USPS scam ?

I received a text message from the USPS requesting more shipping information as there was some problem
It was on official USPS website right down to the smallest detail
However there was a phone number attached from were it had been sent and when I did open the text some suspicious name came up
The supposedly link wanted name address city state, ph number was I think optional
Being suspicious by nature I did not click link but instead went on the USPS tracking site and put the tracking number the link had provided
Sure as **** the tracking number didnt come up
Upon reading more, the USPS only will text once when its requested
The link went on to say I had 24 hours to reply or the package, item would be returned to the seller
The only thing I ordered was some Jeep parts the other day
Monday im going to call seller to see if and how he sent my parts
