Click the Get Preview button to see what your codes will look like with the current settings.

Allowable Characters

---

This setting allows you to decide which characters can be included within the codes that are generated. You can include the characters A-Z, a-z and 0-9, and the following symbols:

- ! $ % & * _ + = @ # . ?

You can specify between 2 and 80 different characters which can be used in your codes. Remember to only include characters that are suitable for the type of code you want and which are not ambiguous. For example, you may not want to include the letters 'I' or 'O' as they look similar to the numbers 1 and 0.

If you enter duplicate characters, they will be automatically stripped out.

Code Length

---

This setting determines how many characters each code will contain, excluding any formatting or padding characters you might apply.

Depending on your subscription level, you can generate codes containing up to 24 characters. The minimum number of characters a code can contain is 4.

Number of Codes

---

This setting tells us how many unique codes you want to generate. Each and every code will be unique within the batch generated, however if you generate subsequent batches, they may contain codes generated in previous runs.

The number of codes you can generate in a batch depends on your subscription level, up to a maximum of 10 million.

Random Output

---

By default, the codes will be generated in a sequential order (e.g. alphabetically, or numerically). By checking this box you tell the Code Generator that you want the codes generated in a random order.

Pick Sub-Set

---

You may want to extract a sub-set of the generated codes. Using this setting you can specify how many of the generated codes will be randomly selected and saved to a seperate file.

This sub-set of codes could, for example, be the winning codes in a redemption campaign.

Code Pattern

---

You can determine how the codes are formatted by specifying a pattern here. Use the ~ (tilde) character to represent each of the characters that appears in the generated code.

For example, if you want an 8-digit code represented as two groups of four separated by a space then the pattern would be:
~~~~ ~~~~

If you wanted each code prefixed with the letters XY then the pattern would be:
XY ~~~~ ~~~~

Range Definition

---

You may want to generate a set of code only between a specific range. The number of characters for both the lower and upper ranges must be same as the number of characters in the generated code.

For example, you may want to generate 4 character alphanumeric codes starting at "DDDD" and ending at "GGGG", and so these would be the From and To ranges respectively.

You could also generate a random selection of numbers having 5-digit numeric-only codes and specifying the range "10000" and "50000" to give you only codes between those two numbers.

This is a powerful feature, and combined with the Code Pattern you have great flexibility and sophistication.

Excluded Strings File

---

You can upload a file from your computer which contains a list of words or sub-strings that shouldn't appear in the codes that are generated.

For example, you may want to exclude competitors' brand names or trademarks from your redemption codes, or you may have a list of profanities which should be excluded. (Note that a database of English profanities are already automatically excluded from appearing within the codes).

The file should be a plain text file, with one word or sub-string on each line, followed by a carriage return.

The maximum file size is about 2Mb - if you attempt to upload a file greater than this size then the server may generate an error.
