Frequently Asked Questions
How long should coupon codes be?
6-10 characters is ideal. Shorter codes are easier to type but have fewer combinations. Longer codes are more secure against guessing. Use prefixes for campaign tracking.
Should I use letters, numbers, or both?
Alphanumeric codes (letters + numbers) offer more combinations. Exclude confusing characters like 0/O and 1/l/I. Some prefer letters-only for easier verbal sharing.
How do I prevent code sharing/abuse?
Implement single-use codes, tie codes to accounts, set usage limits, and track redemption patterns in your backend. This generator creates codes; validation is server-side.
