Order your hard copy paper report from each bureau. That is the only way to know for sure exactly what information is / is not correctly listed / missing. The web based reports are no where near as comprehensive.
Once you receive them, review. If something is incorrect - do not dispute online. Write a letter and include any supporting docs necessary (copies of ID, birth certificate, ssn card, etc. ). Send the letter Certified Mail so someone has to sign for it. Then wait for them to update your files.
