Cryptocurrency transactions are irreversible, if you send cryptocurrency to a third party, you cannot reverse it or stop payment. When you send cryptocurrency to a blockchain address, you must be certain of the legitimacy of any involved third-party services and merchants, and only send cryptocurrency to entities you trust.
Pro tip: If it sounds too good to be true, it probably is.
Technical Support and Impersonation Scams
Fraudsters set up scam customer support phone lines and impersonate a variety of companies—including Coinbase—in the finance, tech, retail, telecom, and service industries. These scam phone numbers are spammed on the internet, luring unsuspecting victims seeking assistance. The scammers may also conduct outbound calls directly to potential victims. These scammers are skilled in social engineering, making false claims to deceive and manipulate their target into providing personal information that will be used for fraudulent purposes.
Never give support staff (or anyone else for that matter) remote access to your machine. This effectively gives the scammer full access to your computer, online financial accounts, and digital life.
Never give out your 2FA (2-Factor Authentication) security codes or passwords. Coinbase staff will never ask you to share sensitive authentication credentials.
Never accept outbound calls asking for your confidential personal information. Be aware that scammers can spoof legitimate phone numbers when conducting outbound calls.
Only contact Coinbase via the phone number listed on https://help.coinbase.com/ or via email on https://help.coinbase.com/contact-us
Never send cryptocurrency to external addresses on behalf of alleged support agents. Coinbase staff will never ask you to send cryptocurrency to external addresses.
Giveaway Scams
Scammers are using social media to perpetuate giveaway scams. They post screenshots of forged messages from companies and executives promoting a giveaway with hyperlinks to fraudulent websites. Fake accounts will then respond to these posts affirming the scam as legitimate. The fraudulent websites will then ask that you “verify” your address by sending cryptocurrency to the scam giveaway.
Learning rewards is a legitimate method for earning cryptocurrency and any giveaways that Coinbase offers will direct you to Coinbase.com. Coinbase will never ask you to send crypto to an address in order to receive crypto back.
Never send cryptocurrency to giveaways under the guise of address verification.
Be skeptical of all giveaways and offers found on social media. Do not trust screenshots in reply messages as images can be forged and altered.
Use your favorite search engine to do research on any entity soliciting you on social media. If the offer sounds too good to be true, it probably is.
Check the giveaway URL to make sure it directs you to Coinbase.com.
Report any phishing attempts or scams.
Coinbase’s legitimate social media profiles are listed in this help article. Any other profiles should be considered fraudulent.
Investment Scams
These scammers ask you to invest money to earn higher returns without financial risk, then request you to bring more people in to do the same. They often need a constant flow of new people investing in order to make money. Ponzi and pyramid schemes are great examples of investment scams.
For the US, if you come across one of these scams, contact the Securities and Exchange Commission, the Federal Trade Commission, or your state's securities regulator to get help. For the UK, contact the Financial Conduct Authority.
Tips for avoiding investment scams:
Be skeptical of websites or services promising high returns or unrealistic investment opportunities. If it sounds too good to be true, it usually is.
Only send cryptocurrency to trusted third parties. Search for publicly verifiable reviews or articles involving the recipient.
Watch for grammatical errors in communications or on websites. Scammers often make grammar or spelling mistakes.
Research the organization thoroughly. Check consumer-protection websites and make telephone calls and send emails to verify authenticity.
Extortion Scams
Scammers will often use information sourced from data breaches at other websites to trick you into thinking that they have more information about you than they actually do. For example, they might show you an old password that you may have used to affirm that their scam is legitimate.
If you are victim of an extortion scam, please immediately take these actions:
Report the email as spam to your email provider.
Run a precautionary malware scan on your computer using a reputable tool like Malwarebytes.
If you recognize any passwords included in the extortion email as one you currently use, change it immediately across all websites.
Contact your local authorities and file a police report. Have the authorities contact Coinbase directly. Coinbase is committed to full cooperation in all law-enforcement investigations.
While these messages can be alarming, they are almost always fraudulent. For steps you can take to make your account more secure, please see this help page.
Loader or Load-up Scams
Fraudsters frequently offer “loading” services on a variety of platforms. They claim to need Coinbase accounts with high limits, offering the victim a portion of the proceeds. These scammers use stolen credit cards on compromised accounts to perpetuate payment fraud. The end result is the victim is left with payment delinquencies after the legitimate card holder discovers the fraud, the scammer often steals any available cryptocurrencies and submits unauthorized charges on verified payment methods. Be aware, you are responsible for any payments submitted using your authentication credentials.
Never provide your passwords or security codes to third parties under any circumstances.
Report any “loaders” to Coinbase and to the platform where they are advertising their credit card fraud.
Telegram Scams
Coinbase has no official presence on the Telegram messaging platform. All varieties of scams can be found on this platform that target Coinbase users, including fraudulent payment bots and giveaway scams.

Employment Scams
Scammers will impersonate recruiters with fake job offers, actively seeking job hunters to steal cryptocurrency and personal information. Most frequently, the scammers will reach out to individuals who have posted their resumes online, and ask for payment to begin training. These "job offers" often include convincing offer letters and they may ask for confidential personal information.

Phishing
Phishing sites are malicious websites which mimic an authentic site in order to trick visitors into entering their login credentials or other sensitive information. These fraudulent websites are distributed through a variety of methods including email, SMS text messages, social media, and search-engine advertisements.
One of the best ways to avoid phishing sites is to always make sure you're accessing https://www.coinbase.com directly. Phishers will often use URLs like www.c01nbase.com to conduct these scams. Detailed information on phishing can be found in this help article.
Report Phishing to Your Mobile Provider
If you use a US-based cell phone carrier like AT&T, Verizon, Sprint, or T-Mobile, you can help reduce phishing attacks by sending the contents of suspicious SMS messages to 7726 (SPAM). This service is free, and allows mobile carriers to detect and block malicious messages on their network.
