  • MIN (Mobile Identification Number)

    The MIN (Mobile Identification Number) is a number that uniquely identifies a mobile telephone subscriber.

    MINs are 34-bits in length. The first 10 bits are sometimes known as MIN2, while the last 24 bits are referred to as MIN1. Together they are simply known as the MIN.

    In the United States, the MIN is derived from the 10 digital decimal telephone number assigned to the handset. For the telephone number (303)866-1010, the area code (“303”) becomes the 10 bit MIN2 and the local portion of the telephone number (“866-1010”) becomes the 24 bit MIN1.

    Internationally, MINs are calculated in a different fashion. The three digit mobile carrier identification number becomes MIN2 and the local portion of the telephone number becomes MIN1. IFAST, the International Forum on ANSI-41 Standards Technology, assigns the mobile carrier identification numbers. A MIN in this format is known as an IRM (International Roaming MIN).

    Unlike the IMEI, the MIN is not an attribute of the physical phone. The MIN is stored in a database that the cellular provider manages and can be changed at any time.

      what exactly does the MIN, that is in my settings, about phone and click on status, and from there it is directly below my phone number.. i am just wondering what is the purpose for this, and is it something I need to be concerned about? does it mean that my phone is being monitored or that it’s tapped? Thanks

      I too went to sprint they had no clue what it MIN means. Bought a stylos 2 and when i call the number under the MIN a lady answers. I did call from a landline blocked my number. My MIN number is same area code as i live in. So question is is this a clone thing or a used phone I paid new price for. thanks

      TYL that the MIN is always the same as the actual phone number, unless the number was ported to another company, in which case it will always be different.

      the sprint phone I got from ting has a MIN. When I called it, it was a fax machine. My other T-Mobile phone doesn’t have a MIN listed.

      Are there ways to test and see if your phone has been cloned?

      Many of the employees that work for Customs Border Protection have a lot to fear because they have extra marital affairs with women and in the process end up sleeping with their under age daughters, and they use the cloning technology to stalk them to make sure they live in fear and that they don’t report them to Department Of Justice.

      It includes gays in the American Intelligence Military, it all started when gay american soldiers sneaked military technology to stalk their gay military lovers in the National Guard, From there once the technology was out on the street it become widely available to technitians from the under ground world.

      That is how they do it, they stalk phone conversations, and when the
      person provides MIN number to phone service provider, the stalkers clone phone
      as if was their own.

      Yeah, my Virgin phone is the same, the MIN has the same area code (MIN2, I guess, unless you listen to Wikipedia, which says that part is the MIN1) but the rest of the number is different, although it has a prefix that is usually assigned to landlines in a neighborhood nearby. Didn’t try texting, but calling gave me the same generic voicemail box as any Virgin subscriber. Weird, but I doubt this is a security hole, a kludge, sure, but just an issue of rapid scaling in the cell industry. Bet it all gets standardized at some point. I mean, ten digit calling only holds, what, 10,000,000,000 numbers? And that’s the max, including numbers like (000) 000-0000. I bet we go to worldwide twelve- or fifteen-digit calling soon, and if we do, or something else changes things up, then you can bet all these loose systems will get consolidated into a more integrated, standardized protocol.

        It is a simple fix, like the Y2k “problem”. Still it has to do with old machines that can not handle a telephone number larger than the current allocated element field size. There should no longer be any step switches in use in th first world nations, so it is a matter of having their software updated to handle two or three more three digit fields.

        Off topic DB trivial:When I plotted out my first address book in software, I went all out allowing for growth in the various data elements. Numbers, names, no matter what, allow large data now.(I even have a ‘galaxy’ field).

      If the MIN is: (Mobile Identification Number) is simply the phone number of the cellular telephone……Then why do I have two different numbers? Can anyone explain this? My cellular number and the MIN are similar, both in Alabama and the number that is “NOT” mine is an active cellular number. How can this happen? Any advice would be much appreciated. Thanks

        Local Number Portability made MINs more confusing than before.  😀

        Where are you seeing two MINs?  Are you sure one isn’t a MDN or MSID?

          Jen is it a boost phone by chance? I just got boost and when I sent someone a text my number and a different number showed up. So I did some checking and found that number listed as my MIN. Is boost selling refurbs as ‘new’ phones? My mom also went with a boost phone and tech support told her it was a used phone when it just came out of the package. I’ve never had a phone hacked but this just seems like an open invitation.

        The MIN is not stored in the handset or in a SIM card.  It is stored in a database managed by the mobile telephone company.
