EAN/UPC Code (also known as EAN 13, GTIN 13, GS1 Retail)

Obtaining bar code number(s)
Welcome to Terrapin Solutions Ltd.  If you need bar code number(s) for your product range, then you have come to the right place.

Prices start from as little as £20 for one bar code number.  There are no annual fees to be paid.  Unit discounts are applied for multiple numbers purchased.

The number(s) would be yours for life and you can use them to sell your products all around the world and also with online fulfilment houses such as Amazon.

With the £20, you automatically receive EPS (Encapsulated PostScript) and high resolution JPEG artwork files.

If you are not having packaging produced then we could supply pre-printed labels for you to affix directly to your product.  The labels are not included in the £20, but are not cost-prohibitive, click here for details.

General Information on the EAN Bar Code
EAN stands for European Article Numbering and it is based on the UPC (Universal Product Code), which is used in the USA and Canada to standardise article numbering. With only minor logical modifications in comparison to UPC, the EAN offers a bar code system that is compatible all over the world. The advantage offered by the EAN bar code is its high information density, its worldwide standardisation and the distribution of the numbers by national bodies. EAN is the industry standard for retail goods and is found on over 90% of food products.

The following four bar codes are used in trade applications:

  • EAN - European Article Numbering
  • IAN - International Article Number
  • JAN - Japanese Article Numbering
  • UPC - Universal Product Code

    There are two versions of EAN (EAN-8 and EAN-13) and five versions of UPC (A-E). The EAN, the JAN and the IAN have an identical structure, and are also identical to UPC, except for the number of digits.

    EAN-13 is really a superset of UPC-A, so any scanner capable of reading EAN-13 symbol will also be capable of reading a UPC-A symbol. The only difference between the two bar codes is that the number system code in UPC-A is a single digit (0 - 9) whereas an EAN-13 number system code is two digits ranging from 00 through 99, which is basically a country code. Every country has a numbering authority which assigns the manufacturer codes to companies within its jurisdiction.

    EAN is a fixed-length bar code and can be used to encode numeric-only data.

    The EAN Character Set is composed of:

  • 10 digits
  • 1 marginal signal
  • 1 delimiter

    The EAN symbol consists of parallel dark bars of different widths on a light background, completed by an optical character line in OCR-B print. The OCR print line is not intended for automatic reading. The principal characteristics of the EAN symbol are:

    • The symbol consists of two halves, each with 4 (EAN-8) or 6 (EAN-13) digits, as well as a marginal signal and a center signal (delimiter). The marginal signal and centre signal are slightly longer than the other bar code characters, and do not contain human readable OCR-B characters below them.
    • The reading stations are able to recognise each symbol in individual halves. Each symbol half is greater in height than in width.
    • Each data character (digits 0 to 9) is divided into 7 equal parts (modules); these are either dark (bars) or light (spaces). A data character contains two bars and two spaces, each with a width of 1, 2, 3 or 4 modules.
    • The size of the characters can be changed according to the laser printer matrix. It is very difficult to keep to the specified tolerances. A good reading result is often achieved when the reading device is prepared to accept deviations from accepted tolerance values.

    Structure of the 13-place EAN Symbol (EAN 13)

    The EAN-13 Symbol consists of (from right to left):

    • One marginal signal
    • Six even-parity characters (character Set C) in the right half. The character in the first position is the check digit, calculated using Modulo 10 with weighting 3 on the basis of the 2nd to 13th postitions. The characterse in positions 2 to 6 (5 utility characters) denote the individual article number of the manufacturer.
    • One delimiter (center signal)
    • Six data characters of varying parity (character sets A or B) in the left half. The two digits in positions 13 and 12 are reserved for the national sign, which is, like the manufacturer number (pos. 7 to 11) centrally distributed for Federal Republic of Germany by the CCG in Cologne. The 13th position is represented by a form of parity (change between character set A and B) of the digits in postions y to 12.
    • One marginal signal
    • Optical representation of the 13 positions of the EAN code in OCR-B type beneath the bar code symbols.

    Structure of the 8-place EAN Symbol (EAN 8)

    EAN-8 image

    The EAN-8 Symbol consists of (from right to left):

    • One marginal signal
    • Four even parity characters (character set C) in the right hal.The character in the first position is the check digit, calculated using Modulo 10 with weighting 3 from the 2nd to the 8th position.
    • One delimiter (center signal)
    • Four data characters of uneven parity (character set A) in the left half (pos. 5 to 8), positions 7 and 8 being reserved for the national symbol.
    • One marginal signal
    • Translation of the 8 digits of the EAN code into optically readable OCR-B1 pritn beneath the bar code symbol.

    The EAN bar code may also be supplemented by a special add-on code for books, newspapers, etc.

    Check Digit - Modulo 10 with weighting 3
    The Modulo 10 - check digit calculation, required for example for the EAN code, uses a weighting of 3, 1, 3 ...

    It starts with the rightmost data digit within a bar code symbol. This means that the check digit has the weighting 1.

    Note: the check digit is designated as Modulo 10, but is in fact a surplus to the number 10. Mathematically speaking, Modulo 10 is the remainder of the sum when the total is divided by 10.

    The following example shows the method of a Modulo 10 check digit calculation:

    Data Digit Sequence    0     6     1     2     8
    Weighting Factor    3x    1x    3x    1x    3x 
    Total (3x0)+(1x6)+(3x1)+(1x2)+(3x8)
    ----------------------------- = 3 remainder 5
                 10
    Check Digit 10 - 5 = 5
    Character sequence of bar code symbol Start 0 6 1 2 8 5 Stop
