Is a text from 28777 legit?
28777 is USPS's ONLY text-tracking short code and only replies to tracking numbers you send; USPS never sends unsolicited package texts with links. The massive USPS smishing wave uses random 10-digit numbers, iMessage/RCS, and foreign senders, not 28777.
A familiar sender is not a guarantee. Even a message that really comes from 28777 deserves the same caution: judge it by what it asks for, and never share a one-time code, password, or PIN because a text looks official.
How to verify any business text
Whatever the sender shows, these five habits keep you safe from smishing:
- Don't tap links in a text you weren't expecting — even if the sender looks right.
- Open the company's official app, or type its web address yourself, instead of following a link.
- Call the number on your card, statement, or the company's official website — never a number the text gives you.
- Never share a one-time code, password, or PIN. A real company will never text asking you to read one back.
- Report smishing: forward the message to 7726 (it spells SPAM) and file it at reportfraud.ftc.gov.
Report a scam text: forward it to 7726 (which spells SPAM) so your mobile carrier can investigate the sender, then report it at reportfraud.ftc.gov. Don't reply or tap any links. More on 7726.
