Coinbase sends sign-in and recovery codes to the number on file.
Grenada, the Spice Isle, has an unusually international population for its size thanks to St. George’s University and its medical school. Yacht crews sheltering from hurricanes and applicants to its citizenship programme add to the mix. A 473 number helps all of them fit in with how the island communicates.
Local context
Grenada is on the +1 numbering plan with area code 473, so local numbers are familiar to North American apps and contacts. A Grenada number from PhoneBorn needs no SIM and no ID — only an email.
