Display Name = "V" + sequence of digits

I don't know if something like this has already been posted...

I have been receiving a ton of calls lately (from a handful of different phone numbers) where the Display Name keeps changing.  For example, I have received 10 calls from 204-289-1756 in the past 5 days and the display name has never been the same twice.

In many cases the display name shows as the letter "V" plus a sequence of digits.  For example, my call display might show something like the following:

Name:  V40718441800268
Number:  1-204-289-1755
Date/Time:  4:44 PM Apr. 7

I found a post by another user who suggested that the first 3 digits after the V are the date, based on his observations.  He then suggested that the remaining digits were the real phone number that the call was coming from.

So in this example, "V40718441800269" expands out to
Date = 407 & phone number = 1-844-180-0269
I agree with the date part, but I think the rest of his explanation is wrong.

Instead, I offer THIS interpretation of the sequence of digits.

If # digits after the V is 13:
- Digits 1-3 are the date (in m/dd format, where the month is 1-9 for January-September)
->  In my example "407" = 04/07 or April 7th
- Digits 4-9 are the time in 24-hour format, based on the Eastern time zone.
->  In my example, 184418 = 18:44:18 or 6:44:18 PM (Eastern Time)
- Digits 10-13 are a "campaign number"
->  I suggest that this is the particular type of robocall (yes, it's probably a robocall) that's being dialed out.
->  In my example, the campaign number is #0268.

If # of digits after the V is 14:
- Digits 1-4 are the date (months = 10-12, for October-December)
- Digits 5-10 are the time
- Digits 11-14 are the campaign number

So when I compare the time on my call display to the "decoded V number", this is what I get:
Display Date = April 7; this MATCHES the Decoded Date (4/07)
Display Time = 4:44 PM (or 16:44 in 24 hour format; I am in Mountain time zone)
Decoded Time = 18:44:18 (Eastern time zone)

Add 2 hours to convert Mountain time to Eastern time and the Time matches also.

Well anyway, I hope others might find this useful.

With regard to the last 4 digits, I have seen that they are usually unvarying from one call to the next.  That is why I suggest that they are associated with a particular TYPE of call that's being dialed out.

Somebody got into details about the technology behind this.

FLR, thanks. I just got one of the "V" calls and found your post.

I accidentally answered it, a carpet cleaning robocall. Had a CID of V418141351000027032 (19 digits). Any CID like this is invariably, in my experience, a robocall and I don't answer them.

In this call the date and time check but the time was in my local Pacific time zone, not eastern, so maybe it's the local time of the caller that is in those digits. The rest of the numbers are who knows what.

Bark - thanks for letting me know.  I think you may be right in that it's the local time in whatever time zone where the call is originating from.  I guess I'm only getting calls from the Eastern Time Zone even though the caller pretends to be in the Central (area code 204 in my example).  I am so unhappy with the telcos - they should be able to filter out callers who continually change their call display information.  I don't think the telcos even care.

This method is no longer accurate. The first few digits no longer represent the date

Received a "V" call yesterday, actually, after hours.  

It showed as:  V10617225400011
Date: 11/06/2013
Time: 5:22PM

Not daring to call the number back attached, but it is going on our wall of numbers never to answer.

I got a call from V11514300103092 on the caller I.D. (Jan 15 @ 2:30pm local time) I googled the attached phone #951-285-0488 and it says it is a screen printing business in Colton, CA...why the heck would this type of business be robo-calling? I didn't answer but I'm tempted to, just to see if the call actually has anything to do with screen printing. Wondering if it's possible for crooks to hijack legit numbers for their own use without the owners knowing?

Yes, they can put any number they want in there. Do a google search with a one in front of the number and it will probably come back as an Indian, Pakistani, or Cyprisian number (or assorted other call centers in that area) On Google Earth you can do a search for Call Centers in India and they're all clustered around certain areas, mostly border areas near Cyprus. I have waaaay too much time on my hands sometimes.

It's either Elsinore, CA or

Indian Mobile Directory with Numbers starting with 9512850 ...

Mobile Numbers starting with 9512850-Trace any Indian Mobile Location, Locate service Provider, state/circle, signaling and other information.

I found that if you allow the caller to leave the number don't answer, just do a redial and call them back.  You will get a message that must legally identify the caller's business (usually looking for $).  The message will ask if you're not interested in contributing, you can opt out by hitting (whatever number they state) and your number will be removed from the list within a certain period of time!  

Until the FCC comes up with another solution concerning this very frustrating infringement on our privacy, this is all that is available for now.

Welcome to the world of technology!!!

In the last 3days i have received calls starting with a v.  6 in all and if I pick it up nobody is there or  I get a busy signal.  Today I decided to call them back after checking how many times they had called.  6 times and all different numbers. When reading your comments I can see the date is first.

I forgot to mention that when I called, the machine said your call is important to us, please wait for the next available agent.  Hung up after four minutes.  They never said the company's name.

I believe all V caller ids always begin with “V1” and not just”V.”
The date appears next like 3011 = Nov 30
The time is next: 1108 = 11:08 am or just military time.
Haven’t figured out the rest but it is like no originating phone number as the purpose is for the calling slime to hide their identity. It would take an actual analytic Court-ordered investigation to find identity. My guess is that lots of these calls are zombie (old, dead) debt collectors who make every attempt to conceal their identity to avoid being sued for millions  like both Portfolio Recovery Services and  Midland Credit have.

That's just because you're looking at calls from November (last digit '1'), which is why they are V1.   FLR's description match all mine across multiple months. I've gone through the ones in my CDR of my switch, and they all match this pattern. As noted, the "Hour" may be different, but is consistent with a timezone shift based on the calling party.

Also, when looking at the same numbers across over time, they almost always have the same remaining digits, which lends credence to the "Campaign ID" notion.  I do have one that changed, but I'll have to go over the phone recordings in order to confirm if it sounds like a campaign change.

Just speculating here: So why have a campaign identifier in the CNAM? CNAM could just be generated CNAM data for those people that make a little bit from the CNAM dipping, and could be used by the CNAM database provider to help identify who gets the kickback of the CNAM dip fees from the telemarketing campaign.  Their logs would show the data/time of the call, the remaining digits could be a affiliate/client id.  Otherwise, I don't see any reason why it's so clearly consistent across dozens of calls in my database, but there's clearly a pattern.

If this is true, then that might give the FTC something to ask (I mean subpoena) the CNAM provider for information about who owns, and profits, by the designated campaign.  So maybe including that full Vxxxxxxxxx string to the FTC would be good to do.
