Why do you need a phone number in CR and BG?
1. Many services, especially banks and verification services, during registration turn to credit bureaus and internal databases to clarify the compliance of the entered data. If the number you specified is not available anywhere, then your chances of verification are significantly reduced.
2. Most services do not work with VOIP numbers.
I register real USA numbers with addition to CR and BG.
After a short waiting period, the services will consider that the number really belongs to the person and verification will become easier.
