Why This Address Is On Your Credit Report
This is where most people get stressed. You pull your annual credit report and see an inquiry from an entity you don’t recognize, and the address listed is Box 903 San Antonio TX.
Don't freak out.
When you apply for credit at a store, the store doesn't usually lend you the money. They partner with a bank. Citibank (Citi Retail Services) is one of the biggest players in this space. They manage the private label credit cards for dozens of brands. If you applied for a card to get 10% off a new fridge, the bank "pulled" your credit. Because the processing center is in San Antonio, that’s the geographic location that gets logged on your report.

How to Handle Mail From This Address

On the flip side, it might be your actual new credit card. Many replacement cards or PIN numbers are sent from regional hubs in Texas to ensure they are centrally located for national distribution.
What if it's a scam?
Let’s be real—scammers know that people recognize this address. There have been instances of "phishing" mailers that use a San Antonio return address to look official. They want you to call a number and give up your Social Security number.
Here is the rule: If the letter asks you to call a number that isn't on the back of your official credit card or a verified bank website, be skeptical. If you’re worried, don't call the number in the letter. Call the Citibank customer service line found on their official site and ask if they sent you mail from the San Antonio hub.
