When will the USPS tracking system be working again?

Given the fact that it's a government body, it could take a while.

Depends where she is expecting it fromm and where you live as well as how it's shipping, first class ground priority?

Generally usps is fast

If it's first lass shipping it'll take about 5-10 days usually 7 days.

If it's priority it'll take 2-5 usually 3.

If it's ground it could take up to 2 weeks.

Hope that gives you an idea.

Why in the world would you ask this question of YA users rather than asking the ups? Oh that's right, everyone knows everthing here given that they're all knowing experts. Plus it's a nice excuse to get in a nasty little jab. Cute. Hope she got her package.

Millions of pieces of mail use tracking. It does not stop working. If nothing shows up when you enter your number, that means it has not been scanned yet.
