Read the first 7 Address and ZIP Code Verification flashcards as text

  1. A package is addressed to '45 Oak St, Apt 3B, Denver CO 80201.' The ZIP code for that Denver neighborhood is actually 80203. What is the error?

    Answer: ZIP code does not match the city and street

    The ZIP code 80201 does not correspond to the correct postal zone for that Denver address; 80203 is the accurate code.

  2. Which of the following ZIP+4 codes is formatted correctly?

    Answer: 90210-1234

    USPS requires ZIP+4 codes to be written as five digits, a hyphen, then four digits (e.g., 90210-1234).

  3. An envelope shows the delivery address as '200 Main Street, Springfield, IL 62702' but the return address city reads 'Springfeld.' Which field contains an error?

    Answer: Return address city spelling

    The return address city 'Springfeld' is misspelled; it should be 'Springfield.'

  4. A mail piece shows '1600 Pennsylvania Ave NW, Washington, DC 20050.' The correct ZIP for that address is 20500. What type of error is present?

    Answer: Transposed digits in the ZIP code

    The digits '0' and '5' are transposed—20050 should be 20500.

  5. A carrier receives a parcel addressed to '88 Elm Blvd, Austin TX, 78701.' What punctuation error is present?

    Answer: Comma placed between city and state instead of after the state abbreviation

    Standard USPS format places the comma after the city name (Austin, TX 78701), not between the city and state as a separator with the state following the comma.

  6. Which address element is MOST important for automated mail sorting machines to read correctly?

    Answer: ZIP code on the last line of the delivery address

    Automated sorting equipment primarily reads the ZIP code on the last delivery address line to route mail to the correct facility.

  7. A letter is addressed to '55 River Rd, Suite 400, Boston, MA 02134.' The suite number for that building is actually 4000. What kind of error is this?

    Answer: Missing digit in the secondary address unit

    Suite 400 is missing a zero; the correct suite number is 4000, making this a missing-digit error in the secondary unit.
