Receive SMS Codes from Coinbase with Japan Numbers
Last message:
100% Free No Sign-Up
Coinbase is tier one and their filters are brutal. Japanese SoftBank and German Deutsche Telekom numbers have a small window of success. I have gotten past the SMS step a few times for interface testing, but full KYC is never possible with a temp number.

Coinbase Verification Japan Numbers: Tier One Exchange Testing (30% Success)
Coinbase is one of the hardest platforms I have ever tested, but Japanese numbers from SoftBank have worked for me twice out of maybe seven attempts. +81 codes carry genuine weight because Japan is a major financial market, and Coinbase cannot afford to block legitimate Japanese users.
The setup has to be perfect. SoftBank number, brand new, zero crypto history, Japanese IP address, browser language set to Japanese, device that has never run a crypto app before. Even then it mostly fails. I only mention this because if you absolutely need to test Coinbase's onboarding, Japan is the least bad option I have found.
- Only SoftBank numbers with absolutely no history
- Japanese IP and full Japanese locale settings
- Success rate is low – two out of seven for me
- Never attempt KYC with a temp number
