I posted to Oklahoma from Uk. Why is my letter in Texas? So far it's taken 3weeks.

I've had a reply for my tracking number to say it's now in Oklahoma. Thank you USPS.i am very grateful you have almost delivered my letter. I expect it will get there in the next couple of days. I will try to post things even earlier in future.

With the closing of Mineral Wells distribution center about 5 or 6 years ago, your mail would come to North Texas distribution center to be processed. Call North Texas distribution center in Coppell, TX

I hve no idea
