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 Cambodia number
Sign up at PhoneBorn with an email, top up with crypto and choose Cambodia: a monthly plan ($3.98) if you want to keep the account, or a single-use Coinbase OTP number ($0.84) for one code.
Open Coinbase
Go to the phone step during sign-up or Settings → Security.
Enter the +855 number
Select Cambodia (+855) in the country picker and paste the number from your dashboard without a leading 0. Cambodia mobiles look like 012 xxx xxx → +855 12 xxx xxx (8–9 digits after 0).
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 Cambodia runs on Telegram, Facebook and Messenger, yet Coinbase remains the app for a stable 2FA number for a crypto account. A +855 number keeps that account tied to the country without using your personal SIM.
NGO and development staff: Cambodia hosts many international NGOs, and their staff use local numbers to coordinate with partners in the provinces.
Coinbase sends sign-in and recovery codes to the number on file.
Unlike most of its neighbours, Cambodia does much of its business on Telegram, from government notices to supplier chats. The US dollar circulates widely alongside the riel, and a steady stream of tourists and NGO workers need a local number to get things done.
Local context
Cambodian SIM cards must be registered with a passport or national ID at the point of sale. A Cambodia number from PhoneBorn needs no SIM and no ID — only an email.
