Very well known scam. Some details that give it away:
(1) They used a url shortener that doesn’t let you see the actual domain. (bit.ly)
(2) Website domain is not legitimate.
USPS’s website is usps.com. If the URL doesn’t end in usps.com (meaning usps.fakewebsite.com is still fake) then it’s not legitimate.
(3) Tone: The USPS doesn’t text you like you’re their friend.
(4) The number they’re texting you from is not an SMS short code number (usually 5 digits). Instead you’re getting a text from a 10 digit number with an area code, which means it’s a person/individual rather than an application or service.
