UPS tracking numbers usually consist of 1Z followed by 16 alphanumeric characters. Always check with the specific carrier for accurate information.

The mail service tracking number that starts with "G" typically refers to a package shipped via UPS Mail Innovations.

The answer to your question depends on what level of service is used to ship. Most will have 30 numbers. However, an item I purchased on eBay was just shipped today with USPS expedited and my tracking number is 13 letters and numbers long. This is the format VI000000000US.
The number, 22 billion, has 2 significant digits: 22.
it can be 22 44 66 or 88, yes that is true, but it can also be 20 22 24 26 28, and so on because the person clearly says that the number has two digits and both digits are even, but the person did not say that the even numbers had to be the same
22, 2+2= 4 and half of 22 is 11 which is odd
4(22)
24 is the smallest example, 86 is the highest (unless both digits may be the same when you could have 22 & 88)
That would be 29.
