title: Getting an X.509 digital security certificate for IRS AIR A2A web service
body: <p>My workplace is looking to add the software developer role to our company's relationship with the IRS. I pulled down the latest PDF's from the IRS AIR site and it pointed me at two certificate authorities to have a certificate issued to us. On the <a href="https://www.identrust.com/support/aces" rel="nofollow noreferrer">IdenTrust website</a>, IdenTrust says that as of last month they are no longer issuing the ACES certificates.</p>
  
  <p>My question is, has anyone gotten a confirmation if we are to be using the IGC certificate? </p>
  
  <p>I have verified that I have the latest versions of the PDF's. </p>
  
  <p><strong>Update</strong>:
  We just got an email confirming the information that Das gave. Additionally, the IRS sent us a response to an inquiry we made regarding the certificates, confirming the use of the IGC certificates. They included information that they have updated the Publication 5258 on their site. I've checked the new revision of the publication and it does list the IdenTrust IGC certificate as one of two possibilities.</p>
  
  <p>Thank you for your help.</p>
