Hi Courtney,

Our rate and label technology partner, Endicia, requires a separate account for expedited vs non-expedited postage. This two-account model allows us to enable the best available rates for the services that qualify for our extra discounts.

First Class mail (non-expedited) is handled differently by USPS and the postage balance is deposited directly into a trust account with USPS. These requirements do not apply to expedited postage and thus a separate account is created to hold these funds. The expedited account also includes the extra discount on the eligible services.

Each Endicia account provides access to specific USPS services:

**Endicia First Class Domestic**:

All Domestic First Class, Media Mail, Parcel Select

**Endicia Int'l and Expedited**:

All Domestic and International Priority Mail and Express Priority Mail, International First Class

If you happen to add too much postage to one of the accounts, unfortunately, the amount cannot be transferred. If you will eventually use the postage, we recommend you leave the account as is. If you will not eventually use the postage then you can close the corresponding Endicia account for a refund. Then, if you need to ship via those methods at a later date, you can open a new Endicia account of that type. More about this process can be found in the article linked below:

You can also track all of your postage purchases by logging into each of your Endicia accounts at www.endicia.com using these steps:

I hope that helps clarify things.  If you have further questions, please let us know!
