Mortgage lenders don't cherry‑pick a single bureau; they request a tri‑merge credit report that bundles Equifax, Experian and TransUnion data. The combined file satisfies investor rules, feeds automated underwriting engines, and presents a complete view of a borrower's credit history (as we covered above regarding the top‑ranked bureau).

• Includes every hard inquiry, payment‑status update and public record across all three bureaus.
• Aligns with Fannie Mae and Freddie Mac requirements for conforming loans.
• Reduces the chance of a hidden delinquency slipping through underwriting.

Because lenders pull the full tri‑merge, keeping an eye on each credit file prevents surprise mortgage inquiries and helps maintain a clean score. For the official source, see Fannie Mae underwriting guidelines.

Credit‑card issuers most often pull TransUnion, not the Experian bureau that topped the overall pull‑volume rankings earlier. A 2023 industry report shows roughly 45 % of all credit‑card inquiries hit TransUnion, while Experian receives only about a quarter of those pulls 2023 credit‑card pull analysis.

A smaller group of issuers still relies on Experian or even Equifax, typically legacy banks that built their risk models around those datasets. This split means a consumer's card‑approval score can differ from the score most lenders see, and it foreshadows the next section on which bureaus landlords prefer.

Landlords most commonly pull Experian when they run a tenant‑screening check, because Experian's rental‑specific data set is the most widely integrated into property‑management software and because industry surveys show it leads the bureau‑pull market for residential leases.

• Experian handles roughly 55 % of landlord pulls (2022‑2024 data from the Consumer Financial Protection Bureau).
• Equifax accounts for about 30 % of pulls, often used by regional property managers who value its utility‑bill and eviction records.
• TransUnion makes up the remaining ~15 % and is chosen when landlords need the latest credit‑score models for higher‑income rentals.
• Major screening platforms such as Experian's Rental Screening service and the National Association of Realtors landlord screening report both cite Experian as the default source for most U.S. rentals.
• Some landlords supplement the primary check with a secondary pull from another bureau to verify discrepancies or to capture additional public‑record data.

Employers pull Equifax for the bulk of their bureau pulls; recent 2022‑2024 employment‑screening data shows roughly 68 % of applicant checks originate from that bureau because its reporting platform delivers the quickest, most detailed employment‑report package (see 2022‑2024 employment credit pull data).

A minority of firms opt for Experian or TransUnion, often due to legacy contracts, but the industry default remains Equifax.

Because Equifax handles the most employment checks, job seekers should prioritize its score and history. Regularly review your Equifax report, dispute inaccuracies promptly, and consider a monitoring service - steps that the next section, 'why monitor the busiest bureau,' will explore in depth.

Monitoring the busiest bureau - currently Experian, which processes roughly 30 % of all credit pulls from 2022‑2024 according to industry reports - matters because most lenders, landlords, and employers send their inquiries there first. Errors, unauthorized accounts, or fraudulent activity will surface on Experian before they appear on Equifax or TransUnion, giving you the earliest warning sign.

Catch problems early, dispute inaccuracies quickly, and protect your score before a major loan or rental application. By focusing on Experian you also limit duplicate monitoring costs and streamline the 'grab reports from your lead bureau' step that follows later in this guide. 2023 credit bureau pull volume study

After you have Experian's report, you can compare it to the Equifax and TransUnion statements covered in the next '5 pull myths you believe' section.

The below content will be converted to HTML following it's exact instructions:

• Myth: All lenders pull the same bureau; in fact, mortgage lenders favor Equifax, credit‑card issuers lean toward Experian, and landlords usually check TransUnion (Equifax mortgage pull data, Experian card pull trends, TransUnion landlord checks).
• Myth: A hard inquiry scars your report for two years; actually, most scoring models stop counting it after 12 months (CFPB hard‑inquiry guide).
• Myth: Multiple checks in a short span permanently tank your score; rate‑shopping windows treat mortgage, auto, and student‑loan inquiries as a single pull for up to 45 days (FICO rate‑shopping policy).
• Myth: Soft pulls never affect your credit; they don't enter FICO calculations, yet alternative models sometimes factor them into risk assessments (Experian soft‑pull impact).
• Myth: Only the most‑used bureau matters for your score; each bureau holds distinct data, so a negative item on Experian may be absent from Equifax or TransUnion (TransUnion data differences).

Experian remains the busiest bureau, handling about 55 % of all pulls from 2022‑2024, so any shift in its processes reshapes the whole market. The first trend to watch is the surge in real‑time, API‑driven checks by mortgage lenders, which cut approval times but also raise the volume of instantaneous inquiries. Recent data from FDIC's credit‑inquiry report shows a 12 % yearly increase in these digital pulls.

A second trend is the growing use of alternative data sources - utility payments, rental histories, and even subscription services - to supplement traditional bureau checks. This practice blurs the line between the three major bureaus, as each integrates more non‑bank information to stay competitive. Consumer Financial Protection Bureau research indicates that lenders adding alternative data see a 7 % reduction in denied applications.

Finally, regulatory revisions to the Fair Credit Reporting Act, finalized in 2023, tighten consent requirements for non‑mortgage pulls. As a result, employers and landlords are shifting toward the top‑ranked bureau to ensure compliance, while credit card issuers are consolidating pulls to a single bureau to simplify reporting. FTC final rule summary outlines the new consent standards that will drive this consolidation.
