These types of payments don’t build credit
It’s very logical. Unfortunately, you need to use credit in order to build a credit history. Stuff like rent utility bills, gym memberships, checking accounts, saving accounts, cell phones are not extensions of credit and do nothing to build credit score.
These types of payments do not go on your credit report. Since credit scores are based on the information that’s on your credit report, this explains why you don’t have a score.
You nee to use credit in order to build credit history and have a credit score. For this you need to use either Installment credit (Student loan, Car loan, Furniture loan or any other loan) or Revolving credit (Credit Cards) and use them for at least 6 months.
