If you're having problems with USPS, the first thing to do is check the available methods. Here's the current USPS shipping methods:
| Name | Method |
|---|---|
| Priority Mail | Priority Mail 1-Day |
| Priority Mail | Priority Mail 2-Day |
| Priority Mail | Priority Mail 3-Day |
| Parcel Post | Standard Post |
| Express Mail | Priority Mail Express 1-Day |
| First Class | First-Class Mail Parcel |
| Media Mail | Media Mail |
| Library Mail | Library Mail |
| Global Express Guaranteed | Global Express Guaranteed (GXG)** |
| Express Mail Intl. | Priority Mail Express International |
| Priority Mail Intl. | Priority Mail International |
| First-Class Mail Intl | First-Class Package International Service** |
| Express Mail Sunday/Holiday Delivery | Priority Mail Express 1-Day Sunday/Holiday Delivery |
- 'Standard Post' does not return rates for zones 1-4 you need to have another method turned on.
- Addresses in the same state won't use 'Priority Mail 2-day' only 'Priority Mail 1-day'. Best practice is to label them both 'Priority Mail' so the customer doesn't know the exact method.
- 'First-class Mail Parcel' only works up to 13oz so you have to have other methods turned on for higher weight packages.
