USPS
The number of digits in a tracking number can vary depending on the carrier and the type of service used. For example, USPS tracking numbers typically have 20 to 22 digits, while FedEx tracking numbers can have 12, 15, or 20 digits. UPS tracking numbers usually consist of 1Z followed by 16 alphanumeric characters. Always check with the specific carrier for accurate information.
There are 199 palindromic numbers between 0 and 1000. These include single-digit numbers (0-9), which total 10, and two-digit numbers (11, 22, ..., 99), which add up to 9. Additionally, there are 90 three-digit palindromic numbers, ranging from 101 to 999, that follow the format aba (where a and b are digits). Thus, the total is 10 (single-digit) + 9 (two-digit) + 90 (three-digit) = 109 palindromic numbers.
The sum is 22 times the sum of the three digits.
The LCM of 5 and 9 is 45 and so 45*22 = 990
10, 12, 14, 16, 18, 20, 22 and just keep adding two until you get to 98.

There are 5460 five digit numbers with a digit sum of 22.

20 and 30 All numbers have at least one common factor.
You call a 22 digit number a 22-digit number. I mean, it's pretty self-explanatory, honey. Just count those digits and slap a hyphen in there every three or four numbers, and voilà, you've got yourself a 22-digit number.
102 = 100 which is the first possible three digit number that is a perfect square. 312 = 961 which is the last possible three digit number that is a perfect square. So there are 22 three digit positive numbers that are perfect squares.
17, 18, 19, 21, 22, and 23
878 three digit numbers have an even number of factors. Every factor of a number has a pair, so there ought to be an even number of factors for every number. However, if a pair of the factors are the same number, then there will be an odd number of factors, that is if the number is a perfect square. Assuming three digit numbers are 100 to 999: From 100 to 999, the perfect squares are 102 = 100 to 312 = 961, a total of 31-10+1 = 22 numbers. So of the 999-100+1 = 900 three digit numbers, 22 have an odd number of factors, so 900-22 = 878 have an even number of factors.
22, if leading 0s are disallowed. 24 if they are permitted.
9, 4, 5, 8, 22, 23, 26, 27, 21 This is assuming that the sequence is 1-digit numbers in reverse alphabetical order, then 2-digit numbers, etc.
The sum is 22 times the sum of the three digits.
