The standard format for a Delta Air Lines ticket number in 2026 is a 13-digit numeric code that always begins with the three-digit airline prefix "006". This prefix is the industry identifier for Delta-issued tickets. The full number typically appears on your electronic flight receipt as 006-XXXXXXXXXX. It is important to distinguish this from your "Confirmation Number" or "Record Locator," which is a 6-character alphanumeric code (e.g., G8XYZ9). The 13-digit ticket number is the actual financial record of your fare and is required if you are trying to lookup an eCredit, process a refund, or link a partner flight. In 2026, if you book a flight through a partner like Air France but the ticket is issued by Delta, it will still start with "006." Conversely, if you book through a travel agency, the number might start with a different prefix, but for any "pure" Delta transaction, those first three digits are the definitive marker.
A Delta Air Lines ticket number is a 13-digit sequence that always begins with the three-digit airline code 006. The full format looks like 006XXXXXXXXXX. This number is unique to your specific purchase and is different from your 6-character "Confirmation Number" (Record Locator). In 2026, you can find this 006-prefix number at the bottom of your emailed receipt or on your digital boarding pass under the "Passenger Information" or "Receipt" section. This ticket number is critical for managing your booking on partner airlines or for requesting a "re-issue" of a lost ticket. For 2026 travelers, a "pro-tip" is that if you book a flight through a third-party site (like Expedia) but it is "Delta-ticketed," the number will still start with 006; if it starts with another code (like 016 for United), then that airline is the "issuing carrier" even if you are physically flying on a Delta plane.
