Read the first 6 Error Detection Address and ZIP Code Matching 1 flashcards as text

  1. A package is addressed to 2847 Oak Grove Blvd, Nashville, TN 37211. The automated sort record shows 2874 Oak Grove Blvd, Nashville, TN 37211. What is the nature of the error?

    Answer: The street number digits have been transposed

    The original street number is 2847, but the sort record shows 2874 — the digits '4' and '7' have been transposed. All other fields, including the ZIP code and street name, are identical.

  2. The correct delivery address is 634 W Maple St, Tucson, AZ 85701. The carrier database entry reads 634 W Maple St, Tucson, AR 85701. What correction is required?

    Answer: The state abbreviation must be corrected from AR to AZ

    AZ is the USPS abbreviation for Arizona, while AR is Arkansas. The city Tucson is in Arizona, so the state field contains an incorrect two-letter abbreviation. All other fields are correct.

  3. An envelope is addressed to 1122 NE Riverside Ave, Kansas City, MO 64116. The sort machine label reads 1122 NW Riverside Ave, Kansas City, MO 64116. Which field contains the discrepancy?

    Answer: The street directional prefix has changed from NE to NW

    The original address uses the directional prefix NE (Northeast), but the label shows NW (Northwest). On a grid-based city street layout this could route the piece to an entirely different part of town.

  4. The origin record lists 88 Beacon St, Boston, MA 02108. The scanned entry for the same piece reads 88 Beacon St, Boston, MA 02180. What error has occurred?

    Answer: The final two digits of the ZIP code have been transposed

    ZIP code 02108 is a valid Boston ZIP, whereas 02180 corresponds to a different area. The last two digits '0' and '8' have been swapped, creating a routing error that could send the piece to the wrong destination.

  5. A letter is addressed to 3310 Chestnut St, Philadelphia, PA 19104. The carrier route record shows 3310 Chesnut St, Philadelphia, PA 19104. What must be corrected?

    Answer: The street name contains a spelling error

    The correct street name is 'Chestnut' (with the letter 't' after 'Ches'), but the record omits that 't', producing 'Chesnut.' The address number, city, state, and ZIP are all accurate.

  6. A mail piece shows the delivery address 5901 Linden Blvd, Brooklyn, NY 11203. The automated processing system reads 5901 Linden Blvd, Brooklyn, NY 11203. What conclusion should the clerk draw?

    Answer: The address record is correct and no action is required

    Every element of the handwritten address and the system record — house number, street name, city, state, and ZIP code — is identical. There is no discrepancy, so no correction is needed.
