[Postal] 9, Coding and Memory: Why the Street Name Is Never Enough

Lesson nine of the free Quibank postal exam course. Coding and Memory. First, the thing most prep material will not tell you: this section is not on the current Virtual Entry Assessment. It comes from the retired postal exam, and the Quibank bank carries it as bonus practice.

A study book that drills it as your main event is teaching a test you will not sit. It is still worth 20 minutes. Some legacy postings still use the format, and the discipline it teaches is the one the live sections reward. The retired section had two halves.

First you coded addresses with the guide printed in front of you. Then the guide was taken away and you answered from memory, with no notes allowed. Here is the rule the whole section runs on, and it has two parts that have to be true at the same time. The street name must match a listed entry exactly.

And the house number must fall inside that entry's numeric band. The street name on its own never decides the route. So the procedure is three moves. First, read the street name exactly as written, because a directional like North or South, and a suffix like Street or Court, are part of the name.

Second, find every listed entry carrying that name, because one street can appear under more than one route. Third, test your number against each of those bands. Route D only if none of them contains it. Item one.

Route A is 100 to 499 Harlow Street. Route B is 500 to 899 Harlow Street. Route D is the catch-all. Where does 742 Harlow Street belong?

Harlow Street is listed twice, so the name alone cannot answer it. The number picks, and it sits inside the second band. The answer is Route B. Item two, and this is the most missed pattern in the drill.

Pellam Road runs 200 to 599 on Route A, and 600 to 999 on Route B. Where does 1240 Pellam Road belong? The street name matches, which is what makes it dangerous. Both bands stop at 999, so the number is outside every listed range.

The answer is Route D. Item three runs the same trap in the opposite direction. Route A and Route B split Tolliver Street, and Route C is listed as all addresses on Nesbit Lane. Where does 8412 Nesbit Lane belong?

A whole-street entry has no numeric band at all, so there is no upper limit to be outside of. Every address on Nesbit Lane codes to Route C. Those two items are mirror images, and the errors cost the same. Under-using Route D means you recognized a street name and stopped reading.

Over-using it means you sent a legitimate address to the catch-all. The commonest form of that second mistake is the endpoint: a listed range includes both of the numbers that print it, so the first number of a band is inside it. Recap. Name first, then number, and both must hold.

The directional and the suffix are part of the name. One street can sit on more than one route, so find every entry. Range endpoints are inside the range. A whole-street entry has no limit.

Route D only after every listed band has failed. And for the memory half, learn the street-to-route pairs first, then attach the leading digits. Drill the Coding and Memory pool free at quibank.com/en/postal-exam. English, Chinese or Spanish, with no sign-up.

One lesson left in this course, and it is the test-day one: pacing, the accuracy trade, and what your score actually decides.
