One Coinbase code on a +84 number costs $0.29 — the 2nd cheapest of 32 countries in Asia. Full Coinbase walkthrough and troubleshooting: Coinbase verification guide.
Get your Vietnam number
Sign up with an email, top up with USDT or USDC and pick Vietnam: a plan to keep the +84 number, or a single-use Coinbase OTP number ($0.29).
Open Coinbase
Go to the phone step during sign-up or Settings → Security.
Enter the +84 number
Select Vietnam (+84) in Coinbase's country picker, then paste the digits your dashboard shows after +84 into Coinbase.
Enter the Coinbase code
Coinbase sends a numeric SMS code by SMS. SMS codes appear in your PhoneBorn dashboard next to the +84 number; type the code into Coinbase to finish.
Tips for Vietnam numbers
- After +84, Vietnam mobile numbers begin with 3, 5, 7, 8, 9 — a quick check that you pasted the whole number.
- Only need one code and the country doesn't matter? Malaysia costs $0.26 for Coinbase, against $0.29 here.
- Coinbase requires identity verification; the phone number does not replace it.
Why use a Vietnam number for Coinbase?
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.
