I don't think I've ever seen these types of numbers in the GV number pool. Are they just scooped up rather quickly, or is there something more sinister going on?

I host over 50 VICIdial servers and provide DID's and VoIP Termination to a variety of clients. I've seen performance drop off a cliff the last 90 for those that don’t want to play by the rules. YOU will get blocked or flagged. so... Play by these Rules!

1. Every number you use as a caller ID must be able to receive a call back. A valid working number.
   
2. Keep you drop percentage under 8%, 3% to be legal. try your best.
   
3. for high value leads, leave a short real voicemail. "This is bob, call me back." they want to see this. Hang-ups get flagged. For low quality leads answering machine detection is still a thing.
   
4. Set your ring time to an odd number. not 30 pr 60 seconds. Don’t look like a machine.
   
5. Don’t call a lead more than once per day with the same caller ID
   
6. "If " you are compliant and legit. Register your business and numbers with the Mobile carriers. Here’s a list. https://www.freevoice.techregister-caller-id
   
7. Widen your local presence to the full state. If all calls from a caller ID only go to the same NPA or NXX, you're doing what the scammers do... you'll get flagged using their played-out tactics.
   

8, Use bigger more expensive Tier 1 Carriers, If your call is coming from a discount carrier that passes a lot of low quality traffic to the PSTN, you're guilty by association. Premium carriers get blocked and flagged less.

1. Stir Shaken - don’t get DID's from Carrier A and send calls out Carrier B. keep it all from the same carrier.

I have been receiving texts from a number that has been harassing me, the person is claiming to know me and says they have watched me and want to ‘look down on me’, very weird, I can pm anyone the phone number and I just need help because I don’t know this person and I just want to know if I might have come in contact with them
Edit :I have their number, a name and a city but I’m no where near finding out who this is. I managed to get the rate center, LATA, ILLEC name, CLLI, NPA-NXX,Carrier, Line type, OCN and prefix type however I don’t know what any of that means or what it does and this person won’t tel me who they are or how they supposedly know me , is this information even helpful?

In opposition to what most Americans are probably going to accept, region codes exist beyond the US. There are 405 region codes on the planet: 326 in the US, 42 in Canada, 17 non-geographic, and 20 others. The greater part of the other region codes are in the Caribbean. Nonetheless, some are situated in the Pacific including 684 (American Samoa), 671 (Guam), and 670 (Northern Mariana Islands).
California is the state with the most region codes at 34 followed by Texas (27), New York (19), Florida (17), and Illinois (13). 12 US states just have a solitary region code. While no area codes in the US cross state limits, 3 region codes in Canada cross territory limits.
In the US and its regions, Canada, and the Caribbean, the association and allotment of phone numbers is administered by the North American Numbering Plan Administration (NANPA). NANPA coordinates the allotment of region codes and phone prefixes to different telephone organizations. The essential configuration of a telephone number in any of these nations is NPA-NXX-XXXX or (NPA) NXX-XXXX.
NPA: Area codes came into utilization during the mid 1940s. NPA codes were created by AT&T and the Bell System to partition the inclusion region into "number arrangement regions" (truncated NPA). NPA codes are all the more ordinarily alluded to as region codes. While the framework was created during the 40s, direct dialing of significant distance didn't start until the mid 50s. Some region codes are saved for specific purposes. For example, region code 800 (regularly alluded to as 800-numbers) is held for complementary calls where the called party is charged rather than the calling party. Likewise, not all region codes are right now being used.

NXX: The following three digits of a landline number or cellphone number are known as the NXX. The NXX is otherwise called the prefix or trade. Different phone transporters will hold blocks of phone numbers by saving a NXX inside an area code. Like region codes, not all prefixes are at present being used.
Supporter: Finally, the last 4 digits of the telephone number are known as the endorser or neighborhood number. In view of the absolute number of dynamic NPA and NXX blends held and that every one could have up to 10,000 potential endorser numbers, the ongoing all out conceivable number of phone numbers is 1,699,140,000. In light of the all out populace of the US and Canada as per the US Census and the World Bank, that leaves 4 telephone numbers for each individual. Recollect however that telephone numbers are not generally only utilized for standard home telephones. Many phone numbers are presently utilized for fax machines, PDAs or remote telephones, or web associations so one individual may really require numerous telephone lines.

