Aged Tradelines
Aged tradelines are authorized-user accounts selected specifically for how old they are. Age is one of the scarcest and most misunderstood variables in the tradeline market, and it behaves differently from limit or utilisation: it cannot be manufactured, it only moves in one direction, and older accounts are genuinely harder to find and price accordingly.
This page focuses on age itself — how a bureau records it, why it matters for your file's average age of accounts, why older lines cost more, and where age stops helping because something else on the file is dragging it down. For the fuller picture of AU tradelines generally, including limit and utilisation, see our seasoned tradelines page.
How account age is actually reported
Every tradeline on a credit report carries a date-opened field, set by the card issuer when the account was originally established, and it is this original date that typically continues to display once you are added as an authorized user — not the date you were added. That is the entire mechanism that makes aged tradelines valuable: the account's real history, going back years, attaches to a file that did not previously have it.
This distinction matters because a common misconception treats 'when I was added' as the relevant date. It generally is not, for how age is calculated by scoring models. What counts is the account's original open date as reported by the issuer.
Date opened versus date reported
Bureaus also track a date-reported or date-updated field, which reflects the most recent month the furnisher sent an update, and this is separate from the date-opened field. A very old account with a recent date-reported entry is not a red flag; it simply means the furnisher's monthly reporting cycle is current. Confusing the two fields is a common source of misunderstanding about how 'active' an aged account looks.
When we describe an account's age to a client, we are describing the date-opened figure, since that is what typically feeds age-related calculations. We confirm this in writing for each specific account before you commit.
Why older lines are scarcer, and priced higher
Card accounts opened ten, fifteen or twenty years ago and still open today are a shrinking pool. Many long-held accounts are closed by their owners over time, and issuers vary in whether they even continue AU reporting on very old accounts. The accounts that remain, are held by cardholders willing to add authorized users, and carry clean, low-utilisation reporting, are a genuinely limited supply.
That scarcity is reflected directly in price. An account with several years of history costs less than one with a decade or more, because the older accounts are harder to source and the sellers of those accounts — the actual cardholders — have less incentive to participate as more time passes.
- Fewer very-old accounts exist in usable condition at all.
- Cardholders who do keep decades-old accounts open are a small and selective group.
- Issuer reporting policy on AU status changes over time and is not guaranteed to continue on any given account.
- Demand is concentrated on the small number of older accounts that are clean and low-utilisation.
How age interacts with average age of accounts
Scoring models generally look at average age of accounts across your whole file, not the age of any single account in isolation. Adding one old account raises the average, but the size of that lift depends on how many accounts you already have and how old they are. Adding a twenty-year-old account to a file with one other six-month-old account moves the average further than adding the same account to a file that already has ten accounts averaging eight years.
This is why we ask about your existing file before recommending a specific account age. Buying the oldest available line is not automatically the right call if your file's structure means a mid-aged account would do just as much for a fraction of the cost.
What age cannot do
Age is one input among several, and it does not offset active problems reporting elsewhere on the same file. Collections, charge-offs and current late payments carry their own weight in scoring models regardless of how old your oldest account is, and adding age to a file that still has unresolved inaccurate items on it does not address those items.
If your file has derogatory marks you believe are inaccurate, unverifiable or obsolete, that is a dispute question, not an age question, and belongs with our credit repair service. Age-focused placements make the most sense once that groundwork is done or is not needed in the first place.
Aged versus seasoned: which page you actually need
We split these two pages because the questions people bring to each are different. If you are trying to understand limit and utilisation alongside age, or you want the full mechanics of how authorized-user reporting works, our seasoned tradelines page covers that ground. If age specifically — how old, how it is calculated, why price scales with it — is the question, this page is the one to read in full before you talk to us.
Frequently asked questions
What counts as an 'aged' tradeline versus a regular seasoned one?
There is no single industry-wide cutoff, but on our site aged tradelines refers to accounts we are recommending primarily for their date-opened history, typically several years or more, as distinct from accounts selected mainly for limit or low utilisation. We tell you the specific account's age before you commit rather than relying on a marketing label.
Does the date I am added become the account's reported age?
No. The date-opened field, set when the issuer originally established the account, is what generally continues to display and feed age-related calculations, not the date you were added as an authorized user. This is the core reason aged accounts have value at all.
Why do older tradelines cost more than newer ones?
Supply. Accounts open for a decade or more that remain active, are held by a willing cardholder, and carry clean low-utilisation reporting are scarce, because many long-held accounts get closed over time and issuer policy on authorized-user reporting is not uniform. Price scales with how hard a given account is to source.
Will an aged tradeline fix a file with collections or charge-offs on it?
No. Age is one factor scoring models weigh among several, and it does not offset active derogatory items reporting elsewhere on your file. If you have items you believe are inaccurate, unverifiable or obsolete, that is addressed through legitimate disputes under the FCRA, which is a separate service from tradeline placement.
Does adding one old account always move my average age of accounts significantly?
It depends on how many accounts you already have and their existing average age. The same aged account produces a larger shift on a thin file with few accounts than on a file that already carries many long-held accounts. We review your existing file before recommending a specific account age for this reason.
How do I know the account's real age before I commit?
We provide the specific account's date-opened information in writing before you agree to a placement, along with which bureaus the issuer reports to and its recent utilisation pattern. You are not asked to take an age claim on trust.
Is there a replacement policy if an aged account is closed or stops reporting?
Yes, placements are covered by our tradeline replacement policy, which we review with you in writing before you commit to a specific account. Reporting is ultimately controlled by the issuer and the bureaus, and the policy sets out what happens if a placement does not perform as described.
