ESN Code Checks, Day by Day

Every ESN code check from the last 14 days, plotted by the day it ran. Green is how many came back working. Red is how many esn.com would not accept. That is the checkout testing you did not have to sit through yourself.

What These Numbers Mean

A code check is one result for one code. Most are our agents applying it to a real cart and reading the order total before and after; the rest come from tracked orders and from shoppers reporting back, as broken down above. Worked means the code was accepted and the total went down. Would not apply means esn.com refused it on that cart. That is not the same as the code being fake. The usual reasons are:

  • It expired or the store switched it off after it was published.
  • It was single-use and had already been redeemed.
  • It only covers certain categories, brands or individual products.
  • The cart did not reach a minimum spend.
  • It is limited to new customers, a first order, or an email sign-up.
  • It cannot be combined with an active sale or another code.
  • It is tied to a different country, currency or membership.

So a code that failed one check can still work on your cart, and the success rate (checks that worked divided by all checks) is best read as how easily ESN discounts apply in general, not as a verdict on any single code. Hover any bar in the chart to see that day on its own.

Locate the Code Box at esn.com

The agents tested the code. Entering it is the one part we leave to you. Here's exactly where the ESN promo code goes at checkout.

Follow the shopper-submitted screenshots below to spot the ESN promo box and apply your code. Miss a step and even a working code does nothing, so the agents mapped every one for you.

Before You Buy at ESN

What shoppers ask most about ESN.

›Can I combine multiple promotional voucher codes on a single order?

Only one voucher code can be redeemed per checkout transaction. Promotional codes cannot be stacked or applied retroactively to completed orders.

›Are there specific products or categories excluded from voucher code discounts?

Voucher codes generally do not apply to already marked-down bundle deals and specific limited-edition launch items unless stated otherwise in the promotion terms.

›What should I do if my newsletter welcome discount code is not accepted at checkout?

Ensure the code is entered exactly as received without extra spaces and that your cart meets any minimum purchase requirements specified in the welcome email.

›Does ESN offer retroactive price adjustments if an item goes on sale after purchase?

ESN does not offer partial refunds or price matching for items purchased before the launch of a promotional sale event.

How We Verify ESN Codes

Nothing goes up here on trust. A ESN code is collected, applied to a real esn.com cart, dated the last time it took money off an order, scored on what came back, and pulled once it stops clearing. Promotions have no code to run through a checkout, so those are dated when they go live and dropped when they lapse. Here is how far that has got on this page, and every change the agents logged along the way.

Help Other ESN Shoppers

Not every ESN code reaches us from the store. 14 codes on this page were first submitted by shoppers. Wherever a code comes from, it still has to pass the same cart test before it goes up here.

Have a code we missed?

Send it over and the agents will run it through a real esn.com cart. If it works, it lands here with the test behind it.

Did a code work for you?

Open any ESN code above and tell us whether it worked. It takes one tap, no sign-up, and a code that keeps failing gets pulled off the page.
