Open Coinbase
Go to the phone step during sign-up or Settings → Security.
Enter the +1 number
Select United States (+1) in Coinbase's country picker, then paste the digits your dashboard shows after +1 into Coinbase.
Enter the Coinbase code
Coinbase sends a numeric SMS code by SMS. SMS codes appear in your PhoneBorn dashboard next to the +1 number; type the code into Coinbase to finish.

E-commerce sellers: Sellers on Amazon, Etsy and eBay targeting US buyers use a local number for customer support and account verification.
Coinbase sends sign-in and recovery codes to the number on file.
