How to Enter a Vietnam (+84) Number in Coinbase
Over 20% of failed international OTP deliveries happen because of duplicate country codes or unstripped domestic trunk prefixes. Follow the exact Vietnam (+84) formatting rules below when verifying Coinbase:
National Subscriber Digits Only
When you select 🇻🇳 Vietnam (+84) from Coinbase's country dropdown, paste only the subscriber digits above without repeating +84.
ITU-T E.164 Full String
If Coinbase or your API testing script asks for a single international E.164 phone string (Display format: +84 912 345 678), include the leading +84 prefix.
Domestic Trunk Prefix Policy
Strip the domestic leading trunk "0" when dialing internationally with +84 (e.g., domestic 0912... becomes +84 912345678).
Coinbase Pro Tip: Never use a temporary 10-minute phone number for a live Coinbase account holding real assets; always use a permanent phone number + hardware security key.
