Join Table does not show in Join due to validation errors

[CharlesBanks1]

I am trying to join a table to a parcrl layer based on parcel ID. The validation run indicate that 8000+ records corresponds but after the join nothing shows in the output table. Please help!!! Any Ideas to accomplish this?

Try this:
Use Copy Features tool and copy the joined feature class. Now do you see all your records?

Please can you give more details about your join : Are you using the Add Join tool or the Join Field tool or joining from ArcMap Table of Contents by right clicking and joining the layer and the table? Are you using the Keep All or Keep matching option?
