Yes. To verify a SNKRDUNK account at signup, you need a Japanese mobile number that can receive an SMS code. The platform sends a one-time code by text, and you can't finish registration without entering it. This is the step that stops a lot of international buyers before they ever place an order.
The good news: it's just one step, and it's solvable. This page explains what happens at signup, why a Japanese number comes up, and how buyers outside Japan get verified.
What is SNKRDUNK?
SNKRDUNK is a Japanese marketplace for sneakers, trading cards, and collectibles. International buyers often use it to find Pokemon cards, One Piece TCG products, limited-edition sneakers, and Japan-exclusive items that are hard to get elsewhere.
What happens at signup
When you create a SNKRDUNK account, the signup flow asks for a phone number and sends a confirmation code by SMS. To complete this step, you need a Japanese mobile number that can receive that code.
In practice, two things matter:
- The number is Japanese. International users commonly report that numbers from outside Japan don't get through this step.
- The number can receive an SMS code. No code received, no verified account.
After SMS verification, you can use the account normally for browsing and buying.
Why a Japanese number comes up
SNKRDUNK is based in Japan, and like most Japanese marketplaces it ties accounts to a local mobile number. From a user's point of view, this tends to come down to a few things:
- Region confirmation — it points to an account operating within Japan's market.
- One account per number — SMS verification limits duplicate and throwaway accounts.
- Fraud reduction — a real mobile number is harder to fake than an email address.
This isn't unique to SNKRDUNK. Mercari, Rakuten, and most major Japanese marketplaces work the same way. It's simply how account trust tends to work in Japan.
Will a VoIP or virtual number work?
Often not. International users frequently report that free VoIP or virtual numbers don't get through SNKRDUNK's signup verification, and that accounts built on throwaway numbers tend to be the least stable over time.
If you want an account that verifies smoothly and stays stable, the most reliable option people point to is a real Japanese mobile number — not a recycled internet number.
