If it is found an established business customer has an incorrect EIN, do we need to redo all signature cards or can we document the issue and change it on the CIF for them? There are 6 accounts and an SBA loan. There were some changes, way before I was here, in regards to law firm changing hands and EIN number changed also. Customer just noticed it when going over accounts yesterday. I was sent a W-9 this morning

Whether you need to redo signature cards is a business decision and you should ask your legal counsel.

Ok, thanks!! (these accounts are our legal council lol!!)
