Depends, a repo stays on credit for 7 years, and a bankruptcy stays for 11 years, after you have paid off a debt and they have received payment it should be taken of immediately, but you may want to get a free credit report and check and if it is still there call them and ask them about it.
All this advise is pretty much wrong. The credit items that are negative on your account, the tradelines, have to come off your credit report after 7 years from the start of the Original debt its for, or the LAST time you paid them. That last date is the starting clock.
