If Google tells you that “This phone number cannot be used for verification” The “This phone number has already been used too many times for verification” when confirming an account, you can use the same number in countries that added an extra number for cell phone calls from abroad, and then they made it optional (but they did not remove it). In Argentina, you can add a 1 to the area code, then dialing + 54221xxxxxxx instead of + 5422xxxxxxx. In Mexico, add a 1 to the country code, putting + 521xxxxxxxxxx instead of + 52xxxxxxxxxx. (country codes are optional if you select it from the list).
