A credit score is a statistical number that evaluates a consumer's creditworthiness and is based on credit history. Lenders use credit scores to evaluate the probability that an individual will repay his or her debts. A person's credit score ranges from 300 to 850, and the higher the score, the more financially trustworthy a person is considered to be.
Assuming there has been no activity on the account, it should come off your credit report 7 years and 180 days after it first went late. You are probably right that the account keeps getting resold. Those sometimes sell for pennies on the dollar, and the collectors may come after people who are no longer legally required to pay. You can read more here: Does Your Old Debt Have an Expiration Date?
After you’ve taken advantage of your annual freebies, use a personal finance site for frequent, ongoing credit monitoring. Monitoring your scores and reports can tip you off to problems such as an overlooked payment or identity theft. It also lets you track progress on building your credit. NerdWallet offers both a free credit report summary and a credit score, updated weekly.
SPECIAL NOTE ABOUT COLLECTIONS: Collection agencies will often report debts to the credit bureaus in an attempt to collect from the consumer. This is perfectly legal as defined by the Fair Debt Collection Practices Act. The issue here is that, intentionally or not, collection agencies sometimes report to the credit bureaus using a newer “purge from” date despite the fact that this is not allowed under the Fair Credit Reporting Act. The result of this misreporting is that the collection item will remain on the credit file longer than they should. If that happens, you can dispute the old account.
Only one website is authorized to fill orders for the free annual credit report you are entitled to under law — annualcreditreport.com. Other websites that claim to offer “free credit reports,” “free credit scores,” or “free credit monitoring” are not part of the legally mandated free annual credit report program. In some cases, the “free” product comes with strings attached. For example, some sites sign you up for a supposedly “free” service that converts to one you have to pay for after a trial period. If you don’t cancel during the trial period, you may be unwittingly agreeing to let the company start charging fees to your credit card.
