How do I edit USPS tracking #???

[beerman_1001]

I mis-typed 1 digit when I entered my USPS tracking # by hand.  How do I edit??  I normally buy postage thru eBay, but did not this time and paid cash at the counter of USPS.

I am semi-concerned because the # I entered is invalid and does not show any updates.  When I go directly to the USPS tracking system and enter the correct #, it shows the package progressing correctly.

I am only concerned, because the buyer seemed a little sketchy-I don't want to give them an opportunity to receive the item they purchased and then claim, because of the invalid tracking #, that they DIDN'T receive the item.

TIA.

Go to your sold items & next to the Tracking number it says edit
Once you click edit it says add another . 
You add the correct one because you can't change the  one that you entered incorrectly

With either Seller Hub Orders (All Orders or Paid & Shipped) or My eBay Solds, there is an Edit/Add link right next to the tracking number.
