Question 1

What payment methods do you accept?

Accepted Answer

Bitcoin, Ethereum, USDT (TRC20/ERC20), USDC, Litecoin, Solana, Monero and Zcash. Credit card is coming soon. No KYC required for crypto checkout.

Question 2

Why is BitPayPostage cheaper than USPS retail?

Accepted Answer

We use commercial rates plus a small service fee. For most flat-rate packages you'll pay close to USPS retail. Heavier packages and Priority Express are usually cheaper than the post office.

Question 3

How do refunds work for unused shipping labels?

Accepted Answer

Unused labels can be voided within the carrier's window — typically 14-28 days. Voided labels are refunded as account credit (not cash). Non-refundable if the label has been scanned by the carrier.

Question 4

Do you offer a shipping API?

Accepted Answer

Yes. Public REST API at /api/v1 with x-api-key authentication. Endpoints for rates, label creation, tracking, and address validation. Used by third-party shopping carts and crypto checkouts.

Question 5

What carriers are supported?

Accepted Answer

USPS is available to every account, including international services that hand off to Correos, Canada Post, Royal Mail, Australia Post and other destination postal services. FedEx domestic is available to verified accounts on request. UPS is temporarily unavailable and is being restored.

Question 6

Can I print labels at different sizes?

Accepted Answer

Yes. Choose 4×6 thermal (Rollo, Dymo, Zebra), 8.5×11 letter for desktop printers, 2-per-page for Avery sticker sheets, or A6 for international thermal.
