The requirements and eligibility rules for a credit score attach to the credit file, and a file qualifies for a FICO Score under 3 conditions: at least 1 account open for 6 months or longer, at least 1 account reported within the past 6 months, and no deceased indicator on the file. VantageScore Solutions applies looser conditions and scores files with as little as 1 month of history. No application, income test, employment test, or citizenship test exists for scoring: the requirements govern data inside a file at Equifax, Experian, or TransUnion, never attributes of the person. A credit score is a 3-digit number a scoring model calculates from credit report data, and the full definition sits on the definition page of this cluster (internal link: F0391, “What is a credit score?”).
What does FICO require before a FICO Score exists?
FICO requires 3 file conditions at the bureau whose data feeds the calculation, per FICO documentation of the FICO Score minimum scoring criteria. The 3 criteria are:
- Hold at least 1 account open for 6 months or longer.
- Hold at least 1 account reported to the bureau within the past 6 months.
- Hold no indication of a deceased consumer on the file.
Each criterion measures the file, and no criterion measures the consumer. Criterion 1 sets a minimum history depth of 6 months on the oldest qualifying account. Criterion 2 sets a recency window of 6 months: a furnisher report inside the window keeps the file scorable, and a closed account counts toward criterion 2 while the furnisher continues to update the account. Criterion 3 blocks the calculation outright, because a deceased indicator marks the file as belonging to a consumer who no longer borrows. A file that fails 1 criterion receives a no-score response instead of a number.
What does VantageScore require before a VantageScore exists?
VantageScore requires 1 reported account and scores a file with as little as 1 month of credit history, per VantageScore Solutions documentation. The activity window extends to 24 months: VantageScore generates a score from a file whose most recent reported activity is up to 24 months old, against the 6-month recency window in the FICO criteria. The wider window reaches dormant files, and VantageScore Solutions states that its models score about 37 million consumers whom conventional scoring models leave unscored, including consumers with sparse files and consumers returning after years without credit use.
FICO sets the gate at 6 months of history and 6 months of recency, and VantageScore sets the gate at 1 account, minimal history, and 24 months of recency. The same consumer holds a VantageScore and no FICO Score in the gap between the 2 gates, for example at 3 months of history on a first credit card.
Which consumers have no credit score at all?
About 45 million US adults have no usable credit score: 26 million are credit invisible with no credit file at any bureau, and 19 million hold files that are too sparse or too stale to score. The Consumer Financial Protection Bureau (CFPB) published the 2 counts in the May 2015 report “Data Point: Credit Invisibles”: the 26 million credit invisible consumers form about 11 percent of US adults, and the 19 million consumers with unscorable records form about 8.3 percent. The 2 groups fail the requirements at 2 different points. A credit invisible consumer fails before the file stage: no furnisher has ever reported an account, so the 3 bureaus hold no record to evaluate. A consumer with an unscorable record passes the file stage and fails the criteria stage: the file holds too few accounts, accounts below the minimum age, or activity older than the recency window.
The CFPB counts concentrate in defined populations. The 2015 report found higher credit invisibility among consumers in low-income neighborhoods, and among Black and Hispanic consumers, at rates above the national 11 percent figure. Cash-based households generate the pattern: rent, utilities, and cash purchases create no tradeline at a bureau in the standard reporting system, so a consumer with decades of on-time rent payments and no reported account stays invisible to both models.
Which identity data does a credit file require?
A credit file requires reported accounts matched to a consumer through 4 identifiers: full name, current address, date of birth, and a Social Security number or an Individual Taxpayer Identification Number (ITIN) as the tax-identifier field. No federal law requires a Social Security number for a credit file to exist. The Internal Revenue Service (IRS) issues ITINs to residents without Social Security number eligibility, furnishers report accounts for ITIN holders, and the 3 bureaus build files from the reported data with the ITIN in the identifier field. An immigrant with 1 reported credit card and an ITIN meets the identity basis of a file from the first furnisher report.
A furnisher reports the name, address, date of birth, and tax identifier with each account, and the bureau — a consumer reporting agency in the language of the FCRA — matches the record against existing files on those 4 fields. A record with a mismatched name spelling or an old address lands in a mixed file or a fragmented file, and the consumer then holds 2 partial files, each thinner than the combined record. A partial file fails the FICO criteria more often, because the 6-month account and the recent report sit in different fragments.
Does an authorized user account satisfy the requirements?
An authorized user account satisfies the account criteria when the card issuer reports the tradeline to the authorized user’s file, per the reporting practice FICO documents for authorized user accounts. Many issuers report authorized user tradelines to Equifax, Experian, and TransUnion, and the reported tradeline enters the authorized user’s file with the account open date, the balance, the limit, and the payment status. The tradeline then counts inside the criteria like any reported account: an authorized user tradeline open for 6 months or longer supplies criterion 1, and monthly issuer reporting supplies criterion 2.
The qualification is reporting, and reporting varies by issuer. An authorized user on an account at an issuer that reports only the primary cardholder gains no file data and no eligibility from the account. FICO documentation treats reported authorized user tradelines as genuine file data, and FICO Score 8 applies additional screening to tradelines that match purchased authorized user patterns from stranger accounts. The family pattern is the standard case: a parent adds a child as an authorized user, the issuer reports the tradeline, and the child holds a scorable file before holding any account as a primary borrower.
What is not required for a credit score?
