Introduction

The Primary Account Number (PAN) is segmented by prefixes called "BIN", or Bank Identification Number.

The prefix size, also known as "BIN size", tells you how many digits on the left of the card number are used. Originally it was only 4 digits, today is 6 and is expected to reach 9 digits. The size is then parameterized as a range, reported in the binTable { sizeRange } query (see below).

Because the size of the BIN impacts the size of the card number (PAN), each BIN parameterizes the PAN sizes it expects, as well as a range in the BIN { panSizeRange } query.

Once the BIN is recognized, the system can be queried for several attributes, such as:

  • What is the country of origin of the card? BIN { country }

  • Can the card be used internationally? BIN { isInternational }

  • What is the financing of the card? credit, debit, multiple (both)? BIN { funding }

  • Is it a corporate or personal card? BIN { isCompany }

  • Is it a real or virtual card (CardToken)? BIN { isToken }

  • Where can I capture the card? (E.g ATM, Point of Sale, Internet ...) BIN { allowedCaptures }

  • What are the types of use? (Eg. Credit, Credit in installment by the Store, Debit...) BIN { usage }

  • Which is the card scheme? BIN { brand }

  • Which network can the card be used for? (Eg Elo, Elo-Discovery ...) BIN { cardNetwork }

  • What is the issuer (bank) of the card? BIN { issuer }

  • What cardholder services does the card offer? (Eg Travel Insurance) BIN { services }

Consulting a single BIN

A BIN can be queried with the bin(id) query:

query OneBin {
  bin(number: "509069") { # Banco do Brasil - Grafite

    # Should return Banco do Brasil
    issuer {
      name
    }

    # Should return Grafite
    product {
      name
    }

    # Captures allowed (e.g.: point of sale `POS`, Internet,
    # Telemarketing...)
    allowedCaptures {
      name
      code
    }

    # Uses allowed (e.g.: Sight Credit, Debit, In installment by
    # Store...)
    usages {
      name
      code
    }

    # Cardholder services (benefits) (i.e.: Travel Insurance,
    # Purchase Protection, Extended Warranty, Wi-Fi)
    services {
      name
    }
  }
}

Such parameters can be used by third parties users, for example a merchant, for card validation and even fraud prevention. However, querying a BIN at a time may not be efficient, since BINs do not change as often. It would be better to download a copy of the entire table.

Downloading the entire BIN Table

For this we use the ‘binTable’ query, which returns a list of all the BINs and each one can be queried in the same way that we used individually in the previous example:

query TableOfBins {
  binTable {
    # BIN size range (in digits)
    #
    # Indicates which BIN sizes are
    # present in the table, for
    # exemple `{ min: 6, max: 9 }` indicates that you should
    # check the
    # 


Card number (PAN) prefixes 
    of sizes 6, 7, 8 and 9.
    #
    # In case the values are
    # identical, only one size is supported,
    # for example `{ min: 6, max: 6 }`, only size 6 is
    # present.
    sizeRange {
      min
      max
    }

    # BINs in use (allocated).
    #
    # In this query we will
    # extract a lot of data as an example, if
    # not all are of interest to you, you can simply delete
    # the lines.
    #
    # If more information is
    # needed such as some subfield ‘ID’,
    # address of an Issuer or something similar, just include them
    # according to the fields
    # listed for each subtype.
    bins {
      # BIN Number
      #
      # The number of characters
      # defines the number of digits (size)
      # of the BIN.
      number

      # Range of card number sizes
      # (PAN).
      #
      #
      # The PAN (Primary Account
      # Number) number is 
      # usually 16-digit, being    


      # returned
      # as `min: 16, max: 16`. However, due to need for
      # more cards
      # available, the Market is
      # gradually migrating to more
      # digits -- it is expected to soon it will reach 19.
      #
      # When requesting and
      # validating user input, find a valid BIN
      # for the prefix and then check this field to
    # see if the number of digits is correct.
      panSizeRange {
        min
        max
      }

      # If the card is `CREDIT`, `DEBIT` ou `MULTIPLE` (both).
      funding

      # If the card allows
      # international or domestic use only
      isInternational

      # If the card is corporate or individual
      isCompany

      # If the card is virtual, that is, a _token_
      isToken

      # Card product, e.g.: Nanquim, Grafite, Viagem...
      product {
        name
      }

      # Allowed captures (i.e.: point
    # of sale `POS`, Internet,
      # Telemarketing...)
      allowedCaptures {
        name
        code
      }

      # Uses allowed (e.g.: Credit,
      # Debit, In installment by Store...)
      usages {
        name
        code
      }
    }
  }
}

However, these parameters are not often modified, usually once a week. For this we must write it down the last update and use it in the next query, if it has not been modified, nothing will be returned.

Queries



bin

Query BIN information for a given number

If the number is not associated with an allocated BIN, then it returns null.

Usually only used in tests or demonstrations since users download the entire table with binTable () and do local queries. Since the frequency of updates is low (1 time per week).

Argumentos:

number: String obrigatório

The BIN number, which in turn is a prefix of the card number (PAN - Primary Account Number), that is, the first digits are taken (on the left). The number of digits is parameterized in binTable {sizeRange}, for example {min: 6, max: 9} indicates that the system supports BIN of sizes 6, 7, 8 and 9.



binTable

Download the entire table if the table has been modified after a certain date or version.

ifModifiedSince and ifNoneMatch are equivalent to use in HTTP (If-Modified-Since to Last-Modified, If-None-Match to ETag) and can be used to search for updates in a single request.

In case ifModifiedSince and ifNoneMatch are specified and the table has not been changed, null is returned indicating that the table has not changed.

BIN

Represents a BIN (Bank Identification Number or Bank Identification Number) in the system.

