Still-active phreak numbers, all safe and free
- lunaticlabs 5y agoThis reminds me of a weird payphone trick from when I was younger. I grew up in Santa Monica, which had GTE as the local phone provider (I mention this because this trick did NOT work on Pacific Bell payphones). They also owned all the payphones in the area. One day, I was messing around with the payphone after school, and decided to call the AT&T Alliance Teleconferencing number. This was a number where you could setup both an incoming conference call and the owner of the conference could make outgoing calls. It cost more than a dollar a minute per active line, and this was in the early 1990s, so it was really expensive. Anyhow, the phone number for AT&T Alliance Teleconferencing was a weird one, it was 0700-555-1212. Because it had a leading 0 for the number, it wasn't filtered correctly on the pay phones, so you could call it directly. This worked for years before they finally figured it out and filtered it on payphones.

- notpushkin 5y agohttps://www.thisisarecording.com/ATT.html https://www.thisisarecording.com/ATT.html I'm wondering what do these codes at the very end of some AT&T recordings mean? "312 8L" seems to occur on 5 totally different ones.
- billwear 5y agoIf you dig into Evan Doorbell's stuff, he explains this nicely. It has to do with where the intercept was caught (the particular CO / switch level / device).
- morsch 5y agoNot quite in the spirit, I suppose, but you can find out more about most of the numbers by googling them. One guy published youtube videos for a couple of them. Kind of fun.
- irrational 5y ago> all safe That’s exactly what I’d expect a hacker to say ;-) Now, where did I put my Captain Crunch whistle?
- doctorshady 5y agoSomeone set up a strange number with something like this a while ago, with a bunch of randomized recordings. Some of these appear to be inside jokes or otherwise have hidden meanings about unorthodox behavior from phone systems - +1-248-200-0008.
- myself248 5y agoWhat on earth... Do I recognize some of these voices?
- doctorshady 5y agoSome of them are high profile phone people like Evan Doorbell. Others, I'm not sure.

- pimlottc 5y agoTIL 0 decibels ≠ silence
- pxx 5y agoDecibels are only ever a relative measurement on a logarithmic scale. In this case, we aren't even talking about sound (these are dB of power), but this is true independent of base unit. For sound, to represent silence, you actually need -∞ dB. The fact that this is a relative scale is also why your mixer/home theatre receiver represents full intensity as 0 dB and any volume adjustments as some negative number of dB (some mixers may allow you to go a little bit over 0 dB but of course this risks clipping when a full-strength signal comes in). Fun fact though: the sound scale is capped on the upper extreme depending on your environment. You know how recordings of launches of rockets sound like the sound is clipping? It's not hardware limitations. The sound is actually clipping as the pressure hits vacuum. See https://en.wikipedia.org/wiki/Sound_pressure#Sound_pressure_level https://en.wikipedia.org/wiki/Sound_pressure#Sound_pressure_... .
- billwear 5y agoA 0dB tone is a tuning tone. Most amplifiers are tuned to a particular frequency at 0dB, and with a good phone connection, you can even do this over the wire. It's problematic if there are too many hops between you and the source. For example, calling a 0dB tone in a small CO in central Montana didn't give me a usable reference when I was calling from Huntsville, AL, in the 1970's. There were about four hops in there.
- reaperducer 5y agoIt has the Hall and Oats recording number, but is missing the one for They Might Be Giants. Does anyone know if it's still active? TMBG used to release all of their new music on an answering machine before you could buy it. Kind of a pre-internet version of artists releasing singles on YouTube before you can buy the album.

- ugl 5y agoThe old mci number, died last year finally unless there's another still up
- doctorshady 5y agoThere's a few: 800-437-7950 800-223-1104 (passcode 910777)
- notpushkin 5y agoFor the second one, I'm getting "Please, enter your password", then, after typing the passcode – "The toll-free number you have dialed has been disconnected. No further information is available about this number. 074T"
- doctorshady 5y agoWhatever method you're using to send touchtones is likely not working then. You might want to try using something else to send it.
- MockObject 5y agoI'm getting the same error.
- paulluuk 5y agoIn case anyone else wants to try this from outside the US: dial 001 (or +1) followed by the number, including the part between parentheses.

- sandreas 5y agoI would suggest to put in a <a href="tel:2027621401">(202) 762-1401</a> so that they maybe would be really click-dialable :-)
- 0x0 5y agoShould probably be "tel:+1...."
- TazeTSchnitzel 5y ago> (800) 444-4444: automated number announcement circuit Is this meant to announce your own number back at you? I called from outside the US and got a very different number from my own, which is fascinating.
- rahimnathwani 5y agoDid you call directly, or use a calling card or similar discount call service?
- TazeTSchnitzel 5y agoDirectly from my mobile phone. I wonder if the number I got is the notional phone number of a virtual international trunk line or something like that.

