Your SkyMiles number is on your membership card, in your Delta account, or by calling Delta directly
Your SkyMiles number is a nine-digit code that identifies your frequent flyer account with Delta Air Lines. You need it to earn miles on flights, redeem rewards, and check your balance. If you have a physical SkyMiles card, the number is printed on the front. If you don't have the card in front of you, you can find it through your online Delta account, your Delta credit card statement, or by calling Delta's customer service line.
The fastest route depends on what you have access to right now. Most people find their number in under two minutes using one of the methods below.

- You can call Delta SkyMiles customer service at 1-800-221-1212 and they will provide your number after verifying your identity.
- Your SkyMiles number stays the same for the life of your account, even if you lose the card or change your contact information.
Check your physical SkyMiles card
If you have your membership card, the SkyMiles number is the nine-digit code printed on the front, usually below your name. The number appears in a larger font than other text on the card.
Keep this card in your wallet or a safe place. You don't need to carry it to earn miles — your number is linked to your account — but it's useful to have when you check in at the airport or need to reference your account number quickly.
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. If you don't remember your password, click "Forgot Password" and follow the reset instructions sent to your email.
Once you're logged in, your SkyMiles number appears on the main dashboard, usually in the upper left or center of the page near your name and current mile balance. It may also be labeled as "Account Number" or "Member Number." You can also find it under "My Profile" or "Account Settings" if it's not visible on the main page.
Bookmark this page or save your number somewhere safe so you can find it quickly the next time you need it.
Check your Delta credit card statement
If you have a Delta credit card issued by American Express or another bank, your SkyMiles number is printed on the front of the card, just like your membership card. It also appears on your monthly statement under "Account Information" or "Member Details."
Log into your credit card account online through your card issuer's website (American Express, Chase, or whichever bank issued your card) and look for your statement. The SkyMiles number is listed separately from your credit card number.
Call Delta SkyMiles customer service
If you can't find your number through any of the methods above, call Delta SkyMiles customer service at 1-800-221-1212. A representative will ask you to verify your identity by providing your name, date of birth, and the email address on your account.
Wait times vary depending on the time of day and how busy Delta is. Early morning or late evening calls typically have shorter waits than midday. Have your identification ready before you call so the verification process moves quickly.
What to do if you don't have an account yet
If you've never created a SkyMiles account, you can enroll for free at delta.com. Click "Enroll Now" or "Join SkyMiles" and enter your name, email, date of birth, and mailing address. Delta will assign you a new SkyMiles number when ready after you complete enrollment.
You don't need to have booked a flight or have a Delta credit card to join. Once you're enrolled, you can start earning miles on any Delta flight, even if you booked your ticket before creating your account — as long as you provide your SkyMiles number at check-in or add it to your reservation afterward.
Frequently Asked Questions
Can I change my SkyMiles number?
No. Your SkyMiles number is permanent and stays with your account for life. If you lose your card, you can request a replacement from Delta, but the number on the new card will be the same. You cannot request a new number or transfer your miles to a different account.
What if I have multiple SkyMiles accounts?
If you've accidentally created more than one account, contact Delta SkyMiles customer service at 1-800-221-1212. They can merge your accounts so all your miles are in one place. Bring the email addresses and SkyMiles numbers for both accounts when you call.
Do I need my SkyMiles number to book a flight?
You don't need it to book, but you should provide it when you make your reservation so the miles automatically post to your account. If you forget to add it during booking, you can add your number to your reservation afterward through your Delta account or by calling Delta.
Is my SkyMiles number the same as my confirmation code?
No. Your SkyMiles number is your frequent flyer account identifier and never changes. Your confirmation code is a six-character code assigned to each individual flight booking and is different for every reservation you make.
What should I do if someone asks for my SkyMiles number online?
Only provide your SkyMiles number to Delta directly through delta.com or by phone at 1-800-221-1212, or to your airline when checking in. Do not share it through email, text, or on third-party websites unless you initiated the contact and trust the source.
