If 90+ days has passed and the original creditor has closed the credit account, it will immediately be sold to debt collectors. Be aware, it takes debt collectors time to initiate a collection process as they purchase "bulk debt bundles" and have a lot to sift through before starting anything on their end. If a debt collector has not reached out yet begin by sending a copy of the VERIFICATION letter to each reporting credit bureau. Either all the credit bureaus will reach out to the original creditor who will forward the bureau to the new debt owner and force the debt collector to break a few laws to "verify" the debt (thus starting the process of sending letters to the debt collectors to VALIDATE the debt) OR it will be removed from the credit reports. Win-win either way.
