How to verify Coinbase with a Singapore number

Get your Singapore number
Sign up with an email, top up with USDT or USDC and pick Singapore: a plan to keep the +65 number, or a single-use Coinbase OTP number ($2.25).
Open Coinbase
Go to the phone step during sign-up or Settings → Security.
Enter the +65 number
Select Singapore (+65) in Coinbase's country picker, then paste the digits your dashboard shows after +65 into Coinbase.
Enter the Coinbase code
Coinbase sends a numeric SMS code by SMS. SMS codes appear in your PhoneBorn dashboard next to the +65 number; type the code into Coinbase to finish.
Tips for Singapore numbers
- After +65, Singapore mobile numbers begin with 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 $2.25 here.
- Coinbase requires identity verification; the phone number does not replace it.
Why use a Singapore number for Coinbase?
Day-to-day life in Singapore runs on WhatsApp, Telegram and Grab, yet Coinbase remains the app for a stable 2FA number for a crypto account. A +65 number keeps that account tied to the country without using your personal SIM.
