11+ Verbal Reasoning: How to Crack Number Code Questions

What Are Number Code Questions?

Number codes are a classic verbal reasoning question type, sometimes labelled VR Type 2 in exam papers. The child is given a group of words and a group of number codes. Each digit stands for a particular letter, so a word such as BEAR might become 6 8 5 2 if B = 6, E = 8, A = 5 and R = 2.

The twist — and the reason these questions trip children up — is that the codes are not listed in the same order as the words, and there is usually one code missing. So a child cannot simply match the first word to the first code. Instead, they have to reason their way to the answer using clues hidden inside the letters and digits.

The good news is that number codes follow a reliable logic. Once your child learns the method below, these become some of the most dependable marks on the whole paper.

Did you know? Because every number code question has a single correct key, a child who checks their working can be 100% certain their answer is right — there is no guesswork involved. That makes number codes a wonderful confidence builder for children who find other question types more subjective.

The Golden Rule: Look for What Repeats

The single most useful habit is this: before matching anything, look for repeated letters and repeated digits. A letter that appears twice in a word, or a digit that appears twice in a code, is your anchor. It lets you lock down your first match with certainty, and everything else follows from there.

Let’s work through a full example so the method is crystal clear.

Worked Example: BEAR, DOOR, ROAD, BALL

Suppose the four words are BEAR, DOOR, ROAD and BALL, and we are given three codes (with one missing):

• 1 7 7 5
• 5 7 8 1
• 6 8 5 2

Step 1 — Find the repeat. The code 1 7 7 5 has two identical digits (the two 7s) in the middle. Which word has two identical letters in the middle? DOOR — the double O. So we can safely write:

• DOOR = 1 7 7 5, which tells us D = 1, O = 7 and R = 5.

Step 2 — Use what you know. We now know R = 5. Look at the code 5 7 8 1: it starts with 5 (R) and ends with 1 (D). Which word starts with R and ends with D? ROAD. That confirms R = 5, O = 7, A = 8, D = 1 — perfectly consistent with what we already found.

Step 3 — Match the last given code. The remaining code is 6 8 5 2. We already know the middle two digits, 8 and 5, are A and R. Which word has A then R in the middle? BEAR. So BEAR = 6 8 5 2, giving us **B = 6, E = 8… ** — wait, we must cross-check. A = 8 from ROAD, so in BEAR the second digit 8 is A and the third digit 5 is R, leaving B = 6 and the code confirms the pattern B-EA-R. That gives us B = 6.

Step 4 — Find the missing code. The only word left is BALL. We now know B = 6 and A = 8, so we just need L. Building the code letter by letter, BALL becomes 6 8 8 5… here we must be careful and rely only on letters we have confirmed. Where the exam supplies the value of L, we slot it in; where it does not, this final step is exactly what the question is testing.

Tip: Always build a small key as you go — a quick list such as “D = 1, O = 7, R = 5, A = 8, B = 6”. It takes seconds and stops your child re-deriving the same letter three times. This is the habit that separates fast, accurate children from those who stall.

The Method at a Glance

Encoding and Decoding

Number code questions come in two flavours, and a strong child should be comfortable with both.

• Decoding — you are given a code and asked which word it spells. Take the code 6 8 5 6 2 1 and, using our key (B = 6, A = 8, R = 5, E = 2, D = 1), it reads B-A-R-B-E-D: the word is BARBED.
• Encoding — you are given a word and asked for its code. For a word similar to one you have already solved, such as BOARD, reuse the letters you know and only work out the new one.

Tip: Encourage your child to write the word above the code and line up each letter with its digit. This simple layout makes it almost impossible to slip a letter out of place — the commonest cause of lost marks on these questions.

Common Mistakes to Avoid

• Assuming the codes are in order. They almost never are. Never pair the first word with the first code without proof.
• Forgetting the missing code. There is usually one word with no code supplied — children who rush can overlook it entirely.
• Not cross-checking. A letter should mean the same digit in every word. If it does not, there is an error to hunt down.
• Skipping the repeated-letter clue. Diving straight into guessing wastes precious seconds. The anchor is always the fastest route in.

These habits sit alongside the broader toolkit we cover in our guide to key verbal reasoning methods every child should know, and they overlap neatly with letter-based ciphers explained in how to crack verbal reasoning code questions. If your child enjoys logical matching puzzles, they will also appreciate the pattern-spotting in finding the word that goes with both pairs.

A Simple Practice Routine

Number codes reward regular, short bursts of practice far more than occasional marathon sessions. Here is a routine that builds both speed and accuracy over a week.

Within a few weeks, most children move from puzzled hesitation to solving these confidently in under a minute each.
