To lock your food stamp card, open your state’s EBT mobile app or online portal, sign in with your card number, and tap the “Lock/Unlock Card” option. Unlocking works the same way in reverse, and the USDA recommends keeping the card locked between shopping trips and unlocking it only at checkout as one of the strongest defenses against benefit theft through skimming.1USDA Food and Nutrition Service. EBT Card Skimming Prevention – Tools and Resources
Why the Lock Habit Works
EBT cards still rely on magnetic stripe technology, which makes them easy to skim. A small device attached to a card reader copies your card data without you noticing. Criminals hold that data, clone your card, and drain your benefits shortly after your next deposit posts. A locked card blocks the cloned copy from working, even if the thief has every digit and your PIN.
Phishing is the other common route in. Scammers send texts, emails, and robocalls pretending to be your state benefits agency and asking you to confirm your 16-digit card number and PIN. No legitimate agency asks for a PIN by phone, text, or email. Ignore the message and call the number on the back of your card instead.
How to Lock Your Card
Which app you use depends on your state. ConnectEBT is used in roughly 15 states, including Georgia, Illinois, Ohio, Pennsylvania, and Virginia. ebtEDGE is used in California and several other states. Your state benefits agency’s website will tell you which one to install, or you can search your state’s name plus “EBT app” in the Apple App Store or Google Play.
The steps look about the same on any platform:
- Install the free app or open your state’s EBT web portal, then create an account or sign in with your card number and identifying information.
- Find the “Lock/Unlock Card” or “Freeze Card” option. It usually sits on the main screen or under account settings.
- Tap to lock and confirm when prompted. An on-screen message should confirm the card is locked.
Many apps let you choose what to block instead of shutting the card down entirely. You can lock everywhere, lock only out-of-state transactions, or block online purchases while keeping in-store use open. The USDA specifically encourages blocking out-of-state and online transactions when you don’t need them, because criminals overwhelmingly use cloned cards in a different state from the cardholder’s home.1USDA Food and Nutrition Service.

Some apps include an auto re-lock timer. You set a window, say 30 or 60 minutes, and the card locks itself again once that window expires. Useful if you tend to forget.
How to Unlock at Checkout
Unlocking is the same process in reverse. Open the app, tap “Unlock,” and confirm. The card is active immediately, so you can do this while standing in the checkout line. Pay, then lock it again before you leave the store. Building the tap into your shopping routine is the single most effective thing you can do to protect your benefits from skimming.
While the card is locked, new benefit deposits and any refunds from online returns still post to your account normally. The lock only blocks outgoing transactions like purchases and cash withdrawals.
Change Your PIN Regularly
A locked card is useless to a thief, but an exposed PIN undoes that protection the moment you unlock. The USDA recommends changing your PIN at least once a month, and ideally before your benefit deposit date, because criminals who skim your card data often wait until fresh benefits arrive before using a cloned card. A new PIN makes previously stolen data worthless.1USDA Food and Nutrition Service. EBT Card Skimming Prevention – Tools and Resources
Avoid obvious PINs like 1234, 0000, or your birth year. Thieves routinely test those combinations against cloned cards. Shield the keypad with your other hand when you enter your PIN at a store terminal. Turn on text or email alerts in your EBT app so you’re notified the instant a PIN change or purchase happens on your account. An unexpected alert is often the first sign something has gone wrong.
If Your Card Is Lost, Stolen, or Already Drained
Locking is for a card you still have. If the card itself is gone, or benefits have already been taken, call your state’s EBT customer service line right away.2Consumer Financial Protection Bureau. What Should I Do if My EBT Card or PIN Is Lost or Stolen, or I See Unauthorized Charges? The number is printed on the back of the card, and your state SNAP agency’s website lists it if you no longer have the card in hand. Federal rules require an immediate hold on the account the moment you report the card missing, and the state assumes liability for benefits taken after that point.3eCFR. 7 CFR 274.6 – Replacement Issuances and Cards Anything drained before you call is much harder to recover.
Federal replacement of SNAP benefits stolen through skimming was authorized by Congress in December 2022, but that authority expired on December 20, 2024, and as of early 2025 had not been renewed. Legislation to make replacement permanent (H.R. 3887) has been introduced. Report the theft to your local SNAP office anyway. Some states run their own replacement programs, and reporting creates the paper trail you’ll need if federal reimbursement is restored.
Chip Cards Are Coming
The USDA has begun rolling out chip-enabled EBT cards to replace magnetic-stripe-only cards.4USDA Food and Nutrition Service. SNAP EBT Modernization Chip cards generate a unique code for each transaction, which makes clones essentially useless. States are switching on their own timelines. Until your state’s upgrade reaches you, the lock feature on your current card is your best available protection, and the habit costs you a few seconds per shopping trip.
