How to generate unique (random) coupon codes?
Generating unique coupon codes - how to ensure good customer experience, personalization, fraud protection, tracking of coupon redemptions and ROI?
Generating random coupon codes (unique number series or number and letter series) will help you with 1:1 tracking, marketing personalization, influencer management, affiliate sales management and fraud prevention.
Let’s start with the most obvious - fraud protection - you clearly don’t want your vouchers to be easily forgeable. The key to generating hard-to-guess coupon codes is a large set of possible codes where only a small fraction of them is actually valid.
Customer Experience and Coupon Redemption
How to improve the customer experience with coupon redemptions?
Once you make your codes un-guessable, you should think about customer experience. First of all, keep in mind there’s a trade-off between codes security (particularly length) and ease of use for the end user. It’s you who decides how to compromise these issues in your business reality. There are, however, a few general tips that should cut down on customer complaints without substantial security trade-off or too much development effort:
- Don’t make it too long - Usually, an 8-12 characters string should be un-guessable and unique enough.
- Avoid ambiguous characters - It’s difficult to see the difference between O and 0 in the random string. I (upper case i) and l (lower case L) is even more tricky. We all recall the feelings when forced to try different combinations over and over again. So, you’d better prevent this before it hits your customer service team. Just exclude them from the character set.
- Cut the code into a few small parts, e.g. ABCD-1234-XYZ - It’s a subtle change but it simplifies typing at the checkout view. This adds up to the overall buying experience and customer satisfaction.
Learn how to generate, manage and track numerous coupon campaigns without worries about fraud. Voucherify free trial shows how to make unique promotions in minutes and our dedicated team is ready to help.
It’s often the case that you run different voucher campaigns at the same time. Once they’re finished, the marketing team asks you for the performance reports. How many vouchers have been redeemed, what’s the number of failed redemptions, how many new customers have been acquired and so on. To handle different campaigns separately and to help further data crunching, it’s reasonable to extend your codes with a proper prefix or suffix from the first campaign. For example: XMAS-ABCD-1234.
