Common Application Issues

In order to help expedite the application processing time for our users, the CSOS Support Team has compiled the following list of the most common application errors and how to avoid them. You may also find answers to our most common questions by visiting the Q and A's page.
  • Verify that the application package is complete by reviewing the checklist on the last page of the application. Package requirements vary by applicant type.
  • To ensure faster application processing, it is recommended that applications be opened in an Adobe PDF format from the link provided on this web site and filled out electronically before printing. Do not use typewriters or submit hand written applications when possible.
  • A middle initial is required on the applications. Please use 'X' if you do not have a middle initial.
  • Applications may not be printed using both sides of a single sheet of paper.
  • At least one identification must be a U.S. Government issued photo ID (a driver’s license or passport). The other form of identification is not required to include a photo. Examples for the second form of ID include pharmacist licenses, employee IDs.
  • Do not photocopy multiple applicant identifications on the same sheet of paper. Each application needs to be accompanied by a photocopy of the required identification for that applicant only.
  • Identification photocopies must be clear and able to be read.
  • Do not submit multiple applications for one person.
    • A Registrant wishing to also be a CSOS Coordinator may indicate this on the CSOS DEA Registrant Certificate Application rather than submitting an additional Coordinator application.
    • All Registrant subscribers have signing authority and therefore should not submit an additional application as a CSOS Power of Attorney. All other individuals wishing to have signing authority for the DEA Registrant must submit a valid CSOS Power of Attorney application package.
    • CSOS Coordinators requiring signing authority may indicate this on the CSOS Principal/Alternate Coordinator Certificate Application and therefore should not submit an additional application as a CSOS Power of Attorney.
  • The number of addendums field on the application is required. This number refers to the number of CSOS Certificate Application Registrant List Addendum forms (up to five) that are submitted with the application. If not submitting any Addendum forms, please enter '0' in this field.
  • Verify that all application forms are signed and notarized where required.
