pager sales jumped 25 percent in 1987 alone. By 1999, about 45 million Americans carried one. In the 80s, service ran tens of dollars a month. By 1993, a basic pager cost about $100 plus $11 to $17 a month in service.

Cell phones won by the late 90s, and Motorola announced it would stop making new pagers in 2001. The habit of clipping a gadget to your belt stayed. So did the digital look: if your wrist misses a small LCD, the Black Digital Watch 1982 ($22.99) and the Digitron Watch 1982 ($39.99) are the closest thing to a pager we sell.

Why hospitals still beep

Pagers never fully died. A 2017 survey of 620 US hospital clinicians found nearly 80 percent had been issued a hospital pager. The UK's NHS was using about 130,000 pagers that same year, roughly a tenth of all the pagers left in the world.

The reasons are the same ones from the 80s: a strong signal inside thick buildings, long battery life, and a network that keeps working when cell networks jam up in an emergency. Volunteer firefighters and rural first responders still carry them. So do the restaurant buzzers that tell you your table is ready.

Questions we get

How did pagers work in the 80s? You called the pager's phone number and typed in a callback number. The paging company broadcast it by radio to every pager in the area, and only the pager with the matching ID beeped and showed the number.

How did you send a message to a pager? From a touch-tone phone: dial the pager number, wait for the tone, key in your number and any code, press pound and hang up.

What does 143 mean on a pager? "I love you," from the number of letters in each word. 07734 read upside down spells "hello."

Why were pagers linked to drug dealers? Dealers adopted them early in the 80s, and by 1988 news reports and school officials treated beepers as a symbol of the drug trade. Several school systems banned them.

Do doctors still use pagers? Many do. A 2017 survey found nearly 80 percent of US hospital clinicians had been issued one.
