Mercari Code Checks, Day by Day

Every Mercari code check from the last 14 days, plotted by the day it ran. Green is how many came back working. Red is how many mercari.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 mercari.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 Mercari 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.

When Mercari Runs Sales

Recurring events worth timing an order around. Windows shift year to year, so treat them as a shopping calendar rather than a fixed date.

  1. late November
    Black Friday Savings

    Featured marketplace promotions and seller-driven discounts roll out across popular electronics, fashion, and home goods categories during Thanksgiving week.

  2. early January
    New Year Clear-Out

    Sellers across the platform slash prices on winter apparel and holiday inventory to clear out stock for the upcoming spring season.

  3. mid-July
    Summer Flash Sales

    Special promotional events offer reduced shipping rates and marketplace voucher drops to stimulate mid-summer peer-to-peer trading volume.

Before You Buy at Mercari

What shoppers ask most about Mercari.

›Can multiple coupon codes be applied to a single Mercari order?

Only one coupon or promotion code can be applied per transaction at checkout, and codes cannot be stacked together. Promotional credits apply automatically to eligible item prices before payment processing fees.

›Are there specific items or categories excluded from promotional codes?

Mercari platform-wide coupons typically exclude restricted goods such as digital gift cards, select regulated products, and prohibited items. Individual sellers may also specify unique conditions where platform coupons do not apply.

›Does Mercari offer retroactive price adjustments after purchase?

Price adjustments are not supported after an order has been completed or checked out. Buyers must negotiate offers or apply active promotion codes prior to final submission on the payment screen.

›What happens if a package shipped via Mercari prepaid labels is lost in transit?

Orders utilizing official Mercari prepaid labels include up to $200 in Shipping Protection for standard packages. Sellers must adhere strictly to tracking requirements and drop-off guidelines to qualify for carrier claim payouts.

How We Verify Mercari Codes

Nothing goes up here on trust. A Mercari code is collected, applied to a real mercari.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.

The agents keep retesting every Mercari code on this page. No one here vouches for a code they did not watch work. If one slips through expired, take the next on the list. We keep backups.

Help Other Mercari Shoppers

Not every Mercari code reaches us from the store. 1 code on this page was first submitted by a shopper. 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 mercari.com cart. If it works, it lands here with the test behind it.

Did a code work for you?

Open any Mercari 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.
