Third-Party EIN Verification - Deposit Accounts

AVP at a bank ($1.4BUSA)
Does anyone have any recommendations for a service provider that offers verification/validation of an EIN that can be easily used by front line bankers for deposit accounts?  

We had previously tried FIS Chex/BizChex however with them only verifying to other previous FIS inquiries, we received more EIN's that were unable to validate than we were able to get validations for - and discontinued the service.  

Requesting SS4's, and filed tax returns for each new business customer has become challenging - and are hoping there is some service provider that could offer a reasonable alternative. 

Thanks!
