I want to create coupon codes that users can remember easily. My idea is something like:
- squirrel45
- nantucket23
That is, a real word chosen randomly from a long dictionary list (preferably compiled for this purpose) combined 2 random digits. My questions are:
- Where can I find such a dictionary list?
- Do you see any problems with the system? (security is not ultra important here, just something reasonable is fine)
- Can you suggest any good improvements or alternatives?
Fwiw I am not crazy about the Markov word generators because I think their idiosyncrasies would be too hard to remember. I’d like a client to be able to keep the code in his head, and tell it to the merchant when he arrives to redeem it.
Thanks,
Jonah
Word lists are easy to find. Make sure you sanity filter them for foul words 😉
Here’s a huge word list that can be easily scrubbed:

From there you can easily load in words into your database and create your coupon code like so:
After you do this, simply store your coupon code in the database and whenever you make a new code, check it against existing codes before you apply it. Even slim odds are possible odds.