Seven personal attributes carry no requirement in either model: income, employment, bank account balance, an application, consent to the calculation, a fee, and United States citizenship. The 7 absences follow from the design of scoring: a model reads a credit file, and a credit file contains accounts, balances, limits, statuses, and inquiries — never income figures, employers, or deposit balances. A consumer with no job and 1 reported card account has a score. A consumer with a $200,000 salary and no reported account has no score. Eligibility for the score and eligibility for a credit product are 2 separate systems, and the second system adds the requirements the first system lacks.
The product system runs on different rules. The Equal Credit Opportunity Act (ECOA) of 1974 and Regulation B govern how a lender evaluates an application, and a lender adds income, employment, and debt-to-income tests inside underwriting. The Fair Credit Reporting Act (FCRA) of 1970 adds a requirement on the pull rather than on existence: a lender obtains a score only under a permissible purpose, such as a credit application. In 1 line: a score requires a qualifying file, a loan requires a qualifying applicant, and the 2 qualifications share no criteria.
Which conditions block a score on an existing file?
Three conditions block a score on an existing file: a deceased indicator, a stale file with no furnisher report inside 6 months under the FICO criteria, and a file that holds inquiries and personal data but no tradeline. The deceased indicator blocks both models at the calculation step, and the indicator sometimes sits on a living consumer’s file as a furnisher or bureau error. A consumer in that position disputes the record under Section 611 of the FCRA, the bureau investigates within 30 days in the standard case, and the corrected file scores again at the next calculation. The stale-file block operates silently: accounts close, reporting stops, the 6-month FICO recency window lapses, and the score disappears even though the file and its history remain stored at the bureau. A VantageScore continues to generate on the same file for up to 24 months of inactivity under its wider window.
A security freeze blocks nothing in this list: a freeze restricts access for new lenders, and the file continues to score for the consumer and for existing creditors with a permissible purpose. Existence, access, and eligibility are 3 separate states of 1 file — this page governs existence, the freeze governs access, and underwriting governs eligibility.
How do the FICO and VantageScore requirements differ?
The 2 models differ on 3 of the 4 criteria rows: minimum account age, recency window, and the size of the population that passes the gate. The table states each criterion once, from the documentation of each model company.
| Criterion | FICO Score | VantageScore |
|---|---|---|
| Minimum accounts | 1 reported account | 1 reported account |
| Minimum account age | 1 account open 6 months or longer | Scores a file with 1 month of history |
| Recency window | 1 account reported within the past 6 months | Activity up to 24 months old scores |
| Deceased indicator | Blocks the calculation | Blocks the calculation |
Both models require 1 real tradeline and a living consumer. FICO then filters on depth and recency at 6 months on both axes, and VantageScore filters at 1 month of history and 24 months of recency. The 37 million consumer gap that VantageScore Solutions reports between conventional scoring and its own models lives inside those 2 loosened rows. A consumer plans around the stricter gate in practice, because a mortgage, an auto loan, or a card application draws a FICO Score in most lending channels (internal link: F0393, “What are the types of credit score?”).
Frequently asked questions
Does a consumer apply for a credit score?
No, a credit score has no application, no fee, and no approval step: a scoring model generates the score when a lender or a consumer requests it, if the file meets the model criteria. The file forms automatically from furnisher reports. Eligibility is a data state, not a granted status.
Does a person need a Social Security number to have a credit score?
No, a credit score requires a reported account matched by name, address, and date of birth, and an ITIN from the IRS serves as the tax-identifier field where no Social Security number exists. Furnishers report accounts for ITIN holders. The 3 bureaus build the file from those reports.
Does a teenager have a credit score?
A teenager has a credit score when a furnisher reports an account to the teenager’s file, most often an authorized user tradeline from a parent’s card, and no federal minimum age governs file existence. The age of 18 governs signing a credit contract as a primary borrower. File existence and contract capacity are separate rules.
Does income change eligibility for a credit score?
No, income never enters a credit file or a scoring model, so income changes neither eligibility for a score nor the score value. A lender tests income separately inside underwriting for a product. The score gate reads accounts, ages, recency, and the deceased indicator only.
Why does a score disappear after years without credit use?
A FICO Score disappears when no furnisher reports an account within the past 6 months, because the recency criterion fails even though the file and its history stay stored at the bureau. VantageScore continues on the same file up to 24 months of inactivity. New reported activity restores FICO scorability.
Does a credit freeze remove eligibility for a score?
No, a security freeze restricts lender access to the file and leaves scorability untouched: the file continues to generate scores for the consumer and for existing creditors. A freeze changes who reads the score. The criteria for generating the score stay identical.
How many consumers in the United States have no credit score?
About 45 million US adults have no usable credit score: 26 million are credit invisible with no file, and 19 million hold unscorable records, per the CFPB report of May 2015. The 2 groups form about 19 percent of the adult population combined. New tradelines move a consumer out of either group.
Does a deceased indicator error remove a score permanently?
No, a deceased indicator blocks calculation while it sits on the file, and a dispute under Section 611 of the FCRA removes a false indicator after a bureau investigation of 30 days in the standard case. The file scores again at the next pull after correction. The block is a data error state, not a permanent status.
Summary
The requirements and eligibility rules for a credit score attach to the credit file: FICO requires 1 account open for 6 months or longer, 1 account reported within the past 6 months, and no deceased indicator, and VantageScore scores thinner and older files under a 24-month activity window. About 45 million US adults sit outside both gates as credit invisible or unscorable, per CFPB research of May 2015.