Hi. I am trying to setup area code blocking for the Caribbean islands that use NPA-NXX. In the past this region has been a hot bed for toll fraud and I would just like to disallow outbound calls from the tenant (blocking international as well). Any ideas how to block a particular area code? Using direct routing but ATT is saying it not done on their side.

i'm simply a curious study'er. ive researched a lot about npa-nxx blocks.
the recycling pools have to be stored somewhere physically, as with everything of internet.
and if the physical server was destroyed somehow, then a big chunk pool of numbers would vanish, including our own active personal numbers.

Over the past 6 months or so, I have started getting a handful of spoofed SMS messages with obscure links in them. Obviously somebody is registering a whole bunch of random letter domain names and hoping people will click on custom links confirming that the text messages are being read but a human. The scam blocking stuff does a pretty good job of catching them.
My question is: how are they spoofing US numbers? The NPA/NXX of the sender usually goes back to some wireline LEC somewhere (not a VoIP provider). So the numbers should not even be usable for SMS, right?
There only way I can think of for this to happen is for these to be originated outside the US as roamers on other networks. But even that should be caught locally, right?
Anybody have any insight as to the technical piece behind how this is done?

I just set up something on my phone to make refills easier. The pharmacy I use hasn't updated its voice response prompts in years. So I know the routine: dial the pharmacy, enter 2 for refills, enter the Rx number, select 1 to confirm the Rx, select 1 to accept their offered time for pickup. Your pharmacy probably uses a similar - but perhaps slightly different prompt. I added a contact to my phone called Meds Refill with the following number: 1,NPA-NXX-LINE,,,2,,,1234567,,,1,,,1
For me sometimes I know I need a refill, but I don't have the Rx number handy so I don't call in. Or I call, enter the Rx number incorrectly, and get stuck in the prompts waiting to reenter it. Or I forget completely and rush to the pharmacy last minute and end up waiting on the pharmacist. Having the number pre-programmed for me solves most of these issues for me.
To test it out I used it for my refill this month and it worked so smoothly - all I had to do is listen at the end to hear when to pick up.
I hope this tip works for some of you!
P.S. Set the contact number up using commas for a brief pause. Tweak the number of commas to match the prompt timing so your input occurs when the system is listening for it. In my example, 1,NPA-NXX-LINE is your pharmacy phone number. 1234567 is your RX number. The menu options and confirm options will vary based on your pharmacy.

We're a niche company in a niche industry. We only sell services, not hardware/equipment.
Lately we've been getting a lot of messages via our website's "contact form" and a few via our "support" email address that fall into the same basic pattern of

• Listing a random collection of equipment relevant to our industry
• Asking for a quote urgently
• Signing the email with a name that appears to be "real" but with a website and contact information that seem close-ish to the real details but don't match.
  
• The user agent IP Address is also usually assigned and/or geolocated to somewhere very different than where the user claims to be (i.e. user clams to be in California but IP belongs to an Indian DSL account)
  

I'm trying to figure out what the scammer's goal is -- if we did actually provide a quote...they still wouldn't have anything.
For example (with some details masked -- noted in [] and italics:

Fax:(916) [NXX that shows as being assigned for Cellular to MAP Mobile Communications]

Obviously we're just letting them fall into the bit bucket but I'm curious what the payoff is to be worth setting up a fake domain, getting fake phone numbers in place, in some of the other cases a fake address (UPS-store type PO box or virtual office) etc.

Does anybody know if there is a SOC code or other network/provisioning setting to deliver text messages as +1-NPA-NXX-XXXX instead of the default of NPA-NXX-XXXX. T-Mobile and AT&T deliver messages to the handset in E.164 format and it seems Verizon hasn’t hopped on board as of yet.

I'm considering getting a cell phone with a number outside of the area code I reside in.
My question pertains to the reliability of that number if there's some sort of environmental catastrophe like a hurricane occurs and if I would still be able to make and receive calls on said cell phone.
Example: I live in San Antonio, TX, but have a phone with a Houston, TX, area code. If a hurricane impacted Houston, would I, living in San Antonio, still be able to make and receive calls even if the central office in the NPA/NXX my phone number is in was out of service?
I'm not a telecom engineer and was hoping someone with that level of knowledge could answer the question.
Thanks.

831-245-0835. . I would just report this to their carrier provider.

