That depends on the credit card!

yea, if you have more than 75% of the bill. I would Further guess they require one serial # and at least 1 to 4 digits of the second.

I am assuming you are in the US. If yes then this answer would apply to you...I uswed to work for JCPenney Credit Cards so I know a bit about Credit Rating. The more credit you apply the more credit rating is affected. particularly if the application is declined. So the smart thing to do would be to have not more than two or three cards.

If you are trying to use a credit card number to purchase something, beware that the site you are at will most likely try to process the card number you give them. In that case a made up number will be rejected. A credit card company uses a certain number rotation for its credit cards. They are different per regions in the US and other countries.

YOU don't USE that one. The merchant/restaurant does. They just SWIPE your card and enter the amount and they get an approval or denial!

119 if I remember my trip to the US Mint correctly.\n\nOdd, that it has 119, why not 120? or 115?

A lot of factors play into your credit rating.  Generally, it is good to HAVE two or three credit cards.  You will actually lose points on your credit rating if you don't have any credit cards, or if you have more than four.  Another way to build your credit with those cards is to use them sparingly and always pay on time.  You credit report will show every time you made a late payment to a credit card co., mortgage co., or anyone that you owe. So... in answer to your question, two cards is better than one, but no more than three.

100 - You only have 1 choice for the first digit (7) times 10 choices for the second digit (0 thru 9) times 10 choices for the third digit (0 thru 9). 1 X 10 X 10 = 100. Another way of looking at it is your choices are from 700 thru 799, which is 100 choices.

Not many.....just keep enough cash on you to last you a few days, asit shouldn't take long for your real checks to come in.( I hope you told them to start your checks with the number 1000...some stores also have a policy about not taking checks at all with a number of less than 500 or 1000.)

792\n\n1 thru 9 = 9 digits\n10 thru 99 = 180 digits (90 numbers with 2 digits each)\n100 thru 300 = 603 digits (201 numbers with 3 digits each)\nTOTAL = 792

The formula you are talking about looks at the combined balance.  Basically they look at all of your credit limits combined.  You don't want to be using too high of a percentage of this total balance, but I'd say 24% is perfectly fine.  Your limit on individual cards is not really a factor.  Also, having too many credit cards can negatively affect your credit score.  Typically you want to limit your number of credit cards to 2-3.

tell them its a credit card and mark its a credit card---do not punch in any four digit code numbers.

My 1st 5 #'s are: 10,34,25,59,12 and my last # is 3.\nMy equation was *59/*10=5.9 , *25-5.9=19.1, *34-19.1=14.9 , 14.9-*12=(2.9). I figuerd since my end result was really close to my last # it would count if you rounded up. Does it?

It could be any number between 0000 and 9999. If you need a list, start by writing down 0001, then 0002, then 0003, until you get to 9999. There's your list.
