Authorized Users & Joint Credit Explained
Piggybacking vs joint liability — how authorized-user status imports history, what co-signers guarantee, and exit paths for both.
Two record types, one file: which credit checks cost points, which are invisible to lenders, and the rate-shopping rules that protect mortgage applicants.
Every access to your credit file is logged as an inquiry — but the file distinguishes sharply between hard inquiries, generated when you apply for credit, and soft inquiries, generated by everything else: your own checks, lender prescreening, employer reviews, and account monitoring by existing creditors.
Only hard inquiries affect scores, and modestly — typically a few points each, fading within a year though remaining visible for two. The distinction exists because models read credit-seeking behavior: a consumer opening several accounts quickly is statistically likelier to miss payments than one who is not.
A hard inquiry requires your authorization — the application itself — and appears on the version of your report lenders see. Soft inquiries appear only on your consumer-disclosure version: checking your own score, an issuer's monthly account review, and prescreened offer checks are all soft. You can check your own file daily with zero effect.
Rate-shopping rules prevent mortgage and auto comparisons from compounding damage: models collapse multiple same-type loan inquiries inside a 14-to-45-day window (depending on version) into a single scoring event. Credit card applications get no such clustering — each counts individually, which is why rapid card application sprees compound.
FCRA, enforced by the CFPB and FTC, limits report access to permissible purposes — hard inquiries without a credit application or authorization can be disputed for removal. The FTC notes that checking your own report is a soft inquiry and a right, and recent federal legislation has restricted the mortgage 'trigger lead' practice that sold applicant data to competing lenders.
