The character limit is very high. The system allows for up to 10,000 codes of 10 characters each; if you require a higher number than this, please contact the Easypromos sales department.
There is no problem with using codes of fewer or greater than 10 characters. 10 is only an approximation.
There is also the chance to activate the “Repeat codes” box in the “Coupons and promotional codes” section of the promotion editing form. Activating this option ensures that if more users enter the promotion than there are codes, the same codes will be reassigned, starting with the first code.This option is only available with the Premium and White Label versions of Easypromos.
