A mailer submits an address as '500 Oak Lane, Chicago IL 60614.' Which formatting element is missing?
Answer: Comma after the city name
USPS format requires a comma after the city name before the state abbreviation: 'Chicago, IL 60614.'
An address reads '12 Birch Ct., Apt 5, Miami, FL 33101.' A database check shows the building has no Apt 5; the highest unit is Apt 4. What type of error is this?
Answer: Non-existent secondary unit number
Apt 5 does not exist at that address, making the secondary unit number invalid and the address undeliverable as written.
Which of the following correctly uses a secondary unit designator according to USPS guidelines?
Answer: 456 Pine St Apt 7
USPS prefers the format 'APT 7' immediately following the street address without a pound sign, parentheses, or period.
A package label shows a delivery address in the first line and a return address below it, but both addresses are on the same side of the package in the same size font. What problem could this cause?
Answer: Automated equipment may misread the return address as the delivery address
When the delivery and return addresses are indistinguishable in layout, sorting equipment or carriers may route the package to the sender's address instead.
A letter addressed to '9 Oceanview Dr, San Diego, CA 92101' is returned as undeliverable. The carrier notes the street is actually 'Ocean View Dr' (two words). What error caused the return?
Answer: Misspelled or incorrectly formatted street name
The street name 'Oceanview' (one word) does not match the official USPS street name 'Ocean View' (two words), causing the address to fail matching.
The ZIP+4 add-on code provides how many additional digits beyond the standard five-digit ZIP code?
Answer: 4
ZIP+4 adds four digits to the base five-digit ZIP, narrowing delivery to a specific block face or building.
A customer writes their city as 'St Louis' on a mail piece addressed to Missouri. The USPS preferred city name is 'Saint Louis.' How will USPS systems handle this?
Answer: USPS city-name normalization will typically still match it to the correct delivery point
USPS address-matching software uses an alias table that equates abbreviations like 'St' with 'Saint,' allowing the piece to be correctly routed.
