Because your account is only two months old, this number is likely a {"term": "vantage-score", "text": "VantageScore"} or a telecom-specific score.
“I moved to the US 6 months ago and got a Capital One credit card with a $500 limit 2 months ago, which was raised to $600. I recently applied for a phone on credit, and a soft check showed my credit score is 443. Is this normal for a new credit file, or is something negatively impacting my score?”
Summary
You have not ruined your US credit forever.
Next steps
Your credit file is too new for a standard FICO score, so the phone carrier saw a different model.
Understand the 6-month rule
A standard {"term": "fico-score", "text": "FICO Score"} requires six months of account activity to generate. Since your card is only two months old, the carrier likely saw a VantageScore, which can calculate within a month, or a specialized telecom industry report.
Check your official credit reports
Request your free credit reports from the major bureaus to see exactly what the phone carrier saw. Look for any errors reported by Capital One.
Pay down your credit card balance
To improve your score, pay down your revolving balance so you use less than 30 percent of your $600 limit. The lower your ratio, the more positively the scoring models respond.
Make all payments on time
Payment history is the biggest factor in your credit score. Set up automatic payments or reminders so you never miss a due date.
Legal sources
Here are the exact rules from credit bureaus and financial authorities that explain your score and how to fix it.
Experian
A VantageScore can generate in a month, while a FICO Score takes six months of history.
For example, a VantageScore ® ™ credit score can often be calculated within a month of the account appearing on the credit report, but some versions of the FICO ® Score Θ may require up to six months of account activity in order to generate a credit score.
Chase
Phone carriers may check specialized telecom reports instead of standard credit scores.
Additionally, carriers may also check specialized industry reports to review your payment history with mobile carriers.
The Credit People
Keeping your credit utilization below 30 percent helps improve your score.
Reduce credit-card utilization below 30 % of each limit; the lower the ratio, the more positively scoring models respond.
