Hi soccer3
Welcome to the forums. You need to contact the collection agency appearing in your credit report and ask them to give you the necessary information about the respective debt. From there, you will be able to get the details of your creditors.
You can contact the creditors and know the date of last activity in your account to determine the SOL period.
Usually, the date of last activity is furnished in the credit report. If it has not been provided, you can write a letter to the credit bureau and dispute the particular entry.
Also, you can pull your credit report from the other two bureaus and compare the accounts. Hopefully, the comparison of the three credit reports will provide you some more information about your accounts.
