No. Buying seasoned tradelines is not a legitimate way to build business credit. Paying to be added as an authorized user on a stranger's aged account exists to make a credit file look like something it is not, which is why lenders discount or ignore those entries — and the adjacent products sold alongside tradelines, particularly CPNs, are outright illegal.
What it is: you pay a broker several hundred to several thousand dollars to be added as an authorized user on someone else's old, high-limit, well-paid credit account so its history appears on your file.
Status: not itself a crime for the buyer in most framings, but it exists to misrepresent creditworthiness to a lender. Lenders and the bureaus have known about it for years and discount authorized-user entries in underwriting. Using it to obtain credit you would otherwise be denied is where it becomes loan-application fraud. For business credit specifically it is close to useless, because the business bureaus build files from trade experiences reported against the company's own identity.
What it is: a nine-digit number sold as a lawful substitute for your Social Security number on credit applications.
Status: illegal. There is no lawful "credit privacy number." The numbers sold are typically either fabricated or stolen SSNs, frequently belonging to children, the deceased, or the incarcerated. Using one on a credit application is identity fraud and making false statements to a lender. The Federal Trade Commission has published warnings about this specific scam for years. Anyone selling a CPN alongside a business-credit program is telling you exactly what the rest of the program is worth.
What it is: an entity registered years ago, kept dormant, and sold so the buyer appears to own an established company.
Status: buying a dormant entity is legal in itself. Representing it to a lender as an operating business with history is not. It also rarely works: underwriters look at revenue, bank statements, and reported trade history, none of which a shelf entity has.
What it is: a promise of a specific approval amount — often $50,000 or $100,000 — for a company with no revenue, usually for an upfront fee.
Status: nobody who is not the lender can guarantee a lending decision. In most of these programs the "funding" turns out to be a stack of personal credit cards opened in the owner's name with a personal guarantee, or a merchant cash advance at an effective APR in the triple digits. Advance-fee loan brokering is regulated and, in many states, requiring payment before delivering a loan is prohibited outright.
A business credit file is built from trade experiences the company genuinely incurred and genuinely paid. There is no shortcut that survives underwriting, because the thing being measured is payment behavior over time, and payment behavior cannot be purchased retroactively. The legitimate version costs nothing beyond the goods bought: open net-30 accounts with suppliers that report, buy things the business actually needs, and pay every invoice in full on or before the due date.
The honest timeline: a first reporting vendor account is realistically approved in one to four weeks. A Paydex score generally takes 60 to 120 days after accounts begin reporting. Bank credit without a personal guarantee generally waits on two or more years of revenue history. More on timelines.
Ignition does not sell tradelines, CPNs, shelf corporations, EIN filing, or expedited D-U-N-S numbers, and warns users against all of them inside the product. The EIN is free at irs.gov and the D-U-N-S number is free at dnb.com; the sprint's job is sequencing and paperwork, not selling access to free things.
