Why Do Toll-Free Numbers Start With 800?

Businesses want your call, and a good way for them to get it is to make that call free. Back in the days of slow-returning rotary phones, long before the advent of “touch-tone,” engineers at Bell Labs were thinking hard about future call convenience. The system they devised—which includes 800 numbers—still stands today in this digital age of Skype, VoIP, and cell phones.

"COLLECT" AND "ZENITH" CALLING

Before toll-free numbers, the only way to call free of charge was to call collect. This reversed the charges so that the receiving party paid for the call, not the person placing it. Prior to toll-free numbers, some companies allowed collect calls from customers, but it was a cumbersome way to attract business because the call had to go through the operator.

In the 1950s, a “Zenith number” published and advertised by some companies got you straight through to the operator, who would then look up a big paper directory and place the equivalent of a collect call manually to the receiving number at the relevant area code. This was toll-free for the customer, but certainly far from hassle-free.

NORTH AMERICAN NUMBERING PLAN (NANP)

Developed by Bell and AT&T in the 1940s, the NANP divided North America into 86 numbering areas defined by three-digit codes, beginning with area code 201 (New Jersey) and ending with area code 916 (far-northern California). They cleverly arranged the NANP so that the largest population areas were the quickest to dial on a rotary phone. Utah was assigned 801, but none of the regular area codes ended in a 0, as the astute Bell engineers had kept those ranges aside for special purposes.

Later, these reserved “non-geographic number” ranges—including the magic 800—would come into their own. Why 800, specifically? Probably because the number 8 corresponded with the letter T, for “Toll-free,” on a standard phone dial.

INWATS AND AUTOMATED COLLECT CALLING

In the early 1960s, Ken Looloian, AT&T’s head of planning, had a clever idea to cut costs by using electronic switching. In 1967, AT&T rolled out its long-distance “Inward Wide Area Telephone Service” (InWATS) nationwide. With InWATS, businesses and organizations could “subscribe” (for an expensive, fixed-rate line fee) and receive a number from the toll-free range.

Because of the high cost—ensured by AT&T’s initial monopoly on the service—only large call volume outfits, such as Sheraton and National Data Corp., went for it at first. And it was still a primitive setup by today’s standards. Toll-free numbers were tied to specific geographic areas, forcing serious “subscribers” to pay for up to 20 numbers if they wanted to cover the entire U.S.

Nevertheless, the InWATS service meant that customers could at last direct-dial companies via 800 numbers. Thanks to the automated switching equipment, what was effectively a collect call paid for by the subscriber no longer required operator assistance. This was great news for customers, but probably not so peachy for those polite, trusty, jack-plugging operators.

ENTER THE OTHER MR. 800

The costly, clumsy system was slow to catch on until, in the mid-'70s, AT&T engineer Roy Weber made a big breakthrough in toll-free calling technology. Though computer-controlled digital switching was still in its infancy, Weber’s bold concept (which his supervisor thought was a “dumb idea”) was to point non-geographic numbers at database files. In this way, a number could act as an index code to pull up a specific file, which could then instruct the switchgear to route the call correctly to anywhere. (Unfortunately for Mr. Weber’s pocketbook, AT&T Bell Labs took on the patent rights to all their employees’ inventions there.)

THE 800 AND VANITY NUMBER BOOM

In the early 1980s, using Weber’s insight, AT&T centralized its databases. This was the spark that lit the 800 boom, as it meant that companies could now have a single, nationwide 800 number instead of multiple, state-specific ones. The 800 number became a mark of prestige for companies, and competitive pressures ensured that the service flourished.

It wasn’t long before subscribers got imaginative with their toll-free numbers, choosing catchy “phoneword” combinations, like 800-FLOWERS or 800-COOKIES. These “vanity number” combinations were easier for customers to remember than were long strings of digits. And thanks to touch-tone phones, they were now quick to dial, no matter where they would have landed on the dial of an old rotary phone.

In 1993, 800 numbers became truly portable, no longer tied to a particular carrier. This gave subscribers a much greater choice of memorable and vanity numbers. Due to huge demand, new U.S. toll-free prefixes now include 888, 877, 866, 855 and 844, as well as the original 800.

A WORLD OF 800

Gradually, countries the world over adopted the convention of using an 800 prefix to designate toll-free numbers. An early pioneer of reverse-charge calling and automatic switching, the UK used 0800 for its “Linkline” (later, “freephone”) service which began in 1985 through British Telecom.

In order to free up the greatly prized 0800, BT transferred it across from its previous incarnation as the area code for the remote village of Tongue in the far north of Scotland. Kind of appropriate, in a strange sort of way.

Kodak’s New Cameras Don't Just Take Photos—They Also Print Them

Snapping a photo and immediately sharing it on social media is definitely convenient, but there’s still something so satisfying about having the printed photo—like you’re actually holding the memory in your hands. Kodak’s new STEP cameras now offer the best of both worlds.

As its name implies, the Kodak STEP Instant Print Digital Camera, available for $70 on Amazon, lets you take a picture and print it out on that very same device. Not only do you get to skip the irksome process of uploading photos to your computer and printing them on your bulky, non-portable printer (or worse yet, having to wait for your local pharmacy to print them for you), but you never need to bother with ink cartridges or toner, either. The Kodak STEP comes with special 2-inch-by-3-inch printing paper inlaid with color crystals that bring your image to life. There’s also an adhesive layer on the back, so you can easily stick your photos to laptop covers, scrapbooks, or whatever else could use a little adornment.

There's a 10-second self-timer, so you don't have to ask strangers to take your group photos.Kodak

For those of you who want to give your photos some added flair, you might like the Kodak STEP Touch, available for $130 from Amazon. It’s similar to the regular Kodak STEP, but the LCD touch screen allows you to edit your photos before you print them; you can also shoot short videos and even share your content straight to social media.

If you want to print photos from your smartphone gallery, there's the Kodak STEP Instant Mobile Photo Printer. This portable $80 printer connects to any iOS or Android device with Bluetooth capabilities and can print whatever photos you send to it.

The Kodak STEP Instant Mobile Photo Printer connects to an app that allows you to add filters and other effects to your photos. Kodak

All three Kodak STEP devices come with some of that magical printer paper, but you can order additional refills, too—a 20-sheet set costs $8 on Amazon.

What Is the Citizenship of a Baby Born on an International Flight?

It's pretty standard medical advice: a pregnant woman shouldn’t travel via airplane 36 weeks or later into her pregnancy. Despite that precaution, an occasional bundle of joy may still add an unexpected passenger to the flight manifest. As if giving birth at 40,000 feet wasn't already a stressful experience for a new mom, things can get even more hectic upon landing: Depending on the details surrounding the birth, her newborn’s citizenship could be up for debate.

There is no universal rule for how a country determines the citizenship of a newborn. Some countries just follow the jus sanguinis (right of blood) law, which means a baby’s nationality is determined by that of one or both parents. Others observe that rule and jus soli (right of the soil), where a country grants citizenship to a baby that’s simply born on its soil, regardless of the parents’ origin. These countries are mostly in the Americas and include the United States and Canada. And with the expansion of air travel, these laws had to extend to the heavens as well.

If a baby is born over United States airspace, the jus soli rule means the child would be granted U.S. citizenship, according to the Department of State Foreign Affairs Manual. Depending on the circumstances, the child may also be a candidate for dual citizenship if its parents are from a country that grants citizenship based on blood—though that would depend on the countries involved.

This same simplicity doesn’t extend to a jus sanguinis country, though. This means that an American mother can’t attain French citizenship for her baby just because she gave birth over French airspace. The baby would simply revert to the parent's U.S. citizenship, since the United States also generally follows jus sanguinis when a baby is born to U.S. citizens in a foreign country. Since jus sanguinis is the far more common rule around the globe, most babies born on a flight over international waters or foreign airspace will likely wind up taking the citizenship of its parents.

If there’s a case where the child could potentially be stateless—such as when a mother herself has no official citizenship and the baby is born in international airspace—the baby would likely take the citizenship of whatever country the plane itself is registered in, according to the United Nations’s Convention on the Reduction of Statelessness agreement.

Despite all these complex laws, mid-flight births are exceedingly rare—so rare, in fact, that most airlines don’t even keep track of the number of babies born in the air. An expecting mother likely wouldn't even be able to get onto a flight in the first place, since many airlines have rules that prohibit women from flying after they've reached a certain point in their pregnancy.
