Your SkyMiles number is on your membership card, in your Delta account online, or by calling Delta directly
Your SkyMiles number is a nine-digit identifier that Delta assigns when you open a frequent flyer account. You need it to earn and redeem miles, check your balance, and link your account to flights. The fastest way to find it depends on what you have access to right now — your physical card, your email, or a phone.
If you have your SkyMiles card in your wallet, the number is printed on the front. If you do not have the card but remember your email address, you can log into your Delta account online and see it when ready. If you cannot access either, a call to Delta's SkyMiles phone line will retrieve it in minutes.
Key Takeaways
- Your SkyMiles number appears on the front of your membership card, usually below your name.
- You can find your number by logging into delta.com with your email and password, then viewing your account profile.
- If you do not have your card or remember your login, call Delta SkyMiles at 1-800-323-2323 and have your name and date of birth ready.
- Your SkyMiles number stays the same for the life of your account, even if you lose the card or it expires.
Check your physical SkyMiles card
The easiest method is to look at the card itself. Your SkyMiles number is printed on the front, usually in the lower left or center area below your name. The number is nine digits long and appears in a larger font than other text on the card.
If your card is damaged, expired, or lost, you can request a replacement from Delta, but you do not need the physical card to use your account — your number alone is enough to earn and redeem miles.
Log into your Delta account online
Go to delta.com and click "Log In" in the top right corner. Enter the email address and password associated with your SkyMiles account, then click "Sign In."
Once you are logged in, your SkyMiles number appears on your account dashboard or profile page. Look for a section labeled "My SkyMiles" or "Account Summary" — your number is usually displayed prominently near your name and current mile balance. You can also find it under "Account Settings" or "Profile" if it is not visible on the main dashboard.
If you have forgotten your password, click "Forgot Password" on the login page and follow the steps to reset it using your email address. Delta will send you a link to create a new password.
Call Delta SkyMiles customer service
If you do not have your card and cannot access your online account, call Delta SkyMiles at 1-800-323-2323. Have your full name and date of birth ready when you call.
A representative will verify your identity using this information and provide your SkyMiles number over the phone. Wait times vary depending on the time of day and how busy Delta's lines are, but this method works even if you have no other information about your account.
Check your email for account confirmation
When you first opened your SkyMiles account, Delta sent a confirmation email to the address you provided. Search your email inbox for messages from Delta or noreply@delta.com with subject lines like "Welcome to SkyMiles" or "Your SkyMiles Account Confirmation."
These emails often include your SkyMiles number in the body of the message. Check your spam or promotions folder if you do not see it in your main inbox — confirmation emails sometimes get filtered there.
Look at your airline boarding pass or itinerary
If you have booked a flight with Delta and linked your SkyMiles account to the reservation, your SkyMiles number appears on your boarding pass and in your itinerary confirmation email. Check any boarding passes you have kept or search your email for Delta flight confirmations.
The number is usually listed under a section labeled "SkyMiles Number" or "Frequent Flyer Number" on the confirmation or pass.
Request a replacement card
If your card is lost or damaged and you want a physical copy of your number, you can order a replacement through your online account. Log into delta.com, go to your account settings, and look for an option to order a new card. Delta will mail it to your address at no cost, though it typically takes 7 to 10 business days to arrive.
You do not need to wait for the replacement card to use your SkyMiles number — you can start earning and redeeming miles when ready using just the nine-digit number.
Frequently Asked Questions
What if I have multiple SkyMiles accounts?
Each email address can only have one active SkyMiles account. If you think you have more than one, log into delta.com with each email address you have used. If you find duplicate accounts, contact Delta customer service to consolidate them into a single account with your combined miles.
Can I find my SkyMiles number without logging in?
Yes. Call Delta at 1-800-323-2323 with your name and date of birth, or look at your physical card if you have it. You do not need to log into your account to retrieve your number.
Is my SkyMiles number the same as my confirmation number?
No. Your SkyMiles number is your permanent frequent flyer account identifier and stays the same for life. A confirmation number is a six-character code assigned to each individual flight booking and changes with every reservation.
What should I do if I cannot remember my email address or date of birth?
Call Delta SkyMiles at 1-800-323-2323. A representative can help you locate your account using other identifying information, such as your full name and address. Be prepared to answer security questions to verify your identity.
Does my SkyMiles number change if I get a new card?
No. Your SkyMiles number remains the same throughout your membership, even if you order a replacement card, change your name, or update your address. The number is tied to your account, not the physical card.
