Step by step
Coinbase asks for your number at the phone step during sign-up or Settings → Security. Expect a numeric SMS code; it can arrive by SMS.
Get your Vietnam number
Sign up at PhoneBorn with an email, top up with crypto and choose Vietnam: a monthly plan ($3.22) if you want to keep the account, or a single-use Coinbase OTP number ($0.29) for one code.
Open Coinbase
Go to the phone step during sign-up or Settings → Security.
Enter the +84 number
Select Vietnam (+84) in the country picker and paste the number from your dashboard without a leading 0. Vietnam mobiles look like 09x xxx xxxx → +84 9x xxx xxxx.
Enter the SMS code from your inbox
Enter the SMS code from your inbox.
Follow the prompt
Add an authenticator app or security key as your main 2FA.
Day-to-day life in Vietnam runs on Zalo, Facebook and Messenger, yet Coinbase remains the app for a stable 2FA number for a crypto account. A +84 number keeps that account tied to the country without using your personal SIM.
Vietnamese diaspora: Vietnamese communities in the US, Australia, Japan and Europe keep a +84 number for family chats and MoMo payments.
Coinbase sends sign-in and recovery codes to the number on file.
Vietnam has its own messaging giant in Zalo, which sits alongside Facebook as the main way people talk. A fast-growing tech outsourcing sector and a large overseas diaspora both keep demand for +84 numbers strong.
Local context
Vietnamese SIM cards must be registered with a passport or national ID, and unverified subscriptions can be suspended. A Vietnam number from PhoneBorn needs no SIM and no ID — only an email.
