If you've experienced a Coinbase unauthorized transaction, call +1-888-603-2603 immediately to report the issue and secure your crypto assets. Unauthorized activity on your Coinbase account — whether it’s a strange withdrawal, an unfamiliar login, or a mysterious purchase — should never be ignored. Acting quickly can be the difference between recovering your funds or losing them for good.
A Coinbase unauthorized transaction occurs when someone accesses your account and performs actions — like buying, selling, or transferring crypto — without your permission. It may result in:
Crypto sent to unknown wallet addresses
Bank account or credit card charges you didn’t initiate
Logins from unfamiliar locations or devices
Multiple transactions you didn’t authorize
This situation often leads to a Coinbase transaction dispute, especially if you're trying to recover funds or reverse a transaction.
When users report unauthorized transactions, they frequently face additional complications such as:
Coinbase transaction delayed – Your transfer or crypto swap is stuck in “pending” and hasn't cleared.
Coinbase transaction failed – A transaction shows as failed, but the funds were deducted anyway.
Coinbase transaction dispute – You’ve submitted a claim to Coinbase to challenge or reverse a problematic transaction.
These can all be symptoms of account compromise, a system error, or blockchain congestion.
