Verify 'Held in Customs' alerts before you pay.
Scammers send fake SMS and email alerts claiming a package is 'Held at the Warehouse' or 'Blocked by Customs'. They demand a small fee ($1-$3) for 'redelivery' or 'unpaid tax' to steal your credit card details.
Security Insight
Customs and delivery scams are the most common form of smishing. They rely on the fact that many people are frequently expecting a package. A real courier will never text you a link to pay a small fee to release a parcel.
How to spot a Customs Fee Scam
Real logistics companies and customs agencies follow established billing processes. Watch out for these specific red flags in any delivery-themed alert.
The 'Small Fee' for redelivery
Sent from a personal phone number
Link to a non-official domain
Urgent 'Return to Sender' threat
What IsThisSpam checks before you trust a sender
Quick verdicts are useful, but the real value is understanding why something looks safe, uncertain, or risky.
No Tracking Number provided
Real customs alerts will always reference a specific, verifiable tracking number that you can check on the official courier site.
Requests for Card PIN or CSV
A legitimate payment portal will never ask for your PIN. A scam site will often ask for more data than is necessary for a simple fee.
The site uses a 'Countdown Timer'
Official government or logistics websites never use high-pressure sales tactics like countdown timers to collect fees.
Generic 'Valued Customer' greeting
Official alerts from companies you've shopped with will usually address you by name or reference your specific order ID.
