Verified Accounts for Česká pošta

A U.S. executive order requires duty to be paid on all shipments entering the U.S. As of July 24, 2026, the duty prepayment threshold for postal shipments has risen from $800 to $2,500 USD. If you're a business shipping regularly to the United States via Česká pošta, a Verified Account lets you generate Declaration IDs and remit duties without manual intervention on each shipment.

Unlike the consumer-facing Prepay app, a Verified Account is designed for volume shippers. Declaration IDs are generated via direct API integration or a Google Sheets tool — you then upload shipment data to Česká pošta's system to receive tracking numbers.

If you ship occasionally, you can use the Zonos Prepay app instead.

What is a Verified Account? 

With a Verified Account, Zonos calculates, collects, and remits duties directly to U.S. Customs and Border Protection (CBP) on your behalf. This fulfills the prepaid duty requirement for postal shipments under $2,500 USD entering the U.S.

Here's how it fits together:

1. You generate a Declaration ID from Zonos (via API or Google Sheets).
2. You submit the Declaration ID to Česká pošta with your shipment data.
3. Česká pošta links the Declaration ID to a tracking number and processes your shipment.
4. Zonos invoices you for duties and clearance fees.

Next steps 

• Account setup — Create your account, add a payment method, and connect via API or Google Sheets.

Frequently asked questions 

Do I need a subscription for a Verified Account?

No. A Verified Account is free. You are only billed for duties and the clearance fee on each U.S.-bound shipment.

What is included in a Verified Account?

• Declaration ID generation for each shipment (via API or Google Sheets)
• Access to Dashboard tools, including the Item Quoter for estimating duty costs
• Invoicing for duties and clearance fees directly from Zonos

What will I be charged by Česká pošta vs. Zonos?

Česká pošta does not charge additional fees through Zonos. Business customers receive invoices directly from Zonos for duties and clearance fees. Postage is charged separately by Česká pošta.

Does the clearance fee apply per item or per shipment?

The clearance fee applies per shipment (parcel), not per individual item.

Can I use a Verified Account for shipments over $2,500 USD?

No. As of July 24, 2026, the duty prepayment threshold has risen from $800 to $2,500 USD. Shipments over $2,500 USD follow the same process as before the executive order.

How are duties calculated when a shipment contains items from different countries of origin?

Duties are calculated per item based on its country of origin. The totals are then summed across all items in the shipment.

How are items classified when I don't provide an HS code?

When an HS code is not provided, Zonos classifies the item from its description. Providing HS codes is strongly recommended for accurate duty rates.
