USPS Error Detection Street Name and Number Errors Questions and Answers

Question 1

An operator is verifying an address change. The original address is '1831 E OAKWOOD RD' and the new entry is '1813 E OAKWOOD RD'. Which specific type of error occurred in the street number?

Accepted Answer

Transposition Error

Answer

A transposition error occurs when two adjacent characters are swapped. In this case, the '3' and '1' in the street number '1831' were swapped to create '1813'.

Question 2

Which of the following address pairs contains a spelling error in the street name?

Accepted Answer

470 WASHINGTON BLVD / 470 WASHINGTAN BLVD

Answer

The street name 'WASHINGTON' is misspelled as 'WASHINGTAN' in the second address. The other pairs show differences in suffix, directional, or the addition of secondary information, not a spelling error.

Question 3

An address is listed as '245 MAPLE AVE', but the correct address in the USPS database is '245 W MAPLE AVE'. Why is the missing directional 'W' considered a significant error?

Accepted Answer

It likely refers to a completely different location on another street or side of a dividing line.

Answer

Directionals (like N, S, E, W) are critical parts of an address. Omitting or using an incorrect directional often points to a completely different street segment or an entirely different street, leading to misdelivery.

Question 4

During data entry, a correct address of '9021 BROADMOOR DR' is entered into the system as '9021 BROADMOOR ST'. Which address component has been incorrectly altered?

Accepted Answer

Street Suffix

Answer

The street suffix, which designates the type of road, was changed from 'DR' (Drive) to 'ST' (Street). According to USPS standards, these are distinct and not interchangeable, potentially representing two different physical roads.

Question 5

Compare the following two addresses: Address 1: '4009 VALLEY VIEW LN'; Address 2: '409 VALLEY VIEW LN'. What type of error has occurred in the street number of Address 2?

Accepted Answer

Omission Error

Answer

An omission error occurs when a character is left out. In this case, the second '0' was omitted from the street number '4009', resulting in '409'.