The BIN is relative to the initial numbers of a card and identifies \in the issuer and associated products.

Each banner has tracks BINs reserved for their use, these are vailable as reserved in thebinTable query.

But the greatest interest is for BIN in use (allocated), which will load information about the sender (bank), financing (payment, debit or both), products (term payments, prepaid, Card for construction - Construcard ...) and even services such as insurance ninety or access to WiFi.

The BIN table is dynamic:

  • As cards from the same prefix (BIN) are unusable and run out of users, the BIN can then be recycled for a new use.

  • As new products are inserted, a previously reserved BIN without users will then be allocated, entering into use.

For i So it's important to keep the BIN table up to date, see binTable. To find out if the table has been updated use \in the name fields similar to HTTP lastModified (date and time the last modification) and etag (entity tag or label of think), which offers a unique identifier on the table , if he changeed then the table change as well.

The largest use of tokens is to reduce security problems, before a merchant or cardholder.

If true, then this BIN is used for tokens instead of physical (plastic) cards. Iffalse then this BIN is used for traditional, physical (plastic) cards.

BINTable

BIN Table.

Table of all BINs (Bank Identification Number) in the system, both allocated (bins) and reserved (reserved).

Table users are systems that often check\card numbers and their attributes, for example virtual stores (e-commerce).

The table has "version" (etag), as well as the date and time of the last modification, allowing the user to identify changes. In general, the tables are modified weekly.

Campos:

lastModified

:

DateTime

Date and time of last table change.

Can be used to identify that the table has changed. Either by making a query by date and time, either by doing binTable query and passing the date and time of the last known version -- if the table has not changed, nothing will be returned.


etag

:

String

Entity Tag (Entity Tag).

Similar to use in HTTP headers, ETag serves as an identifier that changes when the contents of the table changes.

Like lastModified, it can be used to identify changes in the table. Whether it is querying for the new etag, whether by querying binTable and passing the previous etag -- if the table has not changed, nothing will be returned.


sizeRange

:

IntRange obrigatório

Known BIN Sizes.

The range of sizes of the digit numbers that make up BINs. That is, when querying BINs don't should do with a fixed size (i.e: 6) but all sizes defined in this range.

In the past the BINs were only 4, today they are 6 digits, however the market is migrating to up to 9 digits in the next few years. Then use the number of digits parameterized in your code!

Example: sizeRange { min: 6, max: 9 } informs that you must get size prefixe 6, 7, 8 and 9 from the card number and then fetch them on the table.


bins

:

lista obrigatória de BIN obrigatório

Listing of BINs in use (allocated).


reserved

:

lista obrigatória de ReservedBIN obrigatório

List of reserved, but unused BINs.


binsRegexp

:

String obrigatório

Regular expression that identifies BINs in use (allocated).

The regular expression returned will identify the BIN (number) and the number of digits relative to the panSizeRange of each entry.

For user convenience of regular expression, a group will be returned to the found BIN. The group number is undefined because several are used and built automatically. However one and only one group is returned on success. See the examples below for more details.

For example, consider a BIN table with only two inputs in use (allocated):

  • number: "509069" with panSizeRange: { min: 16, max: 16 };

  • number: "12345678" with panSizeRange: { min: 17, max: 19}.

The regular expression will be: ^(?:(12345678)\d{9,11}|(509069)\d{10})$. If you identify BIN 12345678, for example the 12345678123456789 card, then group 1 will be returned with the value 12345678 (BIN). If you identify BIN 509069, for example the 5090691234567890 card, then group 2 will be returned with the value 509069 (BIN). If another BIN is passed, or the number of digits of a card does not match the panSizeRange of the BIN, then no group is returned and the regular expression will find nothing.


reservedRegexp

:

String obrigatório

Regular Expression that identifies reserved but unused BINs.

The regular expression returned will identify the BIN (number) and the number of digits relative to the panSizeRange of each entry.

For user convenience of regular expression, a group will be returned to the BIN found. The group number is undefined because several are used and built automatically. However one and only one group is returned on success. See the examples below for more details.

For example, consider a BIN table with only two reserved (unused) entries:

  • number: "509069" with panSizeRange: { min: 16, max: 16 };

  • number: "12345678" with panSizeRange: { min: 17, max: 19}.

The regular expression will be: ^(?:(12345678)\d{9,11}|(509069)\d{10})$. If you identify BIN 12345678, for example the 12345678123456789 card, then group 1 will be returned with the value 12345678 (BIN). If you identify BIN 509069, for example the 5090691234567890 card, then group 2 will be returned with the value 509069 (BIN). If another BIN is passed, or the number of digits of a card does not match the panSizeRange of the BIN, then no group is returned and the regular expression will find nothing.


allBinsRegexp

:

String obrigatório

Regular expression that identifies all BINs (allocated and reserved).

The regular expression returned will identify the BIN (number) and the number of digits relative to the panSizeRange of each entry.

For user convenience of regular expression, a group will be returned to the found BIN. The group number is undefined because several are used and built automatically. However one and only one group is returned on success. See the examples below for more details.

For example, consider a BIN table with only two reserved (unused) entries:

  • number: "509069" with panSizeRange: { min: 16, max: 16 };

  • number: "12345678" with panSizeRange: { min: 17, max: 19}.

The regular expression will be: ^(?:(12345678)\d{9,11}|(509069)\d{10})$. If you identify the BIN 12345678, for example the 12345678123456789 card, then group 1 will be returned with the value 12345678 (BIN). If you identify BIN 509069, for example the 5090691234567890 card, then group 2 will be returned with the value 509069 (BIN). If another BIN is passed, or the number of digits of a card does not match the panSizeRange of the BIN, then no group is returned and the regular expression will find nothing.
