 IATA Airline Ticket Numbers

 Can anyone tell me how to translate a ticket number? Example - one of my own E-Tickets edited slightly 724 2117 777 256 I know : 724 = IATA 3-digit "Ticketing Plate" code for Swiss International Airlines. I thought: 21 = Electronic Ticket, or maybe that's just Swiss procedure The rest of the numbers I don't know, but I know ranges are allocated (how??) to each GDS and each Sales Office. I smell an IATA agreement of course... The last of the 13 digits above is a Check Digit. Take the leading 12 digits, divide by 7 and the remainder is the 13th digit. What else is standard? Have I got the check-digit screwed up? Ah, Mr Google has turned up with an entire Book on Check Digit calculations: "Identification Numbers and Check Digit Schemes" By Joseph Kirtland If anyone has a quick and ready guide, please let me know![Edited 2008-08-28 13:20:41]

 Quoting Standby87 (Thread starter): Can anyone tell me how to translate a ticket number?

When I was issuing paper tickets manually many years ago, which I did for my first 3 years in the airline industry, apart from the 3-digit IATA accounting code at the beginning identifying the issuing airline, and the final check digit, if memory correct the first digit after the accounting code matched the number of flight coupons in the ticket form being used (1, 2 or 4 at the airline I worked for), and the remainng 8 digits were just sequential serial numbers as on any other type of ticket or document requiring a unique number.

In your example above, the first three digits of the document number (211) indicate the type of form. For example, a trip pass, an MCO, an automated ticket, and a PTA would all have their own unique, three digit form number. By looking at the first three digits of a document number, an agent could identify the type of document. The remainder of the number (7 777 256) is the serial number.

There are only 7 check digit numbers. They are 0, 1, 2, 3, 4, 5, and 6. Using your number, 724 2117 777 256, the next numbers would be:

724 2117 777 260
724 2117 777 271
724 2117 777 282
724 2117 777 293
724 2117 777 304
724 2117 777 315
724 2117 777 326
724 2117 777 330
724 2117 777 341
and so on

Thanks everyone,

 Quoting Ha763 (Reply 4):There are only 7 check digit numbers. They are 0, 1, 2, 3, 4, 5, and 6

Surely you mean 6? 1->6 inclusive.

It's a Modulus 7 check, so it can never be Zero because there's no remainder 0 case when you divide by a prime number 7?

I honestly got Maths A-Level, but it was 25+ years ago!

Ha763 is correct. 7 mod 7 is Zero. See http://en.wikipedia.org/wiki/Modulo

 YX = 453 Adding more to the list.
 I'd take the awe of understanding over the awe of ignorance any day.