Seems to me that calls only get properly processed when I dial them as 1-NPA-NXX-XXXX rather than NXX-XXXX (or even NPA-NXX-XXXX) as I usually do for local calls. Kinda frustrating, maybe they'll change it eventually

Getting too many spam calls of late. Most have my NPA-NXX so they should be easy to filter.
I'm looking for a call blocking app that can do the following:

1. Block calls with a caller ID that starts with the first 6 digits of my phone number
2. Does not reject the blocked calls to voicemail, but rather disconnects the call instead.

Du Caller has the disconnect feature, but not the NPA-NXX blocking. Hiya and Truecaller have the NPA-NXX blocking, but reject calls to vm and then I still have to go in and delete the vm that gets left.
Is there anything out there that does both?
I have an unlocked Samsung Galaxy S7 on T-Mobile, so I don't think there's anything native in the phone that would help with this.

I've been receiving countless calls from a spam account. Not sure where, what, why, etc. I've had this issue for over a year now, and it's coming into contact with things as simple as retrieving an order from a driver for food.
I've reported the numbers to the FTC, placed my number on the do-not-call list, among blocking them, only to receive a similar phone number under the same NPA-NXX prefix, as well as blocked them from my phone, only to receive more phone spoofs, sometimes including my own phone number!
I was thinking that changing my phone number would make things easier, but it's more of a last resort for me. What other ways can I do to mitigate these neighbor-spoofing robocalls?
E: Not solved, but will change P# soon.

The recent scam phone call episode really caught my attention. In the last 6 months, I went from getting one call a month to getting several a day. They are often from the same NPA/NXX as my phone, but are always fake credit companies or a company trying to get me to buy a warranty for my car.
Here is the fucked up thing, because of this podcast, I started calling the numbers back, and i was shocked to realize they are real numbers of unsuspecting people, not some robo-dialer. These assholes are spoofing random phone numbers of unsuspecting people to harass consumers.
Such assholes!
Anyway, has anything changed with federal enforcement of the do no call list, or consumer protections changed, or is this recent surge totally coincidental to our Presidents tenure?

Okay, so for background, the state of Washington just dropped 7-digit dialing across the state last month. This forced us to address the dial plan for one of our WA based customers, who has PRIs or POTS service at multiple sites.
Now, personally, I haven't used a POTS line in almost a decade, and when I did, I wasn't the one paying the bill. I and probably any other US millennial are just conditioned to dial a ten digit number and let the provider figure out the rest.
With the providers for this customer, they do charge long distance rates more than local, so we had to build a dial plan that wouldn't waste money.
We initially built a route that sends 10 digit calls out as-is if they are in the same area code as the DIDs at the site. If the area code was different, the system would prefix a 1 before sending.
What no one on my team realized was that the providers in Washington don't break down their rate centers by area code. They subdivide them at the exchange (NXX) level. This page shows all the different exchanges a subscriber in Tacoma, WA can dial. Note that the exchanges aren't contiguous, making wildcard patterns difficult.
Due to limitations in the scope of our support, I ended up redesigning the plan so that calls are only routed out locally if they match both the NPA and NXX of a DID assigned to the site. I know it's going to send out more calls as Long Distance, but at least it will stop the "You must dial a '1' before this number to complete your call" messages.
How have you guys handled this in the past? I think it's nuts that providers expect subscribers to remember down to the exchange level what is a local call versus long distance.

Sorry if this is a silly question. I have a table with phone numbers which are split like so:

NPA NXX LN 555 555 5555 ... 

The queries I use now (Oracle SQL) are either:

SELECT * FROM tns WHERE (NPA, NXX, LN) = (555,555,5555) 

or

SELECT * FROM tns WHERE NPA NXX LN = '55555555555' 

Is is possible to create a query that lets me use the full number (5555555555) without splitting it, but avoiding concatenating the columns (which is slow)?

How much ability do store sales reps have when choosing numbers in and NPA-NXX?
There is a number I would like for my business cellphone. It rings as not in service and shows in the database as the entire 1,000 block being assigned to the local att wireless switch.

Hi /excel,
I have a list of 10 digit phone numbers, that I am looking to get the rate centre for. I can get this list manually by going to http://localcallingguide.com/xmllocalprefix.php?npa=250&nxx=423 where NPA is the area code and NXX is the next three digits of the phone number. When I do this, it returns an xml. What I am looking for is a way to have the following as an input:

DID	NPA	NXX
2504235895	250	423

And the following output:

DID	NPA	NXX	RC	region	Exch
2504235895	250	423	Fernie	BC	015800

If anyone can point me in the right direction to solve this it would be appreciated.,
