How to Build Credit from Scratch: A Complete 2026 Guide
By Wealthvieu · Updated
Whether you’re 18, an immigrant new to the U.S., or someone who’s never used credit — building a credit history from zero is straightforward with the right strategy. Here’s exactly how.
How to use it: Make one small purchase per month ($20-$50), set up autopay for the full balance, and never carry a balance.
Step 2: Become an Authorized User (Month 1-2)
Ask a parent, spouse, or trusted family member to add you as an authorized user on one of their credit cards.
