What are 9 Digit Numbers?

9 digit numbers are those numbers that have 9 digits and they start from the number 100000000 and end on 999999999. 9 digit numbers can be formed by any number from 0 to 9 keeping in mind that 0 cannot be placed as the first digit. In other words, a nine-digit number cannot start from zero otherwise it will become an 8 digit number. We know that numbers can be represented in the Indian place-value system as well as the International Place Value system.

Place value is the position of each digit in a number, and in the case of 9 digit numbers, there are nine place values. The placing of commas (or periods) is different in the Indian and the International number systems. The smallest 9 digit number in the Indian system is called ten crores, which is 1, followed by 8 zeros and is written as 10,00,00,000. The same number in theInternational system is called a hundred million and is written as 100,000,000.

Reading 9 Digit Numbers

A 9 digit number is read differently in the Indian number system and the International number system. Let us consider a random nine-digit number, 324864701. Let us look at the two ways in which we can write this number. In the Indian number system, it is written as 32,48,64,701. This can be read as thirty-two crores, forty-eight lakhs, sixty-four thousand seven hundred and one. In the International number system, the same number is expressed as 324,864,701 and is read as three hundred twenty-four million, eight hundred sixty-four thousand, seven hundred and one. The correct placement of commas (or periods) is very important in reading the numbers up to 9 digits.

Place Values of 9 Digit Numbers

Any 9 digit number has place values up to 10 crores (or a hundred million). The following part shows the names of the place values in a 9-digit number in the Indian system and the International system:

• Digit 1 – Units

• Digit 5 – Ten Thousands
• Digit 6 – Lakhs / Hundred Thousands
• Digit 7 – Ten Lakhs / Million
• Digit 8 – Crores / Ten Million
• Digit 9 – Ten Crores / Hundred Million

Let us take a random 9 digit number - 338652931, and see how it gets decomposed.

Here, PV = Place Value

Digit 1 PV = 1 × 1	1
Digit 2 PV = 3 × 10	30
Digit 3 PV = 9 × 100	900
Digit 4 PV = 2 × 1000	2000
Digit 5 PV = 5 × 10000	50000
Digit 6 PV = 6 × 100000	600000
Digit 7 PV = 8 × 1000000	8000000
Digit 8 PV = 3 × 10000000	30000000
Digit 9 PV = 3 × 100000000	300000000

As mentioned above, the smallest 9 digit number is called a hundred million. It is written as 1, followed by 8 zeros. However, just the placement of the comma in the two different number systems gives this number two different names. The Indian system of numbers follows the 3:2:2 system of placing commas, so the smallest 9 digit number would be written as 10,00,00,000. The 8th digit from the right denotes the start of a crore, thus, this number would be called 10 crores in the Indian number system. Let us now look at the 3:3:3 system of comma placement in the International number system. This number would be written as 100,000,000. Since the second comma after the 6th digit from the right denotes the start of a million, this number would be called a hundred million in the International number system.