- greenyoda 5y ago> (914) 232-9901: pleasant hills DMS 100 In the NYC vicinity, dialing the -9901 suffix on many phone exchanges will give you a recorded message identifying the central office you reached. For example, if you call (212) 736-9901, it tells you that the switch is on West 36th Street[1] and a list of area codes/prefixes it serves. Amusingly, the switch still identifies itself as "Bell Atlantic", which is what the local Regional Bell Operating Company was called before it became "Verizon" in 2000 (it was also briefly "NYNEX").[2] [1] This building, apparently: https://skyscraperpage.com/cities/?buildingID=69989 https://skyscraperpage.com/cities/?buildingID=69989 [2] https://en.wikipedia.org/wiki/Verizon_Communications#Bell_Atlantic_(1983%E2%80%932000) https://en.wikipedia.org/wiki/Verizon_Communications#Bell_At...
- tiernano 5y agoNYNEX: just clicked that's what Phantom Phreak from Hackers was on about: "the Phantom Phreak, king of NYNEX". And looking at the dates, seems to gel... took me that long to figure out what was said there!
- icedchai 5y agoThis makes me feel old. I remember seeing Hackers in the theater, when it came out, back in 1995. NYNEX was the local RBOC. Broadband wasn't a thing yet, and everyone was still on dialup.
- deleted 5y ago[deleted]
- myself248 5y agoAs far as I've seen, the RBOC names persist in regulatory filings and stuff; I believe any names newer than that are pure marketing.
- icedchai 5y agoBriefly? The New York / New England RBOC was called NYNEX for most of the 80's and 90's, a lot longer than it was Bell Atlantic. Bell Atlantic was just a 3 or 4 year thing after it acquired NYNEX.
- gormandizer 5y agoIn addition to the USNO master clock there are also WWV Colorado: 303-499-7111 WWV Hawaii: 808-335-4363
- 13of40 5y agoI'm always astonished that after 30 years and the installation of two giant data centers, this little Oregon town hasn't upgraded its telephone exchange. Anyway, here's an automated ghost from the past: 541-447-0054
- mmaunder 5y agoThis makes my heart smile. Rarely these days I’ll connect with a phellow phreak and we chat about bridge parties and other fun stuff. One day the fone number will be a thing of the past and all this an ancient memory.
- mmaunder 5y agoI find myself wondering if CCITT5 tones are still in use on international trunks. Anyone know? Any old BlueBeep users here?
- myself248 5y agoP80Box was a lot more compact than BlueBeep :P At one of the HOPEs, someone brought a bunch of 8-bit machines and set them up in the mezzanine. Among them was a TI 99/4A, which for all its failings, had a very nice sound chip accessible from TI BASIC. And, bless whoever brought it, the TI BASIC quick reference card was tucked under the machine, which was all I needed to jog my memory. I implemented a quick tone-dialer with DTMF and redbox tones, adjustable twist, and a few other features. Since there was no tape deck and everything was just resident in RAM, I fully expected that someone would reboot the machine and do something else with it moments after I walked away. It was fun in the moment, that's all I wanted. Much to my surprise, I came back several hours later and there were folks playing with the dialer, and to my even greater surprise, someone had extended it with MF and bluebox tones in the interim!
- ButterWashed 5y agoI always enjoy reading about this kind of stuff even though a lot of is only applicable in the US. On UK landlines you can dial 17070 to access BT line test functions. When you dial a very well spoken voice reads your phone number back to you. It's rarely been useful to me but I did once astonish someone by using it, they were convinced it was meant to be a secret number and that I was probably breaking the law!
- garciansmith 5y ago(270) 301-5797 is related to Kentucky Route Zero. The number is found in the game, and I was pleased to see you could actually call it.
- throwawayHN378 5y agoAre you the author? You you can make them callable links
- zxcvbn4038 5y agoI had a lot of fun with lists like these in the 70s/80s. To this day I give all of my creditors a phone number which I know has rung busy since 1983 thanks to lists like these. It would be very interesting to war-dial all of the US exchanges in 2022 to see what answers.
- hahamrfunnyguy 5y agoIf you like learning about telephone system, phone phreak Evan Doorbell has a very interesting series of podcasts about his time exploring the telephone system in the 1970's. The podcasts include his recordings from that time period. It was neat to hear some of the old tones and recorded messages I grew up with, as well as ones that were well before my time: http://www.evan-doorbell.com/production/group1.htm http://www.evan-doorbell.com/production/group1.htm
- jimmaswell 5y agoI found him on YouTube. Really interesting to listen to the analog network and how the long distance system worked.
- billwear 5y agoyeah, I love Evan's stuff, especially the recordings about George, the answering machine, and random answering machine outgoing messages from the 80's Atlanta area. fantastic!
- plapsley 5y agoHis "How Evan Doorbell Became a Phone Phreak" series is fantastic: http://www.evan-doorbell.com/production/#phonephreak http://www.evan-doorbell.com/production/#phonephreak
- 8bitsrule 5y agoYeah! This stuff is a total gas. Here's this professional-broadcaster-quality voice, narrating a personal story about 50 year-old recordings of noises made by equipment that doesn't exist any more. (With threats by 'Ernestine') So: pure entertainment. After the series of many narrated tapes, there's another series of raw tapes (unnarrated ... test what you've learned).
- sen 5y agoWell that was an awesome rabbit hole to go down, thanks.
- throwaway984393 5y agoThe magic of the PSTN was you could work your way into the bowels of the Military and talk to a guy guarding nukes just by dialing the right number and bullshitting. Today you can't really social engineer your way into unauthorized access on Slack, for example (you have to have an account first). I suppose e-mail is the final remnant of the information wild west. Well, that and public ELK stacks...
- psanford 5y agoBack when payphones were still a thing, one prank I enjoyed was to dial 991-$(last 4 digits of the pay phone's phone number) from a payphone. Then you would hangup, pickup, and hangup again. Then a few seconds later the payphone would start ringing. I have no idea what this was actually doing. Does anyone have any knowledge of how this worked? I don't even remember how I learned this trick. Presumably I learned it from some other kid, but who knows where the knowledge originated from in our teenage social circle.
- l8rlump 5y agoIn Australia back in the day, you could dial 199 on a pay phone which was the ring back number. Hang up, let it ring twice and then answer it. If you did it right there would be a warbling tone in the earpiece and you could then make any call for free.
- notreallyserio 5y agoLooks like it was a feature used for testing: https://en.wikipedia.org/wiki/Ringback_number https://en.wikipedia.org/wiki/Ringback_number
- psanford 5y agoYes, that seems to be it. Thanks!
- jhpaul 5y agoI remember a long evening on the Ocean City boardwalk spent doing this to a payphone and waiting to see who would walk by and pick it up.
- malingo 5y agoPayphones are still a thing in northeast LA. It's incredible. Most have been vandalized or destroyed but many still work. See https://www.instagram.com/payphonesoflosangeles/ https://www.instagram.com/payphonesoflosangeles/

