Save Your Info Once — Auto-Fill Every Letter

Dispute letters need your exact legal name, mailing address, date of birth, and last 4 of your SSN. Save them here once and every Round 1 / Round 2 / Round 3 letter will auto-fill from this profile.

🔒

Stored on this device only Your name, address, date of birth, and last-4 SSN stay on your device in your browser's local storage. They are not stored on C3's servers — they're added to your letters on your device only when you view, print, or mail them. Use them to auto-fill dispute letters — clear them any time by clearing your browser data.

1 · Legal Name on Credit Report

Use your name exactly as it appears on your credit report — including any suffix (Jr., Sr., II) and middle name/initial. Mismatched names are the #1 reason bureaus mark disputes "unverifiable."

Full Legal Name *

2 · Current Mailing Address

Used as the return address on every dispute letter and where bureau responses are mailed back to.

Street Address *

City * State * ZIP *

3 · Previous Address (Optional)

If you've moved within the last 2 years, include your previous address. Bureaus cross-reference this for identity verification.

I've moved in the last 2 years — add my previous address

Previous Street Address

Previous City Previous State Previous ZIP

4 · Date of Birth

Month and year only — we do not collect the day. Used only to confirm identity match on disputes.

Birth Month * Birth Year *

5 · Last 4 Digits of SSN

Bureaus require this to verify your identity on FCRA disputes. Only the last 4 digits are stored — never your full SSN.

Last 4 SSN *
