can po boxes have 6 digits, or do they have 5 at most?

they can as many as that local post office needs. 4, 5, 6.. whatever. the last 4 or 5 digits are usually the zip code

If the number begins with 5, there are still three of the odd digits available to fill the last place.  If a 3 is used for the last place, the others are filled using 1, 2, 3, 4, and so there are 4! arrangements.\nIf 1 is used for the last place, that leaves 2, 3, 3, 4 for the others, and so the number of arrangements is  4!/2! because of the repeated 3.  So that gives \n4! + 4!/2! = 36\n\nIf it begins with a 3, the last place can be filled with 1, 3, or 5, and  the numbers left to fill the remaining four places are all different and so the number of possibilities is\n3*4! =72\n\nIf it begins with a 2 or 4 ( two choices), and the last with 1 or 5 (two choices), there are 4!/2! ways of filling the other places because 3 is repeated.\n2*2*4!/2! = 48\n\nIf it begins with 2 or 4 and ends with 3, then the other four digits are all different, and the number of possibilities is\n2*4! = 48\n\nAdding all these together gives 204.  Yes.

If there was only one digit, there would be 10 (0-9)\nTwo digits, 100 (00-99)\nThree digits, 1000 (000-999)\n\nHey, there might be a pattern here\n\nSo 10 digits, 10,000,000,000 (0000000000-9999999999)

84. so the possible numbers for ones is 0,1,2,3,4,5,6,7,8,9 obviously u can't choose more than 5 or 5 because when u double it it would be 3 digits. so 4,3,2,1 so try 4 if u double it =8 so 8+4=12. and 8 is double of 4.

7 digits are for a single area code so if the phone company exceeds the number of subscribers in an area code, they will split the region and assign a new area code.\n\nBut you have also gotten your math incorrect.  For seven digits there are 10 million combinations (10^7).  Some of these won't be valid numbers (e.g. 911-0000, 000-0000, 555-5555, etc.) but those aside you still have lots of combinations... approximately 8 million, more than the 2.5 to 3 million subscribers in an area code.\n\nThen beyond that, you have an area code.  In the past area codes were restricted to formats that had a zero or one in the middle (e.g. 213, 510, 408, etc.) and the local number would have a 2-9 in the middle (e.g. 932, 857, etc.) but now that they have required us to all dial 1 before our long distance numbers (or dial 10 digits always, in some locations), they don't need this restriction.  Some combinations that could be area codes (411, 800, 877, 911) are reserved for information, toll free numbers, emergency, etc.) so that eliminates a few combinations.  And combinations that start with 0 are 1 are obviously eliminated.\n\nThe format of a 10 digit phone number is:\nNPA-NXX-XXXX\n\nNPA = [2-9][0-8][0-9]  8x9x10 = 720 combinations\nNxx = [2-9][0-9][0-9]  8x10x10 = 800 combinations\nStation = [0-9][0-9][0-9][0-9]  10^4 = 10000 combinations\n\nSo for the U.S. and Canada (actually Bermuda and the British West Indies too), there are roughly 5.76 billion combinations in a ten digit phone number.  There are certainly less than 5.76 billion people in the U.S. and Canada.  Even with the proliferation of cellphones, modem lines, fax machines, etc. (where people have more than one phone number), we shouldn't exceed that many numbers any time soon.\n\nGoing further, 011 is reserved to mean international dialing from the U.S. and Canada, so if the number starts with that, then a country code you can get even more combinations to cover the whole world.

Zero, because that is my area code so I am used to it. Funny how that happens, isn't it? Is this a random number or someone you know, because if it is someone you know, do they live in Yolo County? Haha, the number even starts with a six like all of the ones here. Cool cool!

I don't know what state you live in but yes they will if you organize them right. My post office needed them in zip code order, separated and counted. You should call your post office and see what their policy is.

The last two digits are '25'. \n\n(This is the same for ANY integer power of 5 greater than 1).\n\nThe calculator won't give you the answer since it is not accurate enough.

There are a few depending on the address:\n49014, 49015, 49016, 49017, 49018

Almost certainly not. It doesn't have the correct form, and has the wrong number of digits.

1byte does not always 8 bit it can be 7 bit it can be 6 bit or 9 bit but the secret behind is how much character you want to store if u select 8 bit you can have 256 character ( 2 raised to 8) if u select less u will have less character it is two raised to n if u want to more contact me

There are a few ways to find this, but the answer depends on whether we can repeat numbers in the combination and if the order matters.  \n\nIf we cannot repeat numbers and order matters:\n# combinations = 9*8*7*6*5*4 = 60480\nThere are 9 choices for the first digit, 8 for the second (because one is already taken), and so on.  We multiply the choices for each digit to find the total number of choices.\n\nIf we can repeat numbers and order matters:\n# combinations = 9^6 = 531441\nThere are 9 choices for each of the six digits.\n\nIf we cannot repeat numbers and order does not matter:\n# combinations = 9!/(6!*3!) = 84

its impossible because there needs to be either one less sign or one more number look:\n\nin a the order:\n2 * 4 - 6 + 8 /\n              ^there is an extra sign!!

If it's a legal version just phone the telephone number (or do it on line) and give the 25 digit serial number you will be given a 36 (6*6 I think, or it may be 48 8*6) serial code to enter into your computer. in blocks so you don't mess up , if you do get 1 block wrong it's easy to go back and re do that block.

Some places (I'm thinking it's the UPS Store...)can offer boxes with an actual address.  Sometimes what they do is use their address, and then your box number they put down as a Suite number.  Varies from place to place how they do that, but I'm pretty sure (99.9%) that the Post Office doesn't do this.

According to the USPS: \n"The United States Postal Service® does not keep a firm record of how many ZIP Codes are currently in use, but the number is greater than 42,000."

There is more than one ZIP code for California. The basic ZIP code consists of five digits, not four. The full ZIP code adds another four digits which identifies the post office, so the full ZIP code for any one post office address is nine digits in the form XXXXX-XXXX.\n\nCities would have their own ZIP codes, some larger cities more than one.  Some large buildings would have their own ZIP code.  For example the Empire State Building in New York City has its very own ZIP code.\n\nYou need to be more specific when asking about a California ZIP code because there are many.