- jamal-kumar 5y agothe three funnest things i did in the waning age of the phreak era in the mid-2000s in highschool: 1. finding this test extension number, xxx-4111, which i broke the truancy bot with which would call everyone's parents who had skipped class that day from the nortel meridan pbx and inform them that their son or daughter (name) was skipping (period). this test extension number cut out the line for noise testing completely for a few minutes, so the bot would just skip people ahead of me too whenever i would skip class (Almost every day, I had more fun taking girls out to do bad things after convincing them I broke the robot, zero regrets). I think it's called a silent termination test line - you might be able to find your own here: https://www.sandman.com/colookup https://www.sandman.com/colookup 2. finding another number on that test extension. i think it was xxx-8111, and since this was a toll free extension this was dialable for free from payphones. you waited like 30 seconds hearing nothing but silence, then a dial tone. you could dial anywhere for free with this. none of the phone company employees i've asked seems to know wtf this was but the school was close to a headquarters so i'm just thinking we were on the same trunk. and back then, you could just download gargantuan phone number lists in .txt format from people with waaaaaaaaay too much time on their hands like phonelosers for fun numbers to call. was hilarious when some friend of mine made the mistake of trying to print this out cause it was filled with obscenities and stuff without realizing it was goddamn reams of paper. he used some dead kid's account though so he didn't get caught. haha i think the guy who did those lists went to jail, rbcp? 3. getting onto my school's intercom. *, 5, 1 and boom that was it. I found it handscanning. I only went on to actually say something the last day and I just pretended like I was crazy when I was caught so they let me go. I think the girl who went on after me was like GRAD '07 WOOOOOOO! I think a couple of these could still be done.

- kelp 5y agoOnly slightly related, but a story from back when pay phones were still a common thing. My first or second year of high school I lived in a rural town in Washington state with very little to do. But it was also a tourist destination. In the summer me and my friends would just sit around downtown (this was 1 street with a 4 way stop) trying to figure out what to do with our days. One day the pay phone was randomly ringing and we picked it up. It was two girls, near our age, who were also bored and had written down the number of that pay phone and were randomly calling it. They were from out of town (if they lived there we'd have known them, it was that small of a place) and staying at their grandfathers funky vacation home just a couple of miles away. We ended up meeting up with them and got up to all sorts of trouble that summer. We were friends for years and years after. I'm still occasionally in touch with one of them, over 25 years later. Just a completely random way to meet some new friends that I can't imagine happening anymore.
- rrickardt 5y agoPlease be gentle on these numbers, you already know what HN hug of death is capable of :). It might be quite ancient relays switching it.
- Symbiote 5y agoThe numbers could be made diallable directly from the web page by adding links: <a href="tel:+1-800-444-4444">(800) 444-4444</a> (The +1 is required.)

- hacknewslogin 5y agoI cam into this scene pretty late(early 2000's) but I loved playing around with payphones. I have a great memory of calling random 1800 numbers until I found one that gave me back a dial tone! I was so excited I called a friend of mine. He didn't care at all lol. The PLA phonebook was a blast too. For one of my birthday parties my friends and I huddled around a phone and called elevators, bowling alleys around the country, and prank called a few embassies. Does anyone have a lead on a download link for the PLA BBS? I would love to play around with it again, maybe host my own version.
