DID YOUR CENSUS FORM LIST "POMONA" INSTEAD OF DIAMOND BAR? A 2010 Census form sometime lists a city name that is not the one you expect to see for your street address. What really matters is the bar code above the mailing address. This locates your household, linking your census questionnaire to your precise location. This bar code on the form guarantees that you will be counted at the right place. It's All About the Bar Code video!

More information about the 2010 Census can be found at www.census.gov/2010census.

Did you receive a Census form with an incorrect address? Here's what to do...

If the CITY and/or ZIP Code are incorrect, but the STREET ADDRESS is correct:

  • Complete the form
  • Correct the city name and/or ZIP Code
  • Mail back the form

If the HOUSE NUMBER and STREET NAME are incorrect, AND you have not completed questions on the form:

  • Write "Wrong Address" on the front of the envelope
  • Leave the questions blank
  • Place the envelope in the mail
  • A Census Worker will follow up with you at a later time

If the HOUSE NUMBER and STREET NAME are incorrect AND you have completed questions on the form, but have not mailed it back:

  • Discard the form in a way that is comfortable for you so your personal information is not made known to the public
  • A Census Worker will follow up with you at a later time

If the HOUSE NUMBER and STREET NAME are incorrect AND you have completed questions on the form AND you have mailed the form back:

  • A Census Worker may follow up with you at a later time

Stop by any government facility or County of Los Angeles library to pick up a new copy and be sure to return it no later than May 1.
