A Southwest Airlines gift card works like a prepaid voucher for flights. When you purchase one—whether online, at an airport, or through a retail partner—Southwest loads a dollar amount onto the card. That balance sits there waiting to be used for ticket purchases. Unlike a credit card where you get a bill later, a gift card balance is money already paid. Checking your balance tells you exactly how much spending power remains on that card.

Southwest gift cards don't have expiration dates, which means your balance won't disappear if you don't use it right away. However, keeping track of how much you have matters for planning trips and avoiding surprises at checkout. Some people buy gift cards months in advance and forget the exact amount. Others receive them as gifts and want to know what they're working with. That's where balance checking comes in—it's a straightforward way to see your current funds.
The balance you see includes any previous purchases you've made, any remaining amount after partial use, and any added value if you've contributed more money to the card since buying it. If you've used $150 of a $250 card, your balance shows $100. Southwest doesn't charge fees for checking your balance, and the process takes just a few minutes from your computer or phone.
One practical consideration: Southwest gift cards are separate from frequent flyer accounts. Your gift card balance and your Rapid Rewards points are two different things. When you check your gift card balance, you're looking at prepaid money only—not any miles or points you might have earned through flights or credit card spending.
Takeaway: Know your exact gift card balance before shopping for flights so you understand how much budget you have and whether you need to add more funds or pay a difference out of pocket.
Southwest provides multiple methods for checking your gift card balance, and which one you choose depends on your preferences and what you have available at the moment. Each method works reliably and gives you the same information.

The online method through Southwest's website is probably the most common approach. You'll go to the Southwest Airlines website, find the gift card section (usually under "Gift Cards" in the main menu or through a search), and look for a "Check Balance" or "Balance Inquiry" tool. This tool typically asks you to enter two pieces of information: your 16-digit gift card number and a PIN or security code printed on the back of the card. Once you enter these details, the website displays your current balance immediately. This method works 24/7 and requires only internet access on any device.
The phone method offers another straightforward option. You can call Southwest Airlines customer service and speak with a representative who can look up your balance. The phone number for Southwest reservations and customer service appears on their website and on the gift card itself. When you call, have your gift card number ready. The representative will verify some information (like the last four digits of the card or your name) and then tell you the balance. This method is useful if you prefer speaking to a person or if you're having trouble with the online tool.
The third method is checking your balance at the airport or in person. If you're at a Southwest ticket counter, customer service desk, or gate agent location, they can look up your gift card balance using the card number. This option works well if you're already at the airport and want to confirm your balance before purchasing tickets at the counter.
Takeaway: Choose the method that fits your situation: online for convenience and any time of day, phone for personal assistance, or in-person if you're at an airport anyway.
Checking your balance online is the quickest method for most people. Here's exactly how the process works so you know what to expect.

First, open a web browser on your computer, tablet, or phone and visit southwest.com. You don't need to log into a frequent flyer account to check a gift card balance, though you can if you want to. Look for "Gift Cards" in the top navigation menu or search for "gift card balance" using the search function on the site. Southwest makes this tool fairly visible since many customers use it regularly.
When you find the gift card balance tool, you'll see a form with fields to fill in. The form asks for your gift card number—all 16 digits printed on the front of the card. Make sure you enter these numbers exactly as they appear; even one digit wrong will cause the lookup to fail. Below that field is a spot for your security code, which is typically a four-digit PIN printed on the back of the card near the signature area. Some gift cards have this in different locations, so check your specific card.
After entering both pieces of information, click the button to check your balance (the button might say "Check Balance" or "Look Up Balance" depending on when Southwest updated their website). The system processes your request, usually within seconds, and displays your balance on the screen. The balance appears as a dollar amount—for example, "$247.50" or "$1,000.00".
Pay attention to what the screen shows you. Beyond just the balance number, Southwest often displays additional information like when the card was purchased (if relevant) or any pending transactions. Some versions of the tool also let you print the balance information or email it to yourself as a record.
If the system says it can't find your card, double-check that you've entered the numbers correctly. Common mistakes include mixing up similar-looking numbers like 0 and O, or misreading the security code. If you keep getting an error, the phone method might work better.
Takeaway: Have your gift card in front of you when you go online, enter the numbers carefully, and expect your balance to appear within seconds.
Before you check your balance, gather the specific information Southwest's system requires. Having this information ready saves time and prevents frustration.

The gift card number is the most important piece of information. This is a 16-digit number printed prominently on the front of the card. It's usually in the center or lower portion of the card's face. The number might be embossed (raised lettering) or flat printed, depending on your card's design. Look for a series of digits that's longer than any other number on the card. On some cards, the number is repeated in a magnetic stripe format on the back, but you'll want the digits from the front.
The security code or PIN is typically a four-digit number printed on the back of the card. Look near the signature panel on the reverse side. This code serves as a security measure to prevent someone who finds your card from checking the balance. It's similar to the security features on credit cards. Make sure you're copying this code exactly as printed—no spaces, no hyphens.
If you can't find either of these pieces of information on your card, look at the packaging or receipt from when you purchased or received the card. Sometimes this information appears on the original packaging or the sales receipt. If you bought the card as a gift and no longer have the physical card, you might need to contact the gift giver to get the card number.
For phone-based balance checks, you might also want to have your name and the last four digits of the card number handy, as the representative may ask for these to verify your identity. This is a standard security practice.
One note about digital gift cards: Some people receive Southwest gift cards in digital form, delivered via email. Digital gift cards don't have a physical card with printed numbers. Instead, the email will contain a code or reference number. Use whatever identification method the digital gift card email provides when checking your balance online.
Takeaway: Gather your 16-digit gift card number and four-digit security code from the back of the card before attempting to check your balance.
Sometimes the balance checking tool doesn't work on the first try, and knowing why this happens helps you solve the problem quickly.

The most common reason a balance check fails is incorrect number entry. The gift card number has 16 digits, and even a single digit typed wrong will cause the system to reject your lookup. Double-check every digit, especially if you're reading from a physical card and typing into a screen. Pay particular attention to numbers that look similar—like 0 and O, 1
