What are Numbers up to 5-Digits?
Five-digit numbers start from ten thousand and extend up to ninety-nine thousand nine hundred and ninety-nine. These numbers contain integers at the places of ones, tens, hundreds, thousands, and ten thousands. Any positive integer can be placed at these places, keeping in mind that 0 cannot be placed on the ten thousands place. This is because if 0 is placed here it will become a 4-digit number, like, 04356 becomes 4356. The following figure shows how a random 5-digit number, 86953 is placed on an abacus. The place value of the five digits that make up the 5-digit number would be obtained by progressively multiplying the respective figure by 1, 10, 100, 1,000, and 10,000 starting from the rightmost digit and moving to the left.
Smallest 5 Digit Number
The smallest 5-digit number is 10,000 because 5-digit numbers start from 10,000 and the number before 10,000 is 9999 which is a 4-digit number.
Greatest 5 Digit Number
The greatest 5-digit number is 99,999 because the number after 99,999 is 1,00,000 which becomes a 6-digit number.
Place Values of Digits in Numbers up to 5-Digits
As shown above, in a 5-digit number, every progressive place value is the earlier place value multiplied by 10. For example, let us take a number: 37,159. This number can be represented in words, as, 'thirty-seven thousand one hundred and fifty-nine'. The following figure shows the place values of this 5-digit number.
How to Decompose 5-Digit Numbers?
When we see a 5-digit number, the five digits will correspond to the 5 place values - Units, Tens, Hundreds, Thousands and Ten Thousands. Let us see how a 5-digit number can be decomposed into its place values. Let us continue with the same number 20340. 2 is in Ten Thousands place = 2 × 10000 = 20000. Here, 0 is in Thousands place = 0 × 1000 = 0, and 3 is in Hundreds place = 3 × 100 = 300, 4 is in Tens place = 4 × 10 = 40, and 0 is in Units place = 0 × 1 = 0. Hence, the five-digit number can be expressed in the following way: 20000 + 0 + 300 + 40 + 0 = 20340.
Now, how would the 5 place values change if we interchanged some of the digits? Let us change the number 20,340 to another 5-digit number having the same numbers with interchanged digits, like, 32,004. The change in place value of the same 5 digits shows the following results:
- The place value of 2 becomes 2 × 1000 = 2000 (the earlier place value of 2 was 20000)
- The place value of 3 becomes 3 × 10000 = 30000 (the earlier place value of 3 was 300)
- The place value of 4 becomes 4 × 1 = 4 (the earlier place value was 40)
- Zero is the only digit from 0 to 9 whose place value stays the same (zero) irrespective of its position.
In both the numbers given above, all the zero digits have zero place value.
Commas in 5-Digit Numbers
We saw the use of commas in four-digit numbers, and the position of the comma is just before the digit on the hundreds place, that is, to the left of the hundreds place. In a 5-digit number too, only one comma is to be used, and it is to be placed to the left of the hundreds place. For example, the 5-digit numbers 32958 and 20340 can be better expressed as 32,958 and 20,340 which helps in reading the numbers correctly.
How Many 5-Digit Numbers Can Be Formed?
As we said earlier, 02340 is not a five-digit number but a four-digit number 2340. A five-digit number cannot have 0 as the first digit on the left, which is the ten thousand place. Overall, every one of the 5 places of a 5-digit number can be filled up in ten ways, because it can have 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9. So each of the five places can be similarly filled up in ten ways. Therefore, the total number of combinations possible are 10 × 10 × 10 × 10 × 10 = 1,00,000.
Out of these 1,00,000 ways of forming a 5-digit number, we need to take out all the possibilities which have zero in the first position on the left (or the ten thousand place). When there is zero in the first place, the next position (Thousands) can be filled up in ten ways, as can the Hundreds, Tens, and Units places. So, the number of 5-digit numbers that have zero as the first digit are 10 × 10 × 10 × 10 = 10,000. If we subtract these 10,000 ways from the overall 1,00,000 ways, we are left with 90,000. Therefore, there are 90,000 unique 5-digit numbers possible.
Important Notes on Numbers up to 5-Digits
Here is a list of some important notes related to numbers up to 5 digits. These are helpful while we solve questions related to this topic.

Examples on 5 Digit Numbers
Example 1: Find the sum and difference of the greatest 5-digit number and the smallest 5-digit number.
The greatest 5-digit number is 99,999. The smallest 5-digit number is 10,000. Their sum is 99,999 + 10,000 = 1,09,999. Their difference is 99,999 − 10,000 = 89,999.
∴ Sum = 1,09,999 and Difference = 89,999.
Example 2: Write the number name and the expanded form of 68,075.
We see that the number 6 is in the Ten Thousand place, 8 is in the Thousands place, 0 is at the Hundreds place, 7 in the Tens place, and 5 in Ones place. The number name is Sixty-eight thousand seventy-five.
The expanded form of the number is (6 × 10,000) + (8 × 1,000) + (0 × 100) + (7 × 10) + (5 × 1). This can also be written as: 60,000 + 8,000 + 0 + 70 + 5 = 68,075.
Example 3: Place the commas correctly in the following 5-digit numbers.
Solution: The commas are placed just before the digit on the hundreds place. This means we will place the commas as follows:
