You can buy USPS postage online as physical stamps, a package label or authorized PC Postage output; you cannot legally create free printable postage from an image file.
Three legitimate online purchase paths
| Path | What you receive | Typical task |
|---|---|---|
| USPS Postal Store | Physical stamps or stamped stationery delivered to you | Letters and future mailing supply |
| USPS Click-N-Ship | A paid address-and-postage label | Eligible packages and services |
| Authorized PC Postage provider | Provider-approved postage indicia or labels | Business and integrated shipping workflows |
The output determines how it is used. A package label should not be described as a sheet of adhesive stamps, and an image of a stamp is not proof of payment.
Before you pay
- Identify whether the item rates as a letter, flat or package.
- Measure and weigh the finished mailpiece.
- Confirm the provider and postage system are authorized for the output.
- Review the address, service, ship date, tracking and total cost.
- Check the provider’s refund and reprint rules before printing.
Printing and deposit
Use a clear printer output at the intended scale. Keep the full barcode and postage indicium visible, remove old labels, and do not alter paid output. Deposit options depend on service, size, contents and whether counter acceptance is required.
Some services offer commercial prices through an approved online workflow, but that is not the same as an unexplained discount on physical stamps. Compare the complete transaction rather than assuming every online option is cheaper.
Common misleading offers
- “Downloadable postage stamps” that are only decorative graphics
- Free stamp templates presented as paid postage
- Labels sold without a verifiable transaction or tracking record
- Altered, duplicated or previously used indicia
For the broader distinction among stamps, meters, labels and permits, use the prepaid postage guide.
