  • Census Tract/Block

  • County & County subdivision

What reports are provided by Address IQ?

Address IQ provides several canned reports. The three main reports include:


  • Job Summary (*.ajs) report. The job summary report will provide you with statistics about the job as far as the number of records input, standardized, corrected, elements appended, and results from the optional ACE modules that were enabled.
  • USPS Form 3553 (CASS certificate) that in many situations is still required with the mailing when submitted to the USPS .
  • Error Report. This is an columnar report that details which records could not be assigned within the USPS postal directories, and what error code (reason) was given for not being able
    to make the assignment.


If these reports do not give you the level of detail that you are looking for, you can generate statistics files. These statistics files can be generated in either an ASCII or Dbase3 format that you can then use to generate any type of report.
