Can someone give me a list of different airlines frequent flyer accounts sequence? What I mean is that, I need to know how to distinguish if a certain frequent flyer number belongs to delta or aadvantge etc? Does it start with a certain number? And how long or how many digits they are supposed to be? If someone could give me a list please, it would be GREATLY appreciated.

Thank you so much for your time. I am just a newbie and still checking out some posts.

HAve a great day everyone! :)

Just out of curiosity, what do you plan to do with that information?

Why not just sign up for each program and see what numbers they assign you? Or sign up your whole family and then compare numbers for various accounts?

a guess
 

My guess is that the OP has a number that s/he believes to be a FF number but doesn't know which airline it belongs to.

Regardless, a hearty welcome to FlyerTalk to the OP, whatever your reasons for wanting to know!

The OP appears to assume that airline frequent flyer numbers follow some convention like Visa or Mastercard. The first digit of the former is always a 4 and the first digit of the latter is always a 5. Other credit cards use different first digits. Those in the know don't need someone to tell them what kind of card it is - the first digit gives it away.

I doubt the same consistency holds with FF numbers.

AA has changed its number scheme throughout the years. It began in 1981 with a several digit numeral-only pattern. For a while, the format was ABC1234, and then a few years later (continuing today) it was a mixture of numbers and letters.

Idreamtofly, welcome to FlyerTalk. :)

Thank you all for your warm welcome! :cool:

With regard to the first question thrown, the information will be used at work. I am assigned to a frequent flyer department and I need to know at least what are the "conventions" of each arline frequent flyer program. It is not really crucial at all to know but I just got so curious about it. There is a little I know:
Skymiles - 10 digits
AAdvantage - (new) 7 characters, alphanumeric
KLM - starts with 1, 2, 3, or 4.
UAA - 11 digits
USA - 7 characters, alphanumeric
Airmiles - always starts with an "8", 11 digits long

I was able to see a list before but I don't remember where. I kept browsing the net trying to find something but I still am unsuccessful. =)

THanks again and if you happen to find one or a website that might be of help, kindly let me know.

Enjoy the rest of the day! =)

idreamtofly, welcome to FT. A couple of suggestions. To help FTers determine if they have any interest in your topic and decide whether or not they can help you, a more descriptive thread title is a real plus. A lot of FTers want to help but feel like some of their time is wasted looking at threads whose titles are so vague that they can't make initial judgments of interest.

I've also read your latest post and I must admit I'm confused. I'm not sure what working "in a frequent flyer department" means but I believe most FTers would wonder why you would not have any necessary access to/knowledge about those numbers already at your disposal in such a department. When you start asking about specific beginning numbers and sequences of FF cards some folks will, rightly or wrongly, get a bit suspicious. Especially when you are a newbie and no one knows you. There are lots of reasons why FTers might think that that kind of information could be used inappropriately, even though they might not know exactly how. In this day and age we all can get, as some would say, a little paranoid or, as others might suggest, legitimately cautious.

FTers have no way of knowing your motivation and I fear that your additional explanation won't put suspicious/cautious minds at ease. I have no reason to believe your motivation is less than the curiosity you describe. But it is a very unusual request and I hope you can see why some might be concerned. As I said, most FTers want to help but many of us have been misled or played a time or two as well. And perhaps nothing is more sacred to an FTer than his/her FF information, even if questions are being asked about it in a general sense. So, again, welcome to FT and don't take any of this personally. At least you know you've asked what I think is a truly original question.
