How to download the label in Pré-Postagem
The Pré-Postagem platform (PPN) needs an active Meu Correios account. The tracking code is issued immediately, before you go to a branch.
- 1Sign in to Meu Correios and open the Pré-Postagem platform.
- 2Create the pre-posting: recipient, service and package dimensions. With no invoice, fill in the content declaration on its own tab.
- 3Finish the pre-posting, accepting the terms about which branches accept it.
- 4In the pre-postings panel, open the item's detail and print the addressing label.
What lands in your Downloads folder
A PDF holding the addressing label, following Correios' own addressing guide. There is no ZPL option and no 4x6 roll option — that gap is why this page exists.
Why there is no ZPL from Correios
The answer is in Pré-Postagem's own FAQ: printing self-adhesive labels in the 100x150 and 100x80 formats is still in development. Until then, what the platform hands you is the PDF label, sized for ordinary paper.
The legacy SIGEP Web has the same limitation. So there's no thermal-printer setting to hunt for — on this platform it doesn't exist yet.
Converting the PDF to ZPL for a thermal printer
Drop the Correios PDF onto the converter below. Each page becomes an ^XA…^XZ block with the label drawn at high resolution, ready to send to a Zebra, an Elgin or any thermal printer that speaks ZPL.
Pick the density before converting: 8 dpmm (203 dpi) is the e-commerce thermal standard; use 12 dpmm (300 dpi) if yours is a 300 dpi model. The PDF is rasterized at that resolution, so the barcode comes out as sharp as the printer can manage — without the driver rescaling that smears the bars.
The whole conversion happens in your browser. The PDF, with your customer's address on it, is never uploaded.
Printing the PDF directly, without converting
If your printer doesn't speak ZPL, or you'd rather not convert, you can print the PDF normally — with the usual care: 100% scale, no margins, and the correct paper size set in the driver.
The mistake that gets labels rejected most often is printing with “fit to page”: the barcode shrinks with everything else and the scanner at the counter won't read it.
What the generated ZPL is (and isn't)
The converted label is a high-resolution graphic inside a compressed ^GF command, not separate text fields. Perfect for faithful printing, bad for editing.
If you need Correios labels with editable fields — to build your own template in your system — generate the ZPL natively there instead of converting the PDF.
